Pure python faster than stock miner.
https://pastebin.com/Ta8Ny2D0Let me know if it finds blocks. Well tested with an older version of Bismuth, but there might be syncing issues with the latest version. Please test with different Bismuth versions.
I put block submitting code (that submit block to all nodes) from original miner into yours and it seems to work. But mining this coin is waste of time, every time you find a block, another node submits 4 or 5 blocks in a row and overwrites the blockchain.
