MeeSign

An open-source platform for the demonstration of threshold cryptography protocols.

The platform aims to showcase capabilities of threshold cryptography by providing users with an application using which they can run threshold protocols via an easy-to-use graphical interface. The application performs all the supported cryptographic protocols including distributed key generation. Outputs of the protocols are indistinguishable from single-party outputs, yet they require multiple parties to be created.

Platform architecture

The platform consists of client applications running on users' devices, which connect to a server instance facilitating client communication and coordinating threshold cryptography protocols.

Client application

We provide a client application implemented in the Flutter framework, compatible with Android, Linux, MacOS, and Windows platforms.

You can download prebuilt client application or build it from sources:

• Android
• Linux
• MacOS
• Windows
• Sources

In case you prefer to run the client in a VM, you can use our preconfigured image.

Server application

We provide a server application implemented in Rust to which users can connect with client applications. The server is available also as a docker container. For instruction on how to use it see the GitHub repository.

Currently, we do not have a publicly accessible server instance.

CA certificate of the private instance can be found here.
