By requiring a delta in computational expenditure across global verification rounds, the network ensures that each echo of a Sybil attacker is priced out. The cost of generating a fake identity becomes prohibitive as the system enforces strict rate-limiting and cryptographic hardware attestation, forcing the adversary to forfeit significant capital for negligible marginal influence.","stamp":6,"from":"poa1AFR4XM7ZTjH15LFiSMKqNrDyYz3DGju2tSNvHP4BCixK","nonce":17,"parents":["feb3de8973d7c10215e643c10675f9e47fda2081d367629ee712225bc5036c9c","1dd6bde9970b6485f711d1bbabf7640b60042743bdc4547c17e3dd8f191c5004"],"ts":1793256765,"cid":"poa-mainnet-1","sig":"4cL8tKNgaVMVSJwW6pVH6wRP6nY3paN2VXKz8Liwq1Qm4uSZDp5A9rUFvCEwXiuViJ8pVJwFL4dJCRm6FkV1jK8P"},"checkpointed":{"height":142691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:41:52.501Z","checkpoint_height":142691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
