The First Post-Quantum Digital Signature Add-On for Future-Proof International Documents Is Released by SignQuantum
A revolutionary software add-on created to protect digitally signed documents from the quickly developing threat of quantum computing has been formally introduced by SignQuantum, a post-quantum security provider and a product of Qatar-based Quantum Software Solutions. Organizations can move to post-quantum security without having to completely revamp their current workflows to this creative solution’s seamless integration with existing e-signature platforms. Important attendees at the Doha launch event were H.E. Sheikh Mansoor Bin Khalifa Al-Thani, the founder and chairman of MBK Holding; Nazmath Nazeer, the CEO of SignQuantum; and Johann Polecsak, co-founder and CTO of QANplatform.

The Impending Quantum Threat to Digital Signatures
Growing quantum computing capabilities pose a serious and immediate danger to the integrity of digital signatures, which are essential to contemporary secure communication and transactional systems. Elliptic Curve Cryptography (ECC) and RSA are two examples of asymmetric cryptographic algorithms that are widely used in current digital signature techniques. Their mathematical underpinnings, Shor’s algorithm, a quantum algorithm that can effectively factor big numbers and solve the discrete logarithm issue, pose a fundamental threat to these methods. Data signed today using these procedures may be retroactively decrypted and forged once sufficiently powerful quantum computers become accessible, demonstrating that this vulnerability goes beyond simple compromise.
Digital signature market to reach USD 118.88 billion by 2032 from USD 10.80 billion in 2025, a 40.9% CAGR. In response to this threat, NIST is standardizing post-quantum cryptography (PQC), which uses algorithms that resist classical and quantum computer assaults. To protect data integrity and consumer trust, NIST recommends that public and private organizations create quantum-resistant cryptography by 2030. This is because existing digital signature algorithms will become outdated and deemed insecure after that year, requiring system modifications.
SignQuantum’s Dual-Layer Post-Quantum Solution
The Post-Quantum Solution from SignQuantum is a proactive solution to this pressing worldwide issue. The solution’s primary innovation is the synergistic integration of NIST’s primary-recommended post-quantum cryptographic algorithms with the quantum-resistant blockchain technology of QANplatform, which was developed by Quantum Software Solutions, a Qatari technology innovation and research lab under MBK Holding.
Two important issues are addressed by this two-layer method: guaranteeing the legitimacy of the signature and protecting unchangeable proof of timing. Quantum resistance is also necessary for the timestamping process that is essential for determining the sequence of events and avoiding retroactive forging, even when PQC techniques are used for signature authenticity. The blockchain technology from QANplatform becomes crucial in this situation. Quantum-resistant technology was deployed in one EU nation in 2024 by QANplatform, a Linux Foundation member and one of the first 20 members of the Linux Foundation’s Post-Quantum Cryptography Alliance (PQCA).

Technological Underpinnings and Seamless Integration
This integration is the technological cornerstone of the SignQuantum solution. Digital signatures are created and validated using NIST-recommended PQC methods, guaranteeing their legitimacy. The hybrid blockchain architecture of QANplatform is used by SignQuantum to create an unchangeable record of signature production and reduce long-term quantum risk. Using cryptographic primitives that are thought to be safe against known quantum algorithms, such as lattice-based cryptography and other quantum-resistant methods, QANplatform is made to resist attacks from both classical and quantum computers.
With the help of its own virtual machine and consensus mechanism, QANplatform stands out for supporting smart contract capabilities in any programming language. Because of its adaptability, digital signatures may be used in a greater variety of applications and complex audit trails can be created. Because of its hybrid design, the platform balances security, scalability, and energy efficiency by including elements of both proof-of-work and proof-of-stake consensus methods. Crucially, QANplatform is designed to manage high transaction volumes, which is essential for growing to satisfy needs for broad adoption.
Without requiring significant changes to present workflows, the integration process is made to be smooth and acts as an add-on to current e-signature platforms. The software development kit (SDK) and application programming interfaces (APIs) offered by QANplatform make it possible for developers to include the quantum-resistant blockchain capabilities with ease. The technology creates an immutable record that forbids forgery or retroactive alteration by generating a cryptographic hash of the timestamp data and the signed document, which is then stored on the QANplatform blockchain.
Industry Leaders Emphasize Quantum-Safe Future
The significance of this innovation was emphasized by key stakeholders. SignQuantum “addresses a critical global challenge, paving the way for a secure post-quantum era across both the private and public sectors,” according to Sheikh Mansoor Bin Khalifa Al-Thani, MBK Holding’s founder and chairman. The solution’s smooth integration and ability to give businesses a “fast-lane to quantum-safe security without disrupting existing workflows” were emphasized by SignQuantum CEO Nazmath Nazeer.
Co-Founder and CTO of QANplatform Johann Polecsak stressed the importance of integrating a quantum-resistant blockchain with post-quantum digital signatures. He explained that SignQuantum uses the technology because post-quantum digital signature techniques don’t give unassailable trust without a quantum-resistant blockchain platform that can mathematically prove authenticity. The ability of the QANplatform to “not only safeguard, but also handle the large volume of digital transactions coming from SignQuantum” was another point he emphasized.
With its scalable and interoperable solution for businesses looking to future-proof their digital assets, SignQuantum’s introduction represents a significant advancement in safeguarding long-term document integrity in a quickly changing technological context. NIST’s projected deprecation of current digital signature algorithms beyond 2030 highlights the urgency of implementing such solutions, since reliable, quantum-resistant solutions are essential for preserving data integrity and consumer trust.
