Live Casper Testnet provenance

Lastre

Proof before token. The deterministic offline SHA-256 seal decides the verdict. The experience layer only reads and writes to the already-live protocol.

Marketplace — live provenance badges

Every on-chain candidate is read from /verdict/:assetId. Simulated catalog items stay explicitly labeled as simulated.

Mineral

Status

Sandbox — compute locally, anchor only when controlled

Compute is local and instant. Anchor is a protected Testnet write through the gateway and may be disabled unless Felix enables the demo key.

Compute demonstrates the seal mechanism. Only on-chain attestations returned by /verdict are authoritative proof.

Lot

Mass (grams)

Captured at

Operator

Load the catalog, choose a lot, and compute a seal. No chain write happens until the controlled anchor button is used.

/proof — live transparency

Counters and recent events are fetched from the gateway. Event transaction hashes link to cspr.live when available.

—Accepted

—Rejected

Honesty frame

All mine and lot data shown here is fictional. Valid and Invalid verdicts are both written on-chain by the protocol; a rejection is permanent, verifiable proof, not a discarded error.

No screen offers an asset action. The public action is always: Verify provenance.
