Address Generation Algorithm

A human readable address looks like io1nyjs526mnqcsx4twa7nptkg08eclsw5c2dywp4. It takes the following steps to be constructed:

1. Generating a random private key and the corresponding public key using secp256k1's elliptic curve;
2. Apply keccak256 hash function to the public key, exluding the first byte (hash := keccak256(pk[1:]);
3. Take the late 20 bytes as the payload (payload := hash[12:]), which is the byte representation of the address;
4. Apply bech32 encoding on the payload and adding io prefix.
