Technical principle | How does the blockchain confirm that a transaction was really sent by you?
Digital signatures use a pair of keys: the private key generates the signature, and the public key verifies it. You cannot derive the private key from the public key.
A signature prompt in your wallet isn't necessarily for a transfer; it could also be for token approval or an off-chain signature. The effects of signing it may be similar to those of a transfer.
When sending out $BTC , your wallet signs the transaction with your private key, and nodes across the network verify the signature using the public key. Currently: 83632.01.
The market is always full of surprises, so think in advance about what to do if your judgment is wrong.
