 Developers building blockchain-powered applications often encounter challenges related to the retrieval and reading of data stored on the blockchain, leaving data mostly under-utilized. The data retrieval process is inherently complex, computationally expensive, and hampers efficient querying, particularly in terms of speed, reliability, scalability, customizability, and for some protocols, multi-chain data aggregation.
 
+These difficulties pose significant obstacles for blockchain developers, diverting their attention towards infrastructure and maintenance tasks instead of focusing on the core objective of building brilliant dApps. Moreover, optimal performance and reliability are essential for providing users with a frictionless experience when interacting with their favourite dApp.

 Whether it's GameFi, where real-time game state updates are crucial as players submit their moves; NFTs, which require immediate drop status updates; DeFi, which demands real-time price and liquidity information; or Web3 Social, which strives to create a smooth user experience with instant updates, the need for efficient data querying directly impacts user satisfaction and overall UX.

 ## What is a blockchain indexer?
 
+A blockchain indexer is a tool that pulls raw data from a node, organises it into structured tables, and gives developers a clear and fast way to view and work with on chain activity. Similar to the index of a book, it takes complex on chain data and organises it so developers can query, retrieve, and use that data without digging through a full node.

Similar to the index of a book, it takes complex on chain data and organises it so developers can query, retrieve, and use that data without digging through a full node.
 
 Developers only need to define data types and the relationships between them according to the smart contract, and how this data should be stored. The indexing solution then provides a custom GraphQL endpoint to easily present this data for your dApp, while taking care of the rest. By doing so, indexers enable developers to retrieve and process advanced data efficiently, ultimately boosting productivity and allowing more time to focus on the application.
 
+A key advantage of using a powerful blockchain indexing solution like Envio is its ability to abstract the complexity of managing your own infrastructure while keeping costs lower. Indexing solutions are built for low latency and fast access to historic data. With a reliable indexer, you can retrieve filtered data in seconds or minutes, work that would take days or even weeks if you relied only on RPC JSON requests.

 For testing purposes, the developer flow usually allows developers to host an indexer locally, before deploying to a hosted service.

 Blockchain indexing solutions like Envio offer a myriad of benefits, from speeding up the dApp development lifecycle to increasing the responsiveness and reliability of your dApp for a smooth user experience. Here are a few reasons why blockchain indexing solutions play a critical role in the dApp development process:
 
 - Developer friendly: Blockchain indexing solutions make a dApp development easier by abstracting away a lot of the complexities that come with coding data logic and hosting your infrastructure, saving developers a lot of time to focus their efforts on the application. The developer flow of indexing solutions is mostly interactive and automated, with templates and helpful developer quickstart guides to start. In addition, some indexing solutions support familiar development languages such as JavaScript/ TypeScript for data handling, allowing quick onboarding, and testing frameworks for increased confidence.
 
 - **Customizability**: Indexing solutions allow developers to index application-specific data, such as custom events from contract functions. Standard template blockchain data APIs do not support the rich indexing capabilities that indexing solutions can offer. Whether you're launching a multi-chain NFT marketplace, starting a DAO, diving into GameFi, or pioneering the next big P2E project, Indexers serve as an essential building block tailored to your application’s unique data needs.
 
+- **Multichain support**: Some indexing solutions have multi-chain support, which aggregates data from multiple sources into a unified database table, making it super easy to present aggregated information in your front end for your multi-chain blockchain application. Developers do not need to worry about building multiple APIs or subgraphs and managing multiple databases.

 - **Managed service**: Indexing solutions offer free and paid production-grade hosted service options with guaranteed uptimes, ensuring that data access is always available and complete. Depending on the provider, the system architecture of the hosted service ensures performance is always consistent, providing a trustworthy and reliable solution to access real-time or historic blockchain data. Developers can focus on their front-end applications while indexing solutions guarantee performance and production-grade infrastructure.

 > _As a next step I intend to run this data through a price oracle so I can know the USD amounts being liquidated and generate some cool data graphics. […] I’ve made a number of theGraph indexers in the past but this was my first time using Envio. The transition was smooth and intuitive. The most noticeable difference between theGraph and Envio is indexing speed. Anyone who has used theGraph is familiar with the feeling of a cortisol spike when their subgraph abruptly fails after syncing for 26 hours. Since Envio is so ridiculously fast these errors were caught in minutes instead of days. I felt spoiled. I found myself frequently and nonchalantly running `envio dev` to deploy the indexer and check for errors. The iterative developer experience was so much easier thanks to Envio. -_ Joss
