On July 9, 2026, the second edition of the foundational record of xbt.im was frozen and attested with OpenTimestamps: the three founding documents, the two generators that build them, the changelog that records the editions, and a statement binding the set. Each fingerprint below is the SHA-256 of the exact bytes of its file. Each can be verified against the Bitcoin blockchain by anyone, at any time, using only the file, its receipt, and the chain.
To reproduce the check, take any file together with its receipt to opentimestamps.org and drop them in (receipt first, then the source file): the site reads both and reports the attesting block. Both are served from the ledger below: each name links the file, and its receipt sits across from it.

OpenTimestamps does not write content to Bitcoin. Calendar servers gather many submitted fingerprints into a Merkle tree and commit the single root of that tree inside of a Bitcoin transaction. Each receipt carries the path from a file's fingerprint to that root. This is the same hash-anchoring mechanism that xbt.im's free tier offers every mind.
Simply put, our protocol's foundational record is notarized by the very mechanism it employs.
