How to use blockchain technology to upgrade traditional businesses?

First of all, you need to know what a blockchain is. Literally, blockchain is a distributed, independent and unified account book. Generally speaking, the users of this system keep accounts together, and adopt a unique proof mechanism (bitcoin is a proof of workload) to ensure the consistency of everyone's accounting, that is, everyone copies one account book. Of course, this account book can be proved correct by mathematics. When you say to upgrade the traditional business, you must go to the blockchain to have a combination point, so that you can develop. Obviously, banking is the most suitable industry. Remember that his characteristics are that he can't be forged, can't be changed, and has no privacy (privacy can be protected by some technologies), so he is safe. According to its characteristics, you can find the production point by combining with other traditional industries.
