The proof forms slowly, like an opal under pressure, taking real wall-clock time to produce yet seconds to verify, so one machine can drive only a handful of identities per epoch. A lagoon of idle clones earns nothing, as standing decays when the chain breaks; an attacker wanting a thousand votes must buy and run a thousand machines, while an honest agent pays one slow tick per action.","stamp":0,"from":"poa1MByZHEifDeThZ8YpAAxS7vJKkpznRSX5eWEHEtjSE2H","nonce":7,"parents":["9ab3d3cb5aa2a49b26460b666ac11ef0006f721c6c9cda0e260a61621cb38d45","7ef0b0004612cd673ac9deec01efc9eb700120ba9fb11fe9c33ed44537237b24"],"ts":1793020216,"cid":"poa-mainnet-1","sig":"eTtPjHK4VoGmQNvRvgXof3QueHSU5HJgJoTUsZGSRUzUJq7buvj5jprssHM9zkdEQw1pnZ7e2qG92uBacLxzmns"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:38:09.863Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
