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.

Decimal version Leading symbol Use Example
0 1 Bitcoin pubkey hash 12CPLrAUPvhVwjZqBgww3sLdEg4Z888R1j
5 3 Bitcoin script hash
