ITTI, a Paraguayan provider processing over 40% of the nation’s financial transactions and serving nine of 22 financial institutions regulated by the Central Bank, has entered into an exclusive distribution agreement with SignQuantum, a product of Quantum Software Solutions (a member of MBK Holding), to deliver quantum-resistant security for digitally signed documents across Latin America. This integration leverages SignQuantum’s add-on, designed for seamless compatibility with existing e-signature platforms, utilizing the National Institute of Standards and Technology (NIST)-recommended post-quantum algorithm and QANplatform, a quantum-resistant blockchain-the first to enable smart contract development in any programming language and a member of the Linux Foundation’s Post-Quantum Cryptography Alliance-for immutable time-stamping, thereby addressing vulnerabilities to “time travel” attacks from future quantum computers.
QANplatform’s technology was implemented in one EU country in 2024 and is designed to handle the large transaction volumes of ITTI’s client base, which includes banks, insurance companies, and public sector institutions, anticipating initial implementations shortly as the digital signature market is projected to grow from USD 10. 80 billion in 2025 to USD 118. 88 billion by 2032, exhibiting a 40% compound annual growth rate, and driven by regulatory compliance and remote operations; ITTI received a gold award for its ITTI Secure tool at Fintech Americas 2025 in Miami, and plans to expand its hubs in Argentina, Brazil, and Colombia with offices in three additional countries by the end of 2025, supported by a team of 1,200 professionals.
ITTI and SignQuantum Partnership
ITTI, a Paraguayan digital transformation provider serving the financial sector, has entered into an exclusive distribution agreement with SignQuantum for Latin America, aiming to deliver quantum-resistant security for digitally signed documents. This collaboration addresses the escalating threat posed by advancements in quantum computing to current cryptographic systems, particularly the vulnerability of existing digital signatures to future “time travel” attacks.
ITTI processes over 40% of Paraguay’s financial transactions and serves nine of the country’s 22 financial institutions regulated by the Central Bank, positioning it as a key driver for post-quantum cryptography adoption within the region. The partnership leverages SignQuantum’s self-hosted add-on, designed to seamlessly integrate with existing e-signature platforms, providing a rapid transition to quantum-safe cryptography without disrupting established workflows.
SignQuantum’s solution uniquely addresses the challenges of maintaining digital signature authenticity and securing proof of timing, employing the National Institute of Standards and Technology (NIST)-recommended post-quantum algorithm alongside QANplatform, a quantum-resistant blockchain, for immutable time-stamping. This approach mitigates the risk of retrospective signature forgery enabled by sufficiently powerful quantum computers.
QANplatform, a core component of the SignQuantum solution, is a revolutionary hybrid blockchain platform offering smart contract functionality and unparalleled time to market for Web3 development. As a member of the Linux Foundation and one of the initial members of the Linux Foundation’s Post-Quantum Cryptography Alliance (PQCA), QANplatform’s technology was implemented in one European Union member state in 2024, demonstrating its maturity and real-world applicability.
Johann Polecsak, Co-Founder and CTO of QANplatform, highlighted the significance of this deployment, noting the platform’s capacity to handle the substantial transaction volumes generated by ITTI’s client base. Luis Angulo, Vice President of ITTI, stated that the partnership strategically expands their service portfolio, offering clients the most advanced technologies available and ensuring the secure management of critical documents.
ITTI, employing a team of 1,200 professionals and with established hubs in Argentina, Brazil, and Colombia, anticipates initial implementations of the technology shortly and plans to open offices in three additional countries by the end of 2025. The company’s recent gold award for Digital Banking for Financial Innovators, received for its ITTI Secure tool at Fintech Americas 2025 in Miami, underscores its commitment to innovation and security.
SignQuantum itself is a product of Quantum Software Solutions, a Qatari technology innovation and research lab affiliated with MBK Holding. Nazmath Nazeer, CEO of SignQuantum, emphasized ITTI’s uniquely advantageous position, given its substantial market share within Paraguay’s financial sector.
The global system utilises NIST-approved PQC algorithms, while QANplatform provides an immutable, time-stamped record of signature creation, preventing retroactive modification and ensuring long-term validity.
This layered approach mitigates the risks associated with potential future breakthroughs in quantum computing and provides a robust framework for securing digitally signed documents in an increasingly complex threat landscape. The system’s reliance on established standards and open-source technologies, such as those promoted by the Linux Foundation, further enhances its credibility and facilitates wider adoption.
