Foreword
The consensus mechanism is one of the important elements of the blockchain and the core rule of the normal operation of the distributed ledger. It is mainly used to solve the trust problem between people and determine who is responsible for generating new blocks and maintaining the effective unification of the system in the blockchain system. Thus, it has become an everlasting research hot topic in blockchain.
This article starts with the concept and role of the consensus mechanism. First, it enables the reader to have a preliminary understanding of the consensus mechanism as a whole; then starting with the two armies and the Byzantine general problem, the evolution of the consensus mechanism is introduced in the order of the time when the consensus mechanism is proposed; Then, it briefly introduces the current mainstream consensus mechanism from three aspects of concept, working principle and representative project, and compares the advantages and disadvantages of the mainstream consensus mechanism; finally, it gives suggestions on how to choose a consensus mechanism for blockchain projects and pointed out the possibility of the future development of the consensus mechanism.

The picture above shows 14 relatively mainstream consensus mechanisms summarized by a geek Hasib Anwar, including PoW (Proof of Work), PoS (Proof of Stake), DPoS (Delegated Proof of Stake), LPoS (Lease Proof of Stake), PoET ( Proof of Elapsed Time), PBFT (Practical Byzantine Fault Tolerance), SBFT (Simple Byzantine Fault Tolerance), DBFT (Delegated Byzantine Fault Tolerance), DAG (Directed Acyclic Graph), Proof-of-Activity (Proof of Activity), Proof-of- Importance (Proof of Importance), Proof-of-Capacity (Proof of Capacity), Proof-of-Burn ( Proof of Burn), Proof-of-Weight (Proof of Weight).
Next, we will mainly introduce and analyze the top ten consensus mechanisms of the current blockchain.
》POW
-Concept:
Work proof mechanism. That is, the proof of work means that it takes a certain amount of computer time to confirm the work.
-Principle:
Figure 7 PoW work proof principle
📷
https://preview.redd.it/xupacdfc4db51.png?width=554&format=png&auto=webp&s=3b6994641f5890804d93dfed9ecfd29308c8e0cc
The PoW represented by Bitcoin uses the SHA-256 algorithm function, which is a 256-bit hash algorithm in the password hash function family:
Proof of work output = SHA256 (SHA256 (block header));
if (output of proof of work if (output of proof of work >= target value), change the random number, recursive i logic, continue to compare with the target value.
New difficulty value = old difficulty value* (time spent by last 2016 blocks /20160 minutes)
Target value = maximum target value / difficulty value
The maximum target value is a fixed number. If the last 2016 blocks took less than 20160 minutes, then this coefficient will be small, and the target value will be adjusted bigger, if not, the target value will be adjusted smaller. Bitcoin mining difficulty and block generation speed will be inversely proportional to the appropriate adjustment of block generation speed.
-Representative applications: BTC, etc.
》POS
-Concept:
Proof of stake. That is, a mechanism for reaching consensus based on the holding currency. The longer the currency is held, the greater the probability of getting a reward.
-Principle:
PoS implementation algorithm formula: hash(block_header) = Coin age calculation formula: coinage = number of coins * remaining usage time of coins
Among them, coinage means coin age, which means that the older the coin age, the easier it is to get answers. The calculation of the coin age is obtained by multiplying the coins owned by the miner by the remaining usage time of each coin, which also means that the more coins you have, the easier it is to get answers. In this way, pos solves the problem of wasting resources in pow, and miners cannot own 51% coins from the entire network, so it also solves the problem of 51% attacks.
-Representative applications: ETH, etc.
》DPoS
-Concept:
Delegated proof of stake. That is, currency holding investors select super nodes by voting to operate the entire network , similar to the people's congress system.
-Principle:
The DPOS algorithm is divided into two parts. Elect a group of block producers and schedule production.
Election: Only permanent nodes with the right to be elected can be elected, and ultimately only the top N witnesses can be elected. These N individuals must obtain more than 50% of the votes to be successfully elected. In addition, this list will be re-elected at regular intervals.
Scheduled production: Under normal circumstances, block producers take turns to generate a block every 3 seconds. Assuming that no producer misses his order, then the chain they produce is bound to be the longest chain. When a witness produces a block, a block needs to be generated every 2s. If the specified time is exceeded, the current witness will lose the right to produce and the right will be transferred to the next witness. Then the witness is not only unpaid, but also may lose his identity.
-Representative applications: EOS, etc.
》DPoW
-Concept:
Delayed proof of work. A new-generation consensus mechanism based on PoB and DPoS. Miners use their own computing power, through the hash algorithm, and finally prove their work, get the corresponding wood, wood is not tradable. After the wood has accumulated to a certain amount, you can go to the burning site to burn the wood. This can achieve a balance between computing power and mining rights.
-Principle:
In the DPoW-based blockchain, miners are no longer rewarded tokens, but "wood" that can be burned, burning wood. Miners use their own computing power, through the hash algorithm, and finally prove their work, get the corresponding wood, wood is not tradable. After the wood has accumulated to a certain amount, you can go to the burning site to burn the wood. Through a set of algorithms, people who burn more wood or BP or a group of BP can obtain the right to generate blocks in the next event segment, and get rewards (tokens) after successful block generation. Since more than one person may burn wood in a time period, the probability of producing blocks in the next time period is determined by the amount of wood burned by oneself. The more it is burned, the higher the probability of obtaining block rights in the next period.
Two node types: notary node and normal node.
The 64 notary nodes are elected by the stakeholders of the dPoW blockchain, and the notarized confirmed blocks can be added from the dPoW blockchain to the attached PoW blockchain. Once a block is added, the hash value of the block will be added to the Bitcoin transaction signed by 33 notary nodes, and a hash will be created to the dPow block record of the Bitcoin blockchain. This record has been notarized by most notary nodes in the network. In order to avoid wars on mining between notary nodes, and thereby reduce the efficiency of the network, Komodo designed a mining method that uses a polling mechanism. This method has two operating modes. In the "No Notary" (No Notary) mode, all network nodes can participate in mining, which is similar to the traditional PoW consensus mechanism. In the "Notaries Active" mode, network notaries use a significantly reduced network difficulty rate to mine. In the "Notary Public Activation" mode, each notary public is allowed to mine a block with its current difficulty, while other notary public nodes must use 10 times the difficulty of mining, and all normal nodes use 100 times the difficulty of the notary public node.

-Representative applications: CelesOS, Komodo, etc.

》PBFT
-Concept:
Practical Byzantine fault tolerance algorithm. That is, the complexity of the algorithm is reduced from exponential to polynomial level, making the Byzantine fault-tolerant algorithm feasible in practical system applications.
-Principle:
Figure 9 PBFT algorithm principle
📷
https://preview.redd.it/8as7rgre4db51.png?width=567&format=png&auto=webp&s=372be730af428f991375146efedd5315926af1ca
First, the client sends a request to the master node to call the service operation, and then the master node broadcasts other copies of the request. All copies execute the request and send the result back to the client. The client needs to wait for f+1 different replica nodes to return the same result as the final result of the entire operation.
Two qualifications: 1. All nodes must be deterministic. That is to say, the results of the operation must be the same under the same conditions and parameters. 2. All nodes must start from the same status. Under these two limited qualifications, even if there are failed replica nodes, the PBFT algorithm agrees on the total order of execution of all non-failed replica nodes, thereby ensuring security.
-Representative applications: Tendermint Consensus, etc.

India: Blockchain And Data Privacy: An India Perspective

Link to Mondaq: https://www.mondaq.com/india/fin-tech/978488/blockchain-and-data-privacy-an-india-perspective

A. Introduction

As a sequel to the first paper of Blockchain & Law article series titled 'A New Digital Order - Unveiling the Interplay of Law & Blockchain Technology', this paper explores the inter-operability of India's data privacy regime and blockchain technology. In this regard, recording of a webinar conducted on 'Blockchain & Data Privacy: An India Perspective' by the AKS Partners can be viewed on YouTube here.

B. Data privacy in India

Constitution of India

Article 21 of the Indian Constitution is a comprehensive, all-encompassing provision that inheres within itself basic, fundamental rights that are absolutely essential to the existence of a human being with dignity and personal liberty. In the judgment of K.S. Puttaswamy v. Union of India,1 a nine-judge bench of the Honourable Supreme Court of India held that the right to privacy falls within the contours of Article 21 and is incidental to life and personal liberty. This right to privacy includes the right to data protection and privacy.

Information Technology Act, 2000

In India, data privacy is governed by the Information Technology Act, 2000 ("IT Act") and the Information Technology (Reasonable security practices and procedures and sensitive personal data or information) Rules, 2011 ("SPDI Rules"). Sections 43A (Compensation for failure to protect data) of the IT Act provides a statutory right to a data provider to claim compensation for unapproved disclosure of information (including in breach of a contract). Under Section 72A (Punishment for disclosure of information in breach of lawful contract) of the IT Act, wherever any person including an intermediary discloses information obtained under a lawful contract without consent shall be punished with imprisonment or with fine or both.

SPDI Rules

The SPDI Rules constitute a set of basic obligations to be adhered to in circumstances where sensitive data is being collected. It may be noted that the SPDI Rules apply only to 'Sensitive Personal Data or Information'.2 The SPDI Rules lay down guidelines for collection (Rule 5) and transfer of information (Rule 7) and also mandatorily require body corporates to adopt and implement a policy for privacy and disclosure of information (Rule 4).
On 24 August 2011, the Ministry of Electronics and Information Technology issued a clarification to the SPDI Rules ("Regulatory Clarification"). The Regulatory Clarification states that the SPDI Rules are applicable only to body corporates or persons located within India. Also, where a body corporate deals in data of any legal entity located within or outside India under a contractual arrangement, the SPDI Rules pertaining to collection (Rule 5) and disclosure of information (Rule 6) would not apply. It was also clarified that requirement to obtain written consent under Rule 5(1) of the SPDI Rules includes electronic consent as well.

The Personal Data Protection Bill, 2019 ("Bill")

The Bill is inspired from and is in many ways a replica of the European Union's General Data Protection Regulations ("GDPR"). The Bill lays down several provisions including in relation to crossborder transfer of data, sandboxing, privacy by design and introduces a more robust set of obligations for entities handling sensitive personal data. The Bill is currently pending before a Joint Parliamentary Committee. The Bill applies to and categorises data into 'Personal Data', 'Sensitive Personal Data' and 'Critical Personal Data'.

Sectoral regulations

Regulated sectors such as telecom and financial services have separate obligations of confidentiality which restricts disclosure and transfer of customer personal information and mandates use of such information only in the manner agreed with the customer. Certain sectoral regulators (like Reserve Bank of India) also mandate data localisation.

