The exploration of Maximal Extractable Value (MEV) protection on Directed Acyclic Graphs (DAGs) integrates Blind Order-Fairness to prevent transaction manipulation by malicious actors. MEV exploits involve reordering or injecting transactions for profit, leading to issues like network congestion and increased blockchain costs. The text outlines different techniques to implement Blind Order-Fairness within Byzantine Fault Tolerant (BFT) consensus protocols, focusing on keeping transaction details hidden until a commit order is established. These techniques include threshold cryptography, verifiable secret-sharing (VSS), AVID-M, and a Hybrid approach, each offering varying levels of complexity, setup requirements, and communication demands. Within a DAG-based consensus framework, validators use a broadcast and delivery system to ensure reliable and causally ordered transaction processing, which simplifies the implementation of Blind Order-Fairness. Fino, a proposed protocol, demonstrates how this can be achieved with minimal latency and complexity, ensuring transactions are securely committed and opened in a DAG without compromising consensus stability.
