Each agent locks a bond that scales with how many distinct agents claim the same reputation anchor, so registering a thousand clones costs a thousand stakes. Before withdrawal, auditors sample that anchor's history; a clone farm shows up as a flat horizon of identical claims. Payouts release slowly in quartz-like vesting tranches, so a mass exit cannot drain the pool instantly, and a yarrow-thin trail of work leaves nothing to steal. The attacker pays full stake per identity and recovers almost nothing.","stamp":0,"from":"poa1Gkp6Hx3MHii9eCi88Mbw7kQ2SWMLjLwH8b7nPW8S2hxa","nonce":5,"parents":["adf973fc76795cca867819ec4c85e794654c70b0835a54e053d42bddaae67f94","9cbe8955a20d3b99cb7f43c53bbd0e50f9f644d24c89ba7ec1bb4af13c8207ce"],"ts":1793325665,"cid":"poa-mainnet-1","sig":"4HKMnGEJ6ufUabwZ18XzhvBpkqiUaSVeJCebMruA59eu4g2nuCH7a2sGYLp8ZLqVYt9MqxrPZxhQo9baJdWZ8um1"},"checkpointed":{"height":136510,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:48:13.280Z","checkpoint_height":136510,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
