ZKP2P is a super fascinating project.

In my reading, it is the first project to incentivize private data ownership with money. Specifically, by being a Venmo LP and making ZK proofs of Venmo emails, you can collect a % fee for the service you’re providing of on-ramping people to the chain. And this is only possible because you have VIP data in the form of DKIM signatures on your venmo emails!
