Oracle Binary


This guide assumes use of Debian-based operating systems. Additional support for other operating systems and architecture will be added.
  • 2 core CPU at a minimum(recommended 4-8 cores).
  • 4 GB of RAM minimum (recommended 8GB).
  • Node.js v14 or higher installed (required to run binary).
  • Configuration json file

Configuration File

Configuration file now consists of four properties:
"nomics": "<nomics API Access Key>", // for crypto data fetch
"finnhub": "<finnhub API Access Key>", // for fiat data fetch
"mnemonic": "<mnemonic of oracle stash account>", // for data submission
"rpc": "<rpc endpoint of the network>" // network to submit
Make configuration file and save the sensitive data in a safe directory.

One-line startup Script

This script performs all the installation and configuration steps as outlined below in the article.
# replace <settings-dir> with your directory of specific settings file directory, e.g. /lumen-settings/settings.json
# settings.json should be like:
# {
# "<data source>": "<Data source Access Key>",
# ...
# "mnemonic": "<mnemonic of oracle stash account>0",
# "rpc": "<rpc endpoint of the network"
# }
npm i -g @digitalnative/lumen | lumen <settings-dir>



We build and maintain binaries using Github. Compiled binaries are available from NPM Versions page.

Building from sources

After cloning from Github, developers can build the binary in local environment. The computer should install:
  • lerna
  • yarn
After installing these software, go to the root directory of the repository then run command
Then, the packages will be bootstrapped. After that, go to core package repo and then execute javascript code with the following command:
node dist/index.js run <directory to lumen config json file>
