Deniability

[cryptal]

I've just learned about Deniability via Eric Wall's post. It seems relatively simple to implement but I'm far from a crypto expert.

“Deniability” is a very simple and very old idea, that many people bring up from time to time. It does nothing “new”, it is merely a collection of “wallet-side” tools to make the shuffling process easier (ie, less labor-intensive, and with less potential for error).

I believe that it is profoundly under-appreciated. It is very effective and very easy, and painless to implement.

If so easy and useful, why don’t have it already?

Well, it is probably due to two stigmas: [1] the sigma of “wasting” block space4; and [2] the stigma of working on a privacy technology that is non-mathematically impressive and ostensibly uncreative.

Can Wasabi Wallet consider implementing this feature in addition to CoinJoin? From what I understand, deniability doesn't require other users, and it would be faster.

It's an interesting idea and I think it's worth exploring. After first read, I'm afraid its benefits aren't substantial enough to survive a high-fee environment, which we're inevitably heading towards, but I wouldn't write it down just yet.
