## Sequencer Centralization Risk

Sequencer centralization risk occurs when a single entity or a small group controls the ordering of transactions within a rollup or sidechain. Since the sequencer determines the order of trades, they have the potential to engage in front-running or sandwich attacks against users.

This is particularly damaging in options trading and derivatives, where order execution timing is critical to profit and loss. If the sequencer is centralized, they can manipulate the order flow to benefit their own trading activities at the expense of others.

Even if the rollup itself is secure, the user experience can be severely compromised by this extraction of value. Mitigation strategies include implementing decentralized sequencers, using threshold encryption, or creating fair ordering protocols.

This remains one of the most significant hurdles in scaling trustless financial infrastructure.
