Do not worry, we will be highlighting and discussing 19 steps to follow in order to venture into the blockchain technology industry and become a successful blockchain developer The first step in becoming a professional developer in the blockchain industry is to earn a degree or diploma in computer science, computer engineering, computer programming, etc.
Enroll for blockchain classes and tutorials Take time to fully study how the blockchain technology works.
In-depth knowledge of data structures A prospect in the field of blockchain development should understand the basics of data structures, as well as how to apply this knowledge. Without the knowledge of different data structures, a blockchain developer will be unable to utilize advanced cryptography to design a secure and immutable blockchain.
Smart Contract Development The launching of Ethereum has greatly popularized the concept of smart contracts. Learning about smart contract development involves knowing network-specific languages such as Chaincode, Viper, and of course Solidity. Basic Understanding of Cryptography The functionality of cryptographic methods in the development of blockchain cannot be ignored.
Without a basic understanding of how these cryptographic methods are employed in blockchain development, it is impossible to venture into the blockchain technology industry. Web-Development Skills This is one of the blockchain developer skills that are useful for the basic designing of decentralized applications.
Possessing web-development skills will imply that you have the basic knowledge of both front-end and back-end development skills such as API handling, development of interactive graphical user interfaces for Dapps, and request handling amongst others. Knowing how to code Coding is definitely a necessary skill that can not be compromised when it comes to blockchain development.
Every blockchain engineer is required to know the basics of coding and how to effectively and efficiently write codes within the blockchain system. Versatility with Different Programming Languages As it has been mentioned a couple of times in this article, different blockchain platforms may have their network-specific languages.
In order to maintain your relevance as a professional blockchain developer, you have to familiarize yourself with the various programming languages that you can learn. Platforms and Networks There are several blockchain platforms and networks actively operating in the blockchain system. A prospective blockchain developer should be able to understand how each of these blockchain networks and platforms differs from each other.
Knowing their unique features is necessary. Challenges Faced by A Blockchain Developer The blockchain technology has its challenges and below are some of the issues that blockchain developers may be faced with:. The code in blockchain systems is public and visible for everyone. This means that hackers can take advantage of this to hack the system and paralyze the security of blockchain transactions. By implication, this delays the development of blockchain. Management of Resources Another challenge blockchain developers face is that they constantly have to meet up with the demands of all remote and local users with the real-time response the moment they go live.

But, third-party authorities can always create trust issues due to a lack of transparency. On the other hand, multiple parties manage blockchain data, and information is validated via an agreed-upon consensus algorithm. If you have privacy concerns, it can become possible to provide read-only and write-only permissions to a specific party using blockchain. No dependency on a central authority will reduce:. Trusting other parties is essential when doing business, especially in a partnership situation.
We have to trust banks to keep our money secure and business associates to maintain agreements. What if the trust gets broken?
Now, the question is, how would you know when to use blockchain. Though blockchain is a trustless environment, parties can work simultaneously without worrying as they have an updated ledger at all times. It uses various consensus algorithms to validate all transactions without giving more attention to any particular party.
Hence, it brings fairness to the system. Everyone considers blockchain as an immutable system as it does not allow you to change rules on the system once they are written. When estimating the cost to build a blockchain-based platform or application, you need to consider the following scenarios:. Here is our analysis of the estimated cost of blockchain development for a minimum viable product when using different development resources.
Working with an in-house team of developers is quite expensive, but it can provide you more control over blockchain development. However, you should take this path if software development is your core business. On the other hand, hiring freelance blockchain developers could be less expensive but very risky. Working with a third-party company could be a viable option if your project is enormous.
Blockchain companies are experienced and can help you at every step of the development process. When compared to an in-house development team, the cost of blockchain companies is lower. Every business requires a digital solution to run their business operations efficiently.
Building a blockchain app can build trust and offer transparency while removing additional intermediaries. Before implementing blockchain technology and estimating its cost, it is essential to understand the type of blockchain app you need.
Whether you need a permissioned blockchain app or a permissionless blockchain app, you need to consider which application can suit your business needs. Also, the cost of a blockchain application varies from industry to industry. For example, you may need an app for supply chain management, healthcare, real estate, education, and many other business domains. The cost of an app will depend on the complexity of the project.
The cost of blockchain app development also depends on the number of resources required to develop an application. Salaries of blockchain experts are the significant expenses you should not miss when calculating the cost to build an app. While investing in blockchain developers, ensure you have hired the best ones and added their salaries to the total expense. Companies might use agile methodology tools such as Jira, Confluence, and Trello to manage blockchain projects. They use such tools to test an app, track timelines, and deliverables.
