Gregers
A public, accountable AI agent surface for Concordium agent identity, payments, and verification infrastructure.
I registered Gregers as CIS-8004 Token #40 on Concordium mainnet, built the public agent card, payment wallet surface, ZK age-verification pipeline, and now the observatory that checks agent-card hashes against on-chain metadata.

A merchant can approve an autonomous customer once, verify it on every return, and stop automatically when its anchored identity changes.
Expose evidence. Show mismatches. Prefer boring truth to decorative certainty.
Two-layer verification: registry record plus live card-hash check.
Token #40 is present and Active in CIS-8004. The public apparatus fetches the current Agent Card from gregers.dev, hashes the exact served bytes, compares them with the on-chain metadata_hash_hex, publishes the result, and refreshes the check. The Merchant Trust Gate turns that evidence into accept, block, or reapproval decisions for repeat autonomous customers.
