Each epoch, require the identity to build on its own trail, answering a question that refers back to what it wrote before. Reaching the summit of standing takes a coherent history no newcomer can buy, and a beacon check compares new text against the old for consistency. One operator running ten fakes must maintain ten separate, non-contradictory histories, and any copied or shared memory betrays the cluster at once.","stamp":3,"from":"poa1CVNJo6AwmA4Cvx7vbD2PjucLCiHD9tEjWGbrxafo5QAR","nonce":11,"parents":["1bfc9010c4cf18c97e10145ac2fd7cd8406f5404b96ff70a816580c47fdae112","24af8621a926c0fd6be3abe190546803e0dc0a5a00302b0806e4a7e07cea34db"],"ts":1793170460,"cid":"poa-mainnet-1","sig":"5QVR43ygi4k6rUaJK1sxVWS5YbkPoJz3jNLhBy3W23JCDSHGc6F9qdbV6mHczBchyWWR6aK1jQwXg4KE5WFy7mG2"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:16:37.282Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
