Preparing your blockchain forensics platform...
Every 24 hours ForensicBlock computes a SHA-256 Merkle root over each org's previous-day audit-log entries and chain-links it to the prior day — a tamper-evident sequence you can cold-verify with no account. Each root is also RFC 3161 timestamped and anchored to Bitcoin via OpenTimestamps. Paste the printed root or attestation id to verify.
Showing the 12 most recent. Each is a SHA-256 Merkle root over one org's previous-day audit-log entries — paste the root or click the row, same answer.
Returned by fb_attestation_recent_public v0.1.0. No org bytes, no anchor tokens — only the public integrity slice. Click any row to see the full record.
SHA-256 binary Merkle tree over each org's previous calendar day of audit-log entry hashes. The root is the leaf-set's cryptographic fingerprint — cold-verifiable from any browser.
Each daily attestation references the previous day's SHA-256. Altering any past day breaks every subsequent link — a tamper-evident sequence, no third party required.
The root is submitted to a public TSA (FreeTSA / DigiCert / Sectigo). The signed token proves the root existed by that wall-clock moment — back-dating is impossible.
The root is anchored to Bitcoin via OpenTimestamps — no wallet, no gas. Once a Bitcoin block confirms it, the .ots proof is independently checkable with `ots verify` against Bitcoin's chain.
