- Optalysys launches LightLocker Node, the first dedicated hardware server for confidential blockchain transactions using Fully Homomorphic Encryption
- The system processes over 100 encrypted transactions per second while maintaining complete privacy and decentralization
- LightLocker Node uses 40% less energy than traditional GPU-based systems for blockchain encryption
- The hardware enables confidential token transfers, private lending, and automated market makers without decrypting data
- The global blockchain market is projected to reach $248.9 billion by 2029 with 65.5% annual growth rate
Optalysys has released LightLocker Node, marking the first dedicated enterprise-grade server designed specifically for confidential blockchain transactions. The Leeds-based company announced the launch on June 16, 2025, positioning the hardware as a solution to blockchain’s transparency limitations.
Traditional public blockchain networks record all transactions transparently, making wallet activity visible to anyone. This creates challenges for businesses handling sensitive financial data or proprietary information.
LightLocker Node uses Fully Homomorphic Encryption (FHE) technology to process encrypted data directly on blockchain networks. The system maintains blockchain’s decentralized structure while adding privacy protections for transaction data.
The hardware can process more than 100 encrypted transactions per second according to Optalysys specifications. This performance level supports real-world applications including confidential token transfers and private lending operations.
Performance and Energy Efficiency
LightLocker Node consumes 40% less energy than traditional GPU-based systems used for blockchain encryption. The company designed the hardware specifically for blockchain encryption rather than adapting general-purpose computing chips.
The server solution includes modular upgrades and cloud integration capabilities. These features allow businesses to scale their blockchain operations without proportional cost increases.
Current blockchain encryption relies heavily on GPU systems that Optalysys describes as costly and inefficient. The company’s hardware offers an alternative designed specifically for encrypted transaction processing.
Market Context and Applications
The global blockchain market is expected to reach $248.9 billion by 2029. This represents a compound annual growth rate of 65.5% as companies build infrastructure for broader adoption.
Financial services companies face particular challenges with blockchain transparency. Many handle sensitive client information that cannot be processed on traditional public blockchains.
LightLocker Node enables automated market makers and other decentralized finance applications to operate with end-to-end encryption. The system processes encrypted data without requiring decryption at any point.
Technical Specifications
The hardware uses silicon photonics technology to enable FHE processing at scale. Optalysys developed this approach to handle encrypted computation without performance degradation.
LightLocker Node is quantum resilient according to the company’s specifications. This design addresses future security concerns as quantum computing develops.
The system maintains blockchain decentralization while adding privacy layers. Users can process confidential transactions without compromising the distributed nature of blockchain networks.
Company Background
Dr. Nick New serves as CEO of Optalysys, which he co-founded in 2013 with CTO Robert Todd. The company has raised funding from Northern Gritstone, Lingotto, Verve Ventures, and imec.xpand.
Optalysys completed a £21 million Series A funding round in July 2023. The company focuses on processing encrypted data at scale without decryption requirements.
LightLocker Node represents the first product in Optalysys’ planned product roadmap. The company positions itself as enabling the future of secure computing through advanced encryption hardware.
