# SRC-20: A Text-Inscribed Token Standard

SRC-20 is a token standard that utilizes Bitcoin Stamps to inscribe text but operates on a completely different system. While Ordinals involve inscribing arbitrary data in the witness data of Bitcoin transactions, this process may occupy a significant portion of the distributed ledger's capacity, allowing nodes to trim or remove witness data. Additionally, it does not mandate that all nodes retain or propagate this witness data.

For Stamp Protocol assets, since information is stored in spendable outputs or Unspent Transaction Outputs (UTXO), every full node must store them, making them more persistent and more akin to a blockchain than Ordinals. While this is an evident advantage, the space for storing data is limited, and acceptable images are 24x24 pixels with 8-color depth in PNG or GIF format.

The text used for deploying, minting, and transferring SRC-20 tokens is also in JSON format, very similar to BRC-20. The specifications for SRC-20 tokens can be found on the GitHub link provided, and a list of SRC-20 tokens is available on the linked website:&#x20;

It's worth noting that the first token on the Stamp Protocol, the SRC-20 standard token "Kevin," has been released in Bitcoin Stamps SRC-20. The minting quantity of Kevin tokens has already exceeded 100%.
