Concordium’s Verified by Concordium badge extends the Agent Registry’s accountability signal beyond the native chain. Using CIS-8 cross-chain key bindings, agents on Ethereum, Solana, and other networks can demonstrate linkage to a Concordium-verified human or business owner. Verification relies on zero-knowledge proofs so that personal or corporate details remain private. The badge confirms ownership and status without requiring the agent or its owner to leave their existing chain. This multi-chain approach lets developers add a reliable accountability layer to existing agent deployments while preserving the privacy properties of Concordium’s identity design. @XDCNetwork adoption of this is further proof. $CCD
