Nillion, a decentralized privacy computing network, announced the launch of a decentralized agent verification layer based on the ERC-8004 standard on its Ethereum L2 network, Nillion Blacklight. In its initial phase, Blacklight focuses on agent "activity verification." A committee of Blacklight nodes independently calls the endpoint provided by the agent and confirms the 2XX response, subsequently recording the result on-chain through decentralized consensus. The verification process comprises five steps: agent registration, initiating a verification request, committee allocation, node execution checks, and on-chain result reporting. Nillion stated that Blacklight will evolve towards "programmable verification" in the future, supporting decentralized auditing of more complex behaviors such as agent decision-making logic consistency, multi-step workflow execution, and security constraints. ERC-8004 is the Ethereum standard for agent registration and verification, designed to solve the challenges of verifying the authenticity and activity of on-chain agents.
