Below is what I found about the Mycelium developers and the project itself (its goals, architecture, and status).


👤 Who is behind Mycelium — developers and initiators

  • Mycelium is developed by ThreeFold (ThreeFold Tech / ThreeFold Grid).

  • In official announcements, a contributor named Lee Smet is mentioned as leading the effort to build a new IPv6 overlay network.

  • The project is open-source, with the repository hosted on GitHub.

ThreeFold is an organization promoting decentralized networks and infrastructure. Mycelium is a component of their ecosystem — not a third-party plugin, but a native project.


🛠 What is Mycelium — architecture and key properties

Mycelium is:

  • An IPv6 overlay network written in Rust.

  • When joining, each node receives an IPv6 address from the 400::/7 range.

  • All connections are end-to-end encrypted; each node has a public/private key pair, and its network address is cryptographically tied to the private key.

  • The network is locality-aware — routing chooses optimal paths with minimal latency.

  • It supports multiple transport protocols: TCP, QUIC, etc.

  • Routing is inspired by (or partially based on) the Babel routing protocol.

  • Mycelium can operate without a TUN interface (as a message bus only) for lightweight encrypted data exchange.

  • The repository includes a message-system layer enabling encrypted messaging above the network layer.


📡 Project goals, design, and future direction

  • Mycelium aims to deliver a secure, efficient and scalable alternative to the traditional Internet with focus on privacy, decentralization, and resilience.

  • It is designed as part of the wider ThreeFold Grid ecosystem — serving as the network backbone for their services.

  • The developers target planet-scale scalability.

  • Mycelium is positioned not only as a private networking solution, but as infrastructure for many scenarios: secure P2P communications, self-hosting, IoT networking, decentralized services, cloud infrastructures, CDN-like usage, etc.

  • As of 2024–2025, Mycelium remains under active development — scaling is a key focus.


✅ Status, implementation and limitations

  • Mycelium is operational with builds available for Linux, macOS, Windows; iOS and Android are planned / in beta.

  • Documentation claims support for up to ~100,000 nodes within a single network.

  • Planned improvements include: enhanced resilience, NAT support, QUIC hole-punching, protocol expansion, easier deployment.

  • Mycelium is an actively maintained open-source project under the Apache-2.0 license.


🔎 Summary — strengths and potential risks

Strengths:

  • High-level security and privacy: true E2E encryption and crypto-bound addressing.

  • Decentralization — no single point of control.

  • Flexible: full IPv6 network or lightweight encrypted message bus.

  • Suitable for many use cases: private networking, P2P, IoT, remote work, decentralized services, private Internet access.

Limitations / risks:

  • Still maturing — global scaling goal remains unproven.

  • P2P overlay networks always depend on trust and correct configuration of peers.

  • Unclear real-world adoption and number of active nodes — affects reliability.

  • Some external services may still see public exit IP addresses (e.g., through NAT), which may reduce anonymity in practice.


If you want, I can check live network metrics — number of active nodes, adoption level, known issues, etc.
