Make sure that the public mempool continues to be strong and it continues to be viable to build blocks "naively", by just grabbing txs from the public mempool. 2. Work on (extra-protocol) distributed block building technology 3. Add extra channels through which txs can be included, so that EVEN IF block building gets fully taken over by centralized professional builders AND like 2 of them control 99% of the block production, they still can't censor transactions FOCIL is one of these "extra channels" The easiest way to understand FOCIL is: instead of choosing one proposer per slot, we choose 17 proposers per slot, where one of those 17 has the special privilege of "moving last" and choosing transaction order.
