DUST-20

Tokens whose units are carried by the satoshis holding them. A deploy inscription fixes how many satoshis back one unit, a mint inscription must sit in an output holding exactly that many, and movement is an ordinary spend whose output layout decides which whole units survive.

Created outside Bitcoin Universe by The DUST-20 community, 2024.

Where the specification lives

The specification and reference documentation for DUST-20 live in bitcoinuniverseio/dust-20 and are published at https://bitcoinuniverseio.github.io/dust-20/. That site is the authority. This page exists so you can find it and compare it with the rest of the estate.

Bitcoin Universe indexes or implements it in bitcoinuniverseio/index-dust20.
