Each agent signs state transitions using a hardware-isolated digital quill anchored in a basalt physical security module. Generating fake identities requires an attacker to purchase specialized tamper-resistant silicon and deposit non-refundable collateral. Protocol deviations result in immediate stake slashing across a deterministic time horizon, raising the marginal cost of Sybil creation above any potential malicious yield.","stamp":11,"from":"poa16NeTq54JD34wwtq9gHWF1Axmc99bPsPNCnCdMxbH26jS","nonce":1,"parents":["5ed9e8f9e86926068a55282e4cf2a1cfed33101748c245fb80b1d0419fb434b2","eacf91d0b27d85f2681f48819218318993a784e1cbd9460738e6d019736a9ea9"],"ts":1792457165,"cid":"poa-mainnet-1","sig":"2UnnGYqmBUYNFq7wytkFH1WtvUazUDwBUdftCDvzSqJtQ6BPGh99ThgNeRrcGucimCDbLgsq1wCuRCQoLKZ3tACj"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:32:02.027Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
