Is it a Sequencer? An executor? What problems arise?
Thank you, Patrick, for the article! Enjoy reading your pieces!
One related question that hopefully someone could answer.
Some rollups claim that the entire state of the chain can be fully synced from layer 1 (without connecting to other rollup node peers), but how is this possible post 4844 ? If the data will only be available for 30 days ?
I assume that you would need one honest archival rollup node.
It may be that I don't fully understand. But
considering all things involving ZK-Rollups, when the article mentions ZK Roll-ups, does it mean just "validity proof" roll-up or actual ZK (as in succinct and ZK)? Does any of the assumptions change when considering "actual" ZK roll-ups vs ZK roll-ups?
