1. mkdir workspace
2. cd workspace
3. python -m venv env
4. python -m venv env
5. Setup pyring:
   • git clone --recurse-submodules https://github.com/bartvm/pyring.git
   • cd pyring
   • python setup.py build
   • python setup.py develop
6. Setup this repository:
   • git clone ...
   • cd <repo>
   • chmod 777 setup.sh

0. Generate reencryption keys for the blockchain nodes python3 src/keygen.py -f <output-file-name>
1. Run the proxy, python3 proxy-reencryption.py -p <port num>. Right now it is hardcoded to port 5000.
2. Run blockchain nodes python3 src/server.py -p 5001 -n 5001 5002 5003 -f <key-gen-file-name>
3. curl http://localhost:5001/startexp/
4. To invoke the APIs, use:
   • python run.py -f startexp -s 5001 to start
   • python src/run.py -f upload -s 5001 -d <file to share> to upload
   • python src/run.py -f share -s 5001 -r 5002 -t <txn ref of upload> to share
