MD5/SHA Hash: Understand Blockchain Transaction Hashes by Computing One

Around blockchain and cryptocurrency, you always see 'transaction hash' and 'block hash.' How they arise and why they uniquely identify a transaction is fuzzy from concepts alone.

The hash tool lets you compute SHA-256 for any string, showing intuitively: change the input slightly and the output changes entirely; the same input always yields the same output — the basis for identifying transactions.

It suits learning blockchain principles, cryptography intros, and verifying hash results in development.

The best way to grasp a concept is to compute it once. Bookmark the hash tool and make 'hashing' in blockchain no longer abstract.
