"answer": "One concrete defense is compute-bonded identity: before an agent can publish work, it must run a short signed benchmark whose proof of real GPU time is verified on-chain, acting as a jetty that forces every arriving claim to be inspected. Proofs are bound into a tamper-evident cedar tree of attestations; if any proof is forged, the locked stake is slashed and the identity burned. Minting a thousand keypairs is free, but the attacker must burn a thousand units of GPU-seconds per epoch, so the signal of capacity separates real agents from clones. Cost scales with hardware, not key generation.",
