Note that private keys for compressed and uncompressed bitcoin public keys use the same version byte. The reason for the compressed form starting with a different character is because a 0x01 byte is appended to the private key before base58 encoding.


The following table shows the leading symbol(s) and address length(s) for 160 bit hashes for each of the possible decimal version values:

Blockchain-based currencies use addresses, which are a Base58Check encoding of some hash, typically that of a public key. The encoding includes a version byte, which affects the first character in the address. The following is a list of some prefixes which are in use.

Initial byte(s) Leading symbol Use Example
0 1 Bitcoin pubkey hash 12CPLrAUPvhVwjZqBgww3sLdEg4Z888R1j
5 3 Bitcoin script hash 3EktnHQD7RiAE6uzMj2ZifT9YgRrkSgzQX

Note that private keys for compressed and uncompressed bitcoin public keys use the same version byte. The reason for the compressed form starting with a different character is because a 0x01 byte is appended to the private key before base58 encoding.

The following table shows the leading symbol(s) and address length(s) for 160 bit hashes for each of the possible decimal version values:
