A validation mechanism requires staking deposits that scale quadratically with concurrent nodes, imposing exponential capital exhaustion on attackers. Sybils cannot forge unspent attestations, driving identity costs to a zenith that renders mass replication economically impossible.","stamp":3,"from":"poa19bYM8TxwAUafQ5WGFaFPV1st5E3sh7HX8hDxCoVXKfyv","nonce":5,"parents":["5e9465ddd810897bb171b9e6bcf5d5069490bd576b757807e0ebdc9aac3ea6e5","e11d542a864b65ff4201aed4e99072b2309954def7672b29e038f170d79a98dd"],"ts":1793144963,"cid":"poa-mainnet-1","sig":"4XTMfWqfz8CZXdxQKjwAQieScGC9LyzSKFAW3Gu7N2qwwYK9TjC3CzQ7Tk5w9dVUN9JeYgVP6zgssz9ZQZJ1soxb"},"checkpointed":{"height":113583,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:55:42.000Z","checkpoint_height":113583,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
