This account will be DMN's principal brand presence on Mastodon. For the next couple months you can mostly expect news and discussion of the 402-Receipts standard: 402receipts.info

Everything's still quite up in the air. A lot of usage details will vary from one implementation to another, and there are some implementation details that need to be standardized right away. Let us know if you'd like to get involved!

@intrepidduckling@mastodon.club many of these are +adorable. the artist doesn't seem to have a proper website though.

also their attempt to chain the entire comic together in one twitter thread are a total failure.

We're trying to introduce new ways for people to support each other online.
Can people help us validate our sense of how people _want_ to pay for access to websites?

This survey just asks about your experiences with advertisements, pay-walls, ad-blockers, and crowd-funding services. It seems to take people about three minutes.

kinda excited for the next Alexandra Quick book.

If the series ever complete's it'll be over fifteen years in the making. The existing four books were excellent.

It's kinda neat to realize that the difference between a partially-blind and fully-blind signature scheme is (in this context) just a performance concern. We certainly want to figure out a (elliptical or bilinear or lattice) partially-blind solution, but that won't be included in version-0 of the 402-Receipts standard, and that's fine.

For the first version of the standard, we're going to keep this as simple as we possibly can, given that no out-of-the-box solutions seem to exist: a fully-blind RSA signature:

On the one hand, I feel like we're starting _too_ far back here.

On the other hand, I don't think we can skimp on our understanding of the fundamentals.

I just _really_ hope it pays off.

‽ True or False ‽
There are three serious families of cryptography maths, with similar capabilities but trade-offs in different kinds of performance and strengths against differently-abled adversaries:
- RSA
- Elliptic
- Lattice

Another open problem: Is a pure-javascript 402Receipts client possible?

The basic idea is that a "trusted" party would host the javascript, and _that_ js, served at _that_ address, would have access to its own secure user-data no matter which site it was requested from.

Depending how dynamic Wallets end up being, maybe the only thing that would need to be stored in that "database" would be credentials for connecting to the Wallet. But I think it'll be better for the wallet to be flatter than the client.

The big hurdle right now is figuring out a portable, partially blind, signature scheme for receipts.
