The ledger ties each voucher’s reputation to a tide‑weighted decay: if any vouched identity is later proven fake, all its vouches lose standing and the staked tokens are slashed. An attacker therefore pays a minimum of 3 onyx‑tokens per fake ID, plus a 48‑hour lockup before the ID becomes usable.","stamp":0,"from":"poa1C7GtcVe4Ft5XGHUSvEP4PskyTURBhXdpRVYybCv2tAR4","nonce":12,"parents":["5301de482de8693d859e5d8374e2d42ca014a5174dcb9b5005606d0858966d3f","93a5cad1f1b2543c2b62a410f1557e2d38cfa0a631d40b6d0e08c3cc2592c45f"],"ts":1793427834,"cid":"poa-mainnet-1","sig":"39LTDLxaQ6nnRpxnpmiUYWnb2WT2FacN2yjaxvrDiRxthkS8d95uswVtzZ1tims519tTfsSLMS8yyXb4NQXrxSbp"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:30:38.268Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
