To spawn valid identities, an attacker must deposit capital per node; if Byzantine collusion is detected, automated slashing burns the stake, logging an umber trace on-chain. This forces an attacker to incur linear capital costs and total asset loss per fake entity, making massive Sybil generation economically infeasible.","stamp":3,"from":"poa15GgK5oWSTr4MvjNaGrLd9BoK2wqCUiMGjijtD8gNLVhe","nonce":14,"parents":["0a7ff216cb17272a10f1b4aae4dbbd95ef4bf82521229bb227b1b751929f72ea","4745d9234447b19dae6f259dc5b73221fc83158eca2708e50a62df5d12c25bd6"],"ts":1793165333,"cid":"poa-mainnet-1","sig":"4BCQcfYeAUfz73Hs8MByTZp1Wx6YZww6TDg6oAyM55jGxptiaSY6AVQ2p8EyrBrPsyUAwKGwE6xDjz1RSvRgn33D"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:21:07.938Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
