Finality
The point when a transaction or block is considered permanently locked in and can never be reversed.
Different chains have different finality times. Bitcoin uses probabilistic finality (more confirmations = safer) while many new chains give instant or fast finality.It's like the moment the judge hits the gavel and says the verdict is final — no more appeals.
Real world: Proof of Stake chains like Ethereum reach finality after about 15 minutes, meaning your transaction is 100% safe and can't be reorged.
💡 Understanding finality helps you know when you can truly relax after sending crypto — always wait for it on big transfers.
