Luxembourg deep tech

Sovereign deep tech, built from original research.

Zetako develops proprietary technologies for organizations that need to compress, verify and control data across constrained devices, private infrastructure and secure communication systems.

Founded as a research-driven deep tech lab, Zetako has been building its core technology stack since 2016. Today, that research is deployed through four focused product lines: ZNano, ZNode, ZCaps and ZChain.

Our partners

Zetako's work has developed across deep tech, IoT and infrastructure ecosystems, with participation in recognized programmes and collaborations across embedded, connectivity and enterprise environments.

Product lines

Four products built from one research stack.

Zetako's products are not separate experiments. They are focused product lines built from the same research foundation: embedded telemetry compression, deployable lossless compression, blockchain-native data reduction and sovereign workspace infrastructure.

01 / EMBEDDED COMPRESSION

ZNano

Lossless compression for structured telemetry, metering and constrained embedded systems.

Built for environments where bandwidth, memory, CPU and energy are limited.

02 / SOVEREIGN WORKSPACE

ZNode

Secure workspace infrastructure for private communication, files, meetings, governance and auditability.

Built for organizations that cannot fully outsource trust to external collaboration platforms.

03 / DEPLOYABLE LOSSLESS COMPRESSION

ZCaps

A deployable lossless compression product based on adaptive contextual prediction and statistical entropy coding.

Already used inside ZNode for controlled compression workflows, with ongoing R&D for optimization.

04 / BLOCKCHAIN-NATIVE COMPRESSION

ZChain

Blockchain-native lossless compression with negotiated models for structured chain data paths.

Built for Ethereum, Solana, Cosmos, archive, RPC and validator-adjacent infrastructure paths.

Research stack

One foundation. Four product directions.

The same technical foundation appears across the product lines: ZNano brings compression to constrained devices, ZCaps provides deployable lossless compression for controlled workflows, ZChain applies compression to blockchain infrastructure, and ZNode extends the sovereignty principle into secure communication and private workspace infrastructure.

Compression

From MCU payloads to bit-level ZCaps compression, Zetako's compression research is designed for exact reconstruction and controlled environments.

Verification

Integrity checks and verifiable outputs are treated as product concerns, not afterthoughts.

Secure communication

ZNode extends the research stack into private collaboration, meetings, files and governance workflows.

Sovereign deployment

Products are designed for organizations that need control over infrastructure, data location and operational exposure.

ZNano

Compression where every byte matters.

ZNano is Zetako's embedded compression line for constrained devices and edge systems. It is designed for environments where bandwidth, memory, CPU and energy are limited, while keeping integrity verifiable through SHA256-based demo workflows.

  • MCU-class environments
  • IoT sensors and telemetry
  • Edge and LPWAN deployments
  • Lossless compression workflows
  • Verification-oriented demo flow

ZNode

A sovereign workspace for controlled teams.

ZNode is Zetako's secure infrastructure line for private communication, meetings, files, workspaces, admin controls and compliance workflows.

It exists because sensitive collaboration should not always depend entirely on external platforms when auditability, deployment control and data ownership matter.

  • Secure messaging
  • Meetings and workspaces
  • Files and controlled collaboration
  • Admin governance
  • Compliance and audit trails
  • Private deployment

ZCaps

Deployable lossless compression for controlled systems.

ZCaps is Zetako's lossless compression product based on adaptive contextual prediction and statistical entropy coding. It is already used inside ZNode for controlled compression workflows.

The research continues through Balanced, Fast and Max optimization tracks, while the product layer remains focused on exact byte-for-byte recovery, reliability and integration into sovereign systems.

  • Deployable lossless compression product
  • Integrated into ZNode workflows
  • Adaptive contextual prediction
  • Statistical entropy coding
  • Byte-for-byte reconstruction

ZChain

Blockchain-native compression for infrastructure data paths.

ZChain applies Zetako's lossless compression research to blockchain payloads where the runtime already knows the serialization family being processed.

Its public evidence covers negotiated models, Ethereum/Reth, Solana RPC, CometBFT, Agave and model maturity boundaries for supported, adapter-ready and research paths.

  • Negotiated blockchain models
  • Ethereum and Solana evidence
  • RPC and archive payloads
  • Exact reconstruction
  • Model maturity boundaries

Sovereignty

Sovereignty is not a slogan. It is an architecture choice.

For sensitive organizations, sovereignty means knowing where data is processed, how it is verified, who controls the infrastructure and which external platforms are truly necessary.

Zetako builds product lines for this reality: compression that can run on constrained devices, communication infrastructure that can be privately deployed, ZCaps compression for exact reconstruction, and verification layers designed to preserve integrity.

Research

Built from deep tech R&D since 2016.

Zetako began as a research-driven deep tech lab focused on proprietary compression and data technologies. Since 2016, the work has evolved into a broader sovereign technology stack covering compression, verification, constrained systems, secure communication, ZCaps compression and private infrastructure.
