Blockchains depend on cryptographic systems that safeguard private keys, allowing users to approve transactions and prove control of their assets. These systems rely on one-way mathematical functions and vast key spaces that are practically impossible to break using today’s classical computers. This structure has enabled cryptocurrencies to operate securely for more than a decade.
The industry now faces an emerging risk. Experts expect quantum computers powerful enough to crack widely used cryptographic algorithms to appear in the 2030s. Such machines could potentially derive private keys from public keys, exposing users’ wallets and destabilising existing blockchain networks. Although the threat is not immediate, the sector recognises the need for proactive upgrades.
QANplatform Builds for a Post-Quantum Blockchain Era
QANplatform has developed a blockchain designed for future quantum conditions. Its cross-signer protocol, QAN XLINK, acts as a bridge into the post-quantum era. The protocol issues dual signatures using classical cryptography along with a Post-Quantum Cryptography (PQC) algorithm. It is compatible with the Ethereum Virtual Machine and integrates seamlessly with wallets such as MetaMask and Trust Wallet. This dual system enables a smooth transition from current algorithms to quantum-resistant ones without disrupting existing user workflows.

Hacken’s audit found that QAN XLINK offers effective protection against the anticipated quantum threat. The confirmation strengthens confidence in QANplatform’s architecture and its roadmap for quantum-safe blockchain technology.
Security Checks Ahead of Mainnet Launch
Hacken had previously audited the QAN Virtual Machine, which supports smart contracts and decentralised applications on QANplatform. The firm applied an AI assisted methodology to examine the virtual machine and approved it for deployment.
Following the latest audit, QAN XLINK has now completed its second major security review before the platform’s mainnet release. QANplatform will conduct another integration audit in the coming months to ensure smooth interaction between all blockchain components.
Johann Polecsak, co-founder and chief technology officer of QANplatform, said the audit strengthens their commitment to building a forward-looking network designed to withstand the impact of quantum computing.
Preparing for a Cryptographic Shift
Quantum computing will eventually require blockchains to function under new security rules. QANplatform intends to adapt early rather than treat the challenge as a distant concern. Its work on post-quantum signatures, interoperability and compatibility reflects a strategy focused on long-term continuity. The aim is to upgrade cryptography without forcing developers or users to overhaul their existing practices.
Industry leaders such as Ethereum co-founder Vitalik Buterin have warned that elliptic curve cryptography will become ineffective once quantum systems mature. QANplatform aligns its development with this view, positioning itself to remain functional in a landscape where post-quantum algorithms define digital security standards.
Polecsak has also noted that many blockchains may struggle with this transition. Networks that adapt early will shape how digital assets are protected in the decades ahead.
A Network Built for Everyday Quantum Safety
QANplatform’s approach places post-quantum protection at the core of everyday blockchain use, not as an extra layer added under pressure. With the successful audit of QAN XLINK, the project takes another step toward delivering a resilient, quantum-safe environment for developers, businesses and users preparing for the next era of secure computation.
