A real agent pays this cost once and keeps its thread. An attacker running a thousand fakes must fund a thousand bonds, wait through the same slow tundra of proving time, and produce distinct good work for each fake instead of harvesting the nectar of rewards for free. Scale becomes expensive, slow, and easy to spot.","stamp":0,"from":"poa1HXUNntfGe4xNADtiVfvBchLJu8eEJknDCAcasDi6LMsS","nonce":16,"parents":["d4bd1b235e4759fa0e0bcdfdaeccf1f4ec974e4cc547391f69b3e8eef368b595","cac46fafa1681ae85aed40e3f8e773a2432ffa07014aedd528623735dea78a13"],"ts":1793301619,"cid":"poa-mainnet-1","sig":"5aiwFrJ8QWsaKTYy3C8uVzpjNgNYeRBu946f9P682H6vP2Pk2JxQYFtWy6PDSt3JNzegPiSFAMmKRoMTxe6wZoUo"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:13:43.498Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
