Undeniably, blockchain is a tech breakthrough megatrend with unmatchable potential in the future. But investing in blockchain software development can be risky without a clear understanding of how to successfully build and integrate such applications.  

This blog will explore everything you need to know about blockchain app development, from challenges and steps to tech stacks and costs.  

Let’s first start with its roots. 

What exactly are blockchain apps or DApps? 

DApps (decentralized applications) are blockchain apps without servers that act as an intermediary between users that exchange messages, money, or data. It opens lots of possibilities for many industries.  

But, how does a blockchain app work? 

A blockchain app uses distributed ledger technology to store and verify transactions. It ensures transparency, security, and decentralization through consensus algorithms and cryptographic techniques. 

Market Overview of Blockchain Technology 

The blockchain app market has grown significantly. According to Statista, the global DeFi market size was valued at $11.78 bn in 2021 and is expected to expand at a CAGR of 42.5% from 2022 to 2030.  

Market statistics for blockchain technology in 2023 are shown below in the graphic illustration (Resource from finance online). 

 Blockchain Statistics You Must Know

Blockchain technology aims to improve system efficiency, transparency, and trust in addition to its focus on cryptocurrency.  

Benefits of Implementing Blockchain Solutions 

Enhanced Security

Blockchain technology employs advanced cryptocurrency methods to ensure the security of data and transactions. Its decentralization property makes it highly resistant to hacking and manipulation.  

That’s why blockchain is in high in-demand among industries dealing with sensitive data and identity management, such as finance, healthcare, government authorizations, etc.   

Increased Transparency and Trust

Blockchain provides a transparent and unchangeable transaction ledger available to all participants. This transparency boosts trust among users, allowing for real-time auditing without any intermediaries.  

It is especially useful in supply chain management, where stakeholders can trace the origin and movement of goods, ensuring authenticity and ethical practices.  

Streamlined and Efficient Processes

Blockchain has the potential to streamline complex processes and eliminate intermediaries. Both Smart & self-executing contracts with predefined rules coded on the blockchain automate tasks and facilitate the transfer of assets.  

This automation speeds up transactions, and minimizes errors, resulting in improved efficiency and cost savings. 

Improved Data Management and Quality

Blockchain provides secure and decentralized data storage, making it difficult for cybercriminals to hack data and gain unauthorized access. The distributed ledger ensures data is replicated across multiple nodes, enhancing resilience and availability.  

Blockchain's consensus mechanisms also ensure that all participants agree on data validity, improving data integrity and overall quality.  

Facilitates Interoperability and Collaboration

Blockchain has the potential to enable seamless collaboration and interoperability between different organizations and systems. Using standardized protocols and shared ledgers, blockchain can facilitate secure and efficient data exchange, enabling trusted interactions without costly integrations.  

This benefit is particularly relevant in sectors like trade finance, where multiple parties with different systems and processes must work together. 

Blockchain app development challenges 


Blockchain app development challenges Complexity  

Blockchain has complex concepts like distributed ledgers, unity algorithms, and smart contracts. Understanding them is crucial to developing an effective blockchain application, but it is a very challenging task.  

So, hire a blockchain developer who has a solid grasp of these concepts. 


Scalability is a significant challenge in blockchain app development. With the increasing number of blockchain users and transactions, maintaining performance and efficiency is becoming challenging. That’s why, many blockchain apps are losing their active users.

Developing a blockchain app that can handle a growing user base and transaction volume should be a top priority.  


Security is paramount in blockchain applications dealing with sensitive data and financial transactions. Developers must implement robust security measures to protect against smart contract hacking, data breaches, and vulnerabilities. Additionally, ensuring the security of private keys and user wallets is crucial. 

Regulation and Compliance 

Blockchain applications may need to comply with various legal and regulatory frameworks, depending on their jurisdiction. Staying compliant with evolving regulations, such as data protection and anti-money laundering laws, can challenge developers. 

Integration with Existing Systems 

Integrating blockchain applications with legacy systems can be complex, especially if the systems have different data formats or protocols. So, you will need to implement integration solutions to enable seamless communication, and transactions between blockchain and non-blockchain systems.

So, these are a few common challenges many developers or businesses face when building blockchain apps. Make sure you have technical expertise and an idea about user requirements, business objectives, and deep understanding.  

But regardless of your requirements, you’ll need to follow some key steps for developing blockchain apps from scratch. 

Steps to Develop a Blockchain Solution from Scratch 


Steps to Develop a Blockchain Solution from Scratch

Step #1 - Clarify your idea

When building your blockchain app, it’s very important to clarify your idea regarding your product. 

You should identify if you need a blockchain and what you want. Then, consider the issues you want to resolve with your DApp and implement your idea.  

Step #2 - Analyze your Options

Technically, you can develop your DApp in four different ways:   

  • Go with the open blockchain for your app. For instance, you can implement Ethereum or Bitcoin into your mobile app development solution
  • Create a private network with the help of blockchain software. 
  • Integrate BaaS (Blockchain as a Service) provider’s cloud service into your app. Amazon, Azure, and Microsoft all offer BaaS products. 
  • Build your blockchain network as per your preferred platform.

Step #3: Select a Platform

Here are a few platforms you can choose for your blockchain project: 


The most popular platform that allows you to build a blockchain app and create your ecosystem is a language called Solidity. You can also use Ethereum to develop smart contract solutions.   


If you want to exchange data within your own company, Hyperledger is a corporate tool. You will need a team of Go, JS & Java developers to build a blockchain app solution on this platform.

If you want to create a financial tool, Ripple is a great platform. It lets you easily send money anywhere and integrates with banks and payment providers.  

Selecting a platform for your blockchain app will influence your development team’s skill set.   

Step #4 - Design the User Interface

After planning and selecting the right choice regarding the entire blockchain app, you can begin designing the UI for every software element. Visual design affects the app’s overall look, and tech designs impact its architecture.   

Step #5 - Build Your APIs

While many platforms consist of readymade APIs, you may need to develop application programming interfaces, depending on your needs. Here are a few reasons; 

  • Generation of key pairs and addresses 
  • Performance of audit-related functions 
  • Data authentication  
  • Data storage and retrieval 
  • Smart-asset lifecycle management 
  • Smart contracts 

Step #6 - Develop an App

Consider your application's features, workflow, potential for user involvement, and internal services. Create a product by coordinating all of your ideas with the development team. 

Step #7 - Test the App

You can verify the application's accuracy in all respects and prevent mistakes from occurring during future operations with effective testing and QA services.   

Step #9 - Release the App and Get Feedback

Launch the program and get the first users' feedback. Think of ways to make your blockchain app better.
