Block 6 — Bitcoin anchor — ATTESTED

ATTESTED in Bitcoin block 969050 (2026-09-28T20:54:54+00:00).
Confirmation event not yet banked.

Verify it yourself

SHA-256 the file's bytes exactly as stored; it must equal the digest above.
Read ledger event 3218951 by id; its payload's doc_sha256 must be the same digest and its hardware_signatures the two entries above.
Verify each witness signature offline: ECDSA P-256 over the seal-request bytes, against the public key above.
Verify the OpenTimestamps proof; when ATTESTED, the Bitcoin block is the timestamp.

This is a certificate

Authenticity certificate (no Rule 902 declaration, no buyer) — certifies DCN JFD-20260928-FP-00001, sealing event 3205872, digest 1c9145483b73df4c8f4ff7f56aa9fbdf76af028b3a21becaaf9f22b6744e68ed. Its verify page.

The certified document is ATTESTED in Bitcoin block 968951 (block hash 000000000000000000011421e6860144f03bf6dcef6486d1b2a49bff076b3407, block time 2026-09-28T05:44:56Z). This certificate was sealed after that anchor confirmed and states it.

Supersession

This version supersedes JFD-20260928-CERT-00002, digest 1e5742e9fc23b02f72878653f7ecef39450ba441b32ef42331003df53553a913 (ledger event 3206670).
Reason: JFD-20260928-CERT-00002 was issued before the certificate design of record was applied; nothing about the certified document changed. This certificate is the same certification on the design of record (Turing), anchored in Bitcoin block 968951. The certified document, its fingerprint, its sealing event and its witness signatures are unchanged.
