A well written publication my friend you have presented here. You have written well on the importance of blockchain technology and few parts that caught my attention were the parts of immutability, security and trust. These are essential components associated with every blockchain technology.

Though, despite all these features, the technology still has a few draw back even as you have listed a few of them such as complexity, storage limitation, energy consumption etc. This are problems associated with the technology and it has given the tech a serious draw back. I wish you success in this contest my friend.
