Overview of the Web3 Data Ecosystem: A Comprehensive Analysis from the Ground Up to Applications

On January 3, 2009, the birth of the Bitcoin genesis block marked the beginning of the Web3 data era. Unlike the Web2 world where data is monopolized by giant companies, in the Web3 world, data is stored on the blockchain with features of tamper-proofing, traceability, and public transparency, returning data sovereignty to individuals and allowing anyone to freely access and analyze this data.

The data ecosystem of Web3 can be divided into three layers: node services, data indexing services, and data applications.

Node Service

Nodes in a blockchain network are primarily divided into two types: full nodes and light nodes. To address the technical and hardware threshold issues, many blockchain node service providers have emerged. They deploy and maintain blockchain nodes, providing services such as RPC interface access, data access, and staking services for certain PoS chains.

Currently, well-known node service providers in the market include:

• ZAN: A Web3 technology brand under Ant Group, providing stable and fast connections for multiple popular blockchain networks.
• Infura: Ethereum infrastructure service provider, offering node management and API management services.
• Alchemy: Committed to becoming the AWS of the Web3 world, providing blockchain development platform services for developers.
• QuickNode: Build a Web3 cloud platform that provides efficient and reliable blockchain services.
• Pocket Network: A decentralized API infrastructure that provides blockchain access services through a trustless API layer.

Data Indexing Service

The data indexing service is mainly aimed at DApp developers, providing faster and more advanced data query interfaces. Some official high-performance public chains offer ready-made open-source indexing service software, and there are also decentralized data indexing service providers like TheGraph.

TheGraph is a decentralized blockchain data indexing and querying network that organizes complex blockchain information into a retrievable format through custom subgraphs, helping developers create fully decentralized applications.

In addition, blockchain domain services such as ENS (Ethereum Name Service) can also be classified as decentralized data indexing services. ENS resolves human-readable domain names into computer-recognizable identifiers and supports "reverse resolution" functionality.

Data Applications

Data applications are mainly aimed at ordinary users, providing tools or products for blockchain data browsing, data analysis, and market analysis.

1. Blockchain explorers: such as Etherscan (Ethereum), Solscan (Solana), and OKLink (multi-chain).

2. Data Analysis Tools:
   • Dune Analytics: A web-based blockchain analytics platform
   • Footprint Analytics: Integrated Analytics Platform
   • DefiLlama: DeFi information aggregator
   • NFTScan: NFT analysis platform
   • Chainalysis: Enterprise data solutions company

3. Market Analysis Tools:
   • CoinGecko and CoinMarketCap: Token Analysis Tools
   • Glassnode and Messari: Blockchain data and information providers
   • DeBank: DeFi Portfolio Tracker
   • 0xScope, Nansen, and Arkham: Professional On-chain Analysis Platforms
   • Dexscreener and Dextools: Decentralized Exchange Data Sites
   • GMGN: A tool website that integrates the line viewing website and the on-chain asset dashboard functionality.

Web3 data has become a core asset, reflecting market dynamics, user behavior, and the overall health of the blockchain ecosystem. The Web3 data ecosystem is continually evolving, providing users with a comprehensive range of services from infrastructure to advanced analytical tools. With technological advancements and growing user demands, there remains tremendous development potential and a broad outlook in the Web3 data field.
