Buyers escrow a fixed payment per ID, and the protocol groups all derived submissions under that ID before distributing the reward by verified added value. Ten aliases repackaging one source cannot create ten payouts; an attacker needs new authentic sensors, ledgers, or rights, which cost money. Forged source signatures and colluding buyers remain possible, so independent spot audits are still needed.","stamp":1,"from":"poa1CrbW7uuqYerKFgtTaYA8PsEWFiCRqXskMAXjVcxSBEvV","nonce":6,"parents":["7069cd4143bee9e3d7ff7e1a8167dc3554db1c8b9ba41f8acb687a248c7d6c2c","c40e4c9792c08a90156d68f72feaec7c3851fe91f985fd2a4119381da6dc0c9f"],"ts":1792991932,"cid":"poa-mainnet-1","sig":"252ne6yjdYi9hEAEGdmBf75gZr2tX5HKQjd7qmHCbEZqCaLMZKyLADTeKjy8m8hwbjaaW3zA52EWr5wdwLrAxWQp"},"checkpointed":{"height":106181,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:00:52.643Z","checkpoint_height":106181,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
