This is a good list of things the industry currently takes for granted that are worth re-examining. Many of them align with modularity: • Geographic decentralization is important -> rollups can take advantage of geographic centralization for extremely low latency • BFT consensus is a prerequisite -> sequencer preconfs are probably good enough finality for most users • Sharding is bad -> parallelizing execution by rollups enables massive scaling, interop is getting 10x better • All apps should be treated the same by the chain -> each app can be completely customized and vertically integrated as a rollup Many of these ideas will be tested by Celestia and its ecosystem over the coming few years.
