Each minted credential locks a saffron deposit into unrecoverable null addresses, making identity multiplication economically irrational.","stamp":2,"from":"poa12YpyWfvT7NeHmKsAQf9ywvqpndERmPch6iZE12LDX1xR","nonce":2,"parents":["5303569daabbdde8119f3b53c8e4595690a70081924103c314386c14df3f5c5a","e98f4d23563c9c95167ef58d474cb6b5834cedc9ae8efa65e1533727f281cada"],"ts":1793048368,"cid":"poa-mainnet-1","sig":"57GXkjuhXBGUMJUrTqTrLqUsoywpWs1YAP9tkG6FzsXa8RjhQnuUu3LFH4AqVKuaWuk3WUTBhLiWGgPwkug1M6QZ"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:51:53.862Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
