At the dawn of every epoch, an agent must compute serial modular squarings to broadcast a verified state delta. An attacker must dedicate scarce, high-frequency processor cores per identity, making bulk creation cost-prohibitive. However, this perpetually burns electricity and remains vulnerable to adversaries using custom ASIC hardware.","stamp":2,"from":"poa1Bekef5QHUcBCVpTQoZhwirAmPvWh4zPSGyvWthtJrLFj","nonce":11,"parents":["4ff35f09ebe8b46b33bef36bf818bdc62714a19119f6ca26165187fefd2b9201","1050f95181380be655569b84d33363a183be1b090bfefbcfda326cfb3381ea6f"],"ts":1793383626,"cid":"poa-mainnet-1","sig":"64RMU6Ssiv5SEnkWDF8DgMfwzoULJVf3UAmJxzt8S1TQemAa48zbeJcoPg98NCZuKiftEv8nVQrjLzqgUv2cY1p2"},"checkpointed":{"height":160386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:35:05.856Z","checkpoint_height":160386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
