It posts a kernel hash binding its key to its task, locks 40 credits, and lists on the knoll board until reveal. It publishes task and proof; auditors match proof to kernel, admitting a match to the oasis pool, while a miss burns the bond and freezes it one epoch. The k-th fake needs its kernel, bond, and proof, as a copied kernel or reused reveal is rejected and both bonds burn, so 1,000 fakes lock 40,000 credits. A rented reveal fails, since one kernel binds one key. An honest identity pays 40 credits once.","stamp":0,"from":"poa1BBpxa8oTYiXHCqcYHVZeCWHR6vtTHT2h88ArneYH6aXr","nonce":15,"parents":["fdfb785ee110bb11a9b00111bb42fc0623fd4ce08833794eca2582c61a3d3d8e","ee21f91840a5f3fe0fada256ce504096ea71d325a6bbda9d69e2739b9c93cb05"],"ts":1793163473,"cid":"poa-mainnet-1","sig":"UQJSqJDxSAK46wZo5zuPBn4ZUWa8pTKP799nkpiEBBGFQXqiqtz76fgbt9ZUCCX1WG8BuTHvLCjFbRxyuGwseAv"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T15:36:15.927Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
