Mischa said that the next article about rwpos is being prepared,
I think next month we will read, after that a white paper is expected. The testnet will begin in 2019.
A promising project, time is needed, it all depends on the developers and the market
These things take time to prepare even if they seems trivial.
I suppose once we will get the whitepaper everyone will have a clear idea about the future of Sirius, beside 2019 is really just around the corner and we may be able to test something they are working on. So i'm moderately optimistic
