How To Become a Blockchain Developer: A Step-by-Step Guide
Come up with a real challenge. At the beginning there was the idea… Before building your own decentralized application , it would be very wise of you to define a bunch of issues and decisions to solve them. In other words, you need to determine why you actually need a DApp. The point is, some potential issues you may face can be solved without blockchain. So, you need to make sure that investing your resources and precious time in a blockchain business makes sense for you currently.
If the analysis indicates that using a blockchain application is a good idea , move to step 2. Develop an appropriate consensus mechanism. To create a blockchain app, you need a system of linked parts to validate transactions and maintain a consensus mechanism.
In most cases, Bitcoin is used as a sample. Make sure the method you choose meets your requirements in the best way. Choose a platform. The easiest way to get yourself a DApp is to build one on an existing platform.
These days, the most popular of them are:. No doubt, this is one of the best known blockchain platforms. It can boast of an extended infrastructure that makes it possible to create smart contracts and deploy decentralized apps. To use Ethereum, you need to "speak" Solidity. It is oriented towards the corporate segment.
The platform requires Go, Java and JavaScript for app building. One of a new breed of blockchain platforms. Unlike its counterparts, Cardano has two development layers: one is related to ADA cryptocurrency ; the other one is for smart contract processing requires Haskell.
Don't forget about your User Interface and Admin Console. That's all you need to know! Make your application user-friendly and easy-to-maintain. Believe it or not, the importance of those two features can't be overestimated. Skills and practical experience: things you can always rely on. To build a DApp from scratch, you need to consider lots of things, some of which can seem secondary and insignificant.
Still, the main rule here is, the more you know, the more you grow. So, here we give you a few pieces of advice from the experts that can be useful for both experienced app developers dreaming of the blockchain industry and for those who are at the start of their developer career. Spend some time to understand the working principles of blockchain.
Before you dive into the exciting world of DApp development, you will need to know the nuts and bolts of blockchain basics. Get familiar with Truffle and Solidity. To succeed in blockchain app development, you need to spend some time learning programing languages like Solidity. Also, you'll need to know more about popular frameworks. Ethereum's Truffle is one of them.
Don't hesitate to use step-by-step guides in order to become a true guru. Gain experience by developing blockchain… games. Isn't that awesome to create an army of zombies and fight a war on a blockchain? Sounds great, indeed. The most important thing is that it's possible with Solidity! Such an approach will help you to understand that blockchain can be used not only for smart contracts and financial transactions, but for exciting diversions as well. Thinking outside the box can help you to create really amazing ideas.
Keep in mind: networking is a key. If you're OK with that , try to attend a local blockchain meetup or network with blockchain developers online. Reddit, Gitter or Slack make good places to start. Don't be too lazy to learn. Oh yeah, what else is new? However, lots of people forget to give themselves enough time to update their " database ". Main types of blockchain apps 3. A short guide on how to create a blockchain app 5.
Come up with a real challenge 6. Develop an appropriate consensus mechanism 7. Choose a platform 8. 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.
Using Geth, users can mine Ethers, create smart contracts and run them on EVM, explore the block history and send tokens between addresses. Geth can be downloaded and installed on Linux, Windows and Mac. It supports two types of installations, Scripted and Binary. Once you start using the Geth, you either have an option to create your own blockchain based on the provided settings or connect to the existing blockchain.

A development framework for Ethereum-based dApps, Embark, is used to build and deploy dApps and enable you to create smart contracts written in Javascript programming language.
If an application contains multiple contracts, Embark can also handle the migration of smart contracts. Developers can manage contracts on multiple blockchains such as live network, testnet and private net using the Embark framework.
It is a wallet that connects Chrome or Firefox with Ethereum blockchain by acting as a browser extension. It can save keys for Ether and ERC20 tokens. It can be installed simply as a Chrome extension.
Since blockchain is immutable and transactions once added to it cannot be updated or removed, untested programs can result in high costs. That is why it is essential to test a decentralized application before it is deployed on the mainnet. Ensure to test your app on Blockchain Testnet before going live. Truffle is a framework for Ethereum that provides a development environment.
The framework supports a library which can link complex Ethereum apps and offer custom deployments to make contracts coding simpler. It supports some of the features mentioned below:.

The importance of blockchain in cryptocurrency, that's popularity is soaring, is the main reason why so many people wonder how to become a blockchain developer. There's quite a bit of info you should know, so let's try to put it down easily.
Someone who builds on a blockchain is called a blockchain developer. Would you like to learn how to become one? Of course, you would! Everything you need is freely available on the internet. Blockchain is open-sourced. If you want to learn how to become a blockchain developer, the first thing you need to understand is the basics of blockchain technology.
Are you ready? A blockchain is a digital database for storing information. A blockchain is a bit like an Excel spreadsheet. However, blockchains have some very special features that make them different. Blockchains are:.
This Udacity New Year Sale is active for a limited time. Decentralized One of the many points you should discover on your way to learning how to become a blockchain developer is that it is decentralized. It is stored across many different computers. These computers are called nodes. Blockchains are called peer-to-peer networks because there are no third parties like Microsoft, Google, or Facebook involved.
So, not one single entity has control over the data on a blockchain, users and every blockchain developer deal with each other directly instead of through a third party. Public All the information on a blockchain is public. This means everyone can see it.
Guided by Consensus This means that before new information is added to the blockchain, more than half of the nodes have to agree that it is valid before it is added. It protects the blockchain from fraud. Information on a blockchain is protected. This means that it is encrypted and nearly impossible to hack. These blockchains are designed to have all kinds of dApps built on them. Bitcoin was designed as an alternative to centralized banking.
So, it's highly beneficial to learn how to become a blockchain developer if you want to create something equally as great. The second step is deciding which blockchain you want to develop on. Two of the most popular development platforms are NEO and Ethereum. Looking for more in-depth information on related topics? We have gathered similar articles for you to spare your time.

Ethereum was created by Vitalik Buterin and went live in It became NEO in Both platforms allow users to build dApps. They do this in slightly different ways. DApps are built using programming languages , just like regular software.
These are popular languages that most software developers know how to use. This makes using NEO easier for experienced users. Ethereum has its language called Solidity.
This means that even experienced developer needs to learn a new language to be a blockchain developer and start building dApps. Don't let that deter you from learning how to become a blockchain developer though.
NEO is focused on providing platforms for the digital businesses of the future. It follows Chinese business regulations and works closely with the Chinese government. It is also currently a faster network than Ethereum.
This is great for applications that will need to process a lot of transactions per second! Ethereum also has links with big businesses like Mastercard and Samsung. However, Ethereum is more focused on encouraging users to develop the blockchain than NEO is. It also has the largest dApp building community of any other blockchain. This is why I believe Ethereum is the best platform for a newbie to start their development training.
Solidity was developed by an Ethereum team , which was led by Dr. Gavin Wood in Solidity is used to write smart contracts. Smart contracts are used to create dApps. It's vital to understand smart contracts if you're curious about how to become a blockchain developer. Smart contracts are the rules which guide transactions on Ethereum's blockchain.
If the conditions of a smart contract are met, the transaction will happen.
