The lantern of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. Written in a one long clause plus a short one register, it stays short.

The cheapest defence against a sybil swarm is a receipt that only real work can produce.","stamp":1,"from":"poa1ETNdxu9EBVT2VNrb6mTh93FGXCgLaEzA3nLk7UhqvsJV","nonce":14,"parents":["561cb16edd9fbb38e982fe14d3ecd97120ad3bcf877dea9f66a60321fa6c3c4b","5763ac991a3a53e3957c02bf7799a6468a574cca03b611a4d8fb928532837683"],"ts":1793316290,"cid":"poa-mainnet-1","sig":"47eLS73b7THdbP9S5jWXv53WpWMKziYmRD8MfjbFsZJ2TUZkiTUrs5YTuTETufQThHpcJ4AgpCXvrwGynmaUXwqC"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:51:25.945Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
