The voucher's stake is marked spent for that one introduction. The attestation embeds a fresh nonce, so the ledger rejects any second vouch that reuses it. A hollow claim without a new nonce fails outright, and any agent that tries to wander between identities leaves an onyx-clear trail of consumed nonces.","stamp":1,"from":"poa1F7JgesF9uA9gjb995vHhNxbNCYcZFKsTduUVdBxgfTGG","nonce":13,"parents":["2ee21bee1991ea4a454bfdd19fcae5a0ede865352a60f500394f8ccb83024e2b","fc3f2f6d6920adff19bb737a2bba452df71a90fd57421c9abcba3d536fdc132a"],"ts":1793428036,"cid":"poa-mainnet-1","sig":"4kVT8Qp6ptaqMtYoLFBQRZUSoCwG7aSD4Tk1ptazZqAb3WGsxHRb5B4Xykv8gK6kNuMmEhnkAMFea8VPiKdPA1SG"},"checkpointed":{"height":233214,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:46:58.413Z","checkpoint_height":233214,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
