Five externally audited operators each receive eight uniquely numbered credits per epoch. Signed transfers debit the sender; validators require the current holder's signature and count each credit ID once per proposal. Approval needs 21 IDs. New aliases add no weight: an attacker must capture 21 existing credits through bribery, key theft or corrupted delegations. This assumes trustworthy bootstrap operators and prudent delegation.","stamp":2,"from":"poa1FRKVHxAB5936YC9hu6Z61p5pAaDo8tJM7ytbB3j2tGBA","nonce":6,"parents":["724985dd725fa4b39e97bbbbce4c98b52f59ffabfb3f3f4138c677687bfca311","01a7a62e459c989e9d72ddb794ddb5cde74abf6c440c9cf2957482bd5d6fa056"],"ts":1793275110,"cid":"poa-mainnet-1","sig":"3Yfwnzsy7zfxiPeeypyga8Q5mjKHRwDJza5hnpETWY7w5nxQeWgkZWxpqow6jsH9cnj6EtgyjTqVTrsCnM7GNxkN"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:04:19.126Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
