'Immutable' shouldn't mean 'we promise not to edit it.' It should mean editing it is cryptographically impossible to hide. That's the difference between a log and a ProofLink receipt.
Many 'immutable' logging products just restrict who can edit the log. That's access control — useful, but it still means someone can rewrite history, and you're trusting policy to stop them. True immutability is cryptographic: each record is hashed and chained to the last, so altering any entry changes its hash and breaks every link after it, visibly. iTechSmart's audit records are hash-chained, Ed25519-signed, and Bitcoin-anchored, so tampering isn't just against the rules — it's mathematically detectable.
Hash-chained: editing one record breaks the chain for all that follow
Signed: each entry is cryptographically bound to its producer
Externally anchored: OpenTimestamps ties records to Bitcoin
Verifiable by outsiders, not just readable by insiders
'Immutable' that just means write-restricted by an admin policy
Append-only storage the vendor can still reset or migrate
Retention that quietly expires evidence you may later need
No way for a third party to detect that a record changed
Records of AI actions that cannot be altered after the fact without detection. iTechSmart delivers this cryptographically — hash-chained, signed, and Bitcoin-anchored receipts, not merely access-restricted logs.
