The image you shared is a simple diagram of the Proof-of-Work process in a blockchain. It shows how miners compete to find a nonce that results in the required hash with leading zeros. Plain language breakdown: It's like playing "hot or cold" but for computers. The "nonce" is just a magic number they're guessing. The computer keeps changing this nonce until it gets the hash (a scrambled string of numbers and letters) just right, starting with those specific zeros we want. This game proves they've done some digital digging (work). Once this puzzle is solved, and the block is added to the chain, changing anything would mean redoing all that hard work—not just for one block but for every single one after it too. In short, it's like saying: "Look at how much effort I put into locking this up tight! Good luck trying to pick this lock without doing all that work again." #Bitcoin #Blockchain #ProofOfWork #Mining #Security
