What exactly is a hash, and why does blockchain depend on hashes? Many people can't explain it clearly!
Ethereum uses Keccak-256. Its padding rules differ slightly from those of the finalized SHA3-256 standard, so the results are not the same.
The block header stores the hash of the previous block. Tampering with any historical block changes its hash, meaning all subsequent blocks would have to be recalculated.
If you see a project promising stable, high returns, be skeptical.
