Everyone, this is a concept you really need to understand: hash functions!
SHA-256 always produces a 256-bit output, which is 64 characters when written in hexadecimal.
Proof of work works because hash results can’t be predicted in advance. Finding a hash that meets the difficulty requirement takes repeated attempts.
$BTC mining is essentially repeatedly calculating SHA-256 hashes to find a result that meets the difficulty requirement.
