helium-arango-etl-lite

Lightweight ETL to store adjacency data (e.g. payments, witness receipts) from the Helium blockchain in an ArangoDB database.

Quickstart (Ubuntu)

• Follow these instructions to run blockchain-node.
• Launch ArangoDB via docker

docker run -d --name arango -p 8529:8529 -h 0.0.0.0 -e ARANGO_ROOT_PASSWORD=password arangodb/arangodb:3.8.2

• If you open port 8529, you should be able to view the Arango WebUI in your browser at:

http://{HOST_ADDRESS}:8529

• Clone this repository and cd into the main directory
• Make a copy of .env.template, call it .env, and edit the environment variables with your settings.
• Install dependencies with

pip3 install requirements.txt

• Run the ETL

cd helium_arango_etl_lite && python3 etl.py

After backfilling all blocks stored on the node, the service should listen for new blocks and process them as they come in.
