verb | hash
Hashing is like putting your data through a high-tech meat grinder - it takes an input of any size and spits out a fixed-size output that looks nothing like the original. It's the secret sauce that makes blockchain possible, because it allows us to create unique "fingerprints" for each block and transaction.
Example
"I hashed my password with SHA-256 and now it looks like a string of random gibberish. Good luck guessing that, hackers!"
"Yo, I heard you can smoke hash. Maybe that's what all these miners are really doing with their rigs - getting high on their own supply!"
