What Is Blockchain App Development: Today and Tomorrow

Blockchain app development is the process of creating applications that use blockchain technology as their underlying platform.

You may be familiar with the concept of blockchain as a decentralized ledger system, right? Then what exactly are blockchain apps? Blockchain apps are decentralized applications (DApps) operating on a peer-to-peer network, free from centralized control. 

Leveraging blockchain technology, these apps ensure secure and transparent data storage and transaction mechanisms.

In the technology and economic balancing trend, the new way of developing apps with blockchain is taking center stage. From finance to healthcare and even supply chain management, this technology is disrupting various sectors with its decentralized and secure nature.

According to the Developer Report, as of October 2022, the global count of active blockchain developers stood at 26,700. However, by October 2023, there had been a 27% decline, reducing the developer count to 19,300.

Don’t be disappointed, though. The reason behind such decline could be attributed to the departure of part-time Bitcoin developers and individuals engaged in various blockchain projects.

With the growing adoption of blockchain technology in businesses, the demand for blockchain app developers is projected to rise in the upcoming years. 

In the emerging AI and IoT era, the significance of blockchain app development will further intensify. Thus, there is a pressing need to embrace this technology and create innovative blockchain applications.

Types of Blockchain Apps

Before you become a developer of blockchain apps, you must know all their types. Broadly, there are five significant types of blockchain apps.

Type 1. Financial Blockchain Apps

Also known as Decentralized Finance or DeFi apps, these apps primarily deal with financial transactions and monetary assets. They are built on blockchain networks and offer lending, borrowing, trading, and more features.

These apps are more secure and transparent. They also remove the need for middlemen, like banks.

There are other types of blockchain apps, too. These include crowdfunding platforms, investment apps, and more. Plus, auction, gaming, gambling, and prediction market platforms also fall under the Financial apps category.

For example, apps like MakerDao and Compound are on the Ethereum blockchain. They offer lending and borrowing.

Type 2. Non-Financial Blockchain Apps

While financial apps deal with monetary transactions, non-financial blockchain apps have a more comprehensive range of use cases. These can include supply chain management, identity verification, data storage and sharing, voting systems, and more.

The major advantage of using blockchain for these types of apps is the immutability of data. Once information is recorded on the blockchain, it cannot be altered or deleted. This makes it ideal for blockchain use cases where security and transparency are paramount.

One example of a non-financial app is Everledger, which uses blockchain to track the supply chain of diamonds.

Type 3. DAOs

Decentralized autonomous organizations (DAOs) are like super ambitious DApps in the crypto scene. They aim to create a company without a boss. They set rules on how members can jump in, vote, or handle company funds during development. In crypto, DAOs run on smart contracts, which is why Ethereum paved the way for their infrastructure.

Although they are still in their early stages, DAOs can offer businesses a new level of decentralization and transparency.

The DAO, a well-known instance of a DAO, is a blockchain-based venture capital fund. It successfully raised over $150 million in Ether in 2016. However, it fell victim to a hack stemming from vulnerabilities in the code base.

Type 4. Asset Management Blockchain Apps

Blockchain-based asset management apps help trade, track, and manage assets like real estate, stocks, and metals. These apps use smart contracts, which ensure safe and clear ownership records.

With traditional asset management systems, there is always a risk of fraud or errors in record keeping. Blockchain eliminates these risks by providing an immutable and decentralized ledger system. This can bring a higher level of trust and security to the asset management industry.

Type 5. Network Administering Blockchain Apps

Network administering blockchain apps means creating and managing networks of blockchain nodes. These applications function as a monitoring system for the blockchain network, ensuring its smooth operation.

They also provide information about transactions and blocks on the network. This helps developers find any issues or bugs.

Let’s discuss the types of blockchain networks. The two most popular ones are public and private networks.

Anyone with internet access can access public blockchain networks like Bitcoin or Ethereum. Private blockchain networks, on the other hand, require permission to access them. It makes them more suitable for businesses looking for a secure yet efficient way of managing their data.

With network administering blockchain apps, businesses can effectively monitor and manage their internal blockchain networks.

10 Expert Tips for Successful Blockchain App Development

Now that you know about the different types of blockchain apps, it’s time to learn 10 expert tips that will help you develop successful ones.

Tip 1. Understand the technology

Blockchain technology may seem complex, but first, you must have a clear understanding of how it works before diving into development. This will help you make informed decisions and avoid potential mistakes that could cost time and resources.

For example, if you look into the types of consensus algorithms, you might learn that Proof-of-Work (PoW) and Proof-of-Stake (PoS) each have pros and cons. Understanding these differences can help you choose the most suitable algorithm for your app.

Tip 2. Define the problem

As a professional developer, more than technical knowledge is required. You have to define a particular problem. This clarity guides the development process and ensures your app has a clear value proposition for its users.

For instance, consider a supply chain management app. The problem might be the lack of transparency and inefficiency in tracking products’ origins and handling. 

Using blockchain, your app could provide an unchangeable ledger. It would ensure that all parties in the supply chain have access to realtime data.

