Introducing Subgraph Radio: Accelerating Network Information Exchange


The GraphOps team, a core dev team at The Graph, proudly introduces Subgraph Radio - an innovative tool within The Graph Network aimed at boosting data and information exchange between Indexers and subgraph developers.

This tool is set to dramatically improve collaboration and efficiency by providing:

  • Proof of Indexing (POI) Cross-Checking: A robust mechanism for Indexers to ensure data integrity, detect discrepancies rapidly, and mitigate potential conflicts within the network.
  • Subgraph Upgrade Pre-sync Feature: A forward-thinking feature allowing developers to announce subgraph upgrades, enabling Indexers to synchronize new versions ahead of time, reducing friction and enhancing network responsiveness.
  • Integrated Notifications & Monitoring: Compatibility with platforms like Slack, Discord, and Telegram for real-time alerts, coupled with comprehensive monitoring through detailed logs and metrics accessible via Prometheus and visualizable through Grafana dashboards.

Easy setup, detailed documentation, and various deployment options ensure that both novice and experienced users can harness the full potential of Subgraph Radio to enhance their operations within The Graph Network.

The GraphOps team is thrilled to announce the release of Subgraph Radio, a transformative tool designed to streamline data and information exchange amongst Indexers and subgraph developers, enhancing the productivity, efficiency, and cost-effectiveness of The Graph Network.

This release marks a significant contribution as part of the New Era roadmap, which among other enhancements, promises more support for Indexers and subgraph developers in the form of helpful tools. Subgraph Radio aims to become the standard communication tool among Indexers and Subgraph Developers, significantly enhancing collaboration and efficiency across the network.

Indexers and subgraph developers should get started now and unlock its full potential - get started here.

Introducing Subgraph Radio

Subgraph Radio is the newest Indexer Component redefining the dynamics of information exchange on the network. Leveraging the Graphcast Network, Subgraph Radio enables seamless data exchanges pertaining to subgraphs, marking an innovative advancement in network communications.

Proof Of Indexing (POI) Cross-checking

Alongside other Proof of Indexing (POI) tools like Graphix, Subgraph Radio offers a meticulous cross-verification of Proof of Indexing (POI) hashes among Indexers. This feature positions Subgraph Radio as a robust early warning system for discrepancies, safeguarding data integrity, fostering trust, and minimizing conflict within the network. For example, Subgraph Radio enables Indexers to immediately detect errors, with minimal cost, and take instant action - such as resyncing the subgraph, bisecting for source of error, closing allocations, and more. This helps indexers avoid slashing in query disputes due to serving bad data.

Upgrade Pre-sync Feature

Developers can now leverage the new Subgraph Upgrade Pre-sync feature to announce imminent upgrades to new subgraph versions, granting Indexers an opportunity to sync them in advance.

Subgraph developers can send a message before publishing a new subgraph version on-chain to reduce the upgrade friction and allow proactive engagement with new deployments. At the same time, Indexers running the Subgraph Radio that have enabled the Subgraph Upgrade pre-sync feature will receive the message and start syncing the new deployment.

Subgraph developers can also use the Graphcast CLI, tailored for discontinuous participation on the Graphcast P2P network, to message all Indexers engaged with a particular subgraph.

Subgraph Radio Notifications & Monitoring

Users can integrate Subgraph Radio with popular platforms like Slack, Discord, and Telegram to receive instant alerts on POI discrepancies. Comprehensive system monitoring is facilitated through detailed logs, ensuring optimal performance and reliability.

Additionally, Subgraph Radio provides extensive metrics which are accessible via Prometheus and visualizable through Grafana dashboards. Set-up is made easy with local servers and specified environment variables for a customized overview of operations.

What’s New in Subgraph Radio 1.0.0

This release of Subgraph Radio 1.0.0 includes a number of features that will supercharge communication and efficiency on The Graph Network including:.

  • Database Persistence: This improvement focuses on ensuring data longevity and scalability, making data storage more efficient and reliable.
  • Validate Configurations: Subgraph Radio now includes more rigorous validation methods for configurations, using stricter checks for the Indexer address variable to validate Indexer configurations.
  • Radios Switched to Using Relay Nodes: To scale Graphcast Network, new mechanisms were enabled on all radio nodes, including Waku’s Relay Protocol and Discovery V5. Radios will be able to directly publish and circulate messages throughout the network and discover new peers through a distributed hash table.
  • Improved End-To-End Tests: New end-to-end tests have been added to Subgraph Radio to test that persisted state and API responses match. Other message types testing has also been added to decode different types of messages.

Privacy & Scalability

Subgraph Radio uses Waku’s advanced features to facilitate efficient and secure communications among Indexers. As a robust suite of communication protocols built on top of libp2p networking stack, Waku emphasizes privacy and resilience against censorship for web3 applications.

Waku employs bi-directional binary gossip streams to safeguard privacy and supports decentralized communication, effectively countering censorship. Moreover, Waku's protocols are adaptable, transport agnostic, and scalable, ensuring reliable performance even in environments with limited resources, such as browsers and mobile devices.
