Optalysys Unveils LightLocker Node for Secure blockchain Transactions
Leeds-based Optalysys launched its LightLocker Node on June 16, 2025, a dedicated hardware server designed for confidential blockchain transactions using Fully Homomorphic Encryption (FHE). This innovation addresses the transparency limitations inherent in customary blockchain networks, were all transactions are publicly recorded.
LightLocker node enables the processing of encrypted data directly on blockchain networks, maintaining decentralization while ensuring privacy for sensitive transaction data. the system can handle over 100 encrypted transactions per second, facilitating applications like confidential token transfers and private lending [[3]].
Enhanced Performance and Energy Efficiency
The LightLocker Node consumes 40% less energy than traditional GPU-based systems used for blockchain encryption. This efficiency stems from its design specifically for blockchain encryption, rather than adapting general-purpose computing chips. the server solution also includes modular upgrades and cloud integration, allowing businesses to scale blockchain operations cost-effectively.
Did You Know? Fully Homomorphic Encryption (FHE) allows computations to be performed on encrypted data without decrypting it first.
Current blockchain encryption methods often rely on costly and inefficient GPU systems. Optalysys’ hardware offers a purpose-built alternative for encrypted transaction processing.
Market Applications and Growth Projections
The global blockchain market is projected to reach $248.9 billion by 2029, exhibiting a compound annual growth rate of 65.5% [Statista]. Financial services companies, in particular, face challenges with blockchain transparency due to the sensitive client data they handle.
LightLocker Node facilitates automated market makers and other decentralized finance (DeFi) applications with end-to-end encryption, processing encrypted data without decryption at any point. This is crucial for maintaining privacy in financial transactions [[1]].
Technical Details of LightLocker Node
The hardware utilizes silicon photonics technology to enable FHE processing at scale, addressing performance degradation issues typically associated with encrypted computation. According to Optalysys, LightLocker Node is also quantum resilient, addressing future security concerns related to quantum computing.
Pro Tip: Quantum resilience refers to a system’s ability to withstand attacks from quantum computers, which could perhaps break current encryption methods.
The system maintains blockchain decentralization while adding privacy layers, allowing users to process confidential transactions without compromising the distributed nature of blockchain networks [[2]].
Optalysys Company Background
Optalysys, co-founded in 2013 by CEO Dr. Nick New and CTO Robert Todd, has secured funding from Northern Gritstone, Lingotto, Verve ventures, and imec.xpand. The company completed a £21 million Series A funding round in July 2023, focusing on processing encrypted data at scale without decryption requirements.
LightLocker Node is the first product in Optalysys’ planned product roadmap, positioning the company as an enabler of secure computing through advanced encryption hardware.

Blockchain Technology: An Overview
Blockchain technology, at its core, is a distributed ledger system that records transactions across multiple computers. This decentralized nature enhances security and transparency, as each transaction must be verified by multiple nodes on the network Gemini. The technology has evolved significantly as its inception, with applications now spanning various industries, including finance, supply chain management, and healthcare.
The increasing adoption of blockchain is driven by its potential to streamline processes, reduce costs, and improve data security. As more businesses and organizations explore the benefits of blockchain, innovations like the LightLocker node are crucial for addressing specific challenges, such as privacy concerns in financial transactions.
