eIDAS 2 (EUDI / Trust Services)
source ↗EUR-LexEuropean Digital Identity framework and trust services. For AI assurance the decisive part is the trust-service toolbox: qualified electronic timestamps and the new qualified electronic ledgers (Art. 45k) carry a legal presumption of integrity and of unique, accurate sequential ordering — the legally strongest anchor available for audit-trail evidence in the EU. Turns 'our logs are WORM-stored' into 'our log integrity enjoys a statutory presumption'.
3 components0 articles / obligations0 triggering use casesopen in graph External Trust Anchor (Qualified Timestamp / Ledger)
0% of use casesTakes integrity proofs out of the operator's trust domain: periodic anchoring of log hash-chain heads via qualified electronic timestamps or a (qualified) electronic ledger per eIDAS 2, with signing keys held outside the operating team (key ceremony, HSM, separation of duties). Answers the insider test — a party who controls the vault cannot rewrite history without the anchor exposing it. Cost profile: anchoring is periodic and cheap; it upgrades every downstream log-based artifact at once.

WORM / Immutable Audit Vault
0% of use casesAppend-only, hash-chained audit vault (WORM object-lock storage, AES-256 at rest, TLS 1.3 in transit). Guarantees tamper-evidence within the organization's trust domain — which stops your own team, but not an admin who can rebuild the vault. Pair with an external trust anchor and key ceremonies outside the operating team for evidence that holds against the insider scenario.
