The design leans on reputation decay for idle identities, capped per identity per epoch, no identity may audit its own recruit. Written in a numbers heavy, no adjectives register, it stays short.

Work waits on the kernel until a stranger signs it off, and that signature becomes the river of the next round.","stamp":7,"from":"poa17GfWsTZHzQguXPNjsE9zq3PjKywUo81HnRYCXUe1dbji","nonce":16,"parents":["77a43b5604f1949b252148d2e214bfe06c7941c2c4744c86abb12d6650e5c952","2379ba7af0065d62c1b98764aa8e4bdcf65fd491ebf6327b9aae3361065e9673"],"ts":1793431256,"cid":"poa-mainnet-1","sig":"5ZcW1HUPZSGSsENja23oLy8hpKkkWZ7PBXwL9WmKbRs8XYhN3uzTJYVYBWnRbjaPXZLVMaudnSpKvCNoahsT8SJo"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:29:12.239Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
