This first chapter is designed to acquaint you with the key concepts behind blockchain, which you'll need to build blockchain projects.
We have seen how to interact with bitcoin's blockchain both manually and programmatically (using JavaScript). Now you can start building innovative solutions harnessing blockchain as a safe and trustworthy vault to help with checking the authenticity of documents, proving the provenance of products, asset digitization, and more.
A deep understanding of bitcoin is key to deciphering blockchain. In the next chapter, we will continue learning about bitcoin, and build an advanced payment application.
