Having said so much, I wanted to remind everyone to think about it. The bottom of the blockchain is still a “decentralized” system. Through more understanding of decentralized systems, we can give us the value that the blockchain provides. More understanding. I have only recently started to study decentralized systems. I gradually understand what problems are the problems of “decentralized systems” and what problems are “plus decentralization”. This process of learning is a process of learning. It also made me even more admired that "blockchain is a god's invention!" In short, this is a bit of caution for me to learn to look back at the blockchain in the decentralized system. There are not many, and I hope we can learn more in the future. Share it with everyone. Then, everyone will look forward to the next discussion on "decentralization"!
