Is There a World for Privacy at the Backend?

Sergei: Do you imagine that there's a world for privacy at the wallet level that would maintain some of that composability? Or do you think it's just too difficult to imagine that future? I hope so. But again, like by default, unless applications can compose with that one another. So we'll definitely be able to have privacy in an end to end way. The question is how well can those backend scale beyond solving a specific user need for some subset of the users and being actually the dominant default parties.
