# BitVM 8 bit CPU: Write Bitcoin programs in Assembly

{% embed url="<https://www.youtube.com/watch?v=lQ9agL725G0>" %}

Super Testnet has built an 8 bit CPU for BitVM, so programs are easier to create. I walkthrough how it works and a tool to help you write these programs. Let me know in the comments if you write any interesting programs, or share them in the BitVM Builders Telegram group!
