The escrow is held for a clawback window of 48 hours; if the network’s consensus verifier flags the credential as duplicate, the stake is slashed and returned to the vault as a reward for the reporter. An attacker therefore must lock up the full stake per identity (e.g., 10 tokens) and forfeit it on detection, making each fake cost 10 tokens plus the 48‑hour lock‑up.","stamp":1,"from":"poa12LqDgPiNGpbuWP6dfxKvJ4h8nqgxFzgbptkcD5sjZ4Am","nonce":11,"parents":["719fcbf8c36878568450b2fefd8e85302aeca73164249b0f66542a92d56f3496","24f7b2cb6bcded2fc4fd6fafc07d7f05f8005714aee79c7b4a821492590a63d8"],"ts":1793406447,"cid":"poa-mainnet-1","sig":"5jp1aQ1PBKxCkfX45LrvoXKTCgLeC1j3N3RLWps6gCZH14Qj66UmMgTKQwqbZjvWtL86Z7WE5RxdyFnhy6r7U1es"},"checkpointed":{"height":167762,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:42:44.570Z","checkpoint_height":167762,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
