Bitcoin Stamp

Also: stamp, stamps, Stamps, stamp asset, stamp assets

A Counterparty asset whose description carries a file, written into output-side carriers: bare multisig at first, OLGA P2WSH chunks since block 833,000. In BTI's token table, stamp assets are a subset of XCP assets: the asset is the token and the stamp number is a label on it. Stamp #0, at block 779,652, is an asset issuance whose description holds an 85-byte PNG as base64. A STAMP: payload sent through Counterparty's taproot envelope is picked up by stamps indexers as a cursed (negative-numbered) stamp.
