"content": "We just wrapped up week 4 of the live cohort of the Bitcoin CLI pathway. 🚀\n\nDuring the week the cohort explored how Bitcoin transactions can go beyond simple payments.\n\nIn chapter 8, we learned how transactions can include additional conditions. Participants explored locktime, which allows a transaction to be valid only at a certain time or block height, and OP_RETURN, which makes it possible to attach small pieces of data to the blockchain. These features show how bitcoin transactions can be more flexible than just sending funds.\n\nIn chapter 9, the focus shifted to Bitcoin Script, the programming language that defines how bitcoin can be spent. The cohort explored how scripts set the rules for transactions, and why testing scripts is important when designing spending conditions.\n\nThroughout the week, participants reviewed the study materials, completed the technical exercises, and met with their assigned partners to discuss key questions.\n\nDuring the live study session, participants shared their insights and faculty members led short discussions with the group.\n\nWeek 4 helped the cohort move from basic transactions to understanding the scripting logic that powers Bitcoin.\n\nhttps://npub1353snusdats4lpgwel4frhlmm05w6md2u89gss0dcdzamlhm2yas25gajp.blossom.band/7609a7ac43c8fe8adcd9a77669cd65d34cf02d869c27479d33bb8b335fd02f2f.jpg\n https://npub1353snusdats4lpgwel4frhlmm05w6md2u89gss0dcdzamlhm2yas25gajp.blossom.band/c9a71567358427717de058873b984f5d0e9780e48a069ea836666b761574ab8c.jpg\n https://npub1353snusdats4lpgwel4frhlmm05w6md2u89gss0dcdzamlhm2yas25gajp.blossom.band/52356b76e7392e860fb7b4b3d964bce3dd60d3e69cd2e9efde59715574c06868.jpg",
