XRPL UNL Manager

Set of scripts to encode/decode and manage Unique Node Lists for XRPL testnet validators.

Update 14/07/2021 :

• Not released yet, but most of the parts are working.
• Extensive testing is required.
• Documentation and release as python package are in my plans too.

How it works

These scripts are used to execute a scenario of UNL changes in a XRPL Testnet.

• unl_manager.py : can run as a system daemon or standalone. It runs in a loop an executes the UNL changes for each validator as it is defined in the scenario file. When another unl_manager.py process is running in the same publish_path, it can print the status or stop the running process. It also maintains a directory tree in the publish_path that can be served by any Web server.
• decodeUNL.py : decodes,validates and prints a UNL file or a UNL as it has been retrieved by a URL
• encodeUNL.py : encodes and signs a UNL file for the given list of validators
• getTrustGraph.py : parses the scenario file and extracts the connections graph in mermaid or dot format, that can be then used to visualize the graph.

At last, we include a docker-compose file that launches a nginx web server container and a python container running the unl_manager.py daemon.

Requirements

• Python 3
• cryptography 3.3.2
• ECpy
• base64
• base58 >=2.1.0
• Docker

pip install -r ./requirements.txt

Running scripts in a Docker container

The following command launches a Docker container with an interractive shell, after it installing the python modules using requirements.txt file.

SRC_PATH=$(realpath relative/path/to/srcdir) ./docker/launch_container.sh

In case Docker daemon won't find the python:3 image locally, it will pull it from Dockerhub.

The initialization script that runs before the interractive shell can be found in ./docker/init_container.sh.
