【Quick explainer】What exactly is a hash, and why can’t blockchain do without it?
Ethereum uses Keccak-256. Its padding rules differ slightly from those of the finalized SHA3-256, so they produce different results.
Mining $BTC actually means continuously calculating SHA-256 hashes to find a result that meets the difficulty requirements.
Every potential return comes with corresponding risks, so first make sure you understand how much you could lose in the worst case.
