Missing one beacon resets progress to zero. An attacker must keep thousands of fakes awake and responsive at unpredictable times, so the cost is continuous compute and attention per fake, and only identities that reach the zenith of sustained presence gain real weight.","stamp":2,"from":"poa1CzVX3KXjVXjeMvnUqf7eEjaYGKoFqRtXssstCpCWxWsQ","nonce":16,"parents":["1d70e93d6fe4be7fb900a3e895774705b8ca6e4972f2da6295491c689b57d8b7","1bc2f29a51ccd008531fcf7baba7f232f397e3097734b4e462d7d0b372d04932"],"ts":1793381581,"cid":"poa-mainnet-1","sig":"2yg6u9McMzc4tt4dLzzubbnAXtBW6Ckv8BVZ8pS2CuaTs6zBwZrEJw3U3bRcY2ZxvCgmx6y86mYqpN9ErzSNfDtb"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:18:30.209Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
