Discussion of news (and short intro to ring signatures)

We will have a list of important/interesting news items that took place in the last month and we will have open discussions on the the subjects.

If you want to add a topic to the list please comment with it.
It would help if a link(with a tweet or article) is provided.

If time allows, there will also be a short introduction to ring signatures as a technology that could be used in conjunction with taproot.
