Optalysys launches world’s first dedicated hardware solution for confidential blockchain transactions
Leeds, 16th June 2025: Optalysys, a company enabling the future of secure computing, has launched the world’s first dedicated enterprise-grade server for blockchain — LightLocker™ Node, designed to enable Fully Homomorphic Encryption (FHE) and ensure complete confidentiality on any transaction.
Traditionally, public blockchain transactions are fully transparent, meaning all activity between wallets is visible and recorded — a significant challenge for industries handling sensitive information such as financial services. LightLocker Node allows encrypted data to be processed directly on blockchain without decryption. It maintains the decentralisation that blockchain offers, while adding the confidentiality, performance and scalability required for widespread enterprise adoption of FHE.
With the ability to process over 100 encrypted transactions per second, LightLocker Node provides the performance needed to efficiently support real-world use cases such as confidential token transfer, private lending and automated market markers (AMMs), where true end-to-end encryption is becoming a critical requirement.
The global blockchain market is projected to reach $248.9 billion by 2029 at a compound annual growth rate (CAGR) of 65.5%, as companies develop infrastructure for widespread adoption. Optalysys’ LightLocker Node is purpose-built for blockchain encryption, offering an alternative to the current reliance on costly and inefficient GPU-based systems. Its modular upgrades and cloud integration enable businesses to scale blockchain operations without increasing costs.
Available as a complete server solution, LightLocker Node uses 40% less energy than traditional GPUs, offering a secure, scalable, cost-effective and energy-efficient alternative for the next-generation of encrypted blockchain infrastructure. It is the first product to be launched in Optalysys’ product roadmap.
Dr Nick New, CEO of Optalysys, said: “Blockchain has the potential to underpin not just the future of financial services, but the next generation of the internet itself. However, its lack of confidentiality has held it back from widespread enterprise adoption, especially in financial services. For blockchain technologies to be adopted at scale, infrastructure that supports confidential computing is essential. Traditional hardware solutions for encrypted blockchain are costly and inefficient. General-use chips are also not designed for the specific requirements of encrypted transaction processing. LightLocker Node, Optalysys’ dedicated FHE hardware for blockchain, addresses this problem. It is quantum resilient and enables secure, confidential data processing directly on the blockchain, without impacting performance.“
