Blockchain Developers (2023)

Updated: December 18, 2023

This guide will walk you through what a blockchain developer is, how they work, and how you can benefit from using them.

A blockchain app developer is a software developer who specializes in creating decentralized apps using the power of blockchain technology.

The process involves building and deploying smart contracts on a blockchain platform, such as Ethereum or EOS, and developing user interfaces that interact with the blockchain.

App developers must have a solid understanding of blockchain principles and programming languages like Solidity and JavaScript to succeed in the role.

What is a blockchain developer?

Blockchain is a decentralized digital ledger that records transactions on multiple computers both securely and transparently–it was originally created for the digital currency Bitcoin, but many other industries have since adopted it.

A blockchain app developer itself is a software developer who specializes in creating decentralized apps using this technology.

Mobile apps are increasingly using blockchain technology to create new business models and improve the security of their services.

For example, developers are using blockchain to integrate cryptocurrency payments into their platforms. This allows users to send and receive payments securely (and instantly), without the need for a central authority to verify transactions.

How does blockchain app development work?

Blockchain app development can be complex. Here’s a simplified overview of how it works:

1. Define the requirements – The first step in blockchain app development is to define the requirements of the app. This includes identifying the target audience, features, and functionality.

2. Choose a blockchain platform – The next step is to choose a blockchain platform to build the app on. There are several options available, including Ethereum, Hyperledger, and Corda.

3. Design the app architecture – Once the blockchain platform has been chosen, the app architecture must be designed. This includes the user interface, database design, and smart contract development.

4. Create the blocks – The next step is to create the blocks that will store the data on the blockchain itself. These blocks are created using cryptographic algorithms that ensure the data stored in the block is secure and “tamper-proof”.

5. Link the blocks – After the blocks have been created, they must be linked together to form the blockchain. This is done using a hash function that creates a unique identifier for each block.

6. Add the blocks to the chain – Finally, the blocks are added to the blockchain. Each block contains a reference to the previous block in the chain, creating an unbreakable chain of blocks that cannot be altered or even deleted.

Overall, blockchain app development is a complicated process that requires a deep understanding of blockchain technology, cryptography, and software development.

That said, with the right skills and expertise, developers can use blockchain technology to create innovative, top-notch apps that stand out from the rest.

What do blockchain developers do?

The terms general blockchain developer and blockchain software developer are often used interchangeably, but there can be some key differences in their roles depending on the context.

General blockchain developer

A general blockchain developer is someone who has a broad range of skills and experience in building blockchain-based systems.

They have a deep understanding of the underlying technology and are capable of working on various aspects of a blockchain project, including designing, coding, testing, and deploying.

Blockchain software developer

A blockchain software developer may have a more specialized role in the development process. They may focus on writing and testing the code that runs on a blockchain network, such as smart contracts or decentralized mobile apps.

They may also be responsible for integrating blockchain tech into existing systems or developing custom solutions for specific use cases.

Both types of developers require a strong understanding of blockchain technology, as well as proficiency in programming languages such as Solidity, Java, or Python.

They also need to be familiar with blockchain platforms and frameworks such as Ethereum, Hyperledger Fabric, and Corda, among others.

What are the benefits of hiring blockchain app developers?

Hiring blockchain app developers can bring numerous benefits to your app business, including decentralization, scalability, security, fraud reduction, and increased app efficiency, as well as being cost-effective too.

We’ve detailed the key benefits below.


With decentralized blockchain technology, you can store data securely and transparently without relying on a central authority.


By leveraging blockchain technology, you can improve the scalability of apps significantly.

For instance, the faster and more efficient processing of transactions will boost an app’s overall scalability.

Additionally, blockchain technology enables the use of smart contracts, which are self-executing contracts that can automate various business processes, reducing the need for manual intervention.


Security is one of the most significant benefits of blockchain technology.

Blockchain networks use advanced cryptographic techniques to secure data and transactions, making it nearly impossible for attackers to tamper with app data or steal sensitive information.

Reduce fraud

Blockchain technology can be a powerful tool in reducing app fraud.

The decentralized and transparent nature of blockchain networks makes it difficult for fraudsters to manipulate data or transactions, as all transactions are recorded and verified by multiple nodes in the network.

Increase app efficiency

Blockchain technology has the potential to significantly improve the efficiency of apps across various industries.

The decentralized (and distributed) nature of blockchain networks can enable faster and more efficient processing of transactions, reducing the need for intermediaries and speeding up business processes.


By eliminating intermediaries, such as banks or payment processors, blockchain technology can reduce transaction fees and processing costs, making it a more cost-effective solution for businesses.

How much does blockchain app development cost?

It varies greatly. The factors that impact blockchain development costs depend on the nature and complexity of the project, the specific industry, the type of blockchain app required, and the use of third-party tools and integrations.

We’ve detailed each for you below.

Complexity of the app

The complexity of an app can vary depending on several factors, such as the number of features it offers, the size of the development team, the technology stack used, and the overall scope of the project.

Developing a complex app requires a lot of planning, coordination, and effort to ensure that all the components work seamlessly together.

The specific industry

The specific industry that an app is developed for can impact its complexity. For example, some industries, such as healthcare or finance, often require apps to adhere to strict regulations and guidelines, which can add an extra layer of complexity to the development process.

Other industries, such as gaming or social media, may require more focus on the user interface and user experience to ensure that the app is engaging and intuitive.

The type of blockchain app required

There are several types of blockchain apps, each with its own unique features and requirements.

For instance, a cryptocurrency wallet app may require complex security protocols to protect users’ digital assets, while a supply chain management app may require integration with existing systems and databases.

Developing a blockchain app requires a deep understanding of blockchain technology and its underlying principles.

Third-party tools and integrations

Many apps require integration with third-party services such as payment gateways, social media platforms, or analytics tools. These integrations often require additional programming and testing to ensure that they work seamlessly with the app’s existing features.

In some cases, third-party tools may require the use of APIs or SDKs, which can add an extra layer of complexity to the development process.

Average costs

Average costs for blockchain app development can be found below:

  • Low-complexity apps – ranges between $30,000 and $60,000.
  • Moderately complex apps – ranges between $60,000 to $150,000.
  • High-complexity apps – ranges between $150,000 and $350,000.
