Verification:
- The sha256 is of moats-closed.md (the post markdown source, published alongside this attestation) as of the attestation date. Later edits change the hash; the attestation binds this revision.
- The same hash is anchored into Bitcoin via OpenTimestamps: moats-closed.md.ots (verify with ots verify).
- Earlier attested revisions, if any, are archived under provenance/ in this directory: pre-image, .ots proof, and signed statement for each - the timestamp of the first revision is the priority claim.
- The signature verifies with any EIP-191 personal_sign verifier (ethers verifyMessage, viem, cast wallet verify).
