QuantumGate is a peer-to-peer (P2P) communications protocol, library and API. The long-term goal for QuantumGate is to become a platform for distributed computing based on a mesh networking model. In the short term, the goal is to provide developers with networking technology that they can easily integrate and use in their own applications. Click here for a more detailed overview.


This software is currently in alpha development stage. It has not yet undergone peer review and no security audits have yet been done on the cryptographic protocol and its implementation. The API may also change, and while big changes are unlikely it will receive small updates as development progresses. Feel free to use and experiment with this software in your own projects, but keep the above information in mind.


Based on the architecture described in the overview, the following main features are not yet implemented:

  • DHT functionality
  • Database functionality


QuantumGate is developed in C++17 and currently only supports the Microsoft Windows (x86/x64) platform. Support for Linux is planned for the future.


You'll require the latest version of Microsoft Visual Studio 2017, as well as the dependencies listed below. When the paths to the dependency includes and libraries have been configured properly, building is as simple as opening the QuantumGate.sln file in the project root with Visual Studio and issuing the build command for the entire solution.


QuantumGate Core Library

Name Version
Microsoft Guideline Support Library Latest.
OpenSSL At least 1.1.1
PCG-Random Latest.
zlib At least 1.2.11
Zstandard At least 1.3.4

QuantumGate Test Applications/Extenders

Name Version
Monocypher Latest.
JSON for Modern C++ At least 3.2.1


The QuantumGate MSVC project is configured to look for specific naming of the OpenSSL, zlib and Zstandard .dll and .lib files, depending on the platform (32 or 64 bit) you're building for. You may have to build these libraries yourself to specify the names, or, alternatively you may change the names in the source code and configuration to the ones you use.

Library x86 Debug x86 Release x64 Debug x64 Release
OpenSSL libcrypto32d.lib, libcrypto32d.dll libcrypto32.lib, libcrypto32.dll libcrypto64d.lib, libcrypto64d.dll libcrypto64.lib, libcrypto64.dll
zlib zlib32.lib, zlib32.dll zlib32.lib, zlib32.dll zlib64.lib, zlib64.dll zlib64.lib, zlib64.dll
Zstandard zstd32.lib, zstd32.dll zstd32.lib, zstd32.dll zstd64.lib, zstd64.dll zstd64.lib, zstd64.dll
