StarkWare's contest cuts quantum-safe bitcoin cost estimate to $66

by@laurashin

Summary

In an effort to enhance bitcoin transaction security against quantum threats, an open coding contest hosted by StarkWare has significantly reduced the estimated cost of executing a quantum-safe bitcoin transaction from approximately $320 to about $66 within one week. This contest, which commenced on September 16 and features $20,000 in prizes, focuses on optimizing GPU code for Quantum-Safe Bitcoin (QSB) transactions, a method introduced by StarkWare that adds hash-based protection without altering bitcoin's underlying rules. Notably, the competition incorporates AI tools to improve performance, reflecting a broader trend in the industry towards collaborative, community-driven challenges to advance cryptographic techniques. However, StarkWare emphasizes that the $66 figure is merely an estimate tied to specific hardware assumptions and does not guarantee full quantum safety for bitcoin since it only protects unexposed public keys.

Analysis

StarkWare: StarkWare develops scaling and cryptographic tools for blockchain networks. It organized the Quantum-Safe Bitcoin Optimization Challenge in partnership with others to refine an off-chain process for protected Bitcoin spends. The company positions the resulting estimates as a practical way to maintain an emergency option without altering Bitcoin's core rules. Avihu Levy: Avihu Levy is a researcher at StarkWare who originated the Quantum-Safe Bitcoin approach. His April publication established the hash-based protection method that underpins the current optimization effort. Eigen Labs: Eigen Labs engages in research on cryptographic methods and decentralized protocols. It joined StarkWare and Yukon Research to run the open coding contest aimed at optimizing Quantum-Safe Bitcoin implementations. Yukon Research: Yukon Research participates in cryptographic and blockchain research initiatives. It co-launched the Quantum-Safe Bitcoin Optimization Challenge alongside StarkWare and Eigen Labs and helped establish the associated prize pool. Quantum-Safe Bitcoin: Quantum-Safe Bitcoin, also called QSB, is a technique that layers hash-based signatures onto Bitcoin transactions while preserving existing network consensus. First introduced in April, it enables spends that avoid exposing public keys to quantum risks. The ongoing contest focuses on lowering the GPU-intensive search step required to create these transactions. Security: Protecting only unexposed public keys remains a core constraint when deploying emergency quantum-resistant Bitcoin options. Methodology: Community-driven coding contests paired with AI tools have become a recognized approach for refining computationally intensive cryptographic workloads. Collaboration: Industry groups frequently combine efforts across research organizations to accelerate progress on post-quantum cryptographic techniques for blockchain.
