"As a junior developer it's a daunting task jumping into Bitcoin development for the first time, I've tried on my own and failed multiple times in the past. Base58 gave me a new opportunity to dive in again guided by a real expert in the industry along side a class of likeminded students. This has been invaluable for my understanding of the Bitcoin protocol and has given me examples and actionable next steps for developing my skills and starting to build on Bitcoin for real. Thank you Base58!"

Front End Engineer @ Fold

"Phenomenal course. Came into it with limited technical knowledge of bitcoin. They make it super accessible (no dev experience needed, interactive and fun) and I'm now sooo much more comfortable with the technical side of the bitcoin fundamentals. In fact, some of the things I learnt helped me while interviewing at bitcoin companies! If you're interested in bitcoin and want to learn about how it works - highly recommend taking this course!"

Sr. Software Engineer @ Swan Bitcoin

"I thought I knew how transactions worked in bitcoin up until I took the class. It is a deep, byte by byte dive into the different types of transactions, understandable for non-coding people. Just have an open mindset, let yourself be taught the most basic bitcoin-cli and python commands, and you are good to go. I was afraid it would be too technical, and don't get me wrong, it does get into the roots of how the transaction protocols work, but nifty managed to keep it simple and clear enough for someone with a basic bitcoin knowledge to follow."
