"It is our entry-level article on Polkadot from zero to one. We try to start from the most basic part of Polkadot and provide you with a comprehensive understanding of Polkadot.

Today is the 67th issue of this column. Web3 allows users to have ownership and autonomy over their own data, which is also the key to promoting the realization of the Web3 vision. Therefore, huge data has spawned services such as data analysis and data indexing. Mining data value
Data is a very important part of the Web3 world, and in Web2, power and data are in the hands of those tech giants.But the data of Web3 belongs to individuals, and they are usually stored in the blockchain. How to organize and display the data from the blockchain, and provide the function of secondary processing and analysis of the data will be very useful. Contribute to the development of the Web3 industry.。
In addition, the ever-emerging Web3 applications are also accompanied by the growth of users and the complexity of behavior, and the requirements for data analysis and processing capabilities are also increasing. It can be said that there is a huge data mining value in the blockchain network.
No matter how the blockchain develops, the Web3 world will eventually be a form of interconnected chains, and
Polkadot also thinks so: no single blockchain can do everything, more precisely, the future is multi-chain
When data becomes more and more the key to the development of the Internet, more reliable, high-performance, and scalable data services become an indispensable element.
Subsquid
Tools to highlight and aggregate data within blockchains are an integral part of a multi-chain future.
Just like the data aggregation layer, parachains require robust and secure methods for indexing and aggregating data.。
Indexing and querying
SubQuery
Subsquid is an open source framework for building custom GraphQL api interfaces to query state and historical data of Substrate chains.
Subsquid replaces the directly accessed gRPC node with the high-performance Squid archiving gateway, allowing the API to quickly synchronize with historical data on the chain
Web3Go
The Subsquid-driven API supports out-of-the-box testing, can participate in data filtering, data paging, integrated data types, data interfaces, and full-text search, and can be further extended through custom GraphQL parsers.
The Graph
SubQuery is an indexer that allows indexing, transformation, and querying of Substrate chain data to support applications.
Rely on a decentralized network to act as a chain-agnostic data aggregation, indexing, and query layer between blockchains and applications. And SubQuery uses the SubQuery SDK to extract the unique data characteristics of the blockchain.。
Web3GO is an open data analysis platform based on Polkadot. It provides infrastructure and tools to help users realize data visualization, data display, data sharing and analysis of data on the chain.
Covalent
The Graph is a Layer1 indexing tool and query layer for decentralized networks, and it announced the introduction of data indexing and querying into Polkadot.
The Graph is an indexing protocol for querying blockchain data, creating fully decentralized applications
The Graph allows developers to build and publish open APIs called Subgraphs. And developers can use GraphQL to query it.。
Covalent provides a unified API to identify data on the blockchain, and it currently runs on the Moonbeam network, sending billions of data points to the Polkadot-based blockchain through its unified API.
This approach simplifies the development of Polkadot-based blockchain applications compared to implementing full parachains or parathreads.
Polkadot-based block explorerhttps://wiki.polkadot.network/docs/build-tools-index##block-explorers
The Polkadot network is booming and ecological projects are emerging one after another. The Polkadot Ecological Research Institute focuses on Polkadot ecological trends and grasps current trends. Reply to [Daily] to get the latest daily news summary of Polkadot ecology.
It is conceivable that Polkadot-based block explorers also provide data analysis through an interface where users can check public data points.
