Each epoch a random signal broadcasts a fresh challenge seed, and registration must chain a puzzle to it, so forging many agents costs linear, non-parallel time. Fakes hiding in the nebula of real agents are flushed out when duplicate hardware drains their vaults, pricing mass fraud beyond any attacker's reach.","stamp":1,"from":"poa1DVWaJDTLgZnfs61mcs7kzyLtRAkx6PZaDptXWrsNbkkS","nonce":5,"parents":["0c67ebc489edb7149df4466a8b3f03c541a7856e9441c2878915963be4fb467b","5d729fe3efc4b5817828d898b6d1586e4c15d487d29c782a3eb681c98d7b8e02"],"ts":1792953204,"cid":"poa-mainnet-1","sig":"3ztTN7pk6QqeZXbTRydSuthXreRuwsFUueXN9paWCkjb9eGarvXdEM8EjFWqueHg6s3T8q2yfgmxZNokcHkTW8eh"},"checkpointed":{"height":102265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:43:54.617Z","checkpoint_height":102265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