C. Blockchain technology and data privacy

For details on the working of a blockchain network, please refer to our previous paper here.
Coverage
The Bill defines 'Personal Data') as 'data about or relating to a natural person who is directly or indirectly identifiable'. This means where the origins of the data cannot be traced down to a natural person, the data would cease to be 'Personal Data'. Resultantly, storing the data in a manner where it cannot be traced to a natural person (including by introducing and implementing robust methods to address re-identification risks) may prove beneficial in reducing a blockchain network's interaction with data privacy regulations (such as by encryption or anonymisation of Personal Data).
Public v. Private Blockchain
Private blockchain which restricts and regulates network participation appears to be a more preferable fit when it comes to ensuring compliance with data privacy laws. Public blockchains with permissionless borders pose greater difficulty in procuring every participant to agree on and comply with relevant rules on protection of personal data.
Stakeholders
The Bill identifies three categories of stakeholders (similar to GDPR) viz. Data Principals, Data Fiduciary and Data Processor. The SPDI Rules only provides for data provider and body corporate or person collecting data. The term 'Processing' has been defined to include collection, storage, retrieval, adaptation, disclosure etc. (Section 3(31)). Accordingly, any data stored or transmitted on blockchain will amount to processing.
Blockchain network is a decentralised system with each node / miner (i.e. network participant) spread all over the world. There is no clear demarcation between a Data Principal and a Data Fiduciary or a Data Processor over a blockchain network. The way the network functions, no single person can be said to be in-charge of the network thereby making it all the more problematic for regulators to fix the compliance burden on a party. Accordingly, the question of determining the identity status and fixing liability of various participants attains significance and complexity over a distributed ledger network like blockchain.
Each node over the network functions as a Data Processor on account of participation in the verification of the data. At the same time one or more of such nodes may also be acting as a Data Principal. With respect to mining over the network while it is a single miner who is able to formulate a valid hash, all the other miners also participate in the mining activity when they attempt to arrive at the winning lottery number. Thus making such miner also a Data Processor. While fixing liability on a private blockchain network that restricts the number of network participants is comparatively less complex, the same would be quite challenging on a public blockchain network, such as Bitcoin. With regard to identifying the status and roles, the guidance issued by French data protection authority ("CNIL Guidance")3 in the context of GDPR is useful. The CNIL Guidance categorises blockchain actors into the following groups: (a) participants with full read and write access to the data; (b) participants with read only access; and (c) miners that validate the transactions.
Participants falling in category (a) above are Data Controllers (equivalent to a Data Fiduciary under the Bill) while categories (b) and (c) are not.
Collection and processing of data over a blockchain network
The Bill sets out a number of obligations that have to be performed by the Data Fiduciaries, some key compliances being, obtaining consent of the data principals, retaining the data only till absolutely necessary (Storage Limitation), providing notice to the Data Principals, ensuring data is used only for the purpose (which has to be specific, clear and lawful) for which it has been taken (Purpose Limitation). Rule 5 of the SPDI Rules also lays down similar obligations for collection of data. Key concerns that the inherent and intrinsic nature of the blockchain technology raises are as under:
Firstly, with respect to the Storage Limitation principle, the immutable nature of the technology prevents the data from being deleted once the purpose has been fulfilled.
Secondly, given the decentralised nature of blockchain, it becomes challenging to determine the exact purpose for which data is collected over such a widespread network and who is to keep a check that the data so collected is used only for such predefined purposes.
Thirdly, it is commonly argued that the network participants over a blockchain impliedly consent while sharing their data. This may not however fulfil the requirements under the Bill which requires consent to be clear, through an affirmative action. This gives birth to concomitant regulatory issues over a decentralised system as to who shall oblige with these compliances under the law and who should be made responsible / liable for any lapses in compliance.
Lastly, the Bill also proposes certain additional requirements such as transparent and fair processing and the Purpose Limitation. The blurred distinction in the status of identities in blockchain makes determining purpose and manner of processing challenging.
A detailed governance framework setting out roles and responsibilities, off-chain and on-chain personal data, may provide useful guidance towards addressing the aforementioned concerns.
Key rights of Data Principals

Right to Confirmation and Access

The Bill entitles the Data Principals to seek information regarding the types and nature of personal data stored with the Data Fiduciaries, or to ascertain the nature of processing activities that has been undertaken on his/her data, or seek a brief summary of processing activities undertaken. While enforcement of this right may not be technically difficult, however, blockchain networks may establish a proper governance framework that delineates a specific authority to pass over the requisite data to the data principal as and when asked for. The network may also consider laying out methods of searching and accessing the necessary information which may be de-encrypted with the use of the private key.

Right to Correction

Section 18 of the Bill and Rule 5 of the SPDI Rules provides the right to rectify or correct the data. Given the immutable nature of the decentralised ledger maintained on a blockchain, exercising this right may not be compatible. To accomplish alteration/correction of data would be a burdensome task since it will require a majority of nodes to come together to identify the data, alter and re-hash not just the concerned block but also all previous blocks as well. Alternatively, a new block with corrected information may be added once verified through the consensus mechanism.

Right to be Forgotten

The Bill introduces 'Right to be Forgotten' ("RTF"). RTF entitles data principals to request the removal of his/her personal data, without undue delay, from any business's storage. RTF has been in loggerheads with the inherent immutability of blockchain technology. Across jurisdictions the term 'forgotten' has been pegged with erasure and is construed in various senses in different jurisdictions, ranging from data anonymisation,4 destruction of hardware,5 putting data beyond use.6
Given the distinction within the types of blockchain, the modes for exercising RTF are uniform by and large. A widely discussed solution is the destruction of the private key, thereby rendering the data encrypted by a public key inaccessible.7 Owing to the setup of blockchain, a Data Principal may reach out to any entity in the chain that qualifies as a Data Fiduciary to enforce their rights. Similar
to the Google-Spain case,8 wherein data subject's action against Google remained unaffected by the fact that the data could have been removed by the newspaper's website itself.9 However, the nature of a public blockchain network that does not identify a central authority might prove somewhat problematic where the data principal seeks to enforce his/her right.
As countries are yet to formulate policies with respect to regulation of blockchains, some other alternatives for exercising RTF can be programming chameleon hashes, zero knowledge proofs or a censorable blockchain, as the same would be 'forgetful'.10
Cross-Border Transfer of Data
Chapter VII of the Bill, which deals with restrictions on cross-border transfer of data, requires a copy of the Sensitive Personal Data to be stored domestically while Critical Personal Data must exclusively be processed and stored in India. However, these clear demarcations blur when applied to a blockchain ecosystem where storage and processing of data can be universal. Transfer of Sensitive Personal Data, requires explicit consent and the transfer must be under a contract or an intra-group scheme approved by the data protection authority (envisaged to be established under the Bill). While both of these requirements may get fulfilled over a private blockchain easily, a public blockchain due to undefined groups and lack of a central entity / authority may find it more challenging to implement adequate safeguards on restricting such transfer. Over a private blockchain the central body may enter into e-contracts with any number of participants and also obtain their explicit consent.
Under the present regime, Rule 7 of the SPDI Rules provides that a transfer outside India may only be allowed where the country offers the same level of protection to the data. Again, enforcing this may be challenging over a public blockchain network comprising of thousands of nodes across borders. An in-built cross-border transfer consent clause in the governance framework or otherwise may also provide the needed legitimacy from the perspective of data privacy.

D. Jurisdictional Issues

The present uncertainty in law (including lack of adequate legal provisions) has resulted in jurisdictional issues concerning the domestic and transnational presence of the blockchain network. While Section 1(2) read with Section 75 of the IT Act accords limited extra-territorial applicability to the Act, the SPDI Rules, as mentioned in the Regulatory Clarification are applicable only to body corporates or persons located in India. Consequently, blockchain technology may need to comply with the IT Act to a certain extent, while, the mandate under the SPDI Rules will bind only the nodes/miners operating from India. As a result, the network participants operating outside India on the same blockchain will not be required to comply with the SPDI Rules or IT Act.
Section 2 of the Bill affords extra-territorial application but only in certain limited circumstances viz. where the processing which takes place outside India is in connection with any business in India, or which involves the profiling of individuals within India. This will result in a subjective assessment of blockchains and its purposes in order to ascertain the applicability of the provisions of the Bill.
The Civil-Commercial Courts in India, have applied the test as to whether a website is an 'interactive website'11 for determination of jurisdiction, in relation to websites that do not have a physical place of business in a jurisdiction.12 In other words, wherever a website facilitates or even intends to facilitate active trade / commercial transactions in jurisdictions where it does not have a physical place of business, in such cases cause of action, if any, arises in all such jurisdictions where the website operates interactively. However, applying such a test on a blockchain network may not be so straightforward. The intrinsic nature of the blockchain technology allows for processing and storage of data at multiple domestic and international jurisdictions simultaneously. Resultantly, in both domestic as well as international, identification of the place of cause of action becomes complex. The complexity increases as identification of the individuals processing and storing data (nodes) would require de-anonymisation.
The determination of applicable laws will also depend on the nature of a blockchain network. It is practically more difficult to regulate a public blockchain network than a private blockchain network. In a private blockchain the architect/controlling entity may determine the governing laws or the governance framework may provide for a governing law.
In light of the foregoing, it may come as a mammoth task for governments to enforce their respective data protection and cyber-security legislations against such transnational networks without consensus on a multi-national treaty suggesting a model law to regulate the use of blockchain networks. In the alternative, laws may promote self-regulation by merely identifying basic tenets of regulations like governing law, data privacy, certification etc. Non-compliance may include compulsory suspension/termination of participation rights of nodes or blocking access to blockchains which do not provide for adequate self-regulation.
The developers of blockchain networks may consider incorporating dispute resolution and regulatory mechanisms as integral parts of the networks. The developers may also consider coding networks with peer-to-peer decentralized courts such as 'kleros' or 'codelegit' as part of a network's dispute resolution process.

E. Way forward

Blockchain technology carries the potential of disrupting business operations right from supply, manufacturing, logistics and final consumption especially in a post Covid-19 era. Please refer to our previous article on use cases of blockchain here. Accordingly, it is crucial that data privacy laws (with adequate concessions, where necessary) be treated as an enabler and not inhibitor to continued adoption of blockchain technology. Certain additional rights like data portability and right to withdraw consent adds to the complexity of having a compliant blockchain network. Certain obligations like mandatory registration may also be problematic if the government notifies certain blockchain network as a significant data fiduciaries.
Set out below are few indicative measures towards harmonious application of data privacy laws and blockchain technology:
1) Every blockchain network must provide a detailed governance framework that is in alignment with the basic requirements under data privacy regulations. Such a framework would have to be binding on all participants over a blockchain network, stating all rights, obligations and duties of parties, including a detailed mechanism for communication, security measures, cross-border data transfer, and grievance redressal and may even set out applicable laws etc.
2) Such a self-governance framework could also include a privacy by design policy and provisions for Data Protection Impact Assessment (as set out in Chapter VI of the Bill).
3) 'Pruning' is used for situations where historical blocks of data beyond a certain timeline are deleted. Similarly, where data has to be altered or rectified, the same may be done by 'forking' where data is altered or deleted, the hash changed and a new fork is created. However, over a public blockchain Pruning and Forking can be challenging and may require a huge amount of computing consensus.
4) To ensure the safeguarding of right to privacy a Memory Optimized and Flexible Blockchain (MOF-BC) can be considered as an effective measure. It enables the IoT (Internet of Things) users and service providers to edit their transactions, thereby altering the details of data entry.13

Is All Cryptocurrency Mining Harmful to Our Environment?

Is All Cryptocurrency Mining Harmful to Our Environment?

https://preview.redd.it/bl0g74xrwm651.png?width=1400&format=png&auto=webp&s=13a69a7971ef9dc39dd3c571687331f77c6b52c1
Blockchain technology is now widely adopted in many fields, including banking, finance, administration, legal affairs, and investments. It can also be used for health and environment, and it shows its potential as it is utilized more and more worldwide. In the case of FLETA, we have developed a blockchain-based eCRF system, a clinical trial data collection tool, that helps people manage clinical trial data and contribute to the healthcare industry.
However, at the same time, blockchain technology is blamed for its harmful influence on the environment. The reason for it is cryptocurrency mining. It is known that Bitcoin and many other cryptocurrencies are not entirely eco-friendly.
The only way to create Bitcoins, since there is no central bank that issues the digital asset, is through miners. The miners solve cryptographic problems by using software specially designed for mining. Of course, energy is used when miners use the software to mine those cryptocurrencies.
In the case of Bitcoin, only the fastest miner who solves the mathematical problem gets the mining reward, and miners compete to be the one. As the price of Bitcoin has increased, more people have participated in mining. This phenomenon caused severe competition among the miners, and the problems miners have to solve became much more complicated. As a result, miners need high-performance mining equipment that requires more energy than before to win the competition. Moreover, an increased number of miners and difficulty of problems also provoke a large amount of electricity consumption. Cryptocurrency miners are responsible for solving provided math problems, which is obtained using software specially designed to solve cryptographic problems. Of course, energy is used when miners use software for mining those cryptocurrencies.
In the case of Bitcoin, only the fastest miner who solves the mathematical problem gets the mining reward, and miners compete to be the one.

