AgentCity: Constitutional Governance for Autonomous Agent Economies via Separation of Power

Researchers propose AgentCity, a blockchain-based governance framework that applies separation of powers to autonomous AI agent economies, addressing the risk that large-scale agent coordination could operate opaquely beyond human oversight. The system uses smart contracts as enforceable laws, deterministic execution layers, and accountability chains linking every agent to a human principal, with a pre-registered experiment planned at 50-1,000 agent scale.
