How to install Sentinel for Scope

Sentinel is an autonomous agent for persisting, processing and automating Scope governance objects and tasks. It is a Python application which runs alongside the Scope wallet instance on each Scope Masternode.

These instructions cover installing Sentinel on Ubuntu 16.04 / 18.04.


Make sure Python version 2.7.x is installed:

python --version

Update system packages and ensure virtualenv is installed:

$ sudo apt-get update $ sudo apt-get -y install python-virtualenv

Install Sentinel

Clone the Sentinel repo and install Python dependencies.

$ git clone && cd sentinel $ virtualenv ./venv $ ./venv/bin/pip install -r requirements.txt


Sentinel is “used” as a script called from cron every minute.

Set up Cron

Set up a crontab entry to call Sentinel every minute:

$ crontab -e

In the crontab editor, add the lines below, replacing ‘/path/to/sentinel’ to the path where you cloned sentinel to:

* * * * * cd /path/to/sentinel && ./venv/bin/python bin/ >/dev/null 2>&1

Test Configuration

Test the config by running tests:

$ ./venv/bin/py.test ./test

With all tests passing and crontab setup, Sentinel will stay in sync with scoped and the installation is complete


An alternative (non-default) path to the scope.conf file can be specified in sentinel.conf:



To view debug output, set the SENTINEL_DEBUG environment variable to anything non-zero, then run the script manually:

$ SENTINEL_DEBUG=1 ./venv/bin/python bin/
