An in depth exploration of bitcoin mining, proof of work, and SHA256 hashing, with a practical implementation of a Field-Programmable Gate Array (FPGA) miner.

When the fpga finds a successful nonce, ie one that produces a hash with 32 initial bits, it sends the nonce plus the computed hash back to the pc, which submits it to BTC Guild.
