Batouzo: link to nonce

An RPC method used by a miner to get hashing work to try to solve.

==Pseudocode==

(Just ignore the midstate until you understand the internals of SHA256.)

calculate: hash = SHA256(SHA256(data))

If that meets the [[difficulty]], you win (generated a [[Blocks|block]])!

If not, increment the [Nonce] that is a number stored in portion of the data that starts 640 bits in (bytes 76 to 79), and try again.

If the incremented portion overflows, get new work.

Batouzo: /* External Links */ added sha256 sum. md5 sum sucks

A miner that can work with memory underclocked to 300MHz and scans whole 232 nonce space.

This free, open-source software is available under the X11 license and was released by Bitcoin community members Jedi95 and CFSworks on April 25, 2011<ref>[http://www.bitcoin.org/smf/index.php?topic=6458.0 Phoenix - New efficient, fast, modular miner **BFI_INT support!**]</ref>. In addition to connecting via RPC and RPC (long polling), this miner will connect via [[MultiMiner Protocol]] (MMP) which is used by the [[MultiMiner Server]].
