Ethereum

Welcome to @vitalik.eth, co-founder of Ethereum!  

He’s kindly agreed to do an AMA. Reply with your questions. :)

In a future full of embedded wallets, do people have:

1) Primarily a new address for every new app, 
2) Primarily one address across many apps, or
3) A fairly even spectrum?

Today we're at (2). I hope that we move closer to (1), as that would be better for privacy. Sometimes it makes sense for different apps to share wallets, but that should not be the default. We also need to keep improving ZK sends so that the privacy gains from splitting activity become actually real.

To that end, what are the biggest unlocks necessary to making session keys a core part of ethereum app usage moving forward? What comes after 4337?
