The Graph, The New Builder Of Metis Andromeda
The Graph is a new builder and a critical piece of infrastructure for the Metis ecosystem, and Metis is thrilled to have them on board.
Oracles, which are a kind of infrastructure that enables off-chain data to be brought on-chain, are something you may be aware with. In this instance, they are dealing with the polar opposite of what they are used to: a reverse oracle.
With the use of reverse oracles, on-chain data may be transported “outside of the blockchain” and made available to Web2 platforms and businesses.
In order to provide some instances of how this may operate, consider any website that displays cryptocurrency tickers along with their individual prices listed on them. These are the pricing of assets that are now on the blockchain. Companies using Web2 technology will be able to access this sort of data without the need of data indexers in certain situations, but the data will be bulky and jumbled. Because of this, the graph makes it easy to understand and use this information, which is not just accessible but also useful.
Subgraphs are available in the Graph, allowing users to do particular data searches. What’s great about this is that once it’s constructed, anybody can access and use the same efficient and focused subgraph that you did. This not only improves the end-user experience, but it also fosters adoption on a broad scale by providing access to on-chain data to all sorts of apps that would not otherwise be able to have access to it.

What kind of information will they be able to have access to?
They have access to any and all blockchain data they choose. Companies can obtain not just the most important cryptocurrency values. These subgraphs enable all projects to access and filter whatever blockchain data they choose on a project-by-project basis using the same infrastructure.
Node in a Decentralized Graph
Participating in a new wave of decentralized graph nodes is in keeping with the decentralization DNA, as they seek to become 100 percent decentralized in the operations and infrastructure. Metis Andromeda is becoming into one of the world’s first permissionless, self-service chains as a result of the recent merger. This, among many other factors, is one of the reasons why they are so enthusiastic about the new integration being introduced. They have now set up a graph-node that refers to the own JSON-RPC endpoints, allowing DApps to deploy subgraphs to the graph-node as a result of this setup. Here’s a really useful guide for any dApps looking to get on board with the wave: Guide
Indexing blockchain data is not easy
Projects need a method of finding the data that they want without having to deal with the complexity of running a complete node to index the data that they require.
The Graph overcomes this problem by using a decentralized protocol that indexes blockchain data and makes it possible to query it in a performant and efficient manner. A regular GraphQL API may then be used to query these APIs (which are called “subgraphs” in the index). Presently, there is a hosted service available, as well as a decentralized protocol with the same functionality. Both are supported by Graph Node, an open source implementation of the graphing language.
