How to Build a Blockchain Application in 7 Steps?

Here are the primary eight steps for developing blockchain applications…..

Analyze the Industry Choose the right blockchain platform Do Competitor Research Design Your Blockchain App Development and Testing Process Deployment Maintenance and Support

Step 1: Analyze and Identify the Industry

Numerous industries require blockchain technology such as gaming, banking & finance, insurance, healthcare, real estate, and security, etc… Let us delve into each sector and understand it for blockchain app development.


The gaming industry has evolved from a game to a professional sport. There are some gaming competitions these days that have a blank market and high financial expenses. Blockchain technology possesses the capability to tackle legacy-related issues within the gaming industry. Sky Mavis, Playkeu, Dapperlabs, The Sandbox, and Uplandme Inc. are some of the blockchain gaming companies. 

Real Estate

In the real estate industry purchasing, and selling often carries the danger of excessive paperwork, fraud, and mistakes in the public record. With the help of blockchain technology, the real estate business can easily eliminate the requirement for paper-based records. Further, the blockchain helps in recording, tracking, and transferring land titles along with ensuring accuracy and credibility. Propy and Chromaway are the industries in real estate that have implemented blockchain. 


The most difficult method in the healthcare business is the usage of several systems to handle and store data. Such kinds of systems include sensitive data, including personally identifiable information, which is highly vulnerable to attack.

Therefore creating a single system for sharing data among the entire institution is highly dangerous. The healthcare sector can share the data with other networks easily. This technology shares the data with integrity and high security. HealthVerity and Hashed Health are the industries that implemented blockchain. 

Banking and Finance

Considering transparency, efficiency, and ease of use the financial sector requires the help of blockchain applications. Payments, Clearness, and Settlement Systems, etc… all the primary services in the banks can be easily sorted out with this technology. JP Morgan Chase, Credit Suisse, and Western Union are already making the most out of blockchain applications. 

Supply Chain

Blockchain technology is now being used in the supply chain business. This means that when different companies work together in the supply chain, it helps to track and show all the steps involved, making everything very clear. For your understanding imagine a restaurant that wants to know where its meat comes from. With blockchain, they can easily trace the history of the meat they use in their dishes. This isn’t just for restaurants but also for other industries like farming, transportation, and fashion can also use blockchain to keep track of their products. Some companies in the supply chain industry that use blockchain are Provenance, Fluent, and Blockverify. They use this technology to ensure transparency and trace the origin of products.

Step 2: Choose the right blockchain platform

Create a blockchain application by choosing the right type of blockchain for your business.  Considering the consensus process and the challenges you desire to address, blockchain apps have 4 different types. They are

Permissionless blockchain (public) – This blockchain is used by all the members of the network and on any device. Anybody can be a part of the blockchain and can make the transactions, can verify, and still stay anonymous. For instance -Bitcoin is a public blockchain.

Permissioned blockchain (Private) – This blockchain is accessed by authorized users alone. Further, this type of blockchain has a set of rules that regulate the transactions between network participants. Private blockchains are mostly preferred by organizations for internal purposes.

Hybrid blockchain – Some organizations prefer choosing the best from both the blockchains. By using this way, we can control access to the specific data stored inside the blockchain and which set of data is open to all the network participants. 

Consortium blockchain – Consortium blockchain is also called federated blockchain. It’s more or less similar to the previous blockchain offering limited access to a specific set of groups. This blockchain can initiate, receive, and validate transactions via the validator node.

After deciding on the type of blockchain platform, you need to analyze the suitable platform for app development. There are 2 ways of developing a Blockchain Platform. They are : 

Craft New Blockchain 

This choice empowers you to establish a new blockchain framework where every aspect, from algorithm design to transaction, is under your control. Despite its high cost, it is considered one of the most unique approaches to blockchain development.

Replicate the Framework of  Leading Blockchain Platforms

Another effective way of creating a blockchain-based application is replicating a well-known blockchain. But these platforms are open source, only you can deploy the code on your servers by simply forking their repository. How effective a blockchain platform is will be determined by the number of network nodes that can validate transactions. Hence the platforms Ethereum, Hyperledger, R3 Corda, and Ripple are just a handful.

Step 3: Do Competitor Research

After planning, do competitor research and find what they are up to.  By doing competitor research, you can get an idea about the common features and functionalities. Find out the strengths and weaknesses of your competitor. Social media like LinkedIn or Facebook can help to identify your competitors. This is an important step in developing a blockchain application. 

Step 4: Design Your Blockchain App

Design your blockchain application, it might be a theoretical build-up or a design prototype. Every project under theoretical build-up needs theoretical incidents in order for customers to understand the product’s applicability and viability. It is possible to write suggestions that outline every aspect of the project. Following the development of a theoretical build-up and feedback, a prototype is created that consists of:

Drawings  Mock-ups Tested information architecture, and  Product designs

Design APIs that are to be incorporated with UI to run an application in the back-end. Visual layouts and designs are created to give a great look and user-friendly feel to the application. 

Step 5: Development and Testing Process

In this phase, you should either have to develop or integrate APIs for specific use cases of the application. The Blockchain application is built under multiple versions. The development and Testing Process is a significant one.

Pre-Alpha – Firstly, A blockchain application development which is not yet undergone formal testing is called a pre-alpha version of the app. Once it got approved by the client, the next stage would be the alpha version. Here the Blockchain app developers will test the software with white-box techniques. 

Beta version – Once the alpha version is released, the Blockchain app will be prepared for the Beta version. In this version, it incorporates the complete features set up but with some unknown bugs. Developers will share the beta version with a certain group of people outside the organization to test its functionality.

Candidate Version – Once the best version is approved and tested, the Blockchain application is released for the candidate version. An advanced beta version will be the final application and it will be launched. 

Step 6: Deployment

After undergoing several tests, the application will finally move to the production phase and get ready for deployment. Before any application goes live, it should be deployed on the test network to test its functionalities promptly. 

The admin manages which version of the apps will be deployed. Once the application is provisioned, it should be hosted on the main chain. If the developed blockchain is a hybrid platform, i.e. it contains both off-chain and on-chain business entities, then it needs to be deployed on the cloud server and in the app store/play store. It should also be able to upgrade according to the needs and prioritization.

Step 7: Maintenance and Support

This phase is meant for updating OS, frameworks, libraries, and adding new features and modifying the application to meet your current business requirements. It also involves addressing any technical issues and implementing the needed updates. This is an essential step to maintain the working of blockchain applications. Maintenance and support are very important to achieve the long-term success and sustainability of the blockchain.

Nearly, gigabytes and terabytes of storage capacity are needed to put up a blockchain. Since you’ve got the knowledge regarding how to build a blockchain application right??
