Blockchain apps, also known as dApps, are gaining popularity among businesses. However, there is still a maturity barrier to blockchain adoption. People’s level of trust in the Blockchain varies. The friction can be attributed to a lack of understanding of dApp architecture concepts and their ability to solve complex business problems.

To be truly efficient, a dApp should be designed and curated in the following ways. Many variables are to consider, including API management, architectural capabilities, system integration, transformation and connectivity, security performance, and resilience.

Taking the lead, this insight explains the steps to design a dApp architecture for blockchain applications to help startups and enterprises comprehend dApps as dependable and stable enterprise-grade solutions.

But first, imagine you are trying to build an application for recording aircraft maintenance on the Blockchain. The idea behind the software is that when a user looks for a flight, say from New York to San Francisco today. The app calculates the number of carbon emissions flights will generate by getting hold of the aircraft maintenance history. To help customers choose which flight to take, the app might display red, yellow, and green lights to show the status of each flight’s aircraft maintenance.

Data Gathering

Steps to design a dApp architecture

The application’s first step is to collect all data, beginning with the manufacturer’s data. A smart contract allows aircraft manufacturers to send all data related to their aircraft. The airline company can use aircraft manufacturing data structured within a blockchain. Procurement data will store on the Blockchain in the same way. The airline company can easily create electronic flight logs or any other information logs required for any other system by utilizing procurement and manufacturing data. In the meantime, MRO service providers can use flight logs, manufacturing and procurement data, and smart contracts to generate maintenance data.

As a result, all maintenance and support data types are captured and gathered in the Blockchain at the first layer of dApp architecture development.

Data Processing

Steps to design a dApp architecture

After the data has been captured and structured, the next step is to process it. Now that the data is in the Blockchain, the following architectural requirement is to interface with the app and trust the data so that auditors, customers, or resale agencies can interact with it.

The design and development of dApp interfaces is a multi-faceted process. To design the interfaces of a dApp, many factors and attributes must consider. The following section explains how dApp interfaces are conceptualized and built, what factors to consider, and how to bring everything together. We will continue to refer to the sample dApp- the aircraft maintenance record-keeping application- for clarity.


Data capture on the Blockchain is the first layer of dApp architecture development. To do so, the developers or architecture team must first decide on the best blockchain platform based on the application’s use case.
