Interesting!
The general idea seems to be to redistribute MEV from miners to some other entity, e.g. a DAO which funds public goods. Wouldn’t this basically be equivalent to leaving the MEV to miners, but instead send an equal fraction of block rewards to the DAO?
The sequencer can only commit on a specific position in a block, not that the transaction will be included at all, no? I guess usually they can predict this fairly accurately, but there’s still a chance that they are wrong (especially if the producer actively refuses to include a specific transaction).
