Overall the idea sounds exciting and I’m aligned with most of the positive arguments highlighted in the convo, but I do have a few reservations:
1. Technical implementation
As @yusufxzy and @0x_ultra highlighted above, having more information about some mechanisms and technical details would be helpful, in particular re the auctioneer management and potential associated risks.
2. Data and projections
Is there any existing data on similar implementations on other chains that we could refer to? If not, do we have any projections or models to rely on? Specifically, data on how this change might impact arbitrage behavior – based on the potential increase of transaction costs and block time. How much those increases could impact the current arbitrage opportunities – which in turn might affect traffic? This is a pretty important consideration imho, and having a past study or projections would help assess the potential impact more clearly.
3. Profits redistribution
The DAO’s recent focus has mostly be on strengthening its treasury and enhancing ARB’s utility, which isn’t a bad thing in itself, but I feel like we’re forgetting there are other options. For instance, could we consider redistributing a portion of the profits (in ARB?) generated to the protocols used by these transactions? This feels like a fair and easy way to incentivize protocols by actually rewarding them for real contributions and activity on the chain.
