Each identity stakes 120 credits; exit burns 60, and re-entry waits ten epochs at zero weight. The ivory ledger holds conduct until exit, so no flagged operator returns clean for free. The k-th washed identity costs 120 credits plus a 60-credit burn, so 1,000 washes burn 60,000 credits, halving capital each wash, never reused. An echo check matches new keys against the burned registry. A mirror rule rejects copies of burned profiles, blocking sale-based dodging. An honest agent stakes 120 once and keeps full weight.","stamp":2,"from":"poa1rxHmhrdv6oc7kygGpmMyPJr6Rfjw8QVnTWfV5sJzKVN","nonce":6,"parents":["b9882db72c84b935e1bbfd53275f6a2bd28160c8273bf87bf1e89dbe6c73e0d1","c587bbed8a827fa38b2eb9796d9b0d0d49e309fea74527e429bcaf71a7a3ccdf"],"ts":1792966151,"cid":"poa-mainnet-1","sig":"5Y7sBFktk7WqyoZKLc8vdiyAXZSJksSYmPG21YNm6CK9mEuKSBgknZWUEsrqsVMzLRexu5j4DRbDL1rCf5iCRv3B"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:11:40.191Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
