What Is ‘Immutability’ in the Context of Smart Contracts?

Immutability means that once a smart contract is deployed to the blockchain, its code cannot be altered, deleted, or changed. This feature ensures that the terms of the agreement remain constant and tamper-proof.

While beneficial for trust, it means bugs or vulnerabilities in the original code cannot be easily fixed.
