Computing on Bitcoin #105
September 04, 2026 - Week 36
Welcome to a new edition of Computing on Bitcoin News, our newsletter where we share a curated selection of this week's most relevant developments on the Bitcoin ecosystem.
Let's dive into this week's highlights.
A new blog post by StarkWare details Avihu Levy's Quantum-Safe Bitcoin (QSB) method, which was executed as the first quantum-safe transaction mined on Bitcoin mainnet, moving coins into quantum-resistant storage without any soft fork or change to consensus rules.

The first quantum-safe Bitcoin transaction has been mined
A quantum-safe transaction was mined on the Bitcoin mainnet today that holds up against an adversary running a working quantum computer.
QSB closes the window for this type of attack by adding a second quantum-resistant lock alongside the existing one, built on hash functions instead of elliptic curves.
GOAT introduces GOAT Flow, enabling merchants to accept card and crypto payments from AI agents across multiple networks, with transactions secured by Bitcoin through its BitVM3 bridge and Ziren zkVM.

5 Most Promising BitVM2 Implementations Bringing Smart Contracts to Native Bitcoin
BitVM2 offers a diverse approach. It takes most computation off-chain and uses Bitcoin to verify disputed results. This can infuse more programmability without changing Bitcoin's consensus rules.
A new article explains BitVM and its history.

What Is BitVM and How It Puts Smart Contracts on Bitcoin
BitVM is a computing design that lets arbitrary programs be verified on Bitcoin without changing Bitcoin's consensus rules. The computation runs off-chain between two parties, and Bitcoin only sees a short challenge-response game if one side lies.
That wraps up this week's edition of Computing on Bitcoin News.
We hope you found it useful and look forward to bringing you more developments next week.
