Welcome back on our blockchain journey! We have covered a lot of ground so far, from the history of money and why blockchain cryptoassets make sense to the foundational technologies of Bitcoin and Ethereum. Now that you have a good understanding of Bitcoin and Ethereum, which pioneered the first and second generation of this technology, we can move on and introduce some other interesting projects related to these technologies.
The following topics will be covered in this chapter:
- The different categories of blockchain
