What is blockchain in simple words?
Could you please explain blockchain in simple terms? I've heard a lot about it, but I'm still not entirely sure what it means. Is it just a fancy word for a database or is there more to it? How does it work, and why is it so important in the world of cryptocurrency and finance? I'm trying to understand the basics so I can better grasp the larger concepts in this field. Can you break it down for me?
