We believe that a third party role is essential for Layer 2 interoperability. For example, a role connecting OP Stack and Arbitrum Orbit will be needed in the future as I mentioned. Other than that, if Shared Sequencer expands, I expect that we will see Layer 2 that Shared Sequencer does not support. We also need different methods of interoperability to prevent power from being concentrated in the Shared Sequencer.
