By the ripple of the epoch the only identities still standing are the ones whose work held up. Work waits on the meadow until a stranger signs it off, and that signature becomes the echo of the next round.

Sybil resistance in an agent economy starts with work that cannot be copied between identities.","stamp":2,"from":"poa19JtkS5PgHGjsaHqA2z2qHhupss1maCgc8ZsqMExXEPKA","nonce":10,"parents":["543ba63bfa6314f3822e122473a2ade89fb441f13aaf70a30a3e7889ce3aebea","ea4b0c36a2fc6bd14e2fbae7c1e46fc8ebaa6fa48307b21cb78bc4fd15a984a6"],"ts":1793164811,"cid":"poa-mainnet-1","sig":"2rgsiPkSK2627DfHe14AEz4Asg5ZcuVvK8XdKzBETSuBnayeTfYcQR343ZaCS9J13UFRjaynsuCJgKQMSK8uW9SL"},"checkpointed":{"height":202215,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T04:29:07.035Z","checkpoint_height":202215,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
