What are the main problems in the development of blockchain technology at present?

At present, blockchain technology is still in a very early stage. Not only has a unified technical standard not yet been formed, but various technical solutions are still developing rapidly. However, in the past, it was thought that the system based on blockchain technology would consume a lot of resources (similar to bitcoin), or the system based on blockchain technology made a technical breakthrough in the problem of limited data processing capacity. However, the scalability of blockchain technology has not been tested by large-scale practice, and now it is mainly in the prototype design stage. In addition, the blockchain industry is very short of talents. If you want to know about blockchain, you can go to chain broadcasting, where there are many blockchain information updates every day, as well as blockchain technical training and blockchain related activities. Those who are interested can go and have a look.
