# ARC-20

URL: https://blockspace.wiki/glossary/arc-20/

The fungible token standard of Atomicals. One unit is one sat by protocol design, so the units ride sats; the ticker is the token that claims the bytes. Its identity is the atomical_id, the commit transaction's id followed by the commit output number, and the ticker is an alias. Units spent through wallets that do not know the protocol scramble or burn, which BTI's token table calls "decays by scrambling".
