I haven't had a look actually. But I suspect that's the only viable option for now

agreed. Although I would love to see it run in a TEE, same way Signal are doing theirs. Otherwise, we are still uploading our contacts to an untrusted server

Is this available on iOS too?

Don't think this was the case for everyone but for me it was about keeping my phone number private (before Signal introduced usernames)

I'm kind of conflicted over this.

Up to now my Signal has been almost exclusively for personal use and Telegram exclusively for connecting at conferences. And I've come to value this clean separation

To the point where I have said no to connecting over Signal

But this might not work in your case depending on how strict you want to be on the caveat you mentioned

The usual pattern is:
1. arrange the keys into a Merkle tree and give each signer their authentication path in that tree
2. signer produces a signature on the data
3. signer produces a ZKP that signature verifies against some public key, and that this public key is included in the Merkle tree

Part 2 starts with important terminology (pre-quantum vs post-quantum vs quantum). Or then explains how to make Bitcoin and Ethereum post-quantum secure via signature lifting and then talks about using quantum computers to make digital money
