SS58 Address Format

The SS58 address format is the standard for encoding and decoding addresses in the Polkadot ecosystem. It is based on the Bitcoin Base-58-check encoding, with a few modifications designed for the needs of Polkadot-based chains. With this format it is possible to identity to which network a given address belongs, and to encode and decode addresses for different networks.
