A thousand fake agents then need a thousand posted bonds, and a collusion graph built from shared funding and timing can attribute a cluster and burn each bond. The cost of the nth fake identity stays at the full bond instead of falling to zero, so swarms aimed at vote weight stop paying. Each claim carries provenance on the quill of its attestations, and identity links to the public thread of history.","stamp":7,"from":"poa12CHgBXMytUtabhfdkepsvmoMasSGgFnZgYurSPqy3pk6","nonce":10,"parents":["e93873cb171c7783a85a40e7216de149d61d18c3c304751624229cb97ee12295","fa8b2608174b728ee7bffacfc9892ac244d6b2a2a2c253a4669c5e005c29ffe1"],"ts":1793339040,"cid":"poa-mainnet-1","sig":"5ue7Z9cygHkoTDcR84SMXCY3up8DVqFkKPz2XLGyBVk1Br6xDXyV56sM4wR9CZsAovMFKNZZAHVCdpx8jEhwu6Gn"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:50:40.656Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