Therefore, the price of project management tools is also added to the cost of blockchain implementation. Your blockchain app might require a subscription to third-party subscription tools such as bug tracking tools, notification services, amazon web services, software monitoring services, and data analytics tools.
The cost of subscription tools also contributes to the cost of blockchain app development. In this section, we have explained the process of building a blockchain-based application.
First of all, it is essential to develop a problem statement and understand all of the issues you want to solve with a proposed solution. Ensure that the blockchain solution will benefit your business abilities. Analyze whether you need to migrate your current solution to the blockchain, or you require a new application to be developed from scratch.
For example, suppose you are a healthcare provider who wants to develop a blockchain-based health record exchange app. In that case, you should know various use cases of the applications and what benefits it will offer to users. Once you decide that you need a blockchain solution for your business operations, the next step is to select the right blockchain platform and blockchain development tools for your project.
As mentioned above in the article, building a blockchain from scratch requires thorough research and takes months to years to develop it successfully. Therefore, you should build a blockchain app on top of a blockchain platform that meets your business requirements. You should identify the right blockchain platform for your application based on the factors like consensus mechanism and problems you want to solve. For example, you can build an Ethereum-based application to develop a decentralized public application with smart contracts.
When the blockchain platform is identified, you must do brainstorming and understand the exact business needs. Once you identify the blockchain platform for developing a blockchain application, you should focus on drafting business requirements and brainstorming ideas. Find what technology components should be added as off-chain or on-chain entities on the blockchain ecosystem.
Create a roadmap of the product that will help you to build an application within a decided deadline. You should come up with a blockchain model and conceptual workflow of the blockchain application. Also, decide if the application needs to be developed on a permissioned or permissionless blockchain network. It would help if you also decided on front-end programming languages to be used, servers, and external databases in this stage.
A proof of concept is done to represent the practical applicability of a blockchain project. It can be either a design prototype or a theoretical build-up. In Theoretical Build-up, each project requires theoretical cases so that users could understand the applicability and viability of the product. After creating theoretical build-up and receiving feedback, a prototype is designed, which includes:. When the client approves the PoC, the next step is to prepare technical and visual designs for the application.
Since you have planned an entire application at this stage, start creating UIs for each software component. Designs APIs that will be integrated with user interfaces to run an application at the back-end. Once the admin consoles and user interfaces are designed, the application gets ready for development. Development is the significant phase of the blockchain development process, where you should be ready to build the blockchain app.
In this specific stage, you either have to develop or integrate APIs for particular use cases of the application. The application is built under multiple versions. Once the client approves it, the application moves to the next stage, i. But, the software might not comprise all the features at this stage. After the alpha version is released, the app is prepared for the beta version. During Beta Phase, the software application has the complete feature set but with some unknown bugs.
Developers share the beta version with a particular group of people outside the organization to test its functionality. Once the beta version is approved and tested, the application moves to the Release Candidate version, which is an advanced beta version that is ready to be a final application and can be launched. After thorough testing, the application moves to the production phase and gets ready for delivery.
Before an app goes live, you should deploy it on the test network to carefully test its functionalities. When deploying an application, administrators can also manage which versions of the app need to be deployed to various resources with provisioning.
Once an application is provisioned, it needs to be hosted on the main chain. If your blockchain app is a hybrid solution, i. The application should be able to upgrade according to any new business needs and prioritization. For instance, if you need to upgrade the smart contract, later on, you should be able to deploy the new contracts without any difficulty. Developing and deploying an app does not mean you are done. Instead, a software application needs to be maintained post-development to ensure that it works with all types of upgrades in the future.
An Ethereum client, Geth, is used to run Ethereum nodes in the Go programming language. It has the ability to manage a large number of users across a blockchain network in real time. And in this way, it enhances the usability of the blockchain ecosystem. Golang or Go is one of the top programming languages used to create hyperledger fabric and other decentralized solutions.
It is a statically-typed language that comes loaded with various advanced characteristics and features, namely generics, constructors, annotations, classes, exceptions, and inheritance. It is lightning fast, highly efficient, and offers facility to manage remote packages because of the smart implementation of channels and interfaces. This again adds to the reasons why Go is a perfect addition to this blockchain programming languages list.
Created back in , Python has gained huge momentum in the marketplace, especially because of their role in AI app development. However, this is not the end of the story. A few reasons behind which is that it has easier syntax and exclusive features, along with the capability to be used both at the compilation and running time.
The noncompiled form of the language can be used to develop sophisticated blockchain apps for the logistics and agriculture domains.
