Bringing LLMs to Klave AI: Secure, Scalable, Sustainable | Klave Newsletter April 2025
NEWS
Extending Klave AI with LLMs.
Set to bring true privacy and trust to artificial intelligence. (Read on)
We missed our March edition, but with good reason. We were occupied with the biggest critical infrastructure tender application we’ve ever taken on!
Let’s catch you up on what’s been happening.
Bank of International Settlements (BIS) Innovation Hub Analytics Challenge Winners
A few weeks ago, Secretarium and FutureFlow were honoured with the BIS Innovation Hub Analytics Challenge 2025 award for sharing data and intelligence while preserving user privacy.
This recognition builds on our momentum, following our G20/BIS TechSprint 2023 win and several other accolades, it reinforces the continuity of our leadership in securing data within the financial sector.
At Secretarium, we specialise in protecting data at rest, in transit, and in use, using confidential computing and privacy-enhancing technologies. Even in collaborative, multi-organisation environments, our solutions guarantee that sensitive data remains private and secure at all times.
If you’re interested in how our technology can be applied to your use cases, please feel free to reach out.
The Future of Finance: We’re Building It
The next generation of national payment systems is taking shape, and we are proud to be at the forefront of designing new payment schemes capable of serving entire populations. Our mission is to build modern, efficient, privacy-preserving and secure financial infrastructure that can scale to support hundreds of millions of users.
Our work with initiatives like the Bank of England’s Digital Pound project highlights the critical role privacy and security must play in any future financial systems. We are applying our expertise in privacy-enhancing technologies to ensure that innovation never comes at the expense trust.

Confidential Computing: A New Era in Digital Asset Security
We've been working hard to spotlight the power of confidential computing for digital asset signing. By leveraging hardware-based Trusted Execution Environments (TEEs), we create dedicated, tamper-resistant enclaves which remain fully isolated from the operating system and hypervisor, ensuring unmatched levels of security and privacy.
Recently, we built a secure Rust application leveraging the ecosystem of web3 libraries such as Alloy, alongside the Klave Rust SDK. Deployed on Klave, the code compiles into WebAssembly and runs inside a secure enclave, guaranteeing trustless execution every step of the way.
As part of a recent proof of concept with Intellect EU, we demonstrated how Klave’s confidential computing technology can integrate into broader ecosystems. By connecting with Intellect EU’s Catalyst Blockchain Manager, we enable enterprises to securely execute transactions with exclusive access to their wallets.
You can read the full story and technical deep dive on the Intellect EU Blog.

Building Attestable Apps with Klave and WebAssembly
Our Head of Platform, Étienne Bossé, took to the stage at Wasm I/O, to share how Klave is bringing honest computing to the WebAssemby (WASM) ecosystem.
Missed the event? Don’t worry, you can watch Étienne's talk on YouTube! In his talk, he explored how a unified architecture combining WASM, Trusted Execution Environments (TEEs), and Distributed Ledger Technology (DLT) can be deployed across the cloud-edge continuum, ensuring confidentiality, integrity, and verifiability of both code and data at all times.
WebAssembly brings key advantages: its lightweight and fast execution enables near-native performance with no cold starts, and its built-in sandboxing model adds an extra layer of isolation and safety. When combined with TEEs, this results in a "sandbox within a sandbox" model, allowing for high-density multi-tenancy within secure enclaves without compromising security.
By making confidentiality, integrity, and verifiability native to the compute layer, it opens the door to a new generation of applications that can run anywhere, from cloud to edge, without ever compromising trust.
TECH
Klave Release
We're rolling out our brand new Klave v3.3 update that enhances security, performance, and developer capabilities. Here are some of the key features:
Upgrade to Intel SGX 2.25 across all Klave clusters for the latest and most secure Trusted Execution Environment (TEE) support.
Enhance RPC enclave-to-enclave communication, enabling seamless access to components like LLMs and database engines running within enclaves.
Attestation features now exposed in SDKs – developers can now use Get Quote and Verify Quote for SGX-based attestation.
Upgraded SDKs – added HMAC management in the Cryptographic SDK and improved functionality in the Ledger SDK.
Klave AI: Lightweight, Private and Secure
We’re proud to extend Klave AI with LLMs. Powered by Confidential Computing, Klave AI brings true privacy and verifiable trust to artificial intelligence. It secures sensitive models, data, and interactions inside tamper-proof enclaves, ensuring nothing is exposed, not even to the platform itself.
Our goal is to simplify the usage of LLMs for AI Agents, and as usual, we want to engineer it in a way that keeps the energy footprint under control. Two weeks ago, Microsoft released BitNet b1.58 2B4T, a highly quantised LLM that maintains performance comparable to leading open-weight, full-precision models, while dramatically reducing energy, latency, and memory footprints. BitNet fits perfectly into Klave’s vision for efficient, secure AI.
Our first release highlights:
Lightweight and energy-efficient, using the great cpp library
Private by design, with full end-to-end encryption
Deployment ready, across any cloud or on-premises
While most AI systems are heavy and resource-intensive, Klave AI shows that confidential AI can be secure, scalable, and sustainable from day one.
We will be launching the LLM template in May 2025 and opening a new chapter for privacy-first AI Agents. Our efforts are currently on turning Klave into a Model Context Protocol (MCP) compliant platform, simplifying the connection of AI Agents to private data.

Klave is the Future of Distributed Ledgers
At the core of Klave is Secretarium’s Secure-Enclave Distributed Ledger Technology (SDLT). It brings a new level of performance, privacy and integrity to distributed systems by using Confidential Computing.
SDLT marks a fundamental evolution in distributed ledger architecture, by embedding Trusted Execution Environments (TEEs). This combination of hardware-based security with ledger integrity redefines what’s possible in terms of unlocking trust, performance, and interoperability like never before.
Highlights of SDLT
Fast data distribution through a log-based architecture
BFT RAFT consensus running inside TEEs
Remote attestation for code and data verification
Support for public, private or permissioned networks
Encrypted data at rest, in transit and in use
Native connectivity with Web2 and Web3 systems
Already trusted by institutions like the Bank of England, Thales and leading financial firms, SDLT is designed for secure, high-performance systems that demand continuous availability and end-to-end privacy.
Reach out to discover how SDLT can support your use cases.

Enhancing MuSig2 Protocol with Klave
Written by Nicolas Marie, Head of Product at Secretarium.
Multisignature (MuSig) protocols are essential for secure, collaborative control over operations. In our latest article, we explore how MuSig2, a next-generation multi-signature offering, significantly improves efficiency, privacy, and security.
By integrating MuSig2 with Trusted Execution Environments (TEEs) on the Klave platform, we enable secure execution, reduced communication complexity, and increased resilience for decentralised applications.
Coming soon to the Klave Template Library: a ready-to-use MuSig2 template that streamlines the development and deployment of secure multisignature applications.
