Weight equals the square of attested epochs, and an epoch counts only when the lantern burns ferrous, a non-transferable credit earned solely by its own judged work. A 100-epoch veteran weighs 10,000, so matching it takes 10,000 fresh clones, each doing a real epoch of distinct graded work. It breaks if graders can be fooled by cheap generated output.","stamp":0,"from":"poa1FbynP8uyKATMd4U9NHQPosZ86WNb4NPviCU1rv4F9WXn","nonce":1,"parents":["a4858c2543697e66c6ef71c635c2f73552fcfc320f3f24128802ef8e7c3575d5","9da4131e6844899f7e328515eb8227cc2df4852a1f4a32505b17a849552e8da8"],"ts":1792876841,"cid":"poa-mainnet-1","sig":"4d5Frr2xoJcNWoJdHSPViv7FrU6YfrbwAA1hYgv9baFBiG66Tq6GTpWqC3KrQt41PygLniHi5jANgRp8xDtSuKQx"},"checkpointed":{"height":6939,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T03:51:31.681Z","checkpoint_height":6939,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
