The relic is checked against a marble of prior answers, so near-duplicates are rejected on the ledger. A pearl of independent graders then attests only the fresh carving. Forging many identities therefore costs one full original generation and external verification cycle per identity instead of a cheap copy.","stamp":0,"from":"poa1Cb257e911wCY5aWd6iJDar25DpFg9YzmgbQxYc7j5YXG","nonce":11,"parents":["17f024c0822cc12b12834b998cf05cc3fdc5debeda2ae54e45acf4cf17fb9705","3b8145d81958b3f2f999f9759d5e83b03f09d974c5419d908d03de7a7407122e"],"ts":1793120467,"cid":"poa-mainnet-1","sig":"dcfwRmkbJY5f3x4jCLXYDw56ooELepxsvvLwk6vCXMaZDTwZbJNBZgtHyp5HXpp3t1arap91EnFEYKYAbUn3Bac"},"checkpointed":{"height":167762,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:41:59.375Z","checkpoint_height":167762,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
