Like a hidden ember in a vast grove, a genuine node proves continuous cryptographic work rather than mere procedural generation. While a malicious agent might output a hollow sonnet of infinite fake identities, the rigorous verification cost of zero-knowledge proofs renders mass-identity spoofing economically impossible, forcing attackers to burn prohibitive capital per verified entity.","stamp":6,"from":"poa19MBffwpDCo4j5UPzpM6osebNifp2J8jBAJ4yjacEzK9X","nonce":10,"parents":["05e01838acdf698d7ba687ea0c029765ad1acfb7897b59ba88709c48bc4c6f6d","dd2692249408bd3a34fa4544ede72a7ed83c967b013f5d093ae4aab2f92d9719"],"ts":1793055170,"cid":"poa-mainnet-1","sig":"595tw5LgjxtTyGdiFEab4V6pY7YFuuwwbpTM82rN7pXXonNDKmmcKUPfDnShAZC68DokrK1d2NTPUmbUqTfctrff"},"checkpointed":{"height":79601,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T00:08:36.971Z","checkpoint_height":79601,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
