# Technology

![](img/threefold_parts.png)


ThreeFold delivers the plumbing layer for a better Internet which has the potential to achieve Augmented Collective Intelligence[^1]. We call such a system **Web4**.

> *ThreeFold might be the only platform in the world providing Web4 network, data and cloud capabilities in one system.*

## 3 Required Levels

Together with our partners, we have all the required parts to make it happen on 3 major levels:

### Personal Level

- **Agent Layer**: Every person owns a Personal Digital Assistant (PDA), managing their digital life.
- **Identity Layer**: Strong reputation management, proof of authenticity, a global name system.
- **Intelligence Layer**: Decentralized, personal AI systems for collaboration & augmented intelligence.
- **Transaction Layer**: Fully integrated with Web3 systems and beyond, e.g. mutual credit, etc.


### Infrastructure Level

- **Network Layer**: Redesign of how communication happens with a private and more scalable network layer.
- **Data Layer**: Redesign of how we share, distribute and store data.
- **Serverless Compute Layer**: Allow code to run close to where participants and data are.
- **Cloud Layer**: Run VMs and containers as part of the ecosystem with Web2 compatibility layer.

### Physical Level

- **Routers**: Route between old and new web, and create new secure communication channels.
- **Nodes**: Deliver AI, Data, Compute to the ecosystem.
- **Phones**: Our personal device, capable of building a meshed network, offline support with catchup.
- **Computers**: Any current Linux, Windows, macOS computer seamlessly integrates.

The following are the required components to make all this possible:

- **Zero-OS**: Custom lightweight operating system for nodes built on the Linux kernel.
  - Self-healing and automated resource management via bare metal ThreeFold nodes.
- **Mycelium**: End-to-end encrypted network always using the shortest path.
- **Quantum Safe Storage**: Technology resistant to quantum computer attacks where data can never be lost.
- **Advanced AI Agent**: Creation of apps fully compatibility with Web3. 
- **Smart Contract for IT**: Blockchain-based resource allocation with signed contracts.
  - Secure, transparent transaction mechanisms for deployment of solutions on the ThreeFold Grid.