Tip 3. Choose the right platform

Several blockchain platforms are available, each with its own features and programming languages. Some popular options include Ethereum, Hyperledger, and EOS. Choose a platform that aligns with your app’s requirements and your technical expertise.

Let’s elaborate with an example. Ethereum is a popular choice for developing smart contracts due to its Solidity programming language. However, Hyperledger might be a better fit for your project if you are more comfortable with Java than Solidity.

Tip 4. Design for decentralization

Blockchain is all about decentralization. When designing your app, ensure it follows the principles of decentralization.

For example, it should have no single point of failure and use distributed consensus. This will make your app more secure and give you a competitive edge in the market since users are increasingly drawn to decentralized solutions.

So, how do you design your app for decentralization? Consider using peer-to-peer (P2P) communication. Also, use a distributed network to spread the workload among nodes on the blockchain. Plus, ensure that there is no central authority controlling the network.

Tip 5. Zero compromise with security

Remember, your app will be handling sensitive data and financial transactions. There is no room for compromise when it comes to security. Here are a few things you need to focus on-

• Code optimization: Write efficient code and avoid common vulnerabilities like reentrancy attacks.
• Smart contract auditing: Thoroughly audit your smart contracts to eliminate any potential bugs or security loopholes. Consider hiring a third-party auditor for an unbiased review.
• Continuous integration and deployment: Establish robust continuous integration and deployment (CI/CD) pipelines for your blockchain application. These pipelines will automate building, testing, and deploying the application.
• Privacy-preserving techniques: Consider using privacy-preserving techniques like zero-knowledge proofs. It will safeguard sensitive data from public view.
• Interoperability: Interoperability allows different blockchain networks to communicate, expanding your app’s potential use cases and increasing its user base.
• Formal verification: Consider using formal verification to mathematically prove that your smart contracts are free from errors and vulnerabilities.
• Immutable data storage: Blockchain’s immutability can be used to store critical data, such as transaction records or user identities. This ensures that the data is tamper-proof and transparent.

All these measures will greatly enhance the security and reliability of your blockchain app.

Tip 6. Intuitive UI/UX

Even with all the best features and security, it will only be successful if your app has a good user interface or experience. Users should find your app easy to navigate and understand, regardless of their technical expertise.

Ensure a user-friendly design and layout with clear instructions and action prompts. Interact with beta testers and gather feedback to improve the user experience continuously.

You may also use visual aids like charts, graphs, and diagrams to present complex data in a more user-friendly manner.

Tip 7. Ensure regulatory compliance

Ensuring regulatory compliance is key in developing blockchain apps. Failure to follow rules can lead to hefty penalties and loss of trust.

Research and understand the legal requirements specific to the region or industry where your app will operate. This includes data protection laws, financial regulations, and any blockchain-specific legislation.

For example, if your blockchain app involves processing the personal data of EU citizens, it must follow the General Data Protection Regulation (GDPR). One of the GDPR requirements is the right to erasure, also known as the right to be forgotten.

However, blockchain’s immutable nature makes this challenging. You could design your app to store personal data off-chain to address this. It can be modified or deleted there. Meanwhile, the app can keep transaction records on the blockchain. This approach balances compliance with GDPR and the benefits of blockchain technology.

Additionally, you must understand and comply with the Anti-Money Laundering (AML) and Know Your Customer (KYC) regulations for apps involved in financial transactions.

For instance, adding an AML/KYC procedure to your app’s user registration ensures that your app meets financial rules. You could also require users to upload a government-issued ID for verification before engaging in financial transactions on the platform.

Tip 8. Test rigorously

Blockchain apps require extensive testing to ensure that they function as intended and are secure.

• Functional testing: Test the functionality of your app by simulating different user actions and interactions with the blockchain network. This includes testing for edge cases and error-handling scenarios.
• Security testing: Perform rigorous security testing, including penetration testing, to identify and address any vulnerabilities in your app.
• Performance testing: Test your app’s performance by simultaneously simulating many transactions and users. This will help identify any bottlenecks or scalability issues that need to be addressed.

Regular testing at every stage of development ensures a stable, secure, and functional blockchain app for your users.

Tip 9. Build a supportive community

One supportive community can make all the difference in the success of your blockchain app. Engage with your users, listen to their feedback and suggestions, and actively involve them in the development process.

Create social media channels or forums for discussions, updates, and announcements about your app. Encourage community members to share their experiences. Promote your app through word-of-mouth. They will also provide valuable insights for improvement.

A strong community helps with user retention and acquisition and adds credibility to your app.

Tip 10. Plan for maintenance and updates

Blockchain technology is constantly evolving, and so should your app. Plan for regular maintenance and updates to fix bugs, add new features, and keep up with the latest advancements in the blockchain space. This will not only improve user experience but also ensure the long-term success of your app.

Consider setting aside a dedicated team or budget for ongoing maintenance and updates. Additionally, communicate these updates and their benefits to your users, keeping them engaged and informed about the app’s progress.
