D-COS NEXUS
INTEGRATED MODULAR TECHNOLOGY ECOSYSTEM
Cross-platform · Windows · macOS · Linux
D-COS NEXUS is a software platform for Windows, macOS and Linux that brings together, in a single program, 36 modules for security, intelligence, finance, automation and everyday work. It runs on your own computer: your data stay with you, encrypted when the program is closed.
- 36 integrated modules, one executable
- M01 Core: local Root of Trust
- Data and keys stay on your system
- For companies, institutions and partners
The ecosystem in numbers (official V130 MASTERWORK documentation)
INTERNATIONAL TECHNOLOGY IDENTITY
An international technology identity
D-COS NEXUS is a proprietary technology ecosystem with an international vision: its own architecture, data sovereignty and interoperability, for companies and institutions in every market.
Technological sovereignty
It runs locally: data, keys and decisions stay on the customer's system.
Proprietary architecture
36 modules integrated in a single executable, with M01 Core as Root of Trust.
Interoperability
Verifiable contracts between modules and standard formats towards the tools already in use.
Research and innovation
Continuous, documented development with transparently declared statuses.
Global vision
Official documentation and website in 6 languages; Windows, macOS and Linux.
Verifiable trust
Ed25519-signed licences verified locally and a SHA-256 audit trail.
D-COS NEXUS
An ecosystem, not a collection of apps
All modules belong to one ecosystem. They are not separate products: you install one program, dcos.exe, and your licence decides which modules are switched on. The modules share the same protections, the same permissions and the same way of asking for your approval.
One shared core
M01 Core & Foundation is the Root of Trust: routing, supervision, licensing and encrypted vault for every module.
Native integration
Modules exchange data and capabilities through stable contracts rather than after-the-fact integrations.
Declared transparency
The real level of each module is published: operational, hardware-ready or simulation.
What it is for
What it is for
- Keep an eye on the security of your computer and investigate incidents.
- Analyse data: real estate deals, sales, logistics, research measurements, recorded signals.
- Organise work: e-mail, accounting, workflows, daily planning.
- Prepare and simulate activities safely before doing them for real: trading strategies, drone missions, radio links.
Problems it helps to solve
Problems it helps to solve
Scattered tools
one console instead of many separate programs.
Loss of control
nothing with real effects happens without your permission; sensitive actions need your signed approval.
Unclear results
every module tells you honestly whether a result is measured, estimated, simulated or not available.
Data exposure
data are processed locally and encrypted at rest.
Manifesto
Cognition is persistent. Computation is migratable. Embodiment is interchangeable. Safety is local.
Technology vision
Technology vision
A system that remembers, reasons over time and can move its computation where it is needed, without ever giving up control of safety. Logic is decoupled from hardware: the same core can inhabit a PC, a connected home or an edge node.

Modular architecture M01–M36
Five macro-areas, six pillars, thirty-six modules. Explore the interconnection map and each module's sheet, with implementation status and declared limits.
Key capabilities
Key capabilities
Verifiable trust
Ed25519-signed releases, SHA-256 fingerprints, chained forensic log.
Persistent memory
Knowledge graph with provenance and versions, Chronos causal timeline.
Local defence
Host diagnostics, defensive threat intelligence, network resilience.
Intelligence with provenance
GEOINT, satellites from public data, OSINT from authorised open sources.
Productivity & business
Office and finance, logistics, real estate, commercial analytics, design.
Edge & devices
Telemetry, permission-based smart home, resource optimisation.
The six technology pillars
The six technology pillars
Trust & Integrity
Every component starts from a trust core: signed licences, verifiable releases, tamper-evident logs.
02Cognition, Memory & Time
Cognitive continuity: persistent memory with provenance, causal timeline, reproducible knowledge.
03Cyber Defence & Resilience
Local, defensive security: diagnostics, game theory, network resilience, institutional authorisation.
04Intelligence & Situational Awareness
Understanding context: geospatial data, open sources, aerospace, naval and radio domains.
05Interchangeable Bodies & Edge
The same core can inhabit different devices: PC, home, sensors, peripherals. Computation moves where it is needed.
06Business & Productivity
Operating capabilities for work and enterprise: office, finance, logistics, growth, design, careers.
Transparency note: the project documentation defines five ontological pillars (identity, memory, goals, temporal world model, interchangeable bodies) and a …
Details
… product taxonomy of four macro-areas plus system utilities. The six pillars shown here are an editorial classification grouping the 36 modules by purpose; they do not replace the official classifications, which remain available in the Architecture filters.
Applications
Applications
Six communication areas, each with its relevant capabilities and modules.
Government & Public Sector
Public bodies and administrations that must handle information traceably and under control.
Business & Enterprise
Companies, SMEs and groups that want integrated operating capabilities on a single secure base.
Critical Infrastructure & Industry 4.0
Infrastructure and industry needing resilience, telemetry and separation between logic and hardware.
Security, Defence & Intelligence
Organisations with security and analysis needs, in a strictly defensive approach.
People & Everyday Life
Individuals and professionals who want an assistant that remembers, organises and respects their privacy.
Universities & Research
Universities and research centres interested in reproducible computation and in an architecture to study.
Security & technology sovereignty
Security & technology sovereignty
Safety is local by principle: data stays encrypted on your devices, the default language model runs locally, and no action with real-world effects starts without a signed human authorisation.
- Local, offline execution by default
- Proposal ≠ execution: effectful actions stay NOT_EXECUTED until approved
- Encrypted data at rest and signing keys kept offline
- No protection function behind a licence
M01 · Root of Trust
M01 Core — the trust core
The heart of D-COS NEXUS: it starts the system, checks licences and protects every other module.
- Licence verification and module unlocking
- Knowledge store, decisions, actions and workflows
- Signed human supervision of sensitive actions
- Protection of keys, customer identities and the internal event bus
The configuration of M01 as Root of Trust is a precise and deliberate engineering choice of the offline-first architecture: a single local trust authority, with signing keys kept offline, that does not depend on remote services.
M01's “partially implemented” status reflects a deliberate company and design philosophy: M01 evolves incrementally, not as a rigid monolithic block, to ensure granular and complete operational flexibility.
Discover M01Cross-platform: Windows, macOS and Linux
Cross-platform: Windows, macOS and Linux
D-COS NEXUS is a cross-platform ecosystem with official support for Windows, macOS and Linux. Its code, written in Python, handles the differences between operating systems, and an official build pipeline produces a dedicated package for each platform.
Windows 10/11 (x64)
Signed executable dcos.exe with the Python and Visual C++ runtimes included. Package acceptance test 24/24.
macOS (Apple Silicon and Intel)
Official packages for macOS ARM64 and x64 produced by the build pipeline. Laboratory testing and Apple notarisation still to be completed.
Linux (x64 and ARM64)
Official packages for Linux x64 and ARM64 and a systemd service for servers and mini-PCs. Laboratory testing still to be completed.
Docker · NAS · Raspberry Pi 4/5
Dockerfile and docker-compose for PCs, NAS, mini-PCs and Raspberry Pi 4/5.
Smartphones and tablets
HTTPS console usable from the browser of phones and tablets, already tried. Running on Android through Termux is set up.
Each PyInstaller build only runs on the system it was built for, so every platform has its own package.
Details
Some functions use Windows services: outside Windows the vault opens with the recovery passphrase (scrypt) instead of DPAPI, and automatic device detection (Plug and Play) is available on Windows only.
