Blockchain is a chain of transactions in the Bitcoin system, which accelerates transactions and protects them from external interference. In addition, developers have realized that it can help transfer not only money, but also any data. It makes it easy to obtain certificates from state agencies and makes the taxation system transparent: every taxpayer knows where his/her money goes.
