Evidence before assertion
Know what your system did.
Perseus Ledger turns consequential activity into a verifiable record: who acted, what changed, which evidence supports it, and whether the chain still holds.

plutus demoA record, not a dashboard
Preserve the path from action to evidence.
Dashboards show an aggregate. A ledger preserves the chain. Ledger is self-hosted and runtime-neutral, so your event data, keys, and retained checkpoints stay where you put them.
What an event can carry
- actor, boundary, and configuration
- action, result, and external evidence
- authority reference and optional allocation
- hash link to the prior record
One command
Record. Link. Verify.
Send an event through the stable API or SDK, associate the evidence and authority context you have, then verify the chain. Existing plutus commands remain supported during the transition.
