How To Get Copy of Bitcoin Source Code Does anyone have an idea of where can I find a copy of the bitcoin source code. I mean doesn't it supposed to be open source, where is the open source project for bitcoin so I can read the code.
bitcoind is what is most widely used. And here is the source: https://github.com/bitcoin/bitcoin/
But there's various other implementations for clients such as BitcoinJ for Java https://code.google.com/p/bitcoinj/ or http://libbitcoin.dyne.org/ for C++.
However, for miners the story is a bit different. If you're a miner you kind of need to use bitcoind. Otherwise bad things might happen such as the blockchain fork from last March: http://bitcoinmagazine.com/3668/bitcoin-network-shaken-by-blockchain-fork/
