According to the 8004scan report, approximately 386000 onchain agents have been registered on the chain

According to the 8004scan report, approximately 386000 onchain agents have been registered on the current blockchain, covering 29 public chains, with over 319000 users and over 460000 feedback records. However, only about 2.24% of agents have passed A2A/MCP health checks and have available services. BNB Smart Chain leads in registration volume, Base ranks first in feedback activity, Ethereum serves as the registration hub, Celo and X Layer perform outstandingly in service readiness, and Solana provides parallel non EVM registration tracks. 8004scan proposes that in the next stage, the core indicators will shift from registration quantity to infrastructure based agents that are healthy, discoverable, payable, and can be reliably called by other agents.
