The Evolution of Blockchain Data Indexing Technology: From Raw Data to Smart Services

1. Introduction

From the earliest blockchain applications to the flourishing variety of decentralized applications in today's multi-chain environment, the accessibility of blockchain data has always been a key factor in the industry's development. With the rise of artificial intelligence technology, data has become increasingly important as the "nourishment" for AI systems. This article will delve into the development history of blockchain data indexing technology and conduct a comparative analysis of several representative data service protocols.

2. The Evolution of Data Indexing

2.1 Data Source: Blockchain Node

Blockchain nodes are the foundation of the entire network, responsible for recording and storing all transaction data. However, for ordinary users, building their own nodes is not only technically challenging but also requires bearing high hardware and bandwidth costs. To address this issue, RPC node providers have emerged, lowering the barrier for users to access on-chain data through standardized API interfaces.

2.2 Data Parsing: From Raw Data to Usable Data

The raw data obtained from blockchain nodes is often encrypted and needs to be parsed to become a comprehensible and operable format. The success of data parsing directly affects the efficiency of blockchain data applications.

2.3 Evolution of Data Indexers

With the explosive growth of blockchain data, the demand for data indexers is becoming increasingly prominent. Indexers simplify the process for developers to obtain the information they need by organizing on-chain data and providing a unified query interface. Different types of indexers each have their advantages, from full node indexers to specialized indexers, and then to aggregated indexers, all playing roles in different scenarios.

2.4 Full Chain Database: Application of Flow Priority Concept

As application demands become more complex, standardized indexing formats struggle to meet diverse query needs. Blockchain data service providers are beginning to develop towards building blockchain data streams to achieve real-time data processing and analysis. This shift further releases the potential for managing and utilizing on-chain data.

3. AI Empowered Data Services: A Comparative Analysis of The Graph, Chainbase, and Space and Time

3.1 The Graph

The Graph provides multi-chain data indexing and query services through a decentralized network of nodes. Its core products include a data query execution market and a data indexing cache market. The network is composed of indexers, curators, delegators, and developers, ensuring the healthy operation of the system through economic incentives. Recently, The Graph ecosystem has introduced several AI-driven tools, such as AutoAgora, Allocation Optimizer, and AgentC, further optimizing system performance and user experience.

3.2 Chainbase

Chainbase is a full-chain data network that integrates multi-chain data and provides real-time data lake services. Its features include a dual-chain architecture based on Eigenlayer AVS, an innovative data format standard "manuscripts", and a crypto world model created by combining AI technology. Chainbase's AI model Theia is based on NVIDIA's DORA model, which can deeply mine the potential value of on-chain data and provide users with intelligent data services.

3.3 Space and Time

Space and Time (SxT) is dedicated to creating a verifiable computing layer, achieving zero-knowledge proofs on decentralized data warehouses through innovative Proof of SQL technology. This approach changes the data verification method under traditional consensus mechanisms, improving system efficiency. SxT also collaborates with Microsoft AI Lab to develop generative AI tools, simplifying the process for users to interact with blockchain data through natural language processing.

Conclusion and Outlook

Blockchain data indexing technology has evolved from the initial node data source, through the development of data parsing and indexing, ultimately advancing to AI-powered full-chain data services, undergoing a continuously improving process. These technological advancements have not only enhanced the efficiency and accuracy of data access but also brought users an intelligent experience.

In the future, with the continuous development of new technologies such as AI and zero-knowledge proofs, blockchain data services will become further intelligent and secure, continuing to play an important role as industry infrastructure and driving innovation and progress across the entire ecosystem.
