The picture you've linked is a graphical representation of "verification," with someone touching a virtual interface that says "VERIFICATION." It's symbolic of how digital systems confirm the validity of data, which ties in nicely with the concept of Simplified Payment Verification (SPV) in Bitcoin.
For Simplified Payment Verification Paragraph 1:
Let's break it down real simple. You don't need to download the whole Bitcoin history to check if a payment went through. Just like you don't need every text message ever sent to find one from your buddy saying he paid you back for pizza last night.
With SPV, instead of having all transactions, you just keep track of block headers – they're like summaries or contents pages for blocks. By getting these from nodes (the referees in our global digital game), anyone can verify their own transactions by seeing that it's included in one and then locked in by the ones after it.
It’s like checking receipts without having to go through every purchase ever made at the store – quick and easy proof!
