Luxembourg deep tech
Zetako develops technologies for organizations that need to compress, verify and control data across constrained devices, private infrastructure and secure collaboration 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
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.
Lossless IoT data compression for structured sensor, telemetry and metering payloads.
Built for constrained devices, gateways and edge systems where bandwidth, memory, CPU and energy are limited.

Built for organizations that cannot fully outsource trust to external collaboration platforms.
Open ZNodeCheck GitHubA 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.
Open ZCapsCheck GitHubBlockchain-native lossless compression with negotiated models for structured chain data paths.
Built for Ethereum, Solana, Cosmos, archive, RPC and validator-adjacent infrastructure paths.
Open ZChainCheck GitHubResearch stack
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.
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
ZNano is Zetako's lossless IoT compression solution for structured sensor payloads, telemetry and metering data. It is designed for constrained devices and edge systems where bandwidth, memory, CPU and energy are limited, while keeping integrity verifiable through SHA256-based demo workflows.
ZNode
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.
ZCaps
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.
ZChain
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.
Sovereignty
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
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.
