New Wallet Offers Solution to Bitcoin's Quantum Risk Without Requiring a Fork

The developers of a new wallet claim to have found a method to mitigate the risks associated with quantum computing using a smart contract layer that operates in conjunction with Bitcoin, eliminating the need for any changes to the network itself. Postquant Labs introduced the Quip Network's post-quantum bitcoin wallet on Tuesday, which runs on Arch Network, a system enabling developers to build smart contracts directly anchored to Bitcoin. The wallet utilizes a post-quantum signature scheme called WOTS+, which is a tested cryptographic technique that does not rely on elliptic curve math vulnerable to quantum computers. By utilizing a 'Layer 2' network, developers can add features without altering Bitcoin's base layer. The launch comes amidst an ongoing debate over how Bitcoin should address quantum risk, with some proposals including a soft fork or a hard fork. The Quip approach requires no soft fork, consensus change, or community vote, offering an alternative solution to the existing proposals.