As a result, miners need high-performance mining equipment that requires more energy than before to win the competition. Moreover, an increased number of miners and difficulty of problems also provoke a large amount of electricity consumption.

How much electricity is used for Bitcoin mining?

According to Digiconomist, it estimates that currently, the electricity expenditure in Bitcoin mining exceeds that of countries such as Denmark, Bulgaria, and Belarus, and accounts for more than 25% of Holland’s energy consumption, 15% of Australia or 10% of the United Kingdom.
For example, according to the International Energy Agency (IEA), cryptocurrency is positioned as one of the businesses that consume the most electricity worldwide. If these cryptocurrencies were a country, they would be ranked 41st nation that consumes much power annually, according to Digiconomist.

So How Can We Use The Technology to Solve Our Problem?

As mentioned, cryptocurrency mining consumes a lot of energy, which inevitably harms the environment. Then, how can we prevent this problem from the blockchain industry?
One of the solutions is choosing one of the many alternatives to the traditional Proof of Work consensus protocol. Proof of Stake, for instance, is far more eco-friendly since mining equipment is unnecessary.

How is FLETA Contributing to Saving the Planet

FLETA is a platform created for the deployment of decentralized applications. FLETA does not use a proof of work consensus algorithm as it has created its own. Proof of Formulation (PoF) is a new consensus model that replaces the traditional PoW. This new consensus protocol eliminates the possibility of unnecessary forks and allows blocks to be generated in a designated order.
This consensus algorithm does not require a lot of electricity, similar to Proof of Stake that is eco-friendly.
FLETA is not only infinitely scalable but also offers a high transaction processing speed using its original block design. The ability to infinitely scale is achieved through a multi sub-chain system. Whenever a DApp is created on top of FLETA, a new sub-chain is also deployed, which means that every single dApp can be operated independently and without affecting other DApps.

Conclusion

FLETA also has created an eco-friendly consensus algorithm Proof of Formulation that allows the platform to be more scalable and efficient. Developers can easily build their DApps on top of FLETA and enjoy all the benefits of the platform like higher transaction speed, scalability, and being able to operate independently.

Every 210,000 blocks, or approximately once every four years, Bitcoin undergoes a halving event where the mining rewards are cut in half. The current block reward is 12.5 BTC/block, and the next halving is expected to take place on 12 May 2020. From block number 630,001, the block rewards will be reduced to 6.25 Bitcoin. This process is supposed to continue until the last Bitcoin has been mined.
Halvings are done to preserve the value of Bitcoin through the laws of supply and demand. If Bitcoins are mined too quickly, and there is insufficient market demand, their value will drop. Historically, the halvings have always positively affected the price of Bitcoin in the months and years following the event when Bitcoin reached new all-time-highs.

What is Bitcoin Mining and How Does it Work?

Bitcoin is a decentralized currency. It doesn’t use the services of a bank or another central institution to transfer the assets. Instead, Bitcoin has a blockchain and its transaction records are stored for eternity.
The people who store these transactions on the blockchain are called miners. Miners are financially incentivized to confirm transactions. The confirmations are done by solving complex computational problems. Whoever solves the problem receives a fixed reward in Bitcoin.
Likewise, Bitcoin relies on a Proof-of-Work (PoW) consensus algorithm. It bets on the strength and efficiency of the underlying hardware. PoW coins are mostly mined through GPUs and ASIC miners. In the past, Bitcoin could be mined with your PC’s CPU. The mining network wasn’t big, and the rewards were appealing. That is no longer the case. The mining difficulty has increased and today, mining is handled via countless expensive ASIC miners.
PoW mining is, therefore, profitable only to those who have made substantial hardware investments and not to the ordinary man. PoW consumes much electricity, and the Bitcoin network generates a block every 10 mins on average, which makes it more difficult for ordinary miners to get block rewards.

What is Proof of Formulation?

In the case of FLETA, it utilizes its own consensus algorithm: Proof-of-Formulation (PoF). This algorithm consists of 2 main actors:
  • Formulators — the block generators, the equivalent of PoW miners.
  • Observer Nodes — validate, confirm, and sign transactions in real-time, and prevent forks and double-spending.

Formulators

In contrast to PoW, where better hardware equipment is equal to bigger rewards, in PoF, all Formulators take part in block generation according to a pre-determined order. Once everyone has had their turn, a new mining phase starts, and all Formulators are arranged according to a new random sequence. No competition and equal mining opportunities for everyone!
To become a formulator, a user needs to register and stake 200,000 FLETA tokens at the FLETA Formulator Portal or FLETA Wallet. There is a maintenance fee to be paid every month. The mining is performed through FLETA cloud mining, and the user doesn’t need to set up a server on his own. Formulators can be upgraded for more efficiency and better performance. This is explained in more detail here.

Observer Nodes

Observers secure the network and prevent DDoS attacks. 5 Observers are assigned to each Formulator group. At least 3 of them are required to sign the transactions and include them in the blockchain. This system makes a fork impossible because the first block with three signatures will be included in the blockchain.

In the End

Proof-of-Formulation is fast, fair, and secure, thanks to the watchful eyes of the Observer Nodes, and their bond with Formulators. The results show that PoF allows 14,000 transactions/second and a block creation time of only 0.5 seconds/block.

What are the benefits of Crypto Mining?

What are the benefits of Crypto Mining?

https://preview.redd.it/q6xfuxvtmjv41.png?width=875&format=png&auto=webp&s=b092bca718f6cba3ae8c327a54952f4e65c7ed25
If you’ve ever heard the word cryptocurrency, then you’ve probably heard about the mining as well. If you still don’t know what cryptocurrency mining is and about profitable, keep reading!
In order to understand crypto mining, you need to fully understand what a cryptocurrency is first. Unlike traditional currencies (aka fiat currency), a cryptocurrency is a digital asset that works in a decentralized way; it does not require a bank or a third-party to operate. Someone can send someone else a cryptocurrency directly without any third-party involved.
The first ever cryptocurrency created was Bitcoin.
Every single cryptocurrency has a blockchain, which is an immutable digital ledger. A single transaction is recorded on the blockchain permanently, which no one can edit or delete it randomly.
A blockchain works by incentivizing miners to confirm the authenticity of each transaction. A person who confirmed the authenticity of the transaction, get the cryptocurrency as a reward.
Since the cryptocurrencies are based on cryptography, the miners need to solve extremely complicated mathematical problems to verify each transaction. They are incentivized to do it because they are rewarded for it.
Anyone can participate in mining from anywhere in the world as long as they have a computer. When the number of miners increases, it allows cryptocurrencies to be more secure. Even if an attacker would want to attack the blockchain network, somehow, an attacker needs to know 51% or more miners. Since the miners are spread around the world, this task is close to impossible and most likely not economically viable.

Types of Crypto Mining

Bitcoin was the first cryptocurrency to introduce the Proof-of-Work (PoW) consensus algorithm, where users have to solve complex mathematical problems in order to process transactions and secure the whole network.
Bitcoin was quite easy to mine at first, and you could do it with your CPU, there was no need for special equipment, and the rewards were huge. However, today, Bitcoin’s mining difficulty has increased considerably, and users need specialized and expensive equipment to mine it.
There are four main types of mining when it comes to the PoW algorithm. There is a CPU, GPU, ASIC, and Cloud mining.
The first three are essentially the same, but they use different parts of your computer. There are some cryptocurrencies specifically created to be mined only through CPU and to be ASIC resistant. Other cryptocurrencies can be mined through all three methods.
Cloud mining, on the other hand, is a process where a user basically pays to rent out a mining machine somewhere else. You don’t have to buy the equipment physically but it is wise to carry out due diligence and research into who and what you are paying for.

Proof of Stake ‘Mining’

With the introduction of the Proof-of-Stake (PoS) consensus algorithm, cryptocurrency mining changed forever. In this case, users don’t have to solve computationally intensive puzzles. In PoS-based cryptocurrencies, the creator of blocks is chosen via random selection or wealth.
Validators in the PoS consensus have to lock up some of their coins as a ‘stake’ and will get rewarded for it.
There are many benefits over the traditional PoW like lower cost and more energy efficiency. Additionally, because PoS encourages users to hold the coin in the wallet, it stabilizes the price a bit more than conventional cryptocurrencies.
Today, you can find plenty of exchanges that support staking, including the most popular exchange, Binance. The safest option, however, is always going to be staking using your own private wallet.

Proof of Formulation ‘Mining’

FLETA has developed the most innovative and newest consensus algorithms known as Proof-of-Formulation (PoF).
This PoF consensus algorithm uses something called the ‘Synchronization Group’, which allows all of the miners to mine in an orderly manner. The generating block time only takes 0.5 seconds, and the observer node checks the irregular blocks in real-time, which prevents the fork and double-spending. Furthermore, FLETA’s PoF algorithm is currently undergoing the patent process through the United States Patent Office (Application Number: 62717695).
The users can easily create a FLETA formulator through the official FLETA wallet. The minimum amount to create a single Formulator is 200,000 FLETA. The blockchain network is operated by FLETA and requires a 6-core CPU or higher.
As you created at least four Formulators, you will be able to upgrade it, which allows you to get 1.3 times more rewards.
Besides creating a Formulator, users can contribute to mining with a minimum amount of 100 FLETA.

Conclusion

Today, various mining methods exist, each with their pros and cons. However, cryptocurrency miners are still craving more convenient (and less costly) ways to earn rewards.
FLETA’s Proof-of-Formulation consensus is not only fast, but it is also highly secure the added layer of protection between observer nodes, formulator, and the synchronization group.
With plenty more to come, in terms of DApp development, games and partnerships, FLETA’s PoF is increasingly becoming the preferred consensus of many developers due to the speed, security and convenience of the platform.

Is Genesis Mining worth it? I created a Genesis Mining profitability calculator in Google sheets to find out.

TL;DR: I attempt to overcome the pitfalls of forecasting genesis mining contract profitability for Ethereum, Monero, and Zcash.
The original Medium post can be found here: https://medium.com/@spreadstreet/is-genesis-mining-worth-it-a-genesis-mining-profitability-calculator-youll-actually-use-a06d916bf7bc
BitPay is on pace to process over $1B annually in bitcoin payment acceptance and payouts, and has already grown their payments dollar volume 328% year-over-year, according to a recent blog post on the BitPay website.
The very nature of cryptocurrencies requires transactions to be verified by miners. What does this mean?
  1. Cryptocurrency transactions are verified by a network of nodes, then recorded in a publicly distributed ledger known as a “blockchain”, which authenticates the coins as monetary units of measurement – or money.
  2. Cryptocurrency mining refers to coins created as a reward in which the users of the network verify and record transactions on this very blockchain. Users who are able to successfully verify the transactions receive fees and rewards in the form of brand new coins.
And Genesis Mining stands as the largest cryptocurrency cloud mining company in the world.
A user can rent "hashing power" in the form of a two-year contract from Genesis for a one-time, upfront fee.
In turn, they receive daily payouts of whatever specific cryptocurrency they purchased the contract for.

THE PROBLEM

While Genesis Mining has done a great job breaking down a complex problem into an easy-to-understand business model, users consistently have one big question:
"How profitable is {x} contract?" - Everybody, ever
While the user is able to see the upfront cost, they are unable to get an idea of how many coins they will receive by the end of the contract.

