Some assorted thoughts on Vitalik's latest post by MetaMask co-founder Dan Finlay. Preamble Thanks for sharing this vision of the decentralized future. This seems like a nice opportunity to share some thoughts, and a sense of how MetaMask is building towards enabling all of the solutions listed in this blog post and more. A number of the approaches listed in this article are things I completely agree with and we already have initiatives underway to address (privacy is mandatory, wallets should sync data, wallets need to seamlessly integrate L2s, cross-chain applications should be feasible, users shouldn't have to think about addresses), and some of the proposals are a bit more technically ambitious and seem to deserve deeper consideration (the keystore contract proposal). That said, I am happy to say that even the most ambitious proposals here fit well within the current MetaMask roadmap, and I'm happy to now do a review of how.
