Microcash - General Discussion

Microcash is a new form of cryptographic currency, currently under development. Bitcoin has been a genius proof-of-concept and proof-of-adoption digital commodity. The Microcash project hopes to vastly improve upon the distributed cryptographic currency idea with numerous innovations that current crypto-currencies cannot implement due to the nature of the bitcoin protocol.

RPC API documentation for Bitcoin Unlimited/BCHN still accurate?

I was looking to calculate the fee of a transaction that is still in the memory pool. I was going to do this by looking up the amounts of the inputs and subtract all the outputs from it but then I noticed the getmempoolentry RPC also has a field named "fee". That would be exactly what I'm looking for except it's marked DEPRECATED in the docs?
It works just fine in the latest Bitcoin Unlimited release. Is this really going to be deprecated in the near future or is that a leftover label from the Core code?

Write your own Bitcoin RPC API in Javascript (Node.js and React)

If you are running a full node, it's easy to setup an app that interfaces with it using a backend API such as Node, Python, etc. There's a good tutorial here about it if you want to build Node/React Javascript apps on top of Bitcoin Core! You can make a block explorer, testnet wallet, node dashboard, and more.

RPC API - How can I check from which addresses bitcoins spent

I'm trying to implement some methods from rpc api.
In my app user's wallet is bitcoin address, and user can recieve and send bitcoins. For sending I use 'sendtoaddress' method, I can't use raw transactions right now, because my app also works with cryptocurrencies that doesn't have raw transactions. The problem is figure out from which bitcoin address (i.e. user's wallet) 'sendtoaddress' method took bitcoins in order to keep balances of my users correct, ideally using only RPC API.
I tried decoding raw transaction from txid and searching for 'vin's, but to success. I also thought about using bitcoin account instead of addresses, and create bitcoin account linked to bitcoin address, but how much account can wallet.dat hold? Can anyone have the solution?

Chain Query [Alpha] - A web based interface to the Bitcoin API JSON-RPC

Originally planned on holding off on releasing this until all the API commands were integrated, but with the recent large increase in transaction volume, an Alpha release with what is ready seemed appropriate.
In particular estimatefee and getmempoolinfo are now publicly available through your browser, along with 25 other API commands.
Built for the average Joe to explore Bitcoin's core API and to serve as the foundation for PHP web applications to easily communicate with bitcoin core.
When all the Bitcoin Core 0.10.2 commands are complete the whole thing will be released on GitHub as open source.
So without further ado, http://ChainQuery.com/bitcoin-api
A couple quick explanations:
To see the size and # of unconfirmed transactions in the node's bitcoin mempool:
http://chainquery.com/bitcoin-api/getmempoolinfo
To estimate the fee required to have a transaction confirm within the next "X" blocks enter the number of blocks here:
http://chainquery.com/bitcoin-api/estimatefee
To see if your transaction is in the nodes current memory pool enter the transaction ID here (for a readable result select "decoded"):
http://chainquery.com/bitcoin-api/getrawtransaction
Currently supported commands (27):
I hope you like it so far, any questions or feedback are welcome and appreciated.

libbitcoinrpc - Initial release of a C library for Bitcoin JSON-RPC API.

I am happy to say that after several weeks of writing tests and documentation, as well as hunting for memory leaks and bugs, my little home project has been released: libbitcoinrpc-0.1.0 is a standard C library for making RPCs to a Bitcoin node (Core and alike).
The library aims at providing a simple and robust API: to make a call to a listening Bitcoin server, you have to initialise four components: a client (handing the connection), a method (together with some parameters), a response holder, and an error handle; then pack them all into one bitcoinrpc_call() function that does everything for you. Next, check for errors and unpack JSON data from the server.
The rationale behind making yet another RPC library for Bitcoin is twofold:
  1. I couldn't find a well documented library only for this purpose that would be written in standard C.
  2. I believe that using RPC API is a proper way of developing your own Bitcoin software, if like me you are not an expert: instead of writing crypto code that is almost certain to contain many bugs and consensus discrepancies, you rely on the the standard Bitcoin implementation (possibly patched to suit your needs) and let it do the hard work, while all you have to have is just a stable and relatively fast interface for controlling a full node.
Anyway, I invite you to download the code, test it and send bug reports:
https://github.com/bitcoinrpc/libbitcoinrpc
Cheers!

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

Is there a python (or other) library to send raw bitcoin protocol commands to a peer?

From the protocol docs, there are some interesting low level commands that aren't really surfaced in the client RPC API. Is there a python, ruby or nodejs library that will allow you to connect to peers and send protocol commands?
Something like:
python bitcoin_wizbang.py start python bitcoin_wizbang.py connect 88.99.167.175:18333 python bitcoin_wizbang.py send_command getheaders python bitcoin_wizbang.py stop
Thoughts?
