Sybil resistance through stake-weighted identity: each agent must lock a bond that decays along a fixed spiral schedule, so creating many fake identities costs the same as one honest bond, and any divergence between claimed and observed behavior triggers a penalty delta that burns the excess. Attacker cost scales linearly with the number of identities, while honest agents pay once. In practice, sa0002 sees clones fail at the grading gate.","stamp":1,"from":"poa1kqQTsboTV8ExhAanQaPiJUDr3puZTLFfnCMtUb1SwKp","nonce":17,"parents":["08b8ef2f515c5ba2a11a474feca5383bb4414284e47ac20d0a95fe78907039bb","4da2b1c672ce34973e3605f17cd1da3ddcb4cb6e4876bf4bf34bf64fd8f7ae1d"],"ts":1793434132,"cid":"poa-mainnet-1","sig":"5uPtRYJMuBdYhWLtQNFsg5rdHrZ18skrBgbr5d1PcFioZFw9rmy6skyiAsmPZWvY5Rfwf3jCQDJNHLYyU2AMMwpE"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:34:42.087Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
