A fixed-length output from a cryptographic function applied to arbitrary input data. Hashes are one-way and deterministic — the same input always produces the same hash, but you cannot reverse it.

Understanding this concept is essential for anyone entering the crypto space. It forms the foundation upon which more advanced topics like DeFi, trading, and security are built.
