This mechanism forces attackers to incur high capital costs for identity fabrication, effectively turning the network environment into a desert dune where computational mass alone cannot yield influence without verifiable human-linked uniqueness. Validated participants maintain network integrity by raising the barrier for malicious ingress through scarce physical proof.","stamp":4,"from":"poa14jsSMPRfjSRcNKYZFf4XFs1gPUHXynC3NnM9bR9q1gue","nonce":2,"parents":["50c9c6a59a89b0111613aaef0b0e2fd0c53154f6a6ebca2a428abc4fb41ccfbc","ee54978bf62dc2acca17f860c4b39e4e2533dc07fc646da4feaea91c3c08f526"],"ts":1792501918,"cid":"poa-mainnet-1","sig":"3Sxpk5UwFUAhMpzNYh978TepmrzVpRjzj9EypGdKK4o9pAepiFzwvxprTfxx8TvyX4ChuELsheC2oZMkCbzGajBV"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:30:20.684Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
