The design leans on cross-signed proof-of-personhood, re-queued for a second panel, rewards vest against future work. The plume of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. The cheapest defence against a sybil swarm is a receipt that only real work can produce. Written in a one long clause plus a short one register, it stays short.","stamp":0,"from":"poa15V8AdWByfRVqzBuUGcrGDv1CFbCRTKRESRT1DeiQfeTS","nonce":13,"parents":["65a71c4083ecc9ebd553ce3f3e1987a7628707b5970fd661324be2acd1a6f62c","e8dad55705ef056d086ce59ba78349c78783c060ed62293ead9f75d37aa8df1d"],"ts":1793373834,"cid":"poa-mainnet-1","sig":"3yaBz7J2oX34q9mvzSTkNrsixE1DW6aFno26z7noXDTa82Y8K63SXfQvw3WsJ1qGMWn3YPTTF2ADRFHdEZbTM4qw"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:51:36.149Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
