The regulations and cost of transactions has yet to evolve considerably.

This makes possible the creation of a universal virtual machine like Ethereum. [Cat McGee](https://hashnode.com/@catmcgee) [Oct 6, 2021](https://hashnode.com/posts/why-web3-matters/61537495414f78089df3b6ef/comment/615d1095cb42f364a52f764a#reply-615d5d66cb42f364a52f7d57) This is true! However in my opinion the normal use case of blockchain should be finance - it is incredibly expensive and just unfeasible for most other projects. There are some other purposes, things that have to be highly secure like identification, and I'll probably write a separate article about those soon [Marko Denic](https://hashnode.com/@denic) [Oct 2, 2021](https://hashnode.com/posts/why-web3-matters/61537495414f78089df3b6ef/comment/61584b9b70a8165c11f63a15) Great article!
