We’ve reached the final week of the Bitcoin CLI live cohort, and today marked our last live session together. 🧡

Over the past 6 weeks, participants have been working directly with the Bitcoin command line interface to better understand how Bitcoin works at a deeper technical level.

This final week focused on expanding Bitcoin scripts and designing Bitcoin scripts.

In chapter 12, participants explored how Bitcoin scripts can include conditions that change how funds can be spent. Instead of having only one way to unlock a transaction, scripts can be written so that different rules apply depending on certain conditions. For example, one spending path might require a signature, while another path could activate after a certain condition is met.

In chapter 13, the focus shifted to examples of Bitcoin scripts and how developers actually design them. Participants looked at scripts that act like puzzles, where funds can only be spent if the correct answer or condition is provided, and more complex multisignature scripts that require approval from multiple keys. These examples helped demonstrate how the different pieces of Bitcoin Script come together to control how funds move on the network.

Throughout the week, participants reviewed the study materials, met with their partners to discuss the questions, and began working on the technical capstone project, which brings together many of the concepts explored throughout the cohort. 🚀
