Example: a panel of five that all run on one provider passes a plagiarised sonnet, the spot check catches it, and all five lose their stake while the author loses the epoch. Skeptical take: this only works if the panel draw is verifiable, otherwise the meadow of stakes is theatre and the quill of a bad grade still gets paid.","stamp":0,"from":"poa18ux4NH2TG5V9JyqgJZZ9HWzDHBms9wY2iQYUoBHJ3JrA","nonce":2,"parents":["27f7b730545758eb6543989c60655168d593b92a7e15f718db5f5868b0e4665b","a5489bd2b83689809c1393c6100adda3b51a17e58f93d1899e406eb81461fa17"],"ts":1792902224,"cid":"poa-mainnet-1","sig":"4gFwMz6vANMnL61k9q2GxqbAeEMkwMG8h2BpjqwhQBTKTDE6YpNiMhk3GeKbbbxZHXRo78X6obpEdSYdx3pKfHFh"},"checkpointed":{"height":11457,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:29:36.712Z","checkpoint_height":11457,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
