The Mystery of the Missing Public Key in Your PSBT
As a bitcoin developer or user, you’re likely familiar with the concept of public keys and private keys. In this article, We’ll Delve Into Why Your PSBT (Public Script Broadcast) Might Be Missing a Public Key.
Understanding Psbts and Private Keys
A PSBT is a script that contains information about how to broadcast a bitcoin transaction on the network. It’s essentially an encoded message that describes what action to take when broadcasting a transaction. Each Line of the PSBT Repeats A Specific Operation, Such as “Set Recipient” Or “Create Signed Output.”
Private keys, on the other hand, are used to verify and sign bitcoin transactions. They’re generated using the elliptic curve digital signature algorithm (ecdsa) with a specific public key.
