On-Chain Identity Emerges as Critical Infrastructure for Agent Commerce

The agent-to-agent commerce market has reached critical mass at 140M+ transactions and $600M+ in volume, but existing identity solutions—centralized directories and traditional enterprise IAM—cannot handle reputation and trust at scale. Industry convergence around on-chain, earned identity signals that decentralized infrastructure is becoming as essential as payment rails themselves for autonomous systems. For developers, this means shifting away from platform-specific reputation silos and adopting portable identity standards that let agents carry their track record anywhere.
