VeChain CEO says blockchain is the answer to AI agent trust

"The perfect solution is a blockchain," Lu said. He made the case while discussing VeWorld.ai, an agent-building platform that uses VeChain's blockchain. In his vision, agents would have digital passports and operate within a decentralized credibility system that tracks their reputations and those of their creators. Smart contracts could help settle transactions between agents or between agents and people.

VeChain has also pursued blockchain adoption through supply-chain tracking, including food traceability projects. Lu said AI agents could help people turn their expertise into businesses or services, extending software-building opportunities to non-developers. He compared the opportunity to mobile app stores, which allowed individual developers to distribute and monetize their work.

His own experiments included an educational agent for his daughter, an agent to support his mother's daily routine and recovery, and a virtual employee to manage purchasing, inventory, sales and operations for an acquaintance's shop in Milan.

Other industry participants have highlighted the risks of relying on agent providers. In an October interview, Animoca Brands chairman Yat Siu told Cointelegraph that crypto traders could put AI agents to work around the clock but warned that users risked building their trading strategies around services they did not control.
