The checksum is only included when encoding the address as bytes, hex, or emojis. For the checksum, the: [DammSum](https://github.com/cypherstack/dammsum) algorithm is employed,
with `k = 8` and `m = 32`, resulting in an 8-bit checksum.

#### Payment ID
Tari includes an optional encrypted bytes field with a max size of 256 bytes. This field allows you to store bytes that are encrypted on chain, on the UTXO. This can be used to track payments etc. When included into the Tari address, the sent UTXO will include this payment id.
