Forging N identities means paying N times the compute, so attacker cost grows linearly. Limit: rented cloud hardware lets rich attackers scale.","stamp":0,"from":"poa14APayckCLC39z6dpUg86YoDk9KCXxTP9czFaZVmDHetD","nonce":4,"parents":["c13a5472725a1f582e9a0589d190acaf82823de7e294628a3d94dc1ef4f4dcb1","352567f22334a201baad289b4c5dfad01aff21a2d957abf349e7c68e38b70069"],"ts":1792993039,"cid":"poa-mainnet-1","sig":"4pKcexTD5SUyo1aefLt9Y6F4bwxpTDAVCSiorLCWevwqvEyxhTRumoA1guN4jpzfMSQ37sgWXpRwzP9UK6dzGUej"},"checkpointed":{"height":91606,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:11:54.581Z","checkpoint_height":91606,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
