ZNano
Lossless compression for constrained devices, MCU-class environments, telemetry, sensors and edge systems.
Built for environments where bandwidth, memory, CPU and energy are limited.
Open ZNanoLuxembourg 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: compression, verification, secure communication, ZCaps compression and infrastructure sovereignty.
ZNode
Secure workspace infrastructure for private communication, files, meetings, governance and auditability.
Built for organizations that cannot fully outsource trust to external collaboration platforms.
Open ZNodeZCaps
100% lossless symmetric bit-per-bit compression with deterministic encode/decode and SHA256 verification.
Built to compress at bit level, reconstruct the exact original input, and verify integrity through SHA256 metadata.
Open ZCapsZChain
Compression and verification technology for ledgers, blockchain systems and verifiable data infrastructure.
Built for systems where data reduction, traceability and proof of integrity must coexist.
Open ZChainResearch stack
One foundation. Four product directions.
The same technical foundation appears across the product lines: ZNano brings compression to constrained devices, ZCaps explores 100% lossless symmetric bit-per-bit compression, ZChain applies verification to ledger infrastructure, and ZNode extends the sovereignty principle into secure communication and private workspace infrastructure.
From MCU payloads to bit-level ZCaps compression, Zetako's compression research is designed for exact reconstruction and controlled environments.
Integrity checks and verifiable outputs are treated as product concerns, not afterthoughts.
ZNode extends the research stack into private collaboration, meetings, files and governance workflows.
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
100% lossless compression, bit by bit.
ZCaps is Zetako's proprietary symmetric bit-per-bit compression line. It encodes data through a reversible bit-level workflow and decodes it back into a bit-identical reconstruction of the original input.
The compressed result carries ZCaps compression metadata including method, profile, original size, payload size and SHA256 integrity hashes, making every output inspectable, reversible and verifiable.
- 100% lossless compression
- Symmetric bit-per-bit compressor
- Bit-identical reconstruction
- Deterministic encode/decode
- Reversible workflow
ZChain
Verification and compression for ledger infrastructure.
ZChain applies Zetako's compression and verification research to ledgers, blockchain systems and verifiable data infrastructure.
It is designed around the idea that distributed systems need both smaller data structures and stronger integrity guarantees.
- Ledger-oriented compression
- Verification workflows
- Blockchain data structures
- Traceability and integrity
- Verifiable infrastructure research
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.
- Private deployment models for sensitive workflows.
- Reduced dependency on unnecessary cloud exposure.
- Verification and integrity designed into the product layer.
- Technology spanning embedded devices, private networks, ledgers and organizational infrastructure.
- Control over the systems that carry confidential work.
