Distributed cryptographic certification and revocation of academic records.

• Download the latest nightly (not stable) Rust compiler. The latest compiler known to compile CertChain successfully is rustc 1.6.0-nightly (7499558dd 2015-11-28).
• $ ./install.sh to build the secp256k1 shared libraries required by CertChain at compilation and runtime.
• $ cargo build to build CertChain.

• To build CertChain, simply run $ cargo build.
• To run a node, run $ cargo run -- -c <node_conf>, where <node_conf> is a *.conf file in the /conf subdirectory of this repository.
  • Typically, you'll want to run two or more instances of CertChain simultaneously. The files nodeA.conf and nodeB.conf can be used for a two node network. For a four node network, use stanford.conf, virginia.conf, ireland.conf, and tokyo.conf. (Note: the four node network is configured for EC2 and is not yet ready for local development again).
    • Important: Do not forget to add entries to your /etc/hosts file for any non-routeable hostnames used in the *.conf files. For nodeA.conf, add 127.0.0.1 virginia, for nodeB.conf, add 127.0.0.1 stanford.
• As of this writing, the network and daemon modules in the /src subdirectory are changing often. The rest are utility modules that are more stable, and will be changed as additional supporting functions are needed.

• CertChain uses SJCL for client-side block verification. Use the following build string to build SJCL with the dependencies required by CertChain: $ ./configure --without-all --with-sha256 --with-ripemd160 --with-codecHex

• If this is the first time you are running the demo, run $ ./init\_local\_nodes.sh to configure the two local nodes. You only need to go through this process once.
• To run a demo, you might wany to run a local two-node network. To do this, you can simply run $ ./start\_local\_nodes.sh, which will start two nodes in the background with stanford on RPC port 5001, and virginia on RPC port 4001.
• The frontend uses Django. You will need a superuser to log in to the administration system. To do this, run $ ./admin/manage.py createsuperuser --settings=admin.settings.stanford, and follow the instructions.
• Then, start the Django server by running $ ./admin/manage.py runserver --settings=admin.settings.stanford.
• Now you should be able to visit http://127.0.0.1:8000/, log in with the account you just created. Everything is there!
• After you are done, shutdown the server and run $ ./killall.sh to terminate the two nodes.
• To reset the documents, hashchains, and replicas, run $ ./reset.py.
