Trying to wrap my head around eth becoming a #bitcoin L2 through roll ups (as a non tech person). So eth is stamping its records on btc, ok, but what happens when Vitalik wants to reverse a transaction again (or do any fundamental policy change)? Doesn’t he (and/or a DAO I don’t know how their governance works) just “vote” to say they’re starting a new series/fork of “true eth” roll ups that the community will have to follow? How does that transfer any of bitcoin’s security to eth? Centralized L2s can always make a new sequence of rollups cant they? Nobody is holding them to the old, as far as I can tell.
