I didn’t understand this when I first got into crypto either.
Ethereum uses Keccak-256. Keccak-256 and the finalized SHA3-256 differ in their padding rules, so they produce different results.
Each block header stores the hash of the previous block. Changing any historical block changes that block’s hash, so all subsequent blocks would have to be recalculated.
$BTC mining is essentially just repeatedly calculating SHA-256 hashes to find a result that meets the difficulty requirement. Currently, 77628.01.
When did everyone first figure this out?
