What exactly is blockchain? Don’t panic—the class rep is here with the answer:
Bitcoin produces a block on average every 10 minutes. After Ethereum switched to proof of stake, it produces a block every 12 seconds, one per slot.
On a proof-of-work chain, rewriting an old block means recalculating all the blocks after it and catching up with the ever-growing main chain across the network—a very costly undertaking.
There’s no homework for this lesson, but the market may give you a pop quiz.
