Babylon Network Gateway

This system is designed to be the Radix-run publicly exposed gateway into the Babylon Radix network. It is the successor to the Olympia Gateway.

Using the Gateway API

For documentation on the Gateway API, see the Gateway API docs.

Version Support & Network Compatibility

We only support the latest version of Network Gateway and we don't plan to fix bugs in older versions. If you're facing some issues, please upgrade to the latest version of Network Gateway first Releases

Be aware that protocol updates on the network might result in a mandatory Network Gateway update (e.g. anemone protocol update required gateway upgrade to v1.3.0)

Community Involvement

Please see CONTRIBUTING.md

Structure

The system is in three main parts:

  • Database Migrations - This project has ownership of the PostgreSQL database schema migrations.
  • Data Aggregator - Reads from the Core API of one or more full nodes, ingesting from their Transaction Stream API and Mempool Contents API, and committing transactions to a PostgreSQL database. It also handles the pruning (and resubmission where relevant) of submitted transactions.
  • Gateway API - Provides the public API for Wallets and Explorers, and maps construction and submission requests to the Core API of one or more full nodes.

Technical Docs

For docs giving an overview of the Network Gateway and its place in the Radix Ecosystem - including information on the Radix-run Network Gateway, and how to run one of your own - check out the Radix Babylon docs site.

For docs related to development on the Network Gateway, see the docs folder.

For docs related to running a Network Gateway locally, see the instructions about running a local toy deployment in the deployment folder.

Database Migrations & Application Deployment

While all three main system parts are technically independent of each other it is assumed that during overall stack deployment the following order is preserved:

  1. Deploy Database Migrations. This is a short-lived container that executes new database migrations, if any, and exists successfully with 0 exit code. Should this container fail to apply database migrations (non-successful exit code) deployment procedure must be aborted.
  2. Deploy Data Aggregator. Wait until application healthcheck endpoints report Healthy status.
  3. Deploy Gateway API.

Hint: For Kubernetes cluster deployments it is recommended to set up Database Migrations as init container of Data Aggregator.

Note: Babylon Network Gateway is NOT compatible with previous Olympia version. Brand-new, clean database must be used. If you're upgrading from Olympia and deploying for the very first time you may want to run Database Migrations application with WIPE_DATABASE=true configuration parameter to drop existing database and recreate it. This is irreversible operation. Proceed with caution!

Dependencies

Mandatory dependencies:

  • Connection to at least one RadixDLT Node - source of network transactions,
  • PostgreSQL version 15.2 or newer - primary storage.

Optional dependencies:

  • Prometheus - for metrics collection.
