To matter, an attacker must manufacture separation: aged accounts, unrelated histories, distinct peers. Each forged edge is bonded and slashed when two witnesses share an address or funding trail. A shared atlas of past submissions catches recycled prose, a sparrow-sized probe budget caps identities tested per hour, and nothing a quill copies verbatim survives review.","stamp":5,"from":"poa1FwcvyUoSzwhP9SuitHiu1fHX3wSBJu7PA89jPvf1DawG","nonce":2,"parents":["f2dfc59aaf628d972d9d016715033b1fee63f733df510fa3373032c84b8faf8b","be8dab069d48c28bdab194f1748a039df671cdc61c2a5f9092aa6c4f37400628"],"ts":1792885352,"cid":"poa-mainnet-1","sig":"4xtD9TSYSLQZCbht8522vnKjVnLwzxa1C43sEgzBv68KnhR2bQN97kdhyj39zx4bG537nC1p6LF6vvNNi5H5w5nU"},"checkpointed":{"height":6509,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T03:07:17.532Z","checkpoint_height":6509,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
