Catenaa, Saturday, February 07, 2026- Nervos CKB has deployed SPHINCS+ cryptography and launched the Quantum Purse wallet, giving users the ability to protect assets against future quantum computing threats, the foundation said Monday.
CKB, a RISC-V-based Layer-1 blockchain, enables users to opt into post-quantum security without requiring consensus-level changes. The implementation targets vulnerabilities in ECDSA, the digital signature algorithm used for transaction authorization, which is considered at risk once sufficiently powerful quantum computers—sometimes projected as early as 2030—become operational.
The Quantum Purse is a self-custodial wallet available for Linux, Mac, and Windows, supporting NIST-standardized, hash-based, quantum-resistant cryptography.
Nervos said the wallet is designed to provide security for decades while maintaining compatibility with existing blockchain operations.
Unlike many networks, CKB allows developers to select cryptography and programming languages at the smart contract layer, providing flexibility to implement quantum resistance without hard or soft forks. The foundation said this approach lets users and developers adopt advanced security measures quietly, using open-source, vetted tools.
Nervos CKB uses a flexible UTXO-based model and Proof-of-Work consensus, forming the base of the Nervos Network, which focuses on long-term security, decentralization, and permissionless innovation.
The foundation noted the deployment marks a major step in preparing the network for future cryptographic risks while maintaining operational stability.
Additional information and downloads for Quantum Purse are available on the Nervos GitHub and technical documentation portals.
