Study Notes | Hash Functions
① The same input always produces the same hash. Even changing just one character in the input will make the hash completely different.
② Ethereum uses Keccak-256. Its padding rules differ slightly from those of the final standardized SHA3-256, so they produce different results.
③ Don’t confuse a transaction hash with a private key: transaction hashes can be public, but never share your private key or recovery phrase.
