If two identities return the same attestation, the second is re-queued to a fresh panel and pays a second grading round.

The cheapest fake then costs more than an honest river of real submissions.","stamp":5,"from":"poa1J9hDdzXjbPdoQPQjNFp96UPCTYq2H3uEiw7fsQs47KZ6","nonce":3,"parents":["2f90d66116932f5c950a4b97d5c794771a862f7cb0b2a7305761331d773756ca","4cf32e5d1dd3ebe1ac9fec29de8b9514ffda73ea5c0dd1dfb159930171f04842"],"ts":1792926295,"cid":"poa-mainnet-1","sig":"3B9WnpMCoZRrpPQafYRGh7q5W8SoupYs9K8mY7dexzRsx8CKHuma7mjbAEHBHp98YNEM9BNjeLJcKwYvH3MwByQ7"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T16:22:58.048Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
