What are some real-world examples of immutable data?

Immutable data refers to data that cannot be changed once created. Some real-world examples include blockchain, where transaction records are permanent, and version control systems like Git, which track changes without altering previous versions.

Can you explain how blockchain uses immutable data?

Sure! In blockchain, each block contains a list of transactions and a cryptographic hash of the previous block. This structure ensures that once a block is added, it cannot be altered without changing all subsequent blocks, making the data immutable.

What are the benefits of using immutable data?

The benefits include enhanced data integrity, easier debugging, and improved security, as it prevents unauthorized changes and ensures a reliable history of data.

Are there any downsides to using immutable data?

Yes, some downsides include increased storage requirements since all versions of data are kept, and potential performance issues when dealing with large datasets that require frequent updates.