WHY THE PROBLEM EXISTS

The problem exists, because of two major uncertainties surrounding cryptocurrencies:
  1. Where the price of the currency will fluctuate over time
  2. Where the network hashrate (aka, the mining power of the entire network) will fluctuate over time
Both of these inputs are extremely volatile, and have a huge degree of uncertainty in the near and distant future.
What I will attempt to do in this exercise, is build a profitability calculator for Ethereum, Monero, and Zcash. Each of these cryptocurrencies is currently available on the website as of 11/7/2017.
Each cryptocurrency has three contracts, and I will formulate 4 different scenarios to try and capture a profitability "range".
Note: Do not take any of the words in this post as financial advice or recommendations. These are merely simulations that have their own issues and pitfalls, and are not to be used as the end-all, be-all decision.

THE ASSUMPTIONS

Due to the difficulty in forecasting both price and nethash, I was forced into a few assumptions:
  1. The forecasted price method is a Monte Carlo simulation using a geometric Brownian Motion ran 1,000 times. I covered the full methodology in a prior blog post
  2. The base network hashrate follows along very closely with the movements in price. This assumption I am the least confident about, as network hash has been shown to deviate at certain times
  3. I attempt to cover the shortfall in network hash rate with two different scenarios (shown below).
  4. I assume we hold all coins until the end of the contract, and assign a value to the portfolio based on $USD
  5. I do not run any scenarios of converting a currency into another currency
  6. I do not account for any significant changes to the underlying algorithm, such as the "Casper" Ethereum update (see 'THE DIFFICULTY BOMB' below)
Obviously any slight change could drastically alter these assumptions, but let's take a look at the different scenarios.

THE SCENARIOS

Description of Scenarios
Instead of calculating just a base scenario (which every other calculator on the web does) I wanted to come up with different scenarios to get an idea of what could be.
  1. Base - Assume no change in price or network hashrate for the duration of the contract
  2. Median - Run a full 1,000 trial simulation of prices and network hash rate, and use the median values for each
  3. Conservative - The same as Median, but instead use a price forecast that is 1 standard deviation below the median price
  4. Aggressive - The same as Median, but instead use a price forecast that is 1 standard deviation above the median price

APIs USED

  1. Spreadstreet Google Sheets Add-in
  2. Bitfinex API - To pull in historical data for each currency
  3. WhatToMine API - For nethash statistics
  4. CoinMarketCap - Updated prices

ETHEREUM

The only way to utilize Ethereum is with the product from mining.
But this shortchanges the additional value of mining Ether. It is also absolutely required for securing the Ethereum network as it creates, verifies, publishes, and propagates blocks in the blockchain.
The overall term "Ethereum Mining" is the process of mining Ether. Ether is an absolute essential, as it serves as fuel for the smooth running of the Ethereum platform.
Ether is used as an incentive to motivate developers to create top notch applications.

THE DIFFICULTY BOMB

Sometime in the future (we can't be certain when), ethereum will likely switch from its proof-of-work consensus algorithm to Casper, a proof-of-stake system its developers are now in the throes of completing.
From Blockonomi:
As opposed to the PoW consensus protocol, the PoS protocol achieves consensus through stakers—sometimes referred to as minters, too—who “stake” their coins by locking them down in specialized wallets.
With these stakers at work, mining will become redundant, meaning the Ethereum network post-Casper will rely on stakers and staking pools instead of miners for its operability.
Genesis Mining has a prelim plan in place for this scenario:
The Ethererum Mining plans will run for a maximum of 24 months, however, should Ethereum (“ETH”) switch to proof-of-stake before the end of the term, we will use the leased hardware on a best-effort basis to mine the most profitable coin with that hardware for you.
Very simply put, this changes the economics of contract profitability significantly. We are going to ignore that update for now, but it may make sense to stay away from the contracts in the short-term.

ONE-YEAR PRICE FORECAST

Ethereum One Year Price Simulation
Here we can see one of 1,000 price simulations run to inform our forecast for the Median, Conservative, and Aggressive scenarios.
*Why is the price so high? This is what happens when you have a volatile currency in a simulation that does not have changes in said volatility. When a currency can move 20% in one day, it is not uncommon to see price movements like this. I mean, shit, Ethereum grew 25x in one year.

RETURN ON INVESTMENT

Ethereum Profit and ROI Comparison

VERDICT

Base performance ranges from 30% to 39% ROI, and is higher than the Median scenario by ~10%.
The conservative scenario shows a loss of between 59-62%, and the aggressive scenario shows a gain between 318% and 347%.
Difficulty bomb in the near-future presents tremendous uncertainty.

MONERO

From Cryptocompare:
Monero (XMR) is a Cryptonote algorithm based cryptocurrency, it relies on Ring Signatures in order to provide a certain degree of privacy when making a transaction. Monero is a Proof of Work cryptocurrency that can be mined with computational power from a CPU or GPU. There are currently no ASICs for Monero, which means that anyone with a computer can mine it.

THE CONTRACTS

Monero Mining Contracts Comparison

ONE-YEAR PRICE FORECAST

MoneroOne Year Price Simulation
We run the same Monte Carlo simulation to inform our forecast for the Median, Conservative, and Aggressive scenarios.
Why is the price so high? See Ethereum up above.
How is it possible for the "Conservative" scenario to be higher than the base price? Good question, and i'm glad you brought it up. The Monero currency has been not only really volatile, but drifting upwards at a pretty high rate.
The results are also being skewed by a recent uptick on November 6th where the price jumped by ~18%.
This may represent an opportunity for contract investment, but more analysis is needed.

RETURN ON INVESTMENT

Monero Profit and ROI Comparison

VERDICT

Base performance ranges from 87% to 95% ROI, with performance in the Median scenario lower by 5-6%.
The conservative scenario shows a loss of between 63-64%, and the aggressive scenario shows a gain between 795% and 832%.
To reiterate, the aggressive scenario is very much influenced by the recent uptick in volatility, so be weary of those high numbers.

ZCASH

ZCash uses Equihash as an hashing algorithm, which is an asymmetric memory-hard PoW algorithm based on the generalized birthday problem (I don't know what the hell this means, but it sounds fancy).
It relies on high RAM requirements to bottleneck the generation of proofs and making ASIC development unfeasible, much like Ethereum.

RETURN ON INVESTMENT

Zcash Profit and ROI Comparison

VERDICT

Base performance ranges from 51% to 65% ROI, and surprisingly lags the Median scenario by 4-6%.
The conservative scenario shows a loss of between 56-60%, and the aggressive scenario shows a gain between 490% and 540%.

CONCLUSION

The initial upfront costs and potential profitability are hidden when investing in hashing power contracts like Genesis Mining.
However with some robust analysis, we can get a better idea of how to assess the potential profitability of a two-year deal.
As we continue to evolve our thinking, better methods and analysis will eventually surface. Hopefully this industry can become a great avenue for side income.

GAW Miners - Liars, Frauds - A brief recap of what we know.

EDIT: I was asked by a GAW staff member to compile a list of questions the community has with/about GAW, Paybase, etc. Please provide any questions you have below and I'll have them forwarded
EDIT 2: It seems Josh is working on answering the questions I've asked and compiled. We'll see what happens when answers are released.
Hello, in the midst of this public uprising against GAW I'd like to present some facts for those of you who either:
a. Don't know who/what "GAW" is and why they're a scam,
b. Are brainwashed by Garza; those of you who genuinely believe in Paycoin and GAW Miners,
c. Don't quite have all of the information.
Note that I don't have every possible snippet of information out there, I'll just bring up some of the main points and complaints.
Pre-GAW
Ten months ago Garza was first introduced to the Bitcoin community in this post and this post.. From these posts we learn quite a bit of information regarding Garza's past; he offered false business deals to eBay sellers to partner with him. In the first article, we see that after he offered this couple "20% of his total profit" from his mining company and the couple asked for a reasonable counter-offer of $5k/month to pay their bills since they were unemployed, Garza filed a false Significantly Not As Described case on eBay, causing the couple to quite a bit of money and seriously affected their finances. The couple did some research about Garza and found this:
After looking at their old facebook profile, we saw that they were originally DirectTV salesman preying on small rural towns around New England offering people high-speed, internet and other telecom services that these people weren't able to get for whatever reason before. GAW was able to coerce MBI (Massachusetts Broadband Institute) to donate $40,000 to them for helping to bring services to everyone in the communities. Garza promised to build towers and other bullshit in these towns to help provide services, but they never did. At some point even when community leaders (one was David Kulp) repeatedly tried to get in touch with them, they never heard back.
So, it seems Garza has a knack for deceptive practices 'eh? Since the posts are so long and there's a lot to discuss, I'll let you read them and formulate your opinion on Garza. (Thanks to DidHeJust for the links to those threads).
-Early Phases
Originally, GAW showed NO proof of mining at all (not an address, block, pictures of mining hardware, pool usernames, nothing). Later on, during the Hashpoint 'mining' phase, he purchased 5 PH/s worth of mining equipment from Bitmaintech. For the short amount of time Paycoin was available for proof-of-work mining, there were tons of people renting mining rigs in order to get a cut of the "$20 Paycoins." Since the difficulty was fairly low, the prices per TH/s of these miners were very high, making it extremely easy to ROI on them. I'd be willing to bet that GAW rented out a lot of their hashpower for profit. They're currently selling the hardware they have left from this on oneminer.com.
There was also a brief period of time where you were able to purchase hardware from GAW and have it point to a pool of your choosing; however, this didn't account for too large of a portion of the hashpower they claim to have sold.
-Forums
GAW Miners owns a forum created them them, Hashtalk. This forum is heavily censored; if you attempt to inquire about some of GAW's deceptive practices, broken promises, or Paycoin design you'll either be outright banned or shadow banned (your account will remain useable to you, but nobody will be able to see any of your posts). This led to this uncensored discussion thread on Bitcointalk.
- Broken Promises
Promise 1: *"Always Profitable"**
GAW Miners claims that their Hashlets would always remain profitable and the $0.08 fee per MH/s would go down overtime. You know what GAW did instead? They kept their fees the same even when people were receiving only 1 satoshi. That's hardly profitable at all, as it's the minimum amount that they can really pay. So, they decided to move to mining Hashpoints for Paycoin (another broken promise, explained later).
Promise 2: *"Paycoin would launch with a $20 floor"**
This one is interesting. For the three months or so Hashpoint mining was available, Garza claimed that Paycoin would have a $20 floor (essentially that GAW would buy up any coin sold below $20 to keep the market place there or higher). Now, however, they've purged their censored forum of such claims so all that remains are screenshots as proof. Here's a few: https://i.imgur.com/YFXJiKB.png and https://i.imgur.com/HnotyMB.png Paycoin was traded at about $20 for a very brief period of time, but since then it's been dropping steadily, trading at just above $6/ea currently. Garza has done nothing to rectify the situation since.
Promise 3: *Large merchant support on launch**
From this thread we see that Garza promises that:
That’s right, you will be able to shop with Paycoin on the Amazon, Target, Walmart, Macy*s and Best Buy’s online stores.
A journalism website, coinfire.cf, contacted Amazon and the other companies claimed to be partnered with GAW. These companies all denied being affiliated with GAW, Amazon even threatened legal action if this continued. Once the article was published, the coinfire website was mysteriously hacked and the day after GAW threatened legal action. Read more about it here:
https://coinfire.cf/2014/11/22/is-gaw-miners-lying-about-partnerships/ and http://www.scribd.com/doc/248372603/Coinfire-Cease-and-Desist
-Censorship [Developing!!!]
At the moment GAW is taking down videos they've posted where they've made a certain "statement" on their mining.
-Paycoin
Ah, Paycoin. An altcoin plagued by delays and broken promises. Originally set to launch at $20 per coin, falsely leading people into investing money into Hashpoint miners for profit. The things Josh is doing and has done to get people to use Paycoin are laughable, I'd consider it treason against the Bitcoin community. He purchased the domain btc.com for $1,000,000 only to have it redirect to Paybase. Fun stuff 'eh? He's also claimed that his coin would be better than Bitcoin, denouncing it in order to promote his own coin. From code snippets we've seen, Paycoin's "Prime Nodes," part of the PoS system to generate new coins, has the ability to generate coins at a 350% interest rate. These wallets/stakers/controllers/nodes are only able to be controlled by GAW, of course. The code:
int64 nSubsidy = 0; int64 nRewardCoinYear = 0; // creation amount per coin-year if (primeNodeRate == 0) nRewardCoinYear = 5 * CENT; else if (primeNodeRate == 10) nRewardCoinYear = 10 * CENT; else if (primeNodeRate == 20) nRewardCoinYear = 20 * CENT; else if (primeNodeRate == 100) nRewardCoinYear = 100 * CENT; else if (primeNodeRate == 350) nRewardCoinYear = 350 * CENT; nSubsidy = nCoinAge * nRewardCoinYear * 33 / (365 * 33 + 8); if (fDebug && GetBoolArg("-printcreation")) printf("GetProofOfStakeReward(): primeNodeRate=%d create=%s nCoinAge=%"PRI64d"\n", primeNodeRate, FormatMoney(nSubsidy).c_str(), nCoinAge); return nSubsidy; 
Paycoin started off as a coin with a 13,000,000 coin market cap, with two stages. A Proof of Work and Proof of Share. Check this out: https://twitter.com/gawceo/status/532173907718332417 - Garza claims that he "mined" for the 12,000,000 coins he gained, although block one was programmed to give him that much... hah!
Credits to https://gist.github.com/jyap808/3f99de084df18ce325a7 for this;
Block 1. 12 million premine.
343,196 XPY mined during Proof of Work period.
343,196 - 56,889 = 286,307 XPY not mined by GAW Miners
12,343,196 XPY coins mined Total at the end of Proof of Work including pre-mine.
100 - (343196.0 / 12343196 * 100) = 97.22% Premined at the end of Proof of Work
It also seems like Garza stole the logo for Paycoin from https://www.gopago.com/. If you compare it with what's on https://paybase.com/ they're identical.
-Current and Recent Events
It's also known that there was a massive security/data breech during the Paybase launch, which allowed users to see other's balances and personal information https://coinfire.cf/2014/12/31/massive-security-breach-at-paybase/ which is being blamed on a "Cloudflare Caching Issue," however, that excuse makes very little sense.
Currently, people are having trouble withdrawing their Paycoins from Paybase, which GAW is blaming on Authy. Authy's services are functioning fine for all other services, which leads us to believe that it isn't Authy's fault.
When Hashtakers were sold, they would've only been really profitable at the $20 per Paycoin mark. With the current price people are losing money on their investment.
Note: This is somewhat unfinished and I'd like to hear feedback on what I should add and revise.

