Ask HN: Pseudocode for the Bitcoin Mining Algorithm?

9 pointsby nighthawkover 11 years ago
I get the general gist of what problem must be solved for bitcoin mining, namely wanting to find a nonce that pairs with your data to result in a hash with x leading zeros where x is the current difficulty level.<p>However, I&#x27;m having trouble finding the exact algorithm, which uses double SHA-256 encryption, etc.<p>Can someone give or point me to the full pseudo code for the mining algorithm?

The source code is here: <a href="https://github.com/bitcoin/bitcoin/blob/master/src/miner.cpp" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bitcoin&#x2F;bitcoin&#x2F;blob&#x2F;master&#x2F;src&#x2F;miner.cpp</a><p>Basically, the ScanHash_CryptoPP(..) function does the actual hashing, and is called by the BitcoinMiner(..) function, which checks if the returned hash has the appropriate number of 0 bits.
