# Summary

You have now worked through the move from Web2 to Web3, with a focus on how Chromia handles it.

You started with the history of the web to see why Web3 is the logical next stage. From there, you compared the traditional Web2 development stack with the newer Web3 stack, using practical code examples to show where they differ and where they overlap. You also looked past the code itself to scalability, security, and economy.

With that background, moving to Web3 should feel more approachable. For more practice with Rell and building dapps on Chromia, continue with the [introductory dapp development course](https://chromia.com/learn/book-review/introduction/) and then the [advanced dapp development course](https://chromia.com/learn/my-news-feed/introduction/).

Happy coding!
