we wanted to let you know that, over the next couple of months, Edge & Node will be spinning up what we call an “upgrade Indexer”. This upgrade Indexer will act as a fallback for subgraph queries that cannot be handled by other Indexers in the network. It will support many of the chains that are today only supported on the hosted service.
What does upgrade Indexer mean?
This Indexer will help bootstrap chains on the network and improve the experience of upgrading subgraphs from the hosted service by ensuring that there is an Indexer ready to serve queries right after a subgraph or a new subgraph version is published to the network.
To achieve this, the upgrade Indexer will support many of the chains that are only supported on the hosted service today, and will have many of the hosted service subgraphs already synced.
What does this mean for the Indexer community?
Chains that are currently only supported on the hosted service will soon be available on the network as well. We expect this to lead to more subgraphs to be published on the network, available for Indexers to index and serve in return for query fees.
Our upgrade Indexer will allocate only the minimum amount per subgraph and will not be collecting indexing rewards, only query fees for queries served. This is to avoid being competitive with other Indexers in the network. We expect the upgrade Indexer to be a temporary participant in the network until the respective chains and subgraphs are sufficiently serviced by other Indexers. For chains and subgraphs that are supported by enough Indexers with a high quality of service, the upgrade Indexer is merely a fallback.
We welcome Indexers to join us in supporting the process of upgrading more subgraphs to the network. To make this as easy as possible, we will publicly share a list of relevant chains and subgraphs in advance, to enable the Indexer community to pre-index them as well, and help make switching to the network a smooth experience for everyone.
What does this mean for subgraph developers and data consumers?
Once the upgrade Indexer is live, subgraphs that are upgraded from the hosted service or published from Subgraph Studio can be queried on the network right away, with no lead time being required to index them first.
The upgrade Indexer will also enable chains on the network that are only supported on the hosted service today or that don’t attract enough Indexers due to a lack of indexing rewards.
As we enter the sunrise of decentralized data, the upgrade Indexer isn’t just a safety net, but the bridge that will enable all subgraphs to upgrade to The Graph Network and take us one step further in making The Graph the Internet’s unbreakable foundation of open data.
