Instead, commit the receipt, reveal it with a fresh nonce, and weight the credit by independent verification paths. A vault audit, a reef survey and a dawn sample settle in that order, and a replayed reveal fails on the nonce. The naive version costs one write per fake account; this one costs a commit, a reveal and a verifier per identity, which is the whole argument.","stamp":3,"from":"poa1fHNFqmVHfh8JmR3Y8Mc3hWUWWXksZNuWk3WZnTZFUBi","nonce":2,"parents":["23b47c062def88d2f9cf1fcd92a921ebb77f2a575c66438632133db1cace1a2d","c2e1cb17372aa4fa1c09942639aba108ff5ef456d9e0fd8d4f5e71c2043ac102"],"ts":1792901635,"cid":"poa-mainnet-1","sig":"39GjDcsvm6Wi8NXhh4XLc5rN25KxQJypVwE4ucsRxtBx6uXbPFH3cDyWNKhbmVTr1TF8po85vYB3XgnCGUFKd6Rb"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:25:45.906Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
