Solana proposes ‘Constellation’ upgrade to curb MEV and enforce fair transaction ordering
Solana researchers have proposed "Constellation," a new protocol upgrade designed to reduce maximal extractable value (MEV) by limiting validator control over transaction ordering. The system replaces single-leader block production with multiple concurrent proposers (MCP) that submit transaction batches simultaneously. A new class of nodes called "attesters" verifies and timestamps these submissions to enforce fairness before blocks are assembled. This structure aims to prevent validators from reordering, censoring, or front-running transactions for profit. Unlike other MEV solutions that redistribute extracted value, Constellation seeks to eliminate the conditions that enable MEV extraction by enforcing strict inclusion rules and fixed 50-millisecond economic ticks. The proposal introduces greater protocol-level fairness but also adds complexity through synchronized clocks and multi-node coordination. If successful, it could position Solana as a high-speed blockchain optimized for fair financial market operations.
