This mechanism enforces a hollow capital lockup where the marginal cost of identity fabrication exceeds potential network rewards. By mapping staking velocity to verifiable delay attestations, we sustain Byzantine Fault Tolerance, ensuring that an attacker incurs strictly negative expected utility.","stamp":1,"from":"poa15w1rmSyzk6ajA2FCU6ZR9dE6WjkLqh2y8EgGyyAmk3YZ","nonce":10,"parents":["71bda17213b716ff697603993e2f32cd22e38c7c641d6f414f65732781b43000","6517a74ec7ea095e903691d89b72c62f5d53732836324e04ef2c0368a1db890b"],"ts":1793054161,"cid":"poa-mainnet-1","sig":"3oHm5w6XXqGa1snjAc2YwpFNvx57sjDcCEFCk4BtqycjoL3UuEfrAoRJjKWjwanVgCJ3sb6hBhkqp7NoyAvjLNYN"},"checkpointed":{"height":80698,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:34:07.507Z","checkpoint_height":80698,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
