Wallets for Devs: Transactions, Scripts + SegWit
All about Bitcoin wallet protocols, such as descriptor wallets, PSBTs, HD wallets, mnemonics. (BIPs 32, 39, 174, 370), and Miniscript.
About this course:
Wallets today have high standards for keeping complexity at bay with simple interfaces. Bitcoin has some of the most advanced protocols for keeping secrets safe while also providing portable protocols which allow for users to securely move their funds between platforms. Exercises in this class will be in Python using Jupyter Notebooks. Nix strongly recommended for installing the dependencies.
What to know before class (pre-requisites):
It’s strongly recommended that you have a strong understanding of bitcoin transactions before taking this class, such as the topics taught in flagship our Transactions Deep Dive class.
Topics we'll cover:
xpubs and xprivs aren’t complicated. We’ll build a tool that allows us to derive any path for HD wallets and learn about common wallet paths.
We’ll build a parser that can take seed words and transform them into a seed for BIP32.
This modern protocol is used for communicating information about how to unlock bitcoin. We’ll dive into how they work.
Learn how wallets communicate data with the PSBT protocol.
What’s updated in the newer version of the PSBT spec?
Dive into BIP127 and BIP322 to understand how you can prove what you own.
"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!"
"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!"
"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."
