Quantus has launched a proof-of-work blockchain with post-quantum cryptography integrated into its mainnet, positioning the network as a response to potential security risks posed by advances in quantum computing.
Quantus launches quantum-resistant mainnet
The project said its mainnet was designed with quantum resistance from the outset rather than relying on a later security upgrade. Quantus is betting that protection against quantum-enabled attacks will become an increasingly important requirement for cryptocurrency networks.
Quantum computers remain under development, but researchers have warned that sufficiently powerful systems could eventually threaten some of the cryptographic methods used to secure digital assets. These risks could include attacks on public-key cryptography, which helps authenticate transactions and control blockchain-based funds.
Post-quantum cryptography as a security measure
Post-quantum cryptography refers to cryptographic algorithms designed to resist attacks from both conventional and quantum computers. By incorporating such technology at the protocol level, Quantus aims to reduce the need for disruptive changes if quantum computing capabilities advance.
The project has framed the issue as a potential threat to a large portion of the cryptocurrency market, citing an estimated $2.7 trillion in digital-asset value that could ultimately require protection from quantum-related risks. The figure represents the scale of the broader security concern rather than a reported loss or confirmed attack.
Proof-of-work network
Quantus uses a proof-of-work consensus model, in which network participants use computational resources to validate transactions and help secure the blockchain. The mainnet launch marks the transition from development to a live network, although adoption, usage and long-term security will depend on participation from developers, miners and users.
Quantum-resistant standards are still evolving across the technology industry. As a result, the effectiveness of any blockchain’s approach will depend on the cryptographic algorithms it uses, how they are implemented and whether they can be updated as security research progresses.
