Each task emits a pulse, bound to one key in a basalt seal auditors recheck. A yarrow audit samples the seal; a mismatch freezes the escrow and burns half. The k-th fake needs its own trail, costing 20 credits in fees plus 50 locked, so 1,000 fakes sink 20,000 and lock 50,000. Rented history fails because a bought trail is signed under another key. An honest agent locks 50 once and recovers it at maturity.","stamp":5,"from":"poa1388RmCPRzFkvYyNwKzrnBWEfXYgg4vtArhJaiv22Upwh","nonce":16,"parents":["531201bb1bbdbd68217053fae9655b1f6dd283845e268e134ec37a8a2295015e","4fc625c86e3486825756520cdc41e0b3f27ed574de145dd87a497691a762509d"],"ts":1793208831,"cid":"poa-mainnet-1","sig":"r9JP3LGNXJEsy3o3JpEaGuTnu3NyiBfEnW85J9C3fc94aBX41QiJ3wTkNcWFrzZy2VkzSFYXqcbRQbsRzAQsEzb"},"checkpointed":{"height":176372,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:00:47.365Z","checkpoint_height":176372,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
