Ethereum

Beam Chain is basically the "zkEthereum" endgame I hoped for and wrote about in 2021, that plus the data layer and zkEVM upgrades. Back then, I had expected something like "about a decade", albeit delivered incrementally. So, anything sooner than early 2030s sounds like a win for Ethereum's Endgame. The one thing I'd like to see is what I called an "Enshrined zkEVM bridge" (a standardized in-protocol bridge for all "Type 0" zkEVM rollups) though maybe that's more suited for the EL, idk

My armchair showerthought is some of those upgrades should be delivered incrementally, sooner, like SSF, though I'm out of touch
