Blockchain is like a digital ledger for our world. It keeps records safe and honest. Imagine it as a big, secure diary that lots of people can see but can't change. Now, how does it help society? Well, it makes online transactions safer. When you buy things or send money, blockchain checks everything, so no one can cheat you. Also, it's useful for voting. People can vote online, and nobody can fake the results. So, in simple words, blockchain and society are good friends. They protect your money and make sure your voice counts when you vote.
