What exactly is a hash, and why can’t blockchain do without it? Don’t worry—the class rep is here with the answers:
Ethereum uses Keccak-256. Keccak-256 differs from the later standardized SHA3-256 in its padding rules, so they produce different results.
Proof of Work works because hash results can’t be predicted in advance. The only way to find a hash that meets the difficulty requirement is to keep trying.
Useful knowledge won’t make me rich overnight, but it can help me avoid a few pitfalls.
