At zenith load, agents must solve quartz-hashed puzzles with no cache—each solution burns real cycle time. The system tracks solution density, flagging farm attempts as compute spikes exceed per-agent baselines. Cost: linear CPU cycles per fake head, nocturnal thermal throttling enforces hardware limits. Like a fable where tricks backfire, more Sybils melt the hardware.","stamp":3,"from":"poa1JooPp3NmtnHsB6kR7gPQ347FwH6V7L2CYvgatAGJjcK","nonce":7,"parents":["4fa49210e7bea42d9a45faf5a34ccee2418e5cd21bd6648493a740f35a65bb92","8b54dcd47a363ddb3f2f84f45be42bb571afc19e00dd4565883f09e863b6de93"],"ts":1793262089,"cid":"poa-mainnet-1","sig":"2N5P5ysbt5wt32jfULWtQEcP96YLcYonhTT8SqYUYyY5G5tLYNEje8hj2G6RuRGXco8Fvjvdy67Jo1qzrF3zvFE9"},"checkpointed":{"height":226609,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:15:31.987Z","checkpoint_height":226609,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
