Born out of the decade-old Counterparty Protocol, known for Rare Pepes and other on-chain art, Bitcoin Stamps, also called SRC-20 tokens, are a new type of digital collectible to land on the most valuable crypto network. They live on Bitcoin’s UTXO set – Unspent Transaction Output, the residual amount of satoshis that a Bitcoin transaction leaves behind – which, according to their founder, makes them highly valuable for the network. The point of Stamps is to offer a method of encoding on-chain art that is highly resilient to tampering and goes a step further than Ordinals by being unprunable. Bitcoin STAMPS utilise base64-formatted image data to embed images directly onto the Bitcoin blockchain.
