8. Software Tarball

In this step you will download and extract the xx network software for the node computer.

About the Tarball​

The xx network software is distributed in a compressed archive know as a tarball. With the exception of the PostgreSQL database, all of the xx network binaries, scripts, libraries, configuration files, and logs are located in the /opt/xxnetwork/ directory of the filesystem.

Download the Node Tarball​

cd /opt && sudo curl -L -O https://docs.xx.network/mainnet/node.tar.gz

Verify the Tarball Checksum​

Verify the tarball

Visit the xx Network Tarball Page

Find the SHA256 checksum of the Node tarball and compare it with the output of the following command.

sha256sum /opt/node.tar.gz

Below is example output and it may differ from the current tarball's checksum.

Please get help, if the output does not match the current tarball's checksum found on the xx Network Tarball Page

Extract the Tarball​

sudo tar -xvf node.tar.gz
