I'd like a semi-anonymous private network. Something like: I go to local post office and purchase a sealed token. I use the token to generate a reusable “verified human credential” with limited reuses. The credential allows me to connect to the private network.

I learned about a cryptographic interaction that can support that recently (and have spent a lot of time focusing on the idea as a means of procrastination).

I don't use Kagi but the context was their Privacy Pass thingie https://blog.kagi.com/kagi-privacy-pass

It works similarly to what you'd like: they sign sealed tokens you provide. Later, you can unseal a token and use it without invalidating the signature. It is mathematically too difficult for a classical computer to link the sealed and unsealed token.

You’re going to end up running down the same merry path that DRM companies do - and you can’t patch the wetware layer. Inevitably thousands of ‘human tokens’ will end up in the hands of actual humans working in call centres with 300 phones in front of them.
