qLabs launched Quantum-Sig, its own wallet promoted as a defense against quantum attacks. It also announced a limited presale of its token, qONE, with an estimated launch date of February 5th.
qLabs announced the launch of its Quantum-Sig wallet, which is specifically designed to prevent quantum theft and is aligned with NIST, using zero-knowledge proofs and a dual-signature model.
One of the unique features of the launch is that each transaction requires both a standard blockchain signature and a second signature that resists quantum computing. This measure would render data collected today unusable for future quantum machines.
Part of the project is the launch of a qONE token with a limited presale ending February 5th, positioning the offering as a direct shield for the user rather than a protocol-level migration.
qLabs: a race driven to improve user security
Meanwhile, Coinbase took a different approach by creating an Independent Advisory Board on Quantum Computing and Blockchain. The company includes experts in the field, and its main objective is to publish research, assess risks, and advise on potential strategies.
In public presentations and reports related to the measure, Coinbase has warned that between 20% and 50% of the Bitcoin supply could be vulnerable to future quantum attacks, framing the work as a multi-year migration rather than an immediate product launch.
qLabs offers immediate wallet-level mitigation that users can adopt without waiting for protocol changes; however, it addresses the problem at the edge rather than changing the core primitives of the chain. While Coinbase’s plan aims for resilience at the protocol and ecosystem level, it requires long timelines, coordination, and likely complex migrations.
For market participants and custodians, the practical options are clear: adopt the available wallet-level protections now to reduce short-term harvest risks, while monitoring and participating in the longer, standards-guided migrations that custodian platforms and protocol communities are planning.
