New wallet offers way to tackle Bitcoin’s quantum risk without a fork
Postquant Labs introduces a new wallet using Arch Network to provide post-quantum security for Bitcoin without requiring network changes.Summary
Postquant Labs has unveiled Quip Network, a new Bitcoin wallet designed to mitigate quantum computing risks using the Arch Network. Unlike previous proposals from developers like Jameson Lopp or Paul Sztorc, which suggest soft or hard forks, Quip utilizes a Layer 2 approach to implement the WOTS+ (Winternitz One-Time Signature) post-quantum signature scheme. This method allows for quantum-resistant security without requiring any changes to Bitcoin's base layer or consensus rules.
The project aims to provide immediate protection, bypassing the potential 5 to 10-year delay associated with protocol upgrades. While critics argue that Layer 2 solutions might still leak public keys during transaction broadcasting, Postquant Labs claims their approach narrows the window for a quantum attack to approximately 20 minutes. The wallet is scheduled to launch next week, with third-party audits currently underway.
