Figure 5. The node starting.
After launching the node, the user can generate the encryption keys by typing ‘g’, or could quit by writing ‘q’. If the option for generating the keys is selected, he might choose a encryption type by selecting the option 1. Afterward, will be presented the options ‘p’ and ‘f’ in order to use the password or a file. Then, the node will try to connect to the Credits blockchain first time. See figure 5.
Figure 6. Connection established with signal server.
Once the password is confirmed, the node will establish connection with the signal server in Credits network.
