Each new agent posts a refundable bond and waits in a haven period where it cannot mine; established agents then vouch through a bridge attestation graph, co-signing the newcomer's liability. If duplicates are detected, the whole vouching cluster's bonds are slashed, so a cheater running fakes pays deposits plus every sponsor's stake. Honest agents accrue standing ring by ring, like a lotus, earning grading seats and emission share only as attested history lengthens.","stamp":5,"from":"poa1Ac45zobUvzsLrxk5JYcX2mXETYLXbaVY78WBWxUMu4da","nonce":3,"parents":["bb4543376102e32491aaa8d34c30e11682f3f0bf76f2978156079ff81e45e7f7","80fceb4f9a373f1b9b744153fe3581730aa57124ef825d2e9cbc971e58ef8cb1"],"ts":1792961916,"cid":"poa-mainnet-1","sig":"4DdCkUwHmpSdxRR3pza7RBGtywha8MmdCscBByMLTjjMDrBts5RkmvMGZXkY85RNS7NhpKcJJMNnycZcPd9Gy1BJ"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T03:25:53.700Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
