Understanding the Basics of SigHash

What is SigHash and its Role in Bitcoin Transactions?

At its core, SigHash is a cryptographic function that serves as the basis for transaction verification in the Bitcoin network. It ensures that transactions are both valid and secure by verifying the transaction inputs and outputs. SigHash, short for “Signature Hash,” is an integral part of Bitcoin’s security model.

How SigHash Ensures Transaction Security

SigHash achieves transaction security by creating a unique digital signature for each transaction. This signature is generated by combining various elements of the transaction data, making it impossible for malicious actors to alter the transaction details without invalidating the signature. This ensures the integrity of Bitcoin transactions.

Brief History of SigHash Development

SigHash has evolved over the years to meet the changing needs of the Bitcoin network. Its development has been closely linked to the advancement of Bitcoin itself. We’ll explore the key milestones in the development of SigHash and how it has adapted to the evolving Bitcoin ecosystem.

The Evolution of SigHash Variants

Original SigHash (SigHashAll) Explained

The original SigHash variant, known as SigHashAll, operates by signing all transaction inputs and outputs, ensuring that any changes to the transaction details invalidate the signature. We will dissect the mechanics of SigHashAll and its role in Bitcoin’s security.

Introduction to SigHash Single, AnyoneCanPay, and NoInput
