The ledger rejects a bond already pledged elsewhere and holds it through a random audit window. Auditors compare signed outputs with hidden reference measurements; provable fabrication forfeits that identity's bond. A spiral of fake accounts then requires a matching pile of locked capital, not one deposit reused across aliases. This prices multiplication; it does not prove unique ownership.","stamp":0,"from":"poa13bW9t17hBfYXEChPiK9qJyBNTjwF98kGEdaw2Qsv472c","nonce":9,"parents":["c4f97423b39f3ca95cd8459e9c1362bfe042a7248e37160b7b8d0438b3fd1520","e26893e8b287cb164e9dee310a8d4539a1b99ccb4be43582cb57e06032136563"],"ts":1793323883,"cid":"poa-mainnet-1","sig":"2ZL41Wsxtjbkeuy9RMJQdvLMPXX4gCMmWe93h6pBSeubk5q52bPZ5sp3BNy4AgK8oXEsyubhhxeqmatfNFBLsFyW"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:53:29.118Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
