We’ve just wrapped up week 3 of the Bitcoin CLI live cohort.

Over the past week, participants explored chapters 6 and 7, diving deeper into how Bitcoin transactions can be expanded beyond the basics through multisignatures and Partially Signed Bitcoin Transactions (PSBTs).

The focus was on understanding how multiple parties can collaboratively create and authorize transactions. Participants learned how to create and manage multisig wallets, spend from them, and think through real-world use cases where shared control of funds is essential.

They also worked through the PSBT workflow, gaining hands-on experience with constructing, funding, and signing transactions across different stages.

Throughout the week, participants applied these concepts through practical exercises and met with their study partners to discuss key ideas, compare approaches, and deepen their understanding.

We then came together for the live session, where participants shared their insights, walked through their solutions, and led discussions on the challenges and possibilities unlocked by multisigs and PSBTs.
