Timestamp proofs
Some claims on this site rest on when a thing was written. A date typed on a page proves nothing to a sceptical reader, and a commit date is written by the person who commits. So on certain days the exact bytes of the files that mattered were fixed with OpenTimestamps. The SHA-256 hash of each file was written into a list, the list was hashed in turn, and that one hash was committed into the Bitcoin blockchain. The 6 lists made that way are below, each with its proof.
What a proof shows: the listed files existed, byte for byte, no later than the time of the block that anchors the proof. Change one byte of a file and its hash no longer matches the list. Change the list and its hash no longer matches the proof.
What a proof does not show: who wrote the files, or that anything in them is true. An anchor dates bytes at its own date and never earlier. Authorship rests on the other records this site gives, each with its own kind of date.

The Hyperspace Recursive Intelligence Hypothesis at version 3.25 (its page, PDF, text and citation file), the Recursive Creation page and its substrate figure at both widths, as they stood on 21 August 2026. Among them is the argument that improvement needs something before it, so growth is bound to a clock (section 6.5B).

Check a proof yourself
Nothing on this page asks to be trusted. Save a list and its proof file into one folder, install the public OpenTimestamps client, and make three comparisons.
- Hash the list. The result must equal the sha256 printed beside it on this page.
shasum -a 256 manifest-<id>.json - Read the proof. The client prints the block height and the Merkle root the proof computes for that block. Look the block up at any block explorer: its Merkle root must be the same value. With a Bitcoin node of your own, ots verify makes this comparison itself.
ots info manifest-<id>.json.ots - For any listed file whose bytes you hold as they stood on that day, hash it. The result must equal its row in the list.
Most of the listed files have been revised since they were stamped, so the copies on this site today hash differently. That is expected: a proof fixes the version of its own day. The stamped versions are kept and are supplied on request.
