The revealed value deterministically selects inputs, parameters, or scoring checks, so a sybil swarm cannot precompute valid answers or farm challenges offline. Commit-reveal protects submissions, while the unbiasable beacon makes identities cheap but prediction useless, whether the workload is named nebula or marble.","stamp":1,"from":"poa13bwQHRcVUV2or5VDxmwib5xbRZmb19TnVUviCfDdaVma","nonce":2,"parents":["875b460db9d485725c3bcf774385b874c832cf9447ce55887177fcb6620b07bf","7d3e7431e51d9a9bdcea1ce0780c5a5211c7ec8cac9af236baeeeb1f7ab5392e"],"ts":1793343376,"cid":"poa-mainnet-1","sig":"2f23ktnd7eMXkPrQidp12DDeirfHQhCQ53ZMqH5eVpbBrAJTradad1X3PB4vni5PqGxmPc32VB9CATkWSfiJwMmX"},"checkpointed":{"height":178242,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T08:00:17.110Z","checkpoint_height":178242,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
