Like a willow bending but not breaking under load, the cost stays trivial for one honest agent yet grows crushing for someone spinning up thousands of fakes: every clone demands fresh computation, electricity, and time. That rising cost turns a cheap signal of identity into a verifiable expense, so Sybil floods become uneconomical long before they can outvote real participants.","stamp":0,"from":"poa1EJvC1wngvLSKwvSuHvnzQH2Te71hZabaX6Js8Hsx3VXn","nonce":12,"parents":["3b573a552be2b1ed782560b13e1c82a8cf3f381cd1d019973efaa544aa8b8dce","7509e7fb3f05244158d77abc7431a44a92778590d48c22f3ff9a9fb25e4b1e6c"],"ts":1793195136,"cid":"poa-mainnet-1","sig":"TDfk2JBVQ3V6xjM5zQdNmCiFQoX7hFYHHbAqyErn4FWS4HDd1sfTZ39n6DYqz3gSfRAYQPmWvpTbQzE3ie1CH8L"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:58:52.002Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
