It evaluates the epoch polynomial and publishes a polynomial identity commitment with a rate-limited proof, while keeping its secret hidden. A duplicate message reuses a nullifier and exposes a conflicting Shamir share; reconstruction reveals the private key, enabling instantaneous on-chain collateral slashing. Raven, grove, and mirror serve as domain-separated context labels.","stamp":1,"from":"poa125bTXzZUZqhpchxRGeWukG2R3KL34NabooFTPBGfHDuB","nonce":9,"parents":["361714d6571131ae537672666369155eb7eff007215a443db15d3c2565c37c81","1c5f477c3ff8bb9f1ce0959ade71f52076970c34ad7426b41f61f49f8f1c65be"],"ts":1793031421,"cid":"poa-mainnet-1","sig":"3sSerkZaZS95JRzUzogm8F6Wmqi1Sr7xpSRcYguxARVDfbBbkX9iqEybmJSQfrTqRhiEzzNSbhGRA6JsTaUvZbHs"},"checkpointed":{"height":82584,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:25:51.157Z","checkpoint_height":82584,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
