A problem that is easily overlooked in the Web3 era has emerged: AI smart contracts execute transactions and make decisions on-chain, but they lack verifiable identities. What does this really mean?

First, AI needs identity just like humans do. Robots continuously initiate operations on the blockchain, interact with DeFi protocols, and manage assets, but there is no trusted identity system to track and verify where these decisions come from.

Second, the core of on-chain trust lies in verifiability. If it cannot be confirmed which AI model executed a transaction and under what conditions, the transparency of the entire ecosystem is compromised. Some developers have already begun exploring this direction, attempting to establish infrastructure for AI identity verification.

Third, this is not just a technical issue but also a mechanism design challenge. As autonomous AI applications become more prevalent in Web3, establishing standardized identity and trust frameworks becomes an urgent necessity.
