Collector Node

A simplified collector node concept from Orcfax. Original documentation available to maintainers can be found: here.

An Orcfax collector node now:

  • Uses cron to request price-feed data every 1x minute.
  • Via this Python script requests the price-feed data via Orcfax's enhanced version of Chronicle Labs gofer.
  • Parses the results from gofer and send the results to a validator web-socket.

Node install

A small recipe for installation on a collector node machine.

NB. the following assumes we're in the home folder root, i.e. ~/. and a username of orcfax, i.e. /home/orcfax/.

Create a collector directory

mkdir -p collector &&cd collector

Download this script

wget https://raw.githubusercontent.com/orcfax/collector-node/main/collector.py -O collector.py
wget https://raw.githubusercontent.com/orcfax/collector-node/main/requirements/requirements.txt -O requirements.txt

Create a virtual environment

python3 -m venv venv
source venv/bin/activate
python -m pip install requirements.txt

Download and initialize node-id

wget https://github.com/orcfax/node-id/releases/download/0.0.1/node-id_0.0.1_Linux_x86_64 -O node-id
chmod +x node-id
./node-id -w ""

NB. the -w argument is legacy and replaced with the use of validator.env in this repository.

Download gofer

wget https://github.com/orcfax/oracle-suite/releases/download/0.0.1/gofer_0.0.1_Linux_x86_64 -O gofer
chmod +x gofer

Edit crontab

Open crontab

crontab -e

Amend the file with the following

# Required.ORCFAX_VALIDATOR=
NODE_IDENTITY_LOC=
NODE_SIGNING_KEY=
CNT_DB_NAME=
OGMIOS_URL=
# Optional.OGMIOS_VERSION=v6
* * * * * /home/orcfax/collector/venv/bin/python /home/orcfax/collector/collector.py 2>&1 | logger -t orcfax_collector

NB. crontab will read the environment variable from its own context when it is set there.

Congratulations

The collector node should be installed. You can view log output in the syslog.

sudo tail -f /var/log/syslog | grep orcfax_collector

Developer install

pip

Setup a virtual environment venv and install the local development requirements as follows:

python3 -m venv venv
source venv/bin/activate
python -m pip install -r requirements/local.txt

Upgrade dependencies

A make recipe is included, simply call make upgrade. Alternatively run pip-upgrader once the local requirements have been installed and follow the prompts. requirements.txt and local.txt can be updated as desired.

tox

Run tests (all)

python -m tox

Run tests-only

python -m tox -e py3

Run linting-only

python -m tox -e linting

pre-commit

Pre-commit can be used to provide more feedback before committing code. This reduces reduces the number of commits you might want to make when working on code, it's also an alternative to running tox manually.

To set up pre-commit, providing pip install has been run above:

  • pre-commit install

This repository contains a default number of pre-commit hooks, but there may be others suited to different projects. A list of other pre-commit hooks can be found here.

Packaging

The Makefile contains helper functions for packaging and release.

Makefile functions can be reviewed by calling make from the root of this repository:

pre-commit-checks Run pre-commit-checks.

Congratulations
The collector node should be installed. You can view log output in the syslog.
sudo tail -f /var/log/syslog | grep orcfax_collector
Developer install
pip
Setup a virtual environment venv and install the local development
requirements as follows:
python3 -m venv venv
source venv/bin/activate
python -m pip install -r requirements/local.txt
Upgrade dependencies
A make recipe is included, simply call make upgrade. Alternatively run
pip-upgrader once the local requirements have been installed and follow the
prompts. requirements.txt and local.txt can be updated as desired.
tox
Run tests (all)
python -m tox
Run tests-only
python -m tox -e py3
Run linting-only
python -m tox -e linting
pre-commit
Pre-commit can be used to provide more feedback before committing code. This
reduces reduces the number of commits you might want to make when working on
code, it's also an alternative to running tox manually.
To set up pre-commit, providing pip install has been run above:
  • pre-commit install
This repository contains a default number of pre-commit hooks, but there may
be others suited to different projects. A list of other pre-commit hooks can be
found here.
Packaging
The Makefile contains helper functions for packaging and release.
Makefile functions can be reviewed by calling make from the root of this
repository:
help Print this help message
pre-commit-checks Run pre-commit-checks.

Collector Node
A simplified collector node concept from Orcfax. Original documentation
available to maintainers can be found: here.
An Orcfax collector node now:
  • Uses cron to request price-feed data every 1x minute.
  • Via this Python script requests the price-feed data via Orcfax's enhanced
version of Chronicle Labs gofer.
  • Parses the results from gofer and send the results to a validator
web-socket.
Node install
A small recipe for installation on a collector node machine.
NB. the following assumes we're in the home folder root, i.e. ~/. and a
username of orcfax, i.e. /home/orcfax/.
Create a collector directory
mkdir -p collector &&cd collector
Download this script
wget https://raw.githubusercontent.com/orcfax/collector-node/main/collector.py -O collector.py
wget https://raw.githubusercontent.com/orcfax/collector-node/main/requirements/requirements.txt -O requirements.txt
Create a virtual environment
python3 -m venv venv
source venv/bin/activate
python -m pip install requirements.txt
Download and initialize node-id
wget https://github.com/orcfax/node-id/releases/download/0.0.1/node-id_0.0.1_Linux_x86_64 -O node-id
chmod +x node-id
./node-id -w ""
NB. the -w argument is legacy and replaced with the use of validator.env in
this repository.
Download gofer
wget https://github.com/orcfax/oracle-suite/releases/download/0.0.1/gofer_0.0.1_Linux_x86_64 -O gofer
chmod +x gofer
Edit crontab
Open crontab
crontab -e
Amend the file with the following
# Required.ORCFAX_VALIDATOR=
NODE_IDENTITY_LOC=
NODE_SIGNING_KEY=
CNT_DB_NAME=
OGMIOS_URL=
# Optional.OGMIOS_VERSION=v6
