Rootstock setup

To get started, we first need to install  RskJ (a Java implementation of the RSK protocol).  The setup process is quite straightforward, and uses the following commands:

sudo add-apt-repository ppa:rsksmart/rskj
sudo apt-get update
sudo apt-get install rskj

Once installation finishes, a configuration wizard will prompt you to select your network. Let's choose testnet:

To reconfigure your node once installed, you need to change the configuration files that are located in /etc/rsk/. Firstly, in node.conf, you have to enable account creation by adding  enabled = true  inside the wallet configuration section:

wallet {
  accounts = []
  enabled = true
}

Secondly, change the CORS parameter from  cors = "localhost"  to  cors = "*".

We also enable the prune service by setting the parameter enabled = true in the prune section.
