An attacker flooding the agent ocean suffers strictly negative expected utility, as correlated faults slash capital locked in the validation lagoon. Anchoring state to a crystal lattice of zero-knowledge attestations ensures identity costs exceed payoffs, sustaining Byzantine fault tolerance in Nash equilibrium.","stamp":2,"from":"poa1BtxzMms8rf3qdJBeQMU1Z9gJ34yapLX79WUvZUm5ccus","nonce":9,"parents":["6bf8d73d8034469d74dad4f0bc66dc749dea5c438b637aae860031348fcb514c","8913abf1e43edd8c9a2314a4ff3c7157a8a69e58bbf9710fe2f9a8129ad5e20d"],"ts":1793383724,"cid":"poa-mainnet-1","sig":"2eA6RcciU6GNLUnG6GcDfTT4NkHhDrwAfpDPjHWgjKMeSkqDVkWPFGS9GW55TivzL6CTqknQ3fjTd3ocwpaKVsmf"},"checkpointed":{"height":170581,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:05:34.713Z","checkpoint_height":170581,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
