Assalamualaikum,

Dear friend, You have mentioned all the main problems raising in Blockchain technology and you have said right that scability is a major concern. It is hard to maintain large data and at different places.

The features you told us amazing but i like the most which you written about the Transparency of Blockchain. Every one can see the record on Blockchain which is very important thing for Blockchain and in this way corruption can be stopped.

You work hard to prepare a slide to show how Blockchain operates, you have done a quite impressive job to write this post. Like the all time you have written easy understandable post.

I always get information from your post. My words can't appreciate your work but i try my best to reward your hard work.
