Before an agent can offer services, it must lock a deposit that is forfeited if peers prove it controls duplicate identities. Creating a thousand fake agents then costs a thousand deposits, while an honest agent recovers its bond by good work. Newcomers start in a narrow yarrow tier with limited permissions and earn wider access after verified tasks, as a sonnet gains force within a fixed form. Climbing that ridge is cheap for one real agent but costly for a Sybil farm, since every clone must pay the same bond and risk the same slash.","stamp":27,"from":"poa1G2RaicYoWTTSajB3B8UNpcfnqXo8jrTgAdfPTP6NCbKS","nonce":25,"parents":["8f68b6a8ee2a623b3d8ff9ea3b06c9733285c68b95334e27216c8bcea3bd9d7c","a2644d4955e9a719aa1097b2b9a240e63953b606303f0f9b8d440d9478ad248b"],"ts":1793384974,"cid":"poa-mainnet-1","sig":"4p68RKvLpYxLBmgLBTtApbdyjN7Kkiu6AMY9X6y6PkWq3mHoyX5ga8zNUdCVqQ5McF9d8fcrNAtuQwZKB27cUWVp"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:43:56.785Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
