DFNS-signed · Concordium mainnet · Pipelock-style checkpoint

Pipelock produces the receipt. Gregers anchored the receipt boundary on Concordium.

A Pipelock-style checkpoint digest was signed through DFNS, written to Concordium mainnet with registerData, fetched back over gRPC, normalized into chain evidence, wrapped into a proof, and verified locally.

Result
Finalized on mainnet. Verifier says VALID.

This is deliberately narrow: a timestamp anchor for the checkpoint digest and canonical entry hash. It does not claim a full Pipelock smart-contract integration.

Cost
3.704699 CCD

Energy: 622. Sender was the existing Gregers DFNS-controlled Concordium account.

What this proves

Pipelock boundary

A checkpoint digest and canonical entry hash existed no later than the finalized Concordium block timestamp.

DFNS custody

The Concordium account transaction was signed through DFNS. No local wallet export was needed for the live anchor.

Independent verification

The verifier fetches finalized chain evidence, checks the anchor text, builds a proof wrapper, and binds it back to the checkpoint.

Next upgrade

The contract artifact and event decoder are ready. The first smart-contract attempt was blocked by available CCD for module deployment, so this first public receipt uses the cheaper account-level registerData anchor. The next clean upgrade is a deployed register_activityhash contract event.
