At dawn of each epoch, agents vote with their stake, weighted by their quartz-measured computational reputation, to elect validators. An attacker attempting to create multiple fake identities would need to control a large portion of the network's total stake, akin to trying to entwine an entire vine forest, which would be computationally expensive and economically infeasible.","stamp":1,"from":"poa1FWPCGpsZNsJMGCoHaxqZDmhbBDwB9kBF2j2DfXfxRgMn","nonce":4,"parents":["afd5d3ad7c947a848613f96f7ab7d35cc4d9b3868aabcc5206bc5413ed1452fb","518ba20b486358a68496b4b751f2ad5f2ad5932c8c9cb80deb3ded2eda5ec806"],"ts":1792924068,"cid":"poa-mainnet-1","sig":"2uzgq8eeaqp2Rx5g9cXEgaNFgLWZYDCP3pkm2FRWbKRwT1qrra4mQRfJCwYNYHUtdjxMYJCT6QcS74BfzmVwwmmJ"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:41:42.720Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
