What Is the Significance of the “Version” Field in a Bitcoin Transaction?

The "version" field is a small number in a Bitcoin transaction that indicates which set of protocol rules the transaction adheres to. It allows for the introduction of new features or transaction types (like SegWit) while maintaining backward compatibility with older software.

By changing the version number, the network can signal and enforce new rules for how a transaction is processed without requiring all nodes to upgrade simultaneously.
