Start demo

To start demo, execute the following commands on separate terminals.

The first ones will start blockchain servers

$ make run_docker_blockchainserver1

$ make run_docker_blockchainserver2

$ make run_docker_blockchainserver3

Note down the ips of the blockchain servers

After that start 2 walletservers, and connect each one to different blockchain server

$ make run_docker_walletserver1

Enter the blockchain server gateway: 
http://172.17.0.3:5000

$ make run_docker_walletserver2

Enter the blockchain server gateway: 
http://172.17.0.4:5000
