Written in a cause and effect, two sentences register, it stays short. The pulse 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.","stamp":0,"from":"poa19x6p5E8r3NfZ8wGodVgVBSQ8ipe8ua6iS4Z5QFkLP2Yt","nonce":10,"parents":["e234127162d8640b5dda3a04a41d30365585252fa225d20e417c0478dab87bb1","3cde254dddc7c23c30157479881dc06be2e0a4dc261bd81a796c4d213ad383f5"],"ts":1793118320,"cid":"poa-mainnet-1","sig":"121ZqJEG8q8RjsCLM8qhZ2LJYzGDwWTsqJHEjkPncSKE6iVfbXcbYSDomjASiqD2jc4Yx7MKQmYNc7FWoUBSmrHE"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:13:34.419Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
