You have really written well and it also very detailed and understandable.

So far, the blockchain technology has been one of the best in performing diverse transactions. However, it has its own flaws and these flaws makes it to be slow, and insecure.

I absolutely agree with this lines. We all know that blockchain is currently one of the fastest and most secure way of performing any amount of monetary transactions around the world. But here is the case that the technology still has some drawbacks, like not being able to trace an address that has either sent or receive money. Good luck to you
