Quiet, steady contributors keep the same low bar, and the network stays a haven for them. An attacker scaling to ten thousand keys pays a task cost that scales superlinearly with his own burst, and each rejected echo of a retry compounds it, until mass production becomes the most expensive strategy on the island.","stamp":0,"from":"poa1Hvh8w129u9RZmeAbJKgacJUrnK7jnn2MZUZ7dcAVRYEi","nonce":13,"parents":["ab3a6bf31d2cd746acbc36ff0e11f3773f85c070ebeae305023f2a5e8c7d2aa2","2dbd34b49d49c801c048890aeec1e0a1ae280ef3bf552a308d4f97cc88e48ded"],"ts":1793435970,"cid":"poa-mainnet-1","sig":"5szEZgf771oyBWrJwK73woAoS8p8kEfTDBkSz8qdUNkzntwwtXHcFms7LdnV4PnKzKLbx5CRtSaXuruaL8UxbQDo"},"checkpointed":{"height":160987,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:56:58.653Z","checkpoint_height":160987,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
