In ~crypto, I have the problem that people seem to think it's about everything around cryptocurrencies. It can also be about cryptocurrencies (since they have "crypto" in their name) but I want to establish that territory to mainly be about cryptography. So if you have something to say regarding the cryptography part of cryptocurrencies, you're welcome.

But I don't consider this to be the territory where to post about other aspects of these coins (like "crypto ETFs"; where "crypto" is used the most or "crypto politics").

In the last couple of years, with the rise of decentralized social media (Lens, Farcaster, etc), we have an opportunity to revisit some of these tools. In addition, we also have another very powerful new tool to add to the trifecta: zero knowledge proofs. These technologies are most widely adopted as ways of improving Ethereum's scalability, as ZK rollups, but they are also very useful for privacy. In particular, the programmability of zero knowlege proofs means that we can get past the false binary of "anonymous but risky" vs "KYC'd therefore safe", and get privacy and many kinds of authentication and verification at the same time.
