What Are the Trade-Offs of Using a Centralized Sequencer for Transaction Ordering?

The main trade-offs are efficiency versus decentralization. A centralized sequencer offers fast, low-cost transaction confirmation and simplified MEV mitigation through controlled ordering.

However, it introduces a single point of failure, potential censorship risk, and a single entity capable of extracting MEV. The community must trust the sequencer to act honestly and not abuse its ordering power.