The Regulatory/Legal Environment

Hello! My name is Daria Volkova and I am the Head of Platinum Legal Department. Our team believes that these are exciting times for the crypto market. We supported more than 100 clients, created and promoted their STO and ICO campaigns, got from an idea to funding in a matter of 2.5 months! See the full list of our services: Platinum.fund We are more than proud to present our education project. The UBAI can help you to learn specifics about cryptocurrencies and blockchain technologies. Learn all about ICO avenues and opportunities, plug into the world of trading cryptocurrency markets, become an expert in scam projects, promoting ICOs and STOs, launching your own campaigns and many more! What are the different cryptocurrency regulations in major countries? Find the answer after reading this article.
Cryptocurrency Regulations across Major Countries
Cryptocurrency and the blockchain industry may seem sufficiently exciting and attractive to you now. After all, you are taking the time and effort to study this course. You may be planning to work in cryptocurrency and the blockchain industry. Of course, we want to encourage you and help you proceed toward your goal. But it is also important you understand the regulations guiding the blockchain industry to help keep yourself out of trouble.
This year, in particular, seems to be the year in which a lot of countries are looking to finally coalesce the regulations relating to the blockchain industry into a workable legal framework. Some countries are more accommodating to cryptocurrency and blockchain technological innovations while others are still more cautious. We will examine how each major country is forming their own regulatory framework for the blockchain industry.
Canada
Cryptocurrencies are not considered legal tender in Canada. This was clearly expressed by the country’s Financial Consumer Agency (FCA). Canada, like the US, has yet to clearly define or legislate a framework surrounding cryptocurrencies. But Canada still appears to be among the most transparent of countries for the nation’s interpretation and enforcement of the law surrounding cryptocurrencies (aside from Switzerland). For the time being, Canada has clearly stated its reluctance to adopt cryptocurrency as a legal tender, due to its high volatility. “ “The United States of America (USA)
There are certain laws regarding transactions in virtual currency in the US today but there is still no comprehensive legal framework. The Commodity Futures Trading Commission currently regulates virtual currencies as commodities. The CFTC is the first US regulator to allow for public cryptocurrency trading. The Securities and Exchange Commission requires registration of any virtual currency traded in the US if it is classified as a security (e.g. by the Howey test).
The regulatory authorities have not yet formulated or offered a coherent framework for regulations regarding cryptocurrencies. Typical of most legislators and regulatory agencies in the US, the Securities and Exchange Commission (SEC) has intensified its focus on the pressing need for comprehensive regulation. And it seems everyone is waiting for the right catalyst to coalesce into a usable set of legal guidelines that can protect the investing public and also allow for blockchain and cryptocurrency innovation as well.
If cryptocurrency becomes a form of legal tender in the US, there will likely be stringent laws on its use. However, if cryptocurrency is treated like a security, cryptocurrencies would be regulated under securities law as interpreted by the SEC. Present securities laws place a large number of limitations on who is able to buy securities, how they are traded, and how to ensure transparency in the flow of information relevant to investors. Also note that non-US investors may experience their own difficulties getting a license to trade cryptocurrencies in the country. “ “Japan
Japan has always been one of the most positive and forward-thinking nations regarding cryptocurrencies and the blockchain. Of course, they were cautious at first, and they knew no more than anyone else in government, which means they literally knew nothing. But they took time to research, learn, and develop an approach to regulate the industry without killing it. The official policy is clear: Protect the public interest, but also encourage the growth of the industry with a legal framework that allows for innovation in blockchain and cryptocurrencies.
China
The situation in China is a sad one. The country has been taking increasingly strict actions to discourage and outlaw any activity related to the blockchain industry. China has banned ICOs, frozen all accounts associated with cryptocurrency, stopped bitcoin miners and even ordered a nationwide ban on all forms of cryptocurrency trading.
China has the strictest laws against cryptocurrency. Yet, despite that fact, as of 2017, 50% of the world’s mining population was from China! If you are involved with the cryptocurrency industry it is strongly advised to stay away from China, and avoid transactions with Chinese business because of the unpredictable and negative legal framework.
“ “The United Kingdom & European Union
Brexit is scheduled to take place in March 2019, yet the UK and the EU still remain united in their regulatory attitude toward cryptocurrencies. There are also reports that the UK and EU are planning to end anonymity for cryptocurrency traders.
The UK and EU are both trying to control all the scams and frauds. They are working with cryptocurrency platforms to stop or at least report all suspicious transactions. This adds a degree of regulatory burden on the exchanges as well as increasing the associated compliance costs. Cryptocurrencies are extremely volatile. They are a high-risk investment. Governments across Europe are greatly concerned about the possibility of both retail and sophisticated investors losing a lot of money.
This has led to a situation similar to that in the US. The regulatory authorities have not yet formulated or offered a coherent framework for regulations regarding cryptocurrencies. There is an intense focus on the pressing need for comprehensive regulation. And everyone is waiting for the right catalyst to coalesce into a usable set of legal guidelines that can protect the investing public and allow for blockchain and cryptocurrency innovation as well. We certainly hope for intelligent and effective legislation from all the major countries. “ “Accommodating & Unaccommodating Countries
Below is a list of countries we have not specifically covered, but they have each taken an active position on a regulatory framework for cryptocurrencies. The following countries are either supportive or at least neutral toward cryptocurrencies:
-Switzerland. -Australia. -Nigeria. -Ghana. -South Africa. -Singapore.
Countries with the most stringent and negative cryptocurrency regulation:
-Venezuela. -South Korea. -India. -Russia.
Did you know?
It is not uncommon to see Bitcoin and other cryptocurrency ATMs throughout Japan.
Exchange robberies and hacks like MtGox, and the recent loss of $530 million NEM coins have led to serious debate in the Japanese government. The industry needs to provide a secure and manageable solution to these problems. Voluntary self-regulation and close cooperation with regulatory authorities is the most favored solution. It seems the regulators are working hard behind the scenes right now leading the industry in the desired direction in typical Japanese fashion. “ “Blockchain Industry Regulations in the USA
Based on the information received from the Columbia Science and Technology Law Review, there was a variety of responses from different government bodies about blockchain regulations. The regulators responses ranged from indifference to suspicion, and to positive expectation and excitement.
The US government has tremendous constitutional power to regulate business and industry, including of course the blockchain industry if it so desires. But basically, the federal government has been relatively indifferent and has even refused to speak on blockchain regulations despite the interest of various federal agencies. As of 2017, eight states in the US were working on bills promoting the use of cryptocurrency and blockchain technologies. It is even reported that a few states have actually begun the final steps before voting and passing legislation into law.
On April 3, 2018 Arizona introduced a law allowing corporations to hold and share data on the blockchain. The governor, Doug Ducey, put forward the legislation after the state began accepting signatures and smart contracts recorded on the blockchain as legally valid documentation. In 2017, Delaware was the first state to pass legislation allowing for shares of stocks to be legally traded on the blockchain.
Other notable developments have occurred in the US at the state or local level. Vermont makes use of blockchain as evidence in trials. Chicago uses blockchain to maintain real estate records. New York is currently evaluating four bills for the application of data storage on the blockchain. “ ” Blockchain Regulations in Europe
The entire European Union has approached blockchain with a positive and welcoming attitude. The EU has taken the position that they want to actively encourage innovation. This philosophy could support the development of cryptocurrencies in two ways:
-Encouraging the exploration of uses testing the impact and effect of the laws in a way that allows for a more finely-tuned and sophisticated understanding for all parties involved.
-Giving entrepreneurs the confidence that their target markets will be more trusting of their solution since they are operating with the explicit legal support of the state.
This approach, along with the EU’s scope as the regulator of 28 different countries, will encourage growth across the entire crypto ecosystem, and may end up transforming Europe into one of the most desirable destinations for blockchain development. Entrepreneurs are likely to move to the EU bloc to access the rich vein of available talent, as well as the positive and supportive laws.
The EU has actually disclosed through its executive arm that it is working on the use of blockchain for distributed ledger based projects. EU officials have constantly stated they are looking for ways to support more innovation with distributed ledger technology. The European Commission said it was “”actively monitoring Blockchain and DLT developments”” and has work in progress to explore “”DLT benefits and challenges as well as fields for application in financial services””.
The official press release stated that the commission clearly wants to “”pilot projects to foster decentralized innovation ecosystems and help reshape interactions between consumers, producers, creators and among citizens, businesses and administrations to the end benefit of society””. “ “Blockchain Regulations in Europe §2
Switzerland has gradually become the favored hub for cryptocurrency and blockchain development in Europe. This position has been enhanced through a Swiss non-profit blockchain and cryptographic technology ecosystem known as the Crypto Valley Association.
The Crypto Valley Association has begun working on the development of an ICO Code of Conduct to take advantage of the ban imposed by China on token crowd sales. They are hoping to capture the Chinese and Asian entrepreneurs searching for a new home.
Other countries are not as accepting of this new DLT technology and have even gone as far as classifying it as illegal and immoral behavior. There have been hyperbolic concerns most notably from China that cryptocurrencies will destabilize world financial markets.
There are various pilot projects and efforts to prove the benefits of cryptocurrencies and the blockchain industry currently being tested all across Europe. Yet even now they are barely scratching the surface of the full potential of the blockchain.
Country-by-Country Cryptocurrency Adoption
Citizens of countries all over the world have varying attitudes about cryptocurrency. These attitudes and sentiments can be very significant to the future adoption of cryptocurrencies because politicians and regulators tend to act in consideration of the collective opinion of the public. Some countries were more accommodating at first but then became stricter, despite positive public interest, basically saying they are still not sure about the possible consequences and benefits of the technology. “ “Country-by-Country Cryptocurrency Adoption
Estonia
Surprisingly enough this small Baltic nation has gained a reputation for being quick to accept technological innovation. Estonia has a tech-friendly government eager to accommodate the innovative use of cryptocurrency in fields ranging from blockchain technology for healthcare and banking services; and even granting citizens the right to become what is known as “e-Residents”.
As e-Residents, Estonian citizens and businesses are provided with digital business authentication. It is also one of the first countries to employ the use of a blockchain-based e-voting service that enabled people to become shareholders of NASDAQ’s Tallinn Stock Exchange.
This fascinating and highly innovative country is now host to a number of Bitcoin ATMs and startups, like Paxful. They are cryptocurrency friendly, and cryptocurrency user friendly as well. Estonia also has highest internet penetration rates in the world.
Estonia may be a fine place to consider basing your ICO due to the friendly legal and regulatory environment.
This and a lot more you can learn on our website: www.ubai.co! “ “Country-by-Country Cryptocurrency Adoption
The United States of America
The USA is the world’s dominant superpower, and it should come as no surprise that it has the highest number of cryptocurrency users in the world. It also has the highest bitcoin trading volume and the highest number of bitcoin ATMs.
Powered by Silicon Valley, which is home to a lot of cryptocurrency and blockchain startups, the US stands at the forefront of all things relating to cryptocurrency worldwide. Many other nations are planning to follow the US lead concerning cryptocurrency regulations. This means the USA will serve as the testing ground for cryptocurrency and crypto-regulation in the years to come. This is likely where the future regulatory framework will take shape.
Bitcoin in particular has shown massive growth in the US. This can only be interpreted as a strong tailwind for a positive regulatory environment because the population at large supports blockchain technology.
For the moment, due to regulatory paralysis and the resultant legal vacuum, ICOs are strongly advised against raising funds or basing operations in the US. The SEC has been particularly strict in its enforcement of securities and investment law which require an ICO to do an oppressive amount of compliance work. “ “Country-by-Country Cryptocurrency Adoption
Denmark
When it comes to technological advancements and the standard of living of its citizens, Denmark is among the world leaders. It is considered one of the most developed countries in the world. It is also at the forefront of countries looking to reduce the use of cash money and advance to the use of 100% digital currency. As such, sentiment among the general public and political sphere actively supports the adoption of cryptocurrencies as a means of payment. The only question left is which particular cryptocurrency system to adopt. It is still unclear whether bitcoin is the one, or BTC will mainly just be accepted as a means of exchange. There are also discussions in Denmark about when to redesign its national financial system; this would be a “world first”, and a radical leap forward for cryptocurrencies.
