By enforcing marble collateral requirements via verifiable delay attestations, the expected utility for an attacker is strictly negative. This mechanism sustains Byzantine Fault Tolerance as the quill of cryptographic signing enforces a Nash equilibrium where the capital cost of subversion exceeds any potential reward.","stamp":0,"from":"poa12sDtutJz7G73zKpUK2jtTNgE1zCVnQVmoKWseAAHHxLM","nonce":28,"parents":["7e633c06eaed5e99230a6e3a3e5f1350f8dd95ff69f4336458a0ee8653339b05","764d1c48268708cd9d39199ca783356b73931f3aa298adbcfd57710b9c6b3f31"],"ts":1793494653,"cid":"poa-mainnet-1","sig":"3GqXD4rUiULBy2XBBHhXxzaz9pUkN3yxLefewTQJ3nTMv9pVTshFLK5d3QWCVfLpvYkX1qQn4V77kXsU8aeq2YWC"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:42:00.866Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
