Critical Facts When Hiring Blockchain Developers (Part 2)

Developing apps on blockchain technologies is challenging since building a network of nodes takes a while. The creation of this network is a complicated task, so it can be slow and challenging to do.

If you want to build a blockchain network, you will have to choose the right tool. There are several tools to choose from, each with its benefits. This is why you should select the one that seems the best for your business or organization.


This tool is one of the most widely used for building blockchain solutions. This tool is available in the Hyperledger Fabric and Hyperledger Composer. Hyperledger Fabric offers a modular blockchain architecture. It’s also a platform that lets you develop blockchains quickly and easily.


Ethereum is an open-sourced blockchain-based distributed computing platform that provides a virtual machine. A virtual machine executes smart contracts. Smart contracts are applications that run as they were programmed without any possibility of downtime, censorship, fraud, or third-party interference.

Since smart contracts require lots of code, developers can utilize solidity, a contract-oriented programming language used for implementing smart contracts. They developed this language for Ethereum based on the API of the existing language Serpent.

Open Chain

This is a private blockchain solution that IBM developed. This solution combines two similar projects: the open-source Hyperledger Fabric and the private blockchain solution of IBM. This solution can significantly reduce the efforts required for building a blockchain solution and help you create a private blockchain network within a few hours.

These are the top three tools you can use to develop blockchain networks and applications. You’ll have to choose the tool that meets your company’s needs.

Coding Challenges

The development of blockchain-based applications comes with a variety of different challenges. Some of these challenges relate to the need to upgrade and update technologies, while others relate to creating the product correctly.

You’ll be using various tools and methods for testing, debugging, and refining your product since blockchain is a relatively new technology. Nobody has ever used it on a large scale. This means that you’ll need to use various methods to test, debug, and refine your product.

Finding the Right Team

You’ll need to find a team that has a lot of experience in app development and blockchain development and the programming languages used in the development of smart contracts.

This is the most challenging part of developing blockchain applications, but it can often be the most important. If you don’t choose the right team, your project won’t be successful, no matter how well you develop it.

Debugging and Testing

When you’re using blockchain technology, many things can go wrong. You’ll need to ensure that your product is working correctly and without bugs.

When you’re testing your product, you should use various methods. You’ll need to try it both manually and automatically. You should simulate your users’ actions and ensure that your application is working as you intended.

Creating Your Blockchain

When you’re developing blockchain applications, you’ll have to create your blockchain. This means that you’ll need to build a blockchain from scratch. This can be challenging, especially when you don’t have any experience with it.

To create a private blockchain, you’ll need to use a reputable blockchain framework.

Understanding Blockchain Development

Blockchain is a new technology, which means that there is a lot of confusion and misunderstanding surrounding it. Many people don’t understand what it is and why it’s useful. You’ll need to spend some time understanding this technology.

Adopting Blockchain Technology

The last challenge that you’ll have to face while developing blockchain applications is the challenge of adopting blockchain technology. Many people are skeptical when it comes to blockchain technology. You must educate your users and convince them that your product is trustworthy.


The blockchain contains a lot of growth potential. Many companies are investing in this technology because they believe it can change the world and innovate the economy. If you’re thinking about developing blockchain applications, you’ll have to be prepared to face many challenges. However, it’s also an enriching experience.
