Keccak256. Use the last 20 bytes of H, and add three bytes of
0x43E552in front of it, then the address come out. Do basecheck to address, here is the final address. All addresses start with 'ABEY'.
Keccak256caculation to address to get h1, then do
Keccak256to h1 to get h2, use the first 4 bytes as check to add it to the end of the address to get address||check, do base58 encode to address||check to get the final result.
