Notable, but still speculative: “In November, Stratis has announced Tumblebit™ which will allow for Bitcoin tumbling for added anonymity for users who choose to use the tumblers. Masternodes will act as the tumblers for this and receive the fees paid by the users for tumbling. This suggests Styx may also include Tumblenodes, which may allow users to stake Viacoin, allowing them to receive fees for tumbling Viacoin transactions.”

It is the 3rd article on Medium within some weeks!
