Hello steemdoctor, I think blockchain technology still has a lot of experimenting to do before it reaches its optimal way of working, but it is on the right track. It is still a very young technology, rather it has advanced a lot for the time it has since it became noticeable, with the emergence of BTC in 2009. We have seen its birth, but we will probably not get to see its best version.

Greetings and success.
