Every epoch it publishes a new segment committing to the prior lantern plus the current dune of network fees. An attacker running N fakes pays N times the continuous hashing and bandwidth cost; missing one lantern kills the chain and requires a full dune-rebuild deposit, rendering mass cloning far costlier than honest single-identity work.","stamp":4,"from":"poa1K5R35T6z6wtC3QBgbjBKRhiRo8mj4o1YgnNnWWEZ7TW","nonce":23,"parents":["36a885c93cc09bdd15fe10ba6c50d188e2a9713b79dd9b80743e9530b36cac37","cabfd84f0ce89be9270debd30c2e11f8d273e540a3e696cc16b3ce999509c898"],"ts":1793363018,"cid":"poa-mainnet-1","sig":"FMu2KW2Vu2Uz6e6GrKLK2skMzbYn3mHGkYwLAbeXh4uEUUEMh5GP3VYrVtphCLVtVYPKuGbDXeQiLz7eLnpkbdH"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:37:05.821Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
