Blockchain is called a technology that will change us just as the Internet has changed it. blockchain ideologists claim that it is about to lead humanity to a ultra-modern world where there is no theft and deception. how will this happen? Will the blockchain become the Savior of our world economy or its killer? If the blockchain is tightly integrated into our lives, the unemployment rate will increase, and on a huge scale. And this can lead to a large percentage of poverty among the population. Will the world economy sustain such a large number of unemployed, or will society be further divided into social classes.
