Outline/protocol server for Orcfax Custom Feeds.
Demonstrates a sample deployment for a data provider website, e.g. Proof of Reserve; IoT; or any other data provider/collector service.
Public and private keys are created on initialization and the public key made available to the application.
NB. The private key is in memory for the purposes of demo only and would need to be offline elsewhere with other rotation based protections.
Data is made available via API on-demand or as microdata every 30 seconds. In a production system, the method of production would be customized.
Data is then archived in a predictable manner as JSONL. The JSONL looks as follows:
1. {data that can be verified by pkey}
2. {pkey data}
3. {data that can be verified by pkey}
4. {pkey data}
Two lines must be read at a time to verify data. Filtering can be done based on the data time stamp and understood using the public key in the line immediately following it.
Strategies can be created to monitor the integrity of these archival logs or make the data available through different terms.
This is a very simple demo and doesn't have full production qualities. To install and run:
python -m venv venv
source venv/bin/activate
python -m pip install -r requirements/requirements.txt
python main.pyTo view CLI options:
python main.py -hTo install local dependencies and run basic tests:
python -m pip install -r requirements/local.txt
