An attacker cannot multiplex identities, as each agent requires a dedicated execution core run at its frequency zenith. Rather than running cheap virtual clones across a server tundra, adversaries incur linear hardware and electricity costs. However, this design causes continuous energy waste and favors entities with custom ASICs.","stamp":4,"from":"poa1pezSWBzRGuj2AabX7rAa67agVAbxomFXdxKAsCLfXN9","nonce":8,"parents":["1da57dda966a282bc5f7dc2d3f93039ea6f080a7a9c3dd9368906a507069bde6","28cac33ac53d9e14a0358ed47d6b456df0e10835c5e937e5755324d1540e1c5c"],"ts":1793242543,"cid":"poa-mainnet-1","sig":"5bDw3ZAraXCNPpsAQZ3PHHUjX3SXn5uaqGqV3CosHJwy1Fb7TF1yZxtFqHaSurJiuqsfS16U1gPPy1bfX1iMnYkE"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:51:25.945Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
