PHASE 8 • APPEND-ONLY EVIDENCE
PROOF
THAT
PERSISTS.
Every verification snapshot is linked to the previous record with SHA-256. Changing an older record breaks the chain and becomes publicly detectable.

The record hash is calculated from the canonical record payload and the previous record hash. This creates a tamper-evident sequence.

VERIFICATION
How chain validation works
- Read a record
curl -s https://unlockpool.com/api/v1/ledger?range=latest - Inspect previous_hash
It must equal the record_hash of the preceding ledger entry.
- Recalculate the current hash
Canonical JSON plus previous_hash is hashed with SHA-256.
- Repeat backward
Any modified or deleted historical record breaks continuity.
