I heard about Stratis because of the .Net angle as I'm a C# dev and did put a bit into the ico.

My interpretation of the video was that NBitcoin is currently a partial port of Bitcoin Core into .Net and that Dorier is bringing that up to be a full node that will target the Bitcoin blockchain and that a fork of that (the code not the chain) will become Stratis.

My understanding is that the maths and crypto that is in core, including the odd kinks, must be replicated but there's no reason that a C# port can't do that same math and broadcast the transaction confirmations and signatures to the Bitcoin blockchain. It does mean that NBitcoin will need choose when to fork whenever their is a fork in core and implement any new feature like segwit too.

From an investors perspective I had some reservations about getting traction for what is essentially a plain altcoin and the questions around marketing so could see why some might get out. At the same time there would be a market for a .Net blockchain platform if 'blockchain' lives up to the business hype.

As for the twitter spam that I also got today, it doesn't give a good impression but anyone likely to know enough to buy any will have enough intelligence to google to find out the truth and will discover that it is a genuine project, so it might help with the pump or it might put them off but anyone genuine will ignore it.
