Blockchain seems like a good idea on the surface. However, in practice, I haven’t come across situations where it’s the best solution.

I mean, the whole idea of data immutability and a kind of “democracy” for information sounds cool, but the drawbacks are quite significant for real-world use.

The main selling point, that data can’t be altered, isn’t entirely true. Ethereum, for instance, had a fork because a group in charge decided to change some data. In smaller blockchain networks, a malicious actor could set up enough nodes to control over 50%, giving them the power to manipulate things.

Plus, it’s not very eco-friendly. Adding or modifying data involves a lot of computationally intensive processing, often done redundantly by multiple machines simultaneously. So, it ends up consuming a ton of energy just to add a single entry to a database.
