Ethereum or Base Tx hash use Keccak-256 algorithm.
That's, one-way function:
you can input data → and get a hash
but the hash → cannot be reversed back to the original data
retrieving the original data from only the hash → impossible
The probability of finding an input that matches a specific hash is 2²⁵⁶ possibilities. That’s equivalent to trying every atom in the universe multiple times.
A tx hash is one-way, but the transaction data itself is not secret.
