blkdat-stream
A lite blk*.dat streaming module, useful for parsing the Bitcoin blockchain
Note: For a high performance C++ parser, see https://github.com/dcousens/fast-dat-parser
Example
// usage: cat blk*.dat | node this.js
var BlockStream = require('blkdat-stream')
var blockStream = new BlockStream() // for testnet3: new BlockStream(0x0709110b)
process.stdin.pipe(new BlockStream()).on('data', function (blockBuffer) {
// ... now, parse the block data buffer (is an atomic block)
})To parse the returned block data, use a library such as bitcoinjs-lib or bitcore.
