noun | fahy·na·luh·tee
Finality is like when you send a risky text to your ex and then see the "read" receipt - it's the point at which a blockchain transaction is considered irreversible and permanently recorded on the ledger. It's like a digital tattoo that you can't laser off, no matter how much you regret it later.
Example
"I sent 10 ETH to the wrong address and thought I could just call up Vitalik and ask for a refund. Turns out, finality is a bitch and now I'm eating ramen for the rest of the month. Should've double-checked that address like my mom always told me."
"Finality is what separates the blockchain from your bank account - with a bank, you can always dispute a charge and get your money back if you make a mistake. With the blockchain, once you hit send, that shit is gone forever. It's like playing Russian roulette with your life savings, but instead of a gun, it's a computer program created by some anonymous nerd."
