Leading Web3 APIs?


Blockchain data pipelines are the backbone of the Web3 industry, playing an essential role in the development of decentralized applications (dapps). Yet, setting up Web3 data pipelines from scratch can be a tricky and time-consuming endeavor, involving many redundant tasks. As such, there has to be a better way, right? 

Fortunately, you can avoid the complexities of setting up the underlying infrastructure required to run and maintain Web3 pipelines with a data provider like Moralis. But what exactly is Moralis? And how can you use our premier tools to build blockchain data pipelines? To find the answers to these questions, join us in this guide. Let’s dive straight in! 

What are Web3 Data Pipelines?

Put simply, Web3 data pipelines – also commonly referred to as blockchain data pipelines – are pieces of infrastructure designed to collect, ingest, transform, and deliver data from networks like Ethereum to dapps and databases. 

Blockchain data pipelines are crucial for businesses and organizations that depend on a continuous and efficient flow of real-time information, making them fundamental in developing a wide range of dapps. This includes everything from crypto wallets to decentralized exchanges (DEXs), underscoring the importance of pipelines in the growing Web3 industry.

How Do Web3 Data Pipelines Work? 

Similar to how water pipelines carry water from a reservoir to your home’s faucets, a Web3 data pipeline transports data from a collection point to a database. Essentially, a Web3 data pipeline retrieves information from a blockchain, indexes and modifies it, and then stores it in a designated location.

The above process can be divided into three core steps: 

  1. Data Collection & Ingestion: Data is collected from various sources – either off- or on-chain – and then gets ingested into the pipeline.
  2. Data Processing: During this stage, the data undergoes processing, which may include formatting, filtering, and applying transformations. These operations prepare it for effective storage and insightful analysis.
  3. Storage & Analysis: Finally, the processed data is stored in a location suited to the requirements of the Web3 project, which could range from traditional databases to cloud storage solutions. The choice of storage often depends on the need for security, scalability, and data accessibility.

That’s an overview of how Web3 data pipelines work. In reality, these steps may be somewhat more complicated and can vary depending on your organization’s needs!

Exploring the Benefits of Blockchain Data Pipelines 

Data pipelines are crucial for the blockchain industry, offering numerous advantages for Web3 developers and end users alike. Below are four key benefits:

  • Real-Time Insights: Web3 data pipelines deliver real-time information, empowering dapp users to derive insights quickly and make informed decisions on the fly. 
  • Efficiency: By automating the flow of Web3 data, blockchain data pipelines decrease the need for manual intervention and significantly reduce the likelihood of errors.
  • Cost-Effectiveness: Automating and optimizing data processing reduces manual labor, improves resource utilization, and decreases error rates, leading to significant cost savings.
  • Data Quality: Data pipelines ensure high standards of data quality through meticulous cleansing and formatting steps, ensuring the accuracy and reliability of the data provided.

The Challenge of Building Web3 Data Pipelines 

While blockchain data pipelines are essential for Web3 development setting them up can be quite a challenge. Building the required infrastructure to query, process, and analyze blockchain data is both a tedious and expensive endeavor! 

Creating Web3 data pipelines from scratch involves several intricate steps. These include establishing a high-performance backfill system, implementing reliable data ingestion mechanisms, and incorporating measures to deal with blockchain reorgs. In addition, you continuously need to check for data completeness. These tasks are time-consuming and divert resources from more strategic activities, such as enhancing product features and crafting engaging user experiences for your dapps.

Fortunately, it’s now possible to circumvent the associated challenges using a Web3 infrastructure provider like Moralis. But what exactly is Moralis? And how can you utilize our industry-leading services to build Web3 data pipelines efficiently?
