PrimiHub is a platform that supports Multi-Party Computing(MPC), Federated Learning, Private set intersection (PSI), and Private Information Retrieval (PIR) features, and supports extensions of data source access, data consumption, access application, syntax, semantic and security protocols. For details, see PrimiHub core feature.

Run an Multi-Party Computing application in 5 minutes

Install docker and docker-compose

Download the docker-compose file:

curl https://get.primihub.com/release/1.3.9/docker-compose.yml -s -o docker-compose.yml

Start three docker containers using docker-compose. The container includes: one simple bootstrap node, three nodes

docker-compose up -d

or, you could specific the container register and version, such as:

REGISTRY=registry.cn-beijing.aliyuncs.com TAG=1.4.0 docker-compose up -d

Check out the running docker container

docker-compose ps

Let three nodes jointly perform a logistic regression task of multi-party secure computation (MPC)

docker run --network=host -it primihub/primihub-node:latest ./primihub-cli --server=127.0.0.1:8050

💡 The node response the task

You can request computing tasks from any node in the computing cluster

💡 Available task parameters

The following parameters can be specified through primihub-cli:

1. Which node is requested to start the task.
2. Which shared datasets are used.
3. What kind of private computing tasks to do.

In this example, primihub-cli will use the default parameters to request an ABY3 tripartite logistic regression test task from node 0. For the parameters that can be specified by cli, please refer to Create task
