Benefits and Disadvantages of Blockchain?

There are both good and dangerous issues with blockchain know-how. Among the advantages embodied are higher safety, a long-term file, and transparency. Nevertheless, among the drawbacks are scalability points and the danger of a 51-percent assault. There are additionally some fears that blockchain technology is probably not as secure as people say it is.
