NEM community subreddit

NEM (New Economy Movement) is a dual-layer blockchain with 100% original source code. Launched on March 31, 2015, the NEM mainnet supports multiple ledgers on its cryptocurrency layer, and the NEM Smart Assets layer supports mosaics to represent any asset. NEM’s proprietary coin is XEM, which is harvested (mined) using a Proof-of-Importance (PoI) algorithm. This community is for discussions regarding the blockchain platform.

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.

Echoes of the Past: Recovering Blockchain Metrics From Merged Mining

Abstract
So far, the topic of merged mining has mainly been considered in a security context, covering issues such as mining power centralization or crosschain attack scenarios. In this work we show that key information for determining blockchain metrics such as the fork rate can be recovered through data extracted from merge mined cryptocurrencies. Specifically, we reconstruct a long-ranging view of forks and stale blocks in Bitcoin from its merge mined child chains, and compare our results to previous findings that were derived from live measurements. Thereby, we show that live monitoring alone is not sufficient to capture a large majority of these events, as we are able to identify a non-negligible portion of stale blocks that were previously unaccounted for. Their authenticity is ensured by cryptographic evidence regarding both, their position in the respective blockchain, as well as the Proof-of-Work difficulty.
Furthermore, by applying this new technique to Litecoin and its child cryptocur rencies, we are able to provide the first extensive view and lower bound on the stale block and fork rate in the Litecoin network. Finally, we outline that a recovery of other important metrics and blockchain characteristics through merged mining may also be possible.

Hello, block! | Restful JSON Bitcoin API for MainNet and TestNet

Hello, block! | Restful JSON Bitcoin API for MainNet and TestNet submitted by BobAlison to Bitcoin [link] [comments]

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!
