Gradecoin

Gradecoin is a undergraduate level cryptography simulation/game that masquerades as a cryptocurrency.

The project is live at https://gradecoin.yigitsever.com.

# Read the documentation
$ cargo doc --open

The executable main needs the /templates, users and blocks folders. It also expects a secrets/gradecoin.pem file with the private key of the system.

Running Locally

Create RSA keys:

$ mkdir secrets
$ cd secrets
$ openssl genrsa -out gradecoin.pem 2048
$ openssl rsa -in gradecoin.pem -outform PEM -pubout -out gradecoin.pub

Use gradecoin.pub file in your client program.

Create students list: students.csv should be in the following form:

User ID, Password
e123456,register_password
e123456,register_password

First line is ignored.

Run the server:

$ cargo run

The server should be up on localhost:8080. We recommend using Nginx to reverse proxy Gradecoin so it can be served as HTTPS.

The default config file is config.yaml. You can specify another config file with:

$ cargo run another_config.yaml

You can even run multiple networks at once by giving multiple configuration files:

# Run both the main network (at /) and testnet (at /testnet)
# For example, register for main network at `localhost:8080/register`,
# testnet network at `localhost:8080/testnet/register`
$ cargo run config.yaml testnet.yaml

In the config file, url_prefix field determines the address of the network.

You can clear the database for all networks by running:

$ rm -rf blocks users

Or you can delete the database for a particular network by removing blocks/network_name and users/network_name.
