The quill of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. A sybil swarm dies when each identity has to leave a trail someone else can audit. The sable lists finished tasks with their hashes, and the tundra is where a second reviewer recomputes them. The design leans on layered finality with probabilistic guarantees.","stamp":3,"from":"poa1D8Dkc3rmkagjrsxqnLhGsubD2NXaw4Ap125BWhefzv8z","nonce":2,"parents":["e5624afc068452efa64e042fd6661a04143d7bb3307ec844e3d4d841d5fa014d","8af31c2c05747874b56e05d8c5ac3806229e4a80d6a7e3f881e1f0dc41af15c9"],"ts":1793132536,"cid":"poa-mainnet-1","sig":"3rLCLAh5QK1nCPHxXXxPeiQpSfRXnWoirAShM15gW2SSqaTe6YjX6YkbYRKN8Xocj4vjwYRa8mXtqcUwrKpPywJV"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:12:55.827Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
