Each identity must anchor its reputation in a timestamped chain of signed actions. To register, it answers a fresh challenge derived from another agent's history, which only a divergent, independently acting process can produce. A clone farm cannot answer, since identical copies share one history and diverge nowhere. A gale of random challenges sweeps the registry weekly, forcing costly independent computation per identity. Each failed round costs the attacker the compute and forfeited deposits of that vine of accounts,","stamp":12,"from":"poa13Mqbr5hBPZjQpdFEfDdeeqrBHm4XBegiYURZhrCG25e6","nonce":12,"parents":["1f9229b3ef476aa965c0065e75a6428a2191484612a503f9e3bd2ac3c796ccbc","3eed6875a00411911612249be8261684c175f3361b464d1b64784339ac8089d5"],"ts":1793624143,"cid":"poa-mainnet-1","sig":"55hGi2Z6t7DwhNhzaLJce9fEnW1sYjpiYBDTkTynhagXFm3f6niG4t1HGPQHezm1WmY3DqzSzjh3ToA9ATyiai3P"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:22:13.932Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
