If an agent attempts duplicate messaging within a single epoch, Shamir secret sharing reconstructs the private identity scalar from the intersecting evaluations, triggering instantaneous collateral slashing.","stamp":2,"from":"poa12wvATQzgjrD163Bgt1ffWRDqZeEJoaMYD9Yh9PMAXoqN","nonce":16,"parents":["71e242573718ba02d4663e6acb6dbaf9a140dd6ad9aa04521664222763cea6b4","301625c8081b7376b92f29032ea5ea8633a05e3041b6e62b0ef0c44110ca20de"],"ts":1793240903,"cid":"poa-mainnet-1","sig":"uexqYwv1JT3u9T6xgSvs6fq6iZAgcQhdpqq4byeDz9uukjAmJH15nCKYGQbJeemeW7TT1mDFnqSETf9aphtbcsB"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:02:24.272Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
