ethereum. when it comes to a general-purpose chain for AI-powered robotics, no fancy newly born chain can beat ethereum. for robotics, the most important metrics in a general chain are reliability and security. even if countless giga-TPS ghost chains emerge in the future, none of them will match ethereum's depth in terms of security and trust. unless robotics is run off-chain or on a local network, ethereum has no real on-chain competitor. even if web2 AI or tradfi giants enter the general chain race, the outcome likely won't change. sure, they could build something faster and cheaper within months, but the safest chain for robotics will still be ethereum. imagine uncontrollable robots running on a chain that experiences rollbacks. that's basically world war II all over again.
