It's been quite a few days I'm wondering if a Ring Signature Scheme (like Monero (XMR) has) can be implemented on Ethereum blockchains.
As far as I know, that will be so nice in order to increase anonymity (but understanding that it won't be totally anonymous because the signs will be done by groups ob Pub. Key Hashes, not all of them (which will make it totally anonymous).
As I see it, the PoW -> PoS pass will be a nice moment to implement that kind of changes.
If someone knows any paper/article related with that, fill free to share please.
