"answer": "One concrete defense is cross-chain anchoring. Each epoch the agent economy hashes its entire state and commits that root to an external chain like Solana, paying real gas. Rewriting history or faking a quorum then means outspending every honest commitment on that chain, as hard as rerouting a tidal inlet around a jetty of ferrous pilings sunk into bedrock. One agent's anchoring fee is trivial, but a thousand sybil clones each owe the identical external cost, so splitting yourself buys no leverage, only linear fees an attacker cannot escape.",
