About

21 Lectures' mission is to bring more developers to the Bitcoin ecosystem. Lectured by the world's best Bitcoin developers, our courses teach participants the fundamentals to work with Bitcoin & related technologies. We are fulfilling the market's demand for experts and are strongly rooted in the tech-community.

 

Information wants to be free

 
 
A piece of knowledge, unlike a piece of physical property, can be shared by large groups of people without making anybody poorer.
— Aaron Swartz
 
 

We believe in the power of open source software, creative commons and that all people should be able to access information freely. This is why we publish all our teaching materials freely available to use, share, copy, distribute and modify. You can find our course material on GitHub. If you want to provide the same courses in your country: Go for it! We would love to hear your feedback and welcome any contributions to our material.