Another fascinating thing is that the Danish Central Bank has declared BTC as a non-currency; meaning its use is not subject to the country’s currency regulations. Some of the top bitcoin startups and exchanges such as CCDEK have their foundations in Denmark.
With its open market and encouraging regulatory framework, Denmark might very well rival Switzerland in Western Europe for the position of the continent’s preeminent ICO and blockchain industry hub. “ “Country-by-Country Cryptocurrency Adoption
Sweden
Sweden is quite similar to Denmark, for its social and demographic climate, and also for the government’s desire to eliminate cash. The Swedish Riksbank recently introduced negative interest rates. This can cause a spike in the demand for coins in the near future as citizens look for the best way to preserve their wealth. Negative interest rates like we have seen in Europe and Japan also, actively corrode savers’ wealth because people are actually paying a percentage of their savings to the central bank to hold their cash, in addition to losing out to inflation at the same time.
Sweden has taken the boldest step yet in all of continental Europe to legalize cryptocurrency. The country legalized the use of BTC and other cryptocurrencies as a means of payment by official public declaration. It is however expected that exchanges should file for a license in accordance with AML/CTF and KYC regulations.
Sweden is also home to a number of cryptocurrency startups such as the Safello Bitcoin exchange, and Stockholm-based KnCMiner. The gradually increasing trading volume of cryptocurrency has been a good indicator of the country’s appreciating demand for cryptocurrencies. “ “Country-by-Country Cryptocurrency Adoption
The Netherlands
The Netherlands is quite fascinating in its own right. How can a country not be referred to as Bitcoin-friendly when it can boast about having its own “Bitcoin City”? There are over 100 merchants that sell goods that can be purchased with cryptocurrency in Bitcoin City.
There are no regulations restricting the use of BTC in the Netherlands under the Act on Financial Supervision of the Netherlands. This explains why a lot of startups, BTC ATMs, and even a Bitcoin Embassy can be found in the heart of Amsterdam (the capital of Netherlands).
The friendly climate for cryptocurrency has led to a lot of very active bitcoin communities across the nation hosting regular meetups and other events. The country’s banking sector has been looking to incorporate BTC and blockchain to reduce costs and improve banking technology. The Netherlands is also a popular location for many important bitcoin conferences and bitcoin companies such as BitPay.
The Netherlands is increasingly becoming a prominent place for ICOs and blockchain related businesses to base their operations. “ “Country-by-Country Cryptocurrency Adoption
Finland
Well-known as the home of Nokia, Finland has constantly been at the forefront of technological innovation, just like its other Scandinavian neighbors. The Finnish Central Board of Taxes (CBT) has even gone as far as classifying bitcoin as a financial service, exempting it and cryptocurrency purchases from the VAT. What more could be better for Bitcoin?
Finland also boasts a significant number of BTC ATMs despite its small population. The capital of Helsinki alone is reported to have 10 ATMs for BTC. The country is also home to top exchanges such as FinCCX and Bittiraha.fi. As of January 2016, the most expensive bitcoin sale took place in Finland. It involved the sale of a Tesla Model S worth over €140,000 at Auto-Outlet Helsinki Oy.
Canada
Canada is home to a variety of bitcoin startups and ATMs. It is considered to be more favorable toward cryptocurrencies than the USA. The country has two cities on its eastern and western coasts, Toronto and Vancouver, that are recognized as “Bitcoin hubs”.
Canada has a vibrant cryptocurrency community and is home to startups such as Decentral, the Vanbex Group and a large number of merchants who accept cryptocurrencies as payment. Vancouver is known to have over 20 ATMs while Toronto is well-known for holding large cryptocurrency conferences.
There has been constant growth in cryptocurrency trading volume in the country. Canada might be the best location in North America to base an ICO or operate a blockchain business due to its supportive regulatory environment and a rich ecosystem for cryptocurrency, with human talent, ATMs and other tools, etc. “ “Country-by-Country Cryptocurrency Adoption
United Kingdom
The UK is one of the absolute top financial hubs in the world. It is also a center of innovation. There are a large number of bitcoin and blockchain related startups, BTMs and active communities. All of the previously listed crypto-friendly features make the UK a very desirable environment for bitcoin. The UK has identified the inevitable need for a new payment solution and is gradually bracing itself for a widespread adoption of cryptocurrency in the future. There are even a few local pubs that accept BTC as a means of payment.
It is also interesting to note that the Bank of England has been closely monitoring bitcoin technology and has requested ideas from citizens on the improvement of its monetary system. Bitcoin is presently seen as “private money” where VAT is imposed from suppliers of goods and services that accept cryptocurrency as payment. Profits and losses incurred from cryptocurrency trading are also subject to capital gains tax, just as in the US.
In the UK, it has become increasingly clear that BTC can be part of a bigger story, and the trading volume indicates steady growth. There are not clear laws against cryptocurrencies at the present time. But the lack of regulatory momentum suggests we may see more positive developments soon. One thing to keep in mind, while the Brexit is still in progress, the British government may be more likely to legislate on non-core issues. “ “Country-by-Country Cryptocurrency Adoption
Australia
The major banks in Australia have been quite hostile toward bitcoin, but at least the country has removed the burden of “double taxation” on cryptocurrency. This was good news to the local business community because blockchain startups had begun to leave the country as a direct result of unfavorable taxation and closure of bank accounts.
The use of BTC still remains unregulated, there is no law or regulation restricting the use of cryptocurrencies by Australian citizens. Cryptocurrencies are regarded as a form of property in Australia, and purchases with BTC, for example, are referred to as “barter”.
The Australian Securities Exchange (ASX), you will remember, is transitioning its CHESS verification system to a blockchain solution that should go live at the beginning of 2019. Cryptocurrencies in Australia are seen a lot like they are in the US. Topics like the imposition of capital gains tax, concern about securities law, the legal debate about using cryptocurrency as payment for goods and services, etc., are all problematic for regulators. While the general population is quite comfortable and supportive of cryptocurrencies and blockchain solutions, at the present it is not a high priority for the government to legislate or regulate. “ “Taxation and Cryptocurrency
Tax is of course one of the most important factors in financial matters on both a personal and corporate level. Taxes greatly influence investment decisions and returns, regardless of industry or size. It is one of the first things every individual or group considers before investing. Notably, in Australia and the USA, cryptocurrency gains are treated as capital gains and taxed at up to 50% of the return.
Some countries have low cryptocurrency taxes specifically to encourage the blockchain industry. By offering a more competitive tax rate, countries are implicitly supporting cryptocurrency and actively trying to offer a better return profile than other countries. We will discuss the different taxation regimes in a wide range of countries so you can ascertain the financial advantages and disadvantages of a variety of locations.
Belarus
Belarus charges 0% in taxation until 2023. That exemption is specifically for cryptocurrency exchanges and transactions. This has been done to help Belarus build a special economic zone, referred to as ‘HTP Belarus’. Their goal is to have an economic zone strong enough to compete with the likes of Silicon Valley.
The government of Belarus has also declared smart contracts as legal documents. Anyone looking to set up a blockchain company or a cryptocurrency startup should seriously consider Belarus. It has a supportive regulatory and legal environment which actively encourages the blockchain industry and does not impose punitive taxes upon those inside the industry.
“ “Taxation and Cryptocurrency
Portugal
Any and all personal income received from cryptocurrency transactions is tax-free in Portugal at the present moment. Income from cryptocurrency trading is categorized as something legally different from traditional income or capital gains.
The Portuguese government stated clearly that any kind of sale of cryptocurrency does not fall under capital income or capital gain. If an individual is however found to be carrying out professional activity, or any business activity related to cryptocurrencies, that is a different matter and such income will be subject to taxation.
From a personal perspective, Portugal is one of the leading countries where an individual can carry out their cryptocurrency transactions and enjoy a decent standard of living in the same country too. However, for ICO and Blockchain businesses it is not recommended to base your operations in Portugal.
China
China is famous the world over for being home to some of the largest cryptocurrency mines and many active cryptocurrency investors; yet at the same time China makes it illegal to conduct any cryptocurrency related business or investment.
But China still has an especially attractive environment for investors. Hong Kong runs on a policy of zero VAT or capital gains tax so it is easy to recommend you base your business there. Hong Kong also stands out as a major financial hub in the heart of Asia. “ “Taxation and Cryptocurrency
Netherlands
Actually, Netherlands was the first country to make use of a non-zero tax rate policy for cryptocurrencies. So, it may seem reasonable to expect a discouraging tax situation. But the fact is, Netherland’s tax policy is rather advantageous for cryptocurrency. They have a very simple, low-tax regime.
Cryptocurrency assets need to be declared with the total assets owned by an individual at the beginning of the year to assess their value. Cryptocurrency gains will be taxed at the highest tax bracket for capital income of just around 5%. The Netherlands is strongly recommended as a good country to work and live in, from both a personal and corporate perspective.
Germany
Germany is the economic center of the EU. This makes it a great place to start a cryptocurrency or blockchain company. Financial technology has been thriving there for more than ten years, and Germany has favorable cryptocurrency laws too.
Bitcoin and cryptocurrency assets have a 0% tax when used in making payments due to no VAT levied for making payments with BTC, because there is no “value added” through cryptocurrency as a fiscal product.
Germany offers a moderately compelling case for both blockchain business and individuals. While the tax rate on income at the company level is not competitive, the ability to pay for services in crypto as well as hold cryptocurrency assets and sell them at zero percent taxation rate is compelling. “ “Where to Base Your ICO
Let’s talk about the countries that are most accommodating with regard ICOs. Start-up ICO companies, like any company, essentially require three key principles for operation. The first is a sound legal and regulatory framework wherein the rule of law is preserved and business encouraged. The second is the ability to hire or acquire talented individuals to work at the firm. The third and final is the tax system and access to associated financial systems in order to allow the enterprise to succeed.
Estonia
This country is, perhaps surprisingly, widely referred to as the most digital society in the world. Estonians are known to be pathfinders deeply involved in setting up an efficient, secure, and transparent internet ecosystem.
The country ranks first when it comes to the number of ICOs per inhabitant. It has an incredibly supportive tax regime, actually among the most competitive in the world, as well as a deep pool of talent across all areas of the digital spectrum. Estonia offers possibly the most supportive and friendly regulatory and legal framework in the world for an ICO. This, in combination with a zero percent tax rate at both a personal and corporate level, combine to make Estonia one of the single most appealing locations from which you can launch and operate your ICO. “ “Where to Base Your ICO
Singapore
Singapore is another important regional hub in Asia for its strong rule of law as well as low taxation. The country offers one of the highest standards of living in the world. It is centrally located in the heart of Asia, so it easy to travel and recruit talent from surrounding countries. At the present there are not any specific regulations targeting the blockchain industry, but it is one of the world’s largest countries by funds raised for ICOs. It has a competitive tax regime in combination with strict AML and KYC. All of these factors make Singapore Asia’s leading location to launch and base an ICO.
The regulatory situation around the world may seem rather complicated. That is because it is. Laws and regulations are changing rapidly all over the world. And the regulatory framework is the most significant point of concern for a startup ICO. You should carefully study not only the current regulations surrounding your particular venture and how its tokenomics affects its classification, but you also need a reasonable sense of where the country is likely to be six months or a year later. Ideally you would base your ICO in a country that is supportive now, and all timeframes into the future with a competitive and legally sound tax system.
Where to Base Your ICO
Slovenia
Slovenia has recently transformed itself into the leading destination for blockchain technology in Europe. The government of Slovenia has placed a strong emphasis on the study of blockchain technology in public administration, and there has been an amazing success rate for ICOs in Slovenia. While the Slovenian government is a leader in terms of adopting cryptocurrencies, its rate of taxation is still considered quite high at 19%, even though that is still lower than other European countries. ICOs are considered to be normal business activities where you are taxed based on the funds received from an ICO less the expenses of doing business.
Switzerland
Switzerland is trying to remain relevant for the blockchain industry and for ICOs. The Swiss finance ministry is actively trying to attract investors to the country. Switzerland is considered a very important crypto location due to fact it was home to four of the largest ICOs in the world. The country is also very attractive to investors because of its friendly regulations and digital expertise. The taxation and regulatory environment is extremely secure and positive towards the cryptocurrency and blockchain industry in general.

