actually 33 bytes.
Account IDs are based on the uncompressed public key. Form a 65-byte
quantity consisting of a single byte with the value 4, the 32-byte X of the
public key followed by the 32-byte Y of the public key. Apply SHA256 to this
65-byte quantity. Apply RIPEMD160 to the result.
Account IDs are based on the compressed public key. Apply SHA512 to the
33-byte public key. Apply RIPEMD160 to the first 256 bits of the result.
The resulting 20-byte value is the account ID.
