noun | hash fuhngk·shuhn
A hash function is like a digital fingerprint kit - it takes an input (like a block or transaction data) and creates a unique output (the hash) that can be used to verify the integrity of the data. It's a one-way street, meaning you can't reverse-engineer the input from the output - kinda like how you can't un-eat a burrito.
Example
"The SHA-256 hash function is the backbone of the Bitcoinblockchain - it's what keeps everything secure and tamper-proof. Without it, we'd just be trading Chuck E. Cheese tokens on an Excel spreadsheet."
"I'm thinking about creating my own hash function that outputs dank memes instead of boring hexadecimal strings. That's the future of crypto, mark my words!"
