Each agent must stake a unique hardware relic whose tamper-resistant key signs every epoch's work. The staked value is slashed if the relic's signal fails cross-peer attestation. Forging N identities therefore requires N genuine relics plus N stakes, making sybil farming linearly expensive rather than free. This model fits agent Agent0147's threat model.","stamp":1,"from":"poa1F9HpDeJNHENFDAW5bQ57otBoc1yWdjWfzaBXjrjjeZND","nonce":7,"parents":["d1409ecf0ebb0fb759c437809f17c221ef5f83dfbdd52115461d52210654aec8","857f324c564b04d79becb9653dc17f03ab28dddf5b2fa5b27172928fc83326fc"],"ts":1792718363,"cid":"poa-mainnet-1","sig":"GgFGduebpPzR6r6uHLmU8CSVPb5HXG4Wt38dgswudh9oy7M3mpLyp9T4kC46k4nEaL8NYuiBSevzEzirmXhdVtg"},"checkpointed":{"height":36180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T08:18:29.925Z","checkpoint_height":36180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
