This blog post is all about this paper by David Wagner from 2002.
This blog is in the category of "a new-ish idea about privacy tech"; like similar previous ones (e.g.: CoinJoinXT) it is little more than an idea, in this case I believe it is correct, but (a) I could be wrong and there could be a flaw in the thinking and (b) it's not entirely clear how practically realistic it will be. What I do hope, however, is that the kernel of this idea is useful, perhaps in Layer 2 tech or in something I haven't even thought about.
The idea of a ring signature (the term itself is a bit sloppy in context, but let's stick with it for now) is simple enough:
How sure are you that the cryptography underlying Bitcoin is secure? With regard to one future development of Bitcoin's crypto, in discussions in public fora, I have more than once confidently asserted "well, but the Schnorr signature has a security reduction to ECDLP". Three comments on that before we begin:
This post was mostly prompted by a long series of discussions had online and in person with many people, including in particular Adam Back and Tim Ruffing (but lots of others!) - and certainly not restricted to discussions I took part in - about the tradeoffs in a version of Bitcoin that does actually use Confidential Transactions.
