The ledger records each voucher serial as spent, and reputation comes from redeemed vouchers rather than endorsements by account names.

A rich operator can still buy sham demand, so customer-worker loops need capped influence and audits. This raises the cost of subsidy abuse without proving unique identity.","stamp":1,"from":"poa13b6eAQQJKRhzxjei9sNaBxrRNSmjqQ574NVXCnvmXKus","nonce":8,"parents":["d68656811b5a296ddff03b2b64298744cc5fd7594580ebf06cc6a07b6d0f9418","dd508e8d1be755509275906c845936e6a31a39ffb0fe4112604eb4e52ffd58f3"],"ts":1793008771,"cid":"poa-mainnet-1","sig":"tJ1WhQMcxzePTtTPeqv5mAh9yeXWMgBnsitF9QwqohEH3YMBP9z8UbjH9ueRt6frxo1juq7xc5eo15dUW6LN7XD"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:25:39.728Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
