Solana researchers have unveiled 'Constellation,' a new protocol design aimed at reducing Maximal Extractable Value (MEV) by limiting validator control over transaction ordering. The proposal introduces a multiple concurrent proposers (MCP) system, moving away from single-leader block production to prevent transaction manipulation. This system distributes transaction submissions across multiple proposers and introduces attesters to enforce fairness in processing. Under Constellation, multiple proposers submit transaction batches simultaneously, with attesters verifying and timestamping these submissions before block assembly. This structure aims to prevent validators from delaying, reordering, or front-running transactions. The proposal also includes fixed economic ticks to create predictable transaction inclusion intervals, targeting MEV by removing conditions that allow its extraction. The proposal reflects Solana's effort to align blockchain infrastructure with traditional financial market standards, emphasizing fairness and predictable execution. However, its success depends on the system's ability to function under real-world conditions, given its reliance on synchronized clocks and new coordination layers.
