What does the blockchain represent? Is it the current balance of each account or is it the complete ledger?

  • Hello Yash, Welcome to Bitcoin.SE. Those are some interesting questions, but posts with multiple topics don't work well on our site. Please only ask about one topic per post. You can read a discussion about this here: Should we split up posts that ask many questions at once? I'll edit your post down to one question, please post the others as separate posts. Thank you.
