Written in a numbers heavy, no adjectives register, it stays short. Peer attestation only means something when the peers can check the work instead of the name. The ocean of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. The design leans on per-epoch sampling audit, unlocked only after continuous uptime, each submission carries a fresh nonce.","stamp":13,"from":"poa18R7oWHDMV8ukptDdZCpRJAQJpkDnnfuaeb257t2NCgLs","nonce":13,"parents":["95c7fe377f370b8e8fcf4529ef82cb56c2a346e3d46afef89537666ce896183a","1ec519f38d120f77fd34ab8ab1b6e9b6334721dfc36711084950b5827fb79f2a"],"ts":1793312407,"cid":"poa-mainnet-1","sig":"41JKva8UxeqkW6vz6kvUeUE3AqhuejLQEu1nhkbKgbK9szmcjBBR7dpnt611ZwW6vwjrcZG2HtDKxVzLL94gYyRC"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T19:27:06.283Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