Cocos-BCX:The decentralized gaming application & crypto assets creation platform

Cocos-BCX:The decentralized gaming application & crypto assets creation platform

I. Project Overview

Cocos-BCX is a platform used for the development, operation, management and transfer of decentralized applications and in-application assets on the blockchain ecosystem. The platform mainly includes three function modules:
(1)The application development framework that supports multiple operating systems and various blockchain environments.
(2)Completely scripted, componentized and data-driven application development tools;
(3)An improved blockchain system, which is oriented to high performance applications and based on graphene technology framework, and its related functional components.
Cocos-BCX can allow developers to perform programming, debugging, and publishing of decentralized applications oriented to the blockchain environment, and hybrid architecture applications. Meanwhile, the platform integrates the distributed user account system, wallet and digital asset circulation platform based on the blockchain, which can realize the permanent saving and cross-chain use of in-application assets.

II. Project evaluation

(一) Market analysis

1. Market conditions | 8 points

The organizing pattern of productivity dominated by governments in some areas or industrial domains is apt to change in the context of bottlenecks existing for global scientific and technological progress, rising resource consumption, an aging population, and intensified geopolitical conflicts. In particular, in 2008, when Nakamot published his thesis "Bitcoin: A Peer-to-Peer Electronic Cash System", discussions on blockchain and digital currency have gradually extended from technological aspects to economic, social and political, and other fields. The general public have begun to pay close attention to the impact of blockchain on social development as well as the role of digital currency in the world economy. Based on the decentralized characteristics of the blockchain and the vibrant vitality of the digital economy, the general public has enough confidence to predict that the decentralized "digital assets" will be a sweeping trend in the future, and will derive new business models and social values.
At the same time, in the development process of decentralized applications of different types, the game industry enjoys unique development advantages, because the game's production mode is the most sophisticated, enjoys the highest degree in terms of commercialization, and is one of the scenarios with the most profound foundation in terms of developers and users.
u Analysis: The game field has a huge room for development, which is highly consistent with the characteristics of the blockchain, and accords with the future development tendency of the digital economy.
The digital asset economy model carried by the project through the blockchain technology will assetize the content produced by the developer, enable the developer to continue reaping benefits during the use, management and transfer of his assets, and provide him with a convenient, decentralized game distribution channel; meanwhile, it helps players to transform the data formed by time and energy as well as the props they obtain as a result of their consumption into the assets that can be safely stored and circulated, offering players the right to manage and commercialize them.

2. Competition | 8 points

Since the last century till now, owing to the sustained efforts and promotion by a variety of IT technology game enterprises, the national and even global online game market is developing by leaps and bounds. If there is no systematic risks, such as policy regulation, vicious incidents and other factors, there will be no smooth and endless development momentum unless something unexpected happens. However, an objective analysis reveals that the current online game market is still dominated by IT technology companies, and even in a controlled and monopolized development, which, of course, also brings substantial profits, such as Tencent, Blizzard Tech.
u Analysis: It can be predicted that the Cocos-BCX project will hardly have any direct competitors in the strict sense for the time being, but will encounter a marginal pressure competitive environment from two dimensions. In summary, the classical IT game companies at home and abroad are massive in size and have obvious capital advantages. However, the Cocos-BCX project has an advanced philosophy and cutting edge technology, and thereby enjoys first-mover advantages for a breakthrough; The blockchain game project of the same business is currently marked by wide participation and generic applicability. But in comparison, the Cocos-BCX game industry has such advantages as a salient background, special project orientation and sophisticated development in technical modules, and therefore has greater development potential.

(二) Token Status

1. Token situation | 6 points

(1) Basic situation of Token
Token name: COCOS
Total tokens in circulation: 100 billion
Consensus mechanism: DPOS
(2) Token usage and allocation
Part I 82%: Cocos-BCX is used for the platform community construction in various ways, including but not limited to the witness' block reward, incentives for platform ecological developers, global community construction, marketing and promotion, industry alliances, eco-investment, research, financial and legal compliance. The use of this part of Cocos-BCX includes swapping by means of the consensus work contributions, free gifts, gifts in exchange for service, and gifts in exchange for other tokens, etc.
Part II, 18%: Cocos-BCX is intended as incentives for the sponsoring team of the project. The incentive part will set up a locking mechanism, which will be issued and unlocked one-third at the end of each year after Token generation, and the issuance will be completed within three years.

https://preview.redd.it/sahtuohmtb821.jpg?width=684&format=pjpg&auto=webp&s=324cbde0e5911f219649d8a64470dc3d70ecdb7f
u Analysis: The use of Token is mainly divided into two parts, among which, 82% is used for project development and construction. The remaining 18%, which has a locked position mechanism, is intended for team incentive and construction. The use design is rather rational, but the team part is slightly higher. Given that the industry is in the initial stage of development, it is of great importance to seize the first opportunity and acquire early traffic users. It is suggested that the proportion of Token used by the team be reduced slightly, which is more conducive to the long-term development of the project. It should be noted that the original holding distribution of Token has not been queried via the official channel, while this link for the conventional blockchain project are basically disclosed. Meanwhile, from the standpoint of ordinary investors, Token’s original holding ratio is also one of the important parameters for its investment.

2. Ecological cycle | 8 points

(1)The Token (COCOS) positioning of the platform: circulation media and governance proof in eco-economic activities
COCOS not only serves as a value exchange carrier and community participation proof for Cocox-BCX, but its orientation as a basic pricing Token is likely to play a critical role in the digital asset ecosystem. With the continuous development of the industry, a large quantity of decentralized digital assets will exist in multiple blockchain ecosystems according to different standards in the future, and the value existing in asset pricing media transcending the chain ecology will be infinitely magnified.
, which is specifically manifested in that developers and users can evaluate, compare, trade and manage digital assets of different chain ecosystems, worldview content, and technical standards based on COCOS. Meanwhile, as a primary and basic pricing medium, COCOS is positioned to become the necessary conditions for the blockchain industry to develop and trade financial products and derivatives of digital assets in the future.
(2)Basic use model of Token (COCOS)
Ø Value exchange medium within the platform ecosystem;
Ø Entrusted consensus equity share representative of the Cocos-BCX public blockchain;
Ø The reference and basis for the measurement of the participation in and contribution to the platform community.
(3)How to obtain Token (COCOS)
Ø Value creation: It includes the contribution of the behavior of creating digital assets, that is, developing games, making props, etc.
Ø Platform contribution reward: Users who contribute to the Cocos-BCX community is entitled to COCOS;
Ø Market transaction: Selling the prop assets obtained in the game to get COCOS;
Ø Behavioral incentives: Various effective behaviors within the Cocos-BCX platform, community and platform games will be converted into COCOS
according to a certain contribution degree.
u Analysis: The use model, scenario application, acquisition method, market orientation, etc. for the Token ecosystem design are all well deliberated, to be verified by the market.
The ecosystem design of the Token project not only takes the macroscopic use model and scenario application, but also gives a detailed description of the acquisition method. Another point that must be pointed out is that it has a clear market orientation and future prospect as soon as the design begins, therefore, in general the Token ecosystem design is well-considered and far-sighted. However, for the volatile blockchain market, the crux depends on whether the ecological design philosophy can keep pace with the times, which is very essential. In a word, in the face of massive uncertainties, it needs to be finally verified by the market.

