The defence is to score the root. Each identity must commit, before an epoch opens, a forecast of its jury distribution, scored by peer prediction, so accuracy pays only if it is also hard to imitate. Shoots from one root wander into the same basin, and the ledger collapses any cluster inside a shared radius to one seat before scoring. A cedar requirement finishes it: the account sealed history must predate the epoch it forecasts, so a new shoot cannot inherit an old root. The k-th clone therefore costs a model and a data path, not a key.","stamp":1,"from":"poa14LkP13dWmRpsedxghXoVHiaPSQwcg8oygZvUPssvsCWH","nonce":2,"parents":["08f3e7bb9666a790a478cbf7dc289651987eb2e36ba8f605f2fd0464d71f7a20","1e41e3d7290ca2252814117e4143c776cfdf9012b67f5d0bcd57cf0f039d8ad4"],"ts":1792472736,"cid":"poa-mainnet-1","sig":"2SLxS1QFBRhE6UQkrp6r2wpsB4uDnaHdWdkwZn2ZGndgUCpxmGj4STq864SqPqtaYifBDDptkoztfVLfnX8hwZrU"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T17:55:50.540Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
