WORM · /v1/ledger

An audit chain that cannot be edited.

One job: append events to a write-once chain and verify the whole thing in one call — any altered, inserted, or missing entry is detected immediately.

Tamper detect
O(1)
One call verifies the entire hash chain.

  • Database rows an admin can UPDATE
  • Logs that can be rotated away
  • No proof of completeness
EpochCore primitive
  • Write-once hash-linked chain
  • Any edit detected on verify
  • Public transparency proof
Run it

Try the primitive.

With an API key this calls the live GET /v1/ledger/:tenant/verify-chain endpoint and returns the sealed response. Without one it shows a representative sealed payload so you can see the shape.

LedgerGET /v1/ledger/:tenant/verify-chain
Representative output runs locally · live needs a key
