Insider Brief
- QANplatform’s quantum-safe cross-signer protocol, QAN XLINK, has passed a full cybersecurity audit by Hacken, validating its defenses against future quantum-based attacks.
- QAN XLINK enables Ethereum-compatible wallets to use post-quantum signatures, addressing the vulnerability of exposed public keys across major blockchains.
- The audit aligns with rising concern from organizations such as NIST and BlackRock about the growing quantum threat to blockchain security.
PRESS RELEASE — QANplatform, the blockchain platform delivering quantum-resistant security for Web3 development, today announced that its QAN XLINK, a cross-signer protocol that enables integration of Ethereum-compatible wallets with quantum-safe signature-capable keypairs, has successfully completed a comprehensive cybersecurity audit by blockchain security firm, Hacken. This confirms the protocol’s ability to protect against the looming threat of quantum computing attacks on blockchain networks.
The growing quantum threat poses a significant risk to existing blockchains. Even a single transaction from a wallet exposes its public key, leaving the cryptocurrency potentially vulnerable to theft by future quantum computers. In fact, all Bitcoin, Ethereum, Solana, Cardano, and other blockchain addresses are susceptible to quantum attacks once their public keys are exposed, with around 6.65 million Bitcoin addresses (approx. 25% of total Bitcoin supply) and over 65% of all Ether having exposed public keys, according to recent estimates.
QANplatform addresses this with QAN XLINK, a protocol that seamlessly integrates with existing Ethereum-compatible wallets like MetaMask and Trust Wallet, enabling quantum-safe signatures. Utilizing NIST’s primary-recommended lattice-based Post-Quantum Cryptography (PQC) algorithm (ML-DSA, FIPS 204), QAN XLINK provides a 100%-guaranteed safe migration path for the post-quantum era ensuring security even after “Q-Day.” QANplatform is the only blockchain that delivers both Ethereum compatibility and a guaranteed quantum-safe migration.
The threat of quantum computers is imminent, as leading organizations including the National Institute of Standards and Technology (NIST), the Federal Reserve, and BlackRock are all warning of the impending vulnerability. QAN XLINK and Hacken’s audit come at an opportune time, as the NIST issued its post-quantum cryptography standard and BlackRock updated its Bitcoin ETF prospectus to highlight the growing quantum risk.
“Following the success of our QVM, we’re forging the path to bring post-quantum security to the broader Web3 ecosystem,” said Johann Polecsak, Co-Founder and CTO of QANplatform. “Hacken’s thorough audit of QAN XLINK bolsters confidence in our ability to deliver forward-looking security, while also building the world’s first Ethereum-compatible, quantum-safe hybrid blockchain.”
“The quantum threat is no longer a distant concern, it demands proactive preparation for the whole web3 ecosystem. Developing a quantum-safe protocol and performing rigorous audits of the code behind the protocol, QANplatform’s and Hacken are both pioneers and advocates for a quantum-safe Web3 ecosystem.”
— said Yevheniia Broshevan, Co-founder & CEO of Hacken.
