I did a presentation for my office and during the presentation I was asked a question that I was not prepared for. It's a more technical question from my perspective, but someone here might already know the answer.
We know that every 10 min a block is created. And a new block has information of the previous block along with its findings and submitted to the net to be verified.
My question is when a pool or an individual miner is doing the verification, do they verify all the transactions starting from Genesis block till the most recent one?
And this goes on after each block is verified. Meaning every new block that needs verification needs to be verified along with all the previous transactions starting from the Genesis block?
