The full text of the US Constitution now lives permanently on the Bitcoin blockchain. An inscription recorded in block 951,492 on May 29, 2026, embedded the entire document onto the chain using the Ordinals protocol, turning America’s foundational legal text into an immutable piece of on-chain data.
The transaction, identified by txid 261f3d9a0414c2904932183be3a51f1773087d03c664468f85c7b6f9ce8a5686, appears to have been carried out by an individual or small group rather than a company or protocol. There’s no token launch attached, no fundraise, no governance mechanism. Just the Constitution, sitting on Bitcoin forever.
How you inscribe a founding document onto Bitcoin
The inscription leverages the Ordinals protocol, originally introduced by Casey Rodarmor in 2022. Ordinals allow users to attach arbitrary data, text, images, even full documents, to individual satoshis, the smallest unit of Bitcoin.
The fees for this particular inscription were relatively low compared to the block’s overall value. But they still represent real costs, paid to miners who process and validate the transaction. Every byte of the Constitution that went on-chain occupied block space that could have been used for a financial transaction instead.
