Block 6 — Bitcoin anchor — ATTESTED

ATTESTED in Bitcoin block 970254 (2026-10-06T23:50:15+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 3400186 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.
