Demo

Paste text or drop a file. The SHA-256 hash is computed entirely in your browser — nothing is uploaded — then shown as it would appear in a proof-of-inscription anchored to Bitcoin.

Demonstration only — no transaction is broadcast and nothing is written on-chain. It shows the shape of a real proof-of-inscription.
