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.
You are right about blockchain technology but you didnt mentioned about the currency created by this,the Bitcoin .and this is the future currency thats why there is no doubt about how will blockchain may save the world
But what we need here is a total adaptation of cryptocurrency,because this will help the universe in transacting,and services to make everything faster and accessible
