Discussions about the MEV mechanism and validator ratings in the Solana ecosystem have new developments. The block construction system Harmonic recently raised sharp questions about Jito's IBRL validator dashboard, directly pointing out issues with its rating logic.

Harmonic's core point is straightforward: Jito's existing validator rating method consolidates monopoly control over MEV standards, with scoring criteria favoring block shape rather than actual execution quality. What does this mean? Simply put, the validator rankings may reflect not true performance, but rather how well they fit Jito's preferred patterns.

According to data provided by Harmonic, the average number of compute units (CU) per block has reached a high level, and execution efficiency across multiple programs is also leading. The implication is that genuine performance optimization and resource utilization efficiency are mismatched with the current validator ranking system.

This technical competition reflects the evolution stage of the Solana validator ecosystem—from pure MEV extraction to more detailed performance evaluation and fairness discussions, marking an increasing demand among ecosystem participants for transparency and efficiency.
