AI on Blockchain

Overview

The project provides a distributed hand writing recognition serivce running on Ethermint.

With the client node processes user's image with the first few layers of CNN, the service node then continue analyzes the processed data with the rest layers (full connnected layers).

It aims at protecting data privacy since service node cannot get access to the original data while the customer cannot obtain the whole analyze model.

The result looks like this. You can trace the service process on the console of right side and receive the result.

Deployment

1. Environment

   OS: Linux / Mac OS / Windows (under experiment)

   Docker: The entire project is wrapped in Docker containers.

2. Deploy

   • Build Docker Images

     In directory named 'AI on Ethermint'

     docker build -f ethermint/Dockerfile -t bianjie_ethermint ./ethermint
     docker build -f bean-hwr-server/docker/Dockerfile -t bean-hwr-server ./bean-hwr-server
     docker build -f bean-hwr/docker/Dockerfile -t bean-hwr ./bean-hwr

   • Run the project!

     bash run.sh

     Then you will see echo message

     service running on http://localhost:8080
     

     And the service is successfully running on http://localhost:8080

     You can type "docker ps" and then you shall see five containers:

   • Terminate the service

     bash terminate.sh

   • Enjoy!
