Abstract: We can learn a lot of things from blockchain technology. Then, let’s consider the different areas where this technology may prove useful in the future. The first use of blockchain technology for implementation is electronic funds transfer with bitcoin in 2008. Actually, there are many things that blockchain technology can be applied to. It also poses some real problems to existing financial systems. Firstly, some of the predictions about blockchain are that it will radically disrupt the banking world; the opinion of every possible observer is that the challenge is still endless. Additionally, the most important difficulty will have a direct relationship with the components of blockchain—trust and incentives. So by the medium of the blockchain which is least controlled by technical scientists, people can basically negotiate or choose a “good” solution to the issue without the technical effects of their choice being visible.
