Think of it as "safety in math" since finding golden nonces requires an enormous amount of time and computing power. Unlike traditional currencies, no government, central bank, or physical asset backs cryptocurrencies. “Blockchain technology” is acceptable to refer to the computer code that records cryptocurrency transactions (and can be used for other things; stay with us). Standing alone, just call it the blockchain – even though there are actually multiple (don’t worry, we’ll explain below).
