Re: way to sign/verify to prove ownership of an address without revealing it?

So what you are looking to do is:

Text:

Code:

This is DaveF saying this

Signature:

Code:

IGd595fz/NXdZJSV0DDA4grRZAf4kDqBB7fa8LnI7wuIf7Ihu8chopvTsWWXGieVFqysnZ3laZZzAJ0Enw5x8cc=

BUT not tell people what address it's signed with.

So, until there is a NEED to prove you wrote something there is no way to know if it's valid or not.

So in theory 10 years from now I could prove that on 4-Feb-2024 because of the above text and signature I controlled the address bc1qugdlj4sghspzyx5w74xm77mn67auyzc2y6huls

I cannot see another need other than that.

Yes that is what I was trying to explain I was trying to do. If the document is public, this allows people to view it, but I can selectively prove the ownership to parties I want to do that with. Sounds like a 2nd hashing is a good way to do this.
