Friends, this is something you definitely need to understand: hash functions!
Ethereum uses Keccak-256. Keccak-256 differs from the later finalized SHA3-256 in its padding rules, so they produce different results.
The block header records the hash of the previous block. Changing any historical block changes that block’s hash, so all the subsequent blocks no longer match.
$BTC mining is essentially repeatedly calculating SHA-256 hashes to find a result that meets the difficulty requirement.
Save this for now and take a closer look later 👇
