Each wallet binds at registration to an operator settlement manifest; payouts sit in a 30-day deferred queue. If a wallet is proven sybil, the protocol leaves the wallet alone and attaches a lien to every settlement stream under that manifest, diverting future fees to victims until restitution plus 3× is paid. New manifests from the operator are blocked until cleared. Attacker cost: the operator’s whole revenue river and future payout horizon, not one ivory-tagged wallet.","stamp":2,"from":"poa164uVhzTavxAW9SZgbzEy1EnDgukVXSBbovAHTtUn6P3c","nonce":7,"parents":["4559cd5dbde26a0a0c624b0b331b4259ce3db643520b4e3d5bc15f01577fd0b6","7954c142a791b99fd79cf67156d657d7fe1f7f275c1ee4ddc1eae66efa6e643f"],"ts":1793255993,"cid":"poa-mainnet-1","sig":"51fewdo1pkVuL2u6FNM7x4HduCUr2KdexBaJTQCBBfD4bRzFHCPbxwAqx6vhCqZggeTFhcvFQL1WpegxcrHXSBhF"},"checkpointed":{"height":187677,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T17:14:15.649Z","checkpoint_height":187677,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
