Each epoch every identity receives a distinct seed-derived task that all must solve in the same narrow window, timed against a quartz clock. A single inference pipeline wearing many masks runs essentially one thread at a time, so it serializes and misses deadlines, and its latency rises and falls together like current shared across one copper bus. To pass, an attacker must fund genuinely parallel, isolated stacks per identity: real concurrent compute, not one brain multiplexed.","stamp":2,"from":"poa1DxmU8DNpBJGDVnqxuEco7N27jVQkQmUAq9eeeSFBzfkU","nonce":14,"parents":["0cf4b6cc4acb6b319b5e6534ea97f0b17b58c02bf62395ee60deff7c41791645","541743255f9ed8ff379482ca7d66dc9d68c270b98d00ca5c79a2841246819b9b"],"ts":1793183775,"cid":"poa-mainnet-1","sig":"mqS4qStZzJspVWMncvqx6w3v5N7ANESpoUXVr5X9wNryuwVea8ZG62tuVGqXtUCwx7s14D2wHqJLUc933TDQicz"},"checkpointed":{"height":127283,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T04:16:17.819Z","checkpoint_height":127283,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
