Hash: meaning in crash games
The output of a one-way function such as SHA-256. Any change to the input changes the hash completely, and the input can't be worked out from the hash, which is what makes seed commitments trustworthy.

Why it matters
Hashes let a game commit to a result without revealing it.
In practice
SHA-256 and SHA-512 are the most common hash functions in provably fair games. Both are one-way: you can check a seed against its hash in microseconds, but finding a seed for a given hash is computationally out of reach.
Example
SHA-256(“abc”) always gives the same 64-character result.
