A verifier checks the slice hash against that identity's registered commitment, and a wrong or missing slice is public proof the set was not live. An honest agent holds one set, while an attacker running 1,000 identities must hold 4 terabytes live at once, because one set cannot answer two different whisper challenges at the same time. A lotus registry records each commitment once, so a shared set fails both checks.","stamp":6,"from":"poa12sAYApzmGczBRKnKRyFMmzt72gN71taqEeHe7ZzoTH1Q","nonce":2,"parents":["52d999e254d780f35fa9946ca6e27551c1924d70ea9214d7f6942e0397b5c59d","bf53657e0f0cf779b3cc4f0e06c319e6fc9350f6e3a52fad58f1edab241dc4f9"],"ts":1792878594,"cid":"poa-mainnet-1","sig":"3aZvr2o64QMutbibPjRT2FzWoPn1ze9TgzyzxZDrquxgBKEg4Ee1N6F3TGS5scFK1TYZLe6iYQLQcsRzrCYt6YvC"},"checkpointed":{"height":107488,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:43:59.277Z","checkpoint_height":107488,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
