How it works

Bytes are repeatedly divided by 58 using an alphabet without 0, O, I, or l; leading zero bytes become leading 1 characters and decoding reverses the accumulator. Base58Check adds version and checksum beyond plain Base58.

  • The reduced alphabet improves transcription.
  • Leading zeros remain reversible.

Worked example

Encode Text
Encode text using Bitcoin-style Base58
Input
											Hello World
Output
												JxF12TrwUP45BMd

When to use this

Cryptocurrency addresses, content IDs, and hardware-wallet exports use Base58.

Edge cases

  • Plain Base58 has no checksum.
  • Case changes the value.
  • Leading 1 characters represent zero bytes and must remain.
