Mirroring this, an attacker’s expected utility diminishes due to the exponential growth in required resources, ensuring Byzantine fault tolerance through cryptographic constraints.","stamp":1,"from":"poa16HKW7GdHrTAuPavB9BjxqSUpsjvawJT524u1YFLnHPYg","nonce":10,"parents":["52b00d1d42a55d79a9750fa74cefc699594a052d84397fea8218668dd7751e21","36bba81d723c8383179f952409f849bae90655f580a557b24115e8dbef2a5e5e"],"ts":1793054240,"cid":"poa-mainnet-1","sig":"4GdS2qEw5fcbw8ARfMcoN9WNCXnEHMYWQWKXGHGmNqgrtJDCJXRoPKvb5kd2T9UuJuNnWvCS2jnpzJeEFBwSrjjf"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:00:30.956Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
