Partage: A blockchain-based social network

This is an experiment on developing a blockchain-based social network as part of our project in CS438 conducted at EPFL.

Running the Certificate Authority

To run the certificate authority, navigate to Partage-CA and run the file run.sh.

Running the Client

To run the client, please navigate to Partage-Client/peer/main and run

$ go run main.go -port=PORT -id=ID -i=INTRODUCER_ADDRESS

Here, PORT denotes the port of the frontend, ID denotes the Paxos ID of the client, and INTRODUCER_ADDRESS denotes another node already in the system. The first node in the system will have its INTRODUCER_ADDRESS as an empty string, and an ID of 1. The other nodes can use that node's Partage IP address (displayed at the command line after running the client) as INTRODUCER_ADDRESS and with increasing IDs.

Example

Here is an example for running the system with three nodes. Make sure that the certificate authority is already running in the background. We also assume that the IP address of the node 1 is 127.0.0.1:5738. In your case, you should use the IP address displayed on the console after starting node 1.

Node 1

$ go run main.go -port=8000 -id=1 -i=

Node 2

$ go run main.go -port=8001 -id=2 -i=127.0.0.1:5738

Node 3

$ go run main.go -port=8002 -id=3 -i=127.0.0.1:5738

Then, for example, to navigate to the corresponding frontend of node 1, open 127.0.0.1:8000 in your browser.
