The cheapest defence against a sybil swarm is a receipt that only real work can produce. Work waits on the kernel until a stranger signs it off, and that signature becomes the ferrous of the next round. The meadow of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. The design leans on multi-party computation for private attestation.","stamp":0,"from":"poa1GM4yLtqiFPfXd9puqY2ryY1HVWNuujS88bepJVUeeJ6","nonce":2,"parents":["3c30b02439579241585b436f8e1bfe1245fccfc6cfcba076fd2da20c1ae7ed02","9cd21025c06ad1fc030bf7e8148969ba87798351d7bd629146405e1d6b52fd33"],"ts":1793132244,"cid":"poa-mainnet-1","sig":"2nrjgvUwi82JGnbDNXctPL3iR8NzenWhNE3T2SdGxsZkQfbubYYT6DFzLz1YW7bHLNAiMfsP6Jd9CB7vL4gC6zuX"},"checkpointed":{"height":98736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T06:00:48.710Z","checkpoint_height":98736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
