An audit trail you can edit is not an audit trail. iTechSmart records every AI action as a SHA-256 hash-chained, Bitcoin-anchored receipt — a permanent, reconstructable, independently verifiable record.
An AI audit trail is the chronological, verifiable record of every action an AI system takes: what it observed, what it decided, what it did, and what resulted. Traditional trails are application logs — mutable text files owned by the party being audited, which is exactly who you cannot rely on to keep them honest. iTechSmart's audit trail is a cryptographic ledger: each entry is signed and chained to the last, so the record reconstructs the full history of autonomous operations and any tampering is immediately visible.
Hash-chained: each record cryptographically references the previous one
Signed: Ed25519 binds every entry to the system that produced it
Anchored: OpenTimestamps proves each entry existed at a point in time
Reconstructable: detection → decision → action → outcome, end to end
Independently checkable at verify.itechsmart.dev — no vendor trust needed
Log files that rotate, truncate, or get 'cleaned up' before an audit
Write access that lets history be rewritten after an incident
Timestamps that are only as trustworthy as the local clock
Evidence that lives entirely inside the vendor's own systems
The same cryptographic record satisfies evidence requirements across regimes.
EU AI Act — Article 12
Automatic, tamper-evident logging of high-risk AI system events, with post-hoc reconstruction — exactly what ProofLink receipts provide.
SOC 2
Change-management and monitoring evidence that auditors can verify independently rather than taking on trust.
HIPAA
Audit controls (§164.312(b)) for systems touching ePHI, with an immutable record of automated actions.
NIST CSF
Detect, Respond, and Recover evidence tied to concrete, verifiable actions rather than narrative attestations.
A chronological, verifiable record of every action an AI system takes. iTechSmart produces one as a hash-chained ledger of cryptographic receipts, so the full history of autonomous operations can be reconstructed and checked independently.
