This is from Stratis Whitepaper:
This broader application was developed by a number of ‘2.0’ platforms including Nxt and BitShares, amongst others. To date, however, all of these have been relatively limited in one way or another, and lack suitability in their current forms for adoption by real-world financial businesse.
How can we compare Stratis with NXT or BitShares? They both have their own coding, but Stratis is simply clone of a Bitcoin code.
One more point from Stratis Whitepaper:Stratis: key features
Stratis allows the creation of distinct, private blockchains, launched by third party organisations and tailored to their needs but secured on the main Stratis blockchain. They can be accessed via lite clients and simple but powerful APIs. Because these Private chains are based upon the code of the main Stratis chain and side chains are compatible and transfer between the two is straightforward.
With Bitcoin Clone, how Stratis can able to create Child/Private chains?
The Stratis full node and development platform will be built on top of the NBitcoin framework.
Microsoft and IBM's blockchain offerings will be centralised. Neither offer the only full node development framework in C# and .NET. Also, neither company will be providing consultancy for their solution offerings.
Nicolas Dorier has been developing NBitcoin since May 2014. He has made 1280 commits in this time and NBitcoin is a near complete alternative to Bitcoin core. It is also the only cross platform alternative and I believe at this time its the only implementation of Segwit outside of Bitcoin core.
Nicolas is developing our full node framework which is 90% of the work required for the Stratis blockchain.
