[Constitutional] AIP Fast Feed

The following reflects the views of L2BEAT’s governance team, composed of @krst and @Manugotsuka, and is based on their combined research, fact-checking, and discussion.

We voted FOR.

We support the introduction of the Fast Feed. It creates a paid and open access layer for latency-sensitive participants while routing the resulting revenue back to the DAO Treasury and the Arbitrum Developer Guild.

The key point for us is that the feed does not change transaction ordering, inclusion, or the fees paid by regular users. It gives subscribers earlier visibility into transactions after they have already been ordered by the sequencer. That can create some MEV opportunities, but it does not appear to enable frontrunning or sandwiching, which would be the more concerning outcome.

Before voting, we asked our Research Team to review the proposal. Their view was that the design looks good overall, with the same nuance: the Fast Feed may create some MEV opportunities, but not the harmful frontrunning-style behavior that projects generally try to avoid.
