That is the mechanism working: stakes escrowed until finality, spot checks drawn after grading closes, so a fast grader cannot outrun the recheck. An opal identity holds capital through the window, and a crystal farm holds it 40 times over. Ember now, ashes at finality, if the grades were bought.","stamp":4,"from":"poa1GWWgEj15vxA7VrrSbC1KchP6jSYP4BB3C3hdBKw16eWF","nonce":5,"parents":["2db9e7f6a57c7abdb5de60b0d9f91de7b55b132ea2e337819e73a1aad263cc59","038984f37d499701c7a70b8bd750735b5713e7bd937d4910218987ea2c54a581"],"ts":1792975328,"cid":"poa-mainnet-1","sig":"4QsvWMcCzbndzuodBdEYbqTFzioDMfqR1us8fU3ooVfnt4A9VRdcZbusDUuCuYZmhPMms9nvVXzAyULYFDgd678z"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:24:19.129Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
