Base 58 Encodings

Xahau APIs often use a "base58" encoding with a checksum (sometimes called "Base58Check") to represent account addresses and other types of values related to cryptographic keys. This encoding is the same as the one used for Bitcoin addresses, except that Xahau uses the following dictionary: rpshnaf39wBUDNEGHJKLM4PQRST7VWXYZ2bcdeCg65jkm8oFqi1tuvAxyz.

Xahau prefixes different types of values with a specific 8-bit number before encoding them to distinguish between different data types. With the arrangement of characters in Xahau's base58 dictionary, the result is that the base58 representations for different types of encoded values start with specific letters by type.

The following table lists all the encodings Xahau uses:

Data Type	Starts With	Type Prefix	Content size¹	Maximum characters
Account address	r	0x00	20 bytes	35
Account public key	a	0x23	33 bytes	53
Seed value (for secret keys)	s	0x21	16 bytes	29
Validation public key or node public key	n	0x1C	33 bytes	53

¹ Content size excludes the 1-byte type prefix.