(四) Tech Analysis

1. Tech highlights | 9 points

(1) Smart contract system which can be updated iteratively: The smart contract system, represented by Ethereum, is not subject to modification once its definition is published, making it difficult to meet the volatile demands of market. Therefore, an iterative smart contract system is designed to address this pain spot.
(2) Prop circulation platform: Unlike conventional game transaction platform, Cocos-BCX's decentralized digital asset circulation platform does not have intermediary agencies. Players can complete the transfer and purchase of non-homogeneous assets, including "game gold coins" and prop assets acquired in the game on the prop circulation platform. In the whole process of transfer, the platform will adopt smart contract for automatic matching to help users complete the transfer process more efficiently.
(3) Game interactive operation environment:
Based on the judgment of the operation environment characteristics of blockchain games in the future, Cocos-BCX has designed a set of integrated operation environment that accommodates various types of APPs, as well as the supporting interoperability interface. Combined with COCOS Creator, it simplifies the process of docking game programs and blockchain, making intra-chain interaction transparent to developers, and allowing conventional game developers to develop or migrate blockchain game without a threshold.
(4) Mapping gateway that supports multi-chain and asset riveting:
Cocos-BCX provides a set of mapping gateways used for the automatic mapping of game gold coins and props. Under the unified value measurement system, it realizes the smooth transition of different in-chain game content and different platform content. The content that can be used for mapping includes game gold coins, game equipment data, etc.
(5) Transaction authentication mechanism that prevents BP/developers from cheating:
BP, as the core of transaction processing and communication of the whole network, can know the processing result of the latest transaction prior to general nodes. Therefore, BP enjoys a priority for information with timeliness or confidentiality
, as compared with general nodes, so it has a cheating potential in terms of
information acquisition. To address the drawbacks of this technical link, five modular confrontation mechanisms has been specially designed to hold the likelihood of BP/developer cheating at bay.
(6) Economies Principle Design of Cocos-BCX:
The Cocos-BCX platform carries the game assets value created by developers by providing a complete set of functional components including the underlying public blockchain, digital property management, and exchanges. Its technology and governance structure design, based on the graphene standard, has the economic attributes corresponding to the DPoS consensus mechanism.
u Analysis: There are a multiplicity of technical highlights in that the overall technology construction shows characteristics such as rigid logic and prominent modularity, and various technical solutions and mechanisms with a strong pertinence have been put forward.
Based on the market pain spots of the game industry, and combined with the development opportunities of blockchain technology, the Cocos-BCX project puts forward a vision system to create consistence between the content producer and consumer in the digital world. In view of the initial intention of the project and the relatively profound background of the game industry, the overall technical structure design of the project is highly targeted and has a strong logic, which can be described as closely connected with each other. Based on the large technical framework system, each technical link and organization also has a strong sense of target and logical gene, and on this basis, many modular and modified technical programs or mechanisms have been proposed. However, it is worth noting that the synergy of a series of highlight technologies remains to be verified and examined. Meanwhile, attention should also be paid to the practicability and rationality.

2. Impossible Triangle | 7 points

(1) Decentralization
Ø Low fork risk: Cocos-BCX uses the DPoS consensus mechanism, which does not require miners to use mining machines for mining, and thereby it can effectively avoid the impact of centralized computing on the entire basechain, which in turn reduces a low fork risk. Under the DPoS mechanism, if a witness wants to fork by voting, it is necessary to guarantee that over one third of the witnesses violate this mechanism at the same time.
Ø Improved DPOS consensus mechanism: The consensus layer of the Cocos-BCX test chain adopts the DPoS consensus algorithm. The advantage characteristics of the improved edition DPOS are as follows: all active witnesses have the same block predefined probability as the witnesses' predefined algorithm in the DPoS consensus algorithm, which ensures that the block probability of all witnesses is consistent with the block reward.
Ø Lightweight node: In Cocos-BCX design, lightweight node is essentially an environment with chain interoperability. Unlike the whole node, the lightweight node does not require to synchronize the whole network data. Instead, it needs the contract information and environment data required for synchronous running. This design can greatly reduce the data volume and synchronization time required for node synchronization, enabling the in-chain game terminal software to have a capacity which is actually used and a plausible time cost.
(2) Security
Ø Player autonomy and asset security: Because of the open and transparent characteristics of the blockchain network, the digital asset information obtained by players in the game can be viewed through the blockchain.
Ø Guarantee by modern cryptography: Modern cryptography is a technology based on mathematics. Currently, it has been widely used in many industries in the Internet domain. Common symmetric encryption technologies include AES encryption used for WiFi, and asymmetric encryption algorithms (public and private key cryptography) RSA, ECC, etc., among which, ECC (Elliptic Curves Cryptography) is an encryption algorithm commonly used in the blockchain field.
Ø A transaction verification mechanism that prevents BP/developers from cheating: BP enjoys a priority compared with general nodes, so it has the probability to cheat in terms of information acquisition. Therefore, the BCX program has designed a set of transaction execution, messaging, and operating mechanisms to address the possible links that allow cheating by BP and developers.
Ø Iterative updated smart contract system: It can provide logical updating and loophole repair for the in-chain game smart contract, thus ensuring the security and timeliness of the smart contract.
(3) Expandability:
Ø Strong expandability of the top-level design of the project
The expandability of Cocos-BCX is powerful, which is specifically shown in a decentralized game production and an overall solution to the game economy operation established by means of the game engine, development environment and Cocos-BCX game chain.

https://preview.redd.it/xm5n7esrtb821.jpg?width=1207&format=pjpg&auto=webp&s=c3daa5d913560c0e8143c0635374596566bdbfc9
A business ecosystem is constructed based on the above overall solution, with the purpose of connecting the global game ecosystem. The main ecological links include developers, users, creative content, key ecological links and blockchain system, etc.

https://preview.redd.it/h4ssn41ttb821.jpg?width=1276&format=pjpg&auto=webp&s=ca6244d17b9745ce41b5be235f75a39f8a8af051
Ø Expanded design of specific technologies and mechanisms
  1. Multi-platform game integration running environment: This platform is mainly characterized by four features, consistent and perfect chain interoperability interface, downward transparent accepting mode, encapsulated atomic operation and multi-platform compatibility.
  2. Interactive interface of blockchain:
Cocos-BCX provides a chain-interactive development environment so that developers can easily interact with the chain through this set of environment. Meanwhile, its blockchain interactive development environment provides development components compatible with multiple working platforms, including SDK for the Android and iOS system, javascript libraries for front-terminal web applications, and python and PHP libraries for back-terminal applications.
u Analysis: The expandability of the project's "impossible triangle" shows the most prominently, and the decentralized attribute is the weakest, whose security is between the two. However, the project takes the three into consideration in terms of the technical mechanism and program function. Yet, the focus is different.
The project interprets the “impossible triangle” by means of thinking and design that focus on technical aspects and key issues.
The security level first guarantees the assets security and freedom of the ecosystem participants, and meanwhile ensures the rationality and security of the overall framework design, and finally takes its system updating and safe recovery into consideration mainly by means of player autonomy, modern cryptography and transaction verification mechanism that prevents BP/developers from cheating.

3. Development difficulty | 8 points

According to the summary of the project white paper, the blockchain game can be generally divided into four developmental stages.
(1)Using the homogeneous assets for the settlement of the game "gold coins";
(2)Free conversion of the game "gold coins" and props;
(3)In-chain operation of critical rules;
(4)Overall in-chain operation of the game
The game in-chain operation is the final form of the industry. Based on the above summary, Cocos-BCX proposes the future development prospect, mainly represented in seven aspects:
(1)Players having a lightweight full-node environment;
(2)The service stack operating in the blockchain environment;
(3)The game engine as one of the node infrastructures;
(4)Providing a joint development/debugging environment including engine, visual IDE, and chain network interactive interface;
(5)a set of asynchronous consensus tasks between nodes to ensure the trustworthiness of the engine environment. This consensus may be based on the discrimination of feature code of
the engine critical function's target code
(6) The game code (contract) is executed by the secure virtual machine controlled by the engine, and the key numerical calculation of the contract may adopt
the “Trusted Execution Environment” scheme, which is executed independently of the main part of the contract;
(7) The key process of the contract is witnessed by the adjacent or related nodes (like players in a copy).
u Analysis: The project covers a multiplicity of technical characteristics and functional mechanisms. The overall development is rather difficult. However, it is highly practicable in terms of performance.
At the initial stage of the project, four stages of blockchain game development were analyzed. After combing, the highest prospect was proposed, implicating to create a complete multi-platform game running environment, which can provide game developers with convenience in developing blockchain games and a perfect ecological environment to the maximum, while bringing game users a brand-new gaming experience and a game form that transcends the previous ones.
Based on the initial project prospect, numerous technical goals and functional modules are listed, indicating that the technical support for the project vision is rather effective. However, as public blockchain of the industry application basis, it encompasses various technical applications and functional modules. Comparatively speaking, the development difficulty is rather big. Meanwhile, as released by the white paper, the theoretical throughput of the Cocos-BCX test chain can reach up to 100,000 tps. The actual throughput is approximate to 3,500 tps, and the block time is 3 seconds, that is, the information broadcast across the entire network is completed once every 3 seconds. It can be seen from the project technical performance data that it has a relatively strong realistic significance. Therefore, on the whole, the project puts forward a sizeable technical challenge, and in the meantime has a reasonable practicability, therefore, it is worthwhile to look forward to!

u Analysis: The game user and developer group are highly active, and meanwhile the publicity of the media and news client are enhanced. The overall heat and operation and maintenance thinking are well-balanced. However, the current community operation link is relatively weak, and requires improvement in the follow-up.
Presently, the number of community fans is small. Therefore, the operation link of project content is rather weak. However, media communication and news broadcasting, two links of propaganda and promotion efforts, are quite effective, basically realizing a timely and real-time posting of the latest developments of the project. Although the media and news client are widely disseminated, their social interaction is relatively weak. The social platform has its own communication limitations. However, it is highly involved in interaction.

(VIII) Social Response | 7.78

User A | Point: 7.9
Comment: From the perspective of production mode and commercialization, this game is the most sophisticated. So I think this project has a very extensive application scenario, especially for developers and users.
User B | Point: 7.0
Comment: Currently, it seems that the game industry is greatly influenced by macro policies. Tencent's recent performance is a case in point. However, the project orientation is quite good.
User C | Point: 8.0
Comment: The technical advantages of the project are particularly prominent, and it also seizes the development opportunities of the blockchain. However, ultimately it needs to undergo the test of the market.
User D | Point: 9.0
Comment: First of all, COCOS has a large number of developers, solid underlying technology and reliable team work, which is worth looking forward to. Of course, great "undertaking" calls for enormous input, especially in technology. The way is arduous and long. Come on.
User E | Point: 7.0
Comment:
As a game practitioner, I would talk something about Cocos-BCX project: when the concept of blockchain game is put forward for everyone to consider, at this stage, it is no doubt that the dimension (type) of the game is developed from the perspective of "inheritance" and "tracing its very origin". If the Cocos-BCX project can be applied by game developers in terms of "development kit", is easy to learn and use, and allows the mobile game developers to shift to the development of blockchain games without a threshold, then the game dimensions and users can be further expanded. In a word, phenomenal games of blockchain games need the support of Cocos-BCX and the efforts of developers, both of which are indispensable. It is hoped that the team will make great efforts in development and publicity. "Coin friends" may not need to know how the game is developed, but they will certainly care about its future space. Such evaluation can only be called prospects and expectations. It remains to be determined whether the project adopts capital operation or the mode as solid as the old engine of COCOS till the project is landed.

III. Evaluation Summary

The project orientation is accurate, and the team has a strong lineup. It merits pointing out that its technical strength and model architecture design are particularly prominent, and there are an array of investment and cooperation institutions with strong strength. However, at present, the code has not been open sourced and the community operation and maintenance is deficient. The information disclosure of the Token link is not particularly perfect, and individual investors may care much about it. The Roadmap of the project development is all too simple. These are the deficiencies of the project development at the current moment.
