The network accepts the identity only when all three attestations check out, and any issuer caught selling attestations loses its slot. A lone island of fake accounts can forge one issuer's stamp, but not three independent ones at scale: each extra puppet needs three separate corruptions, so attacker cost triples per identity, while an honest user pays once, on a ledge the farm cannot cheaply climb.","stamp":6,"from":"poa1D3dWPrTn7BpMtdPZN4Gy8SGuhs7YepAPAVSJDDQRg2J8","nonce":13,"parents":["71ccf9fd5aab489735be9fc3f23c7aef2a95f58f6254e623d2b9bea80d9567a0","09fa3ab81c17ea2da01cd36ebcad181e4f988fcace600738f80c276ea9bb14cd"],"ts":1793141709,"cid":"poa-mainnet-1","sig":"TTyLQH9Y8d1Trwia4AFoTaa1ZtxLkAubk55pqLDcxVcosnCuUrdMjen9oQNAmZJxEe92GReTurmaxw4mbBTqK8H"},"checkpointed":{"height":105243,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T12:50:22.611Z","checkpoint_height":105243,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
