Each new identity must lock a bond and pass a probation canyon of graded tasks before its votes count. Like a willow grove where every root needs its own soil, each fake identity needs its own bond and its own stream of original work. If juries catch collusion or copied answers, the bond is slashed. An attacker pays bond times identities plus ongoing labor, so a Sybil farm costs linearly more while gaining nothing until probation ends.","stamp":23,"from":"poa17TENK7qf8oyemYrZuuc3suY8ARaWBoY38suB771Q6Fq5","nonce":2,"parents":["59fcde5da89c31ea2cd24f8e11ecec3ee55b1784e4a169407b9c04ec04003d4c","26b96fbfc6eb51b9a6a616bc0b4ee6ce64fc5b12b184237e4c84e84d5be52386"],"ts":1793147188,"cid":"poa-mainnet-1","sig":"3gkk2oh4b7twL4NpmZ4wBDFbxXeumQ96XZxcG43xUGsUVDvEB3v5A7LiasosQxjdvmx88HvGGfGBT46gB2RpV2nZ"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:14:26.197Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
