Milestone 1: Glossary Basics
Now that you have your blockchain instance up and running, it is now time to manage the application programming interface APIs. There are already pre-made APIs depending on the platform of your choice. This means that some platforms might not offer APIs at all. So, why do you need API for? Well, you need them to do the following. With the backend setup, it is now time for you to design the interface for the admin and the users.
For the admin interface, you need to provide as much information as possible to the admin while making sure that you do not overwhelm the interface with unnecessary information. For the user, you can decide to showcase the important things only. If you are in a permissioned network, you can decide to show them KYC information, their status with the network, their roles, and other vital information. You can use any of the front end programming languages out there.
The last step is to finalize the project. Here, you need to ensure that your blockchain network is running as intended by monitoring it non-stop. Also, make sure that you keep working on your blockchain network. You may also want to add future tech to your blockchain such as analytics, cloud, artificial intelligence, and so on! In this section, we will cover important points about creating a blockchain for financial products.
Financial products are different compared to other types of products and hence require different forms of planning and execution. Infact, the financial sector is the most-ready industry out there that is ready for blockchain. Even the first use case for blockchain is a crypto-coin bitcoin which changes how two parties connect and transfer funds to each other.
FinTech is one of those sectors that always suffer from some sort of fraud or foul play. This is because of the fact that people are willing to do the wrong things just to make more money. By using blockchain, parties can work without any intermediaries and hence can save energy and cost associated with doing the transaction. But, not every fintech product should adopt blockchain so early.
Below are the reasons why you should try to invest in the blockchain:. There are of course many cases where blockchain is not a good option.
For example, if you are limited in your resources, then it is not wise to go for blockchain. Blockchain engineers are not cheap and it also takes a lot of effort to maintain the blockchain. Also, a blockchain implementation means a lot of changes to how operations work, and that could be too much for employees or the end-users who interact with the system. Lastly, it is not advisable where your Fintech product is looking for short-term goals.
Blockchain, due to its implementation difficulty and cost involved, makes it always a long-term strategy for any business out there.
Well, if you are someone who wants to get into the nitty-gritty of creating your own blockchain, then this section is for you. The good news is that we have already written a complete tutorial on how to build a blockchain in Python. Check out the infographic we created to give you a glimpse of what you can expect from the tutorial. So, what do you need to get started? Fortunately, there is hope!
Here are some steps that anyone coming from such a place, but yet is interested in a Blockchain developer career can take. Upskilling is the process of teaching an employee new skills. This process is particularly useful when it comes to creating new Blockchain developers from other, similar positions in the business.
Some companies, keenly aware of the growing importance of the Blockchain technology , will upskill individual employees, empowering them to handle the new tech. If the prospect of getting in on the ground floor of this exciting innovation appeals to you, then you may wonder what the next step is. Whichever the method, you will benefit from 32 hours of instructor-led training, over 50 hands-on exercises using Blockchain technology, nine practical projects are covering Ethereum, Bitcoin, and Hyperledger, and 24 x7 assistance and support.
It should be mentioned that the Corporate Training solution is ideal for businesses that want to upskill chosen employees and make them into Blockchain developers. Once you complete the course, you will have certification in Blockchain development, and be ready to take on the new challenges of this exciting technology.

Check out Simplilearn and get started on a new, rewarding, and profitable career! John Terra lives in Nashua, New Hampshire and has been writing freelance since Besides his volume of work in the gaming industry, he has written articles for Inc.
More recently, he has done extensive work as a professional blogger. His hobbies include running, gaming, and consuming craft beers. His refrigerator is Wi-Fi compliant. The transaction on the blockchain is made through bitcoins and other cryptocurrencies. The blockchain technology is said to be decentralized as there is no central authority that covers these things.
All the blockchain blocks are connected to one another in the system and get the information that a transaction is being done. However, no one gets the information about the person making the transaction. In case of the blockchain technology, the blocks are mined and the users mining them are called miners.
The sphere of the blockchain technology is much wider than human imagination and therefore it is advisable to go through the blockchain glossary here.
And to have an in-depth understanding of what blockchain technology actually is all about, go through our guide here. Just like any other mobile application, Blockchain apps also have a structure that includes coding for the front-end and back-end, too. However, you will come across tons of challenges.
But before presenting you with the coding blocks, here are some of the main keywords you should remember:. The genesis is the very first block. The thing that makes it special is that it does not point to the previous block as every block in the blockchain structure does. To add the blocks, we need to know which is the last block in the current blockchain technology.
For the same, we used the following functionality. By far we know the hash value of the last block is the same as the value of the currently created block. So, how can we find out these values?
Simply by measuring their values. Now it comes to checking the validation and the stability of the codes and for the same, the coding goes as displayed below in the table. In this part of the code we are defining two terms, current block and previous block.
And now we are simply going to find the hash of these two values. As explained above, the previous block value must equal the value of the newly created one and in this case, if the value is met, the function will return true. In case, the value is not met, it will return to being false. And now you are done with the basic blockchain application. We just successfully coded a new blockchain-based cryptocurrency and that is named as BlockGeeksCoin.
Here, the Genesis block was developed automatically once the constructor was activated. Smart contracts facilitate the exchange of money, property, and other valuable objects without the involvement of a middleman. Smart contracts need to run on multiple nodes without compromising on integrity. The infographic below gives an insight into how the technology works. Blockchain based applications offer ample of benefits from transparency and decentralization, to easy accessibility.
Blockchain apps offer ultimate transparency as there is no involvement of middlemen in any of the transactions. However, the level of transparency may differ from one observer to another. When a transaction is made by one party to another, the transaction remains transparent to everyone, i.
If you are in a permissioned network, you can decide to show them KYC information, their status with the network, their roles, and other vital information. You can use any of the front end programming languages out there.
The last step is to finalize the project. Here, you need to ensure that your blockchain network is running as intended by monitoring it non-stop. Also, make sure that you keep working on your blockchain network. You may also want to add future tech to your blockchain such as analytics, cloud, artificial intelligence, and so on!

We already covered in detail on how to choose the right BaaS platform for your business. Check out the infographic below to get a good glimpse of what to expect.
We know that if you are reading this article, you are either a business or an aspiring learner who wants to become a blockchain developer.
The good news is that we already covered a plethora of blockchain developer content on our site. Check them out below. This leads us to the end of how to create a blockchain article. We covered quite a bit of content and tried to look at the question from both the learner or a business perspective. So, what do you think about creating your own blockchain?
Comment below and let us know. Nitish holds a BSc in computer engineering. He is a blockchain enthusiast and in spare time likes to read about the moon. His articles have published on Dzone, InfoWorld, and Hongkiat. Fortunately, there is hope! Here are some steps anyone coming from such a place, but interested in a career Blockchain developer can take. One of the biggest hurdles to anything new and revolutionary, such as blockchain technology, is getting used to the various concepts that are indispensable in the system.
Otherwise, you will be very out of place in your learning process. If you are interested in the technical aspects of how to create a fin-tech application on Blockchain then you should definitely take in a deep understanding of token economics.
This difference in knowledge is extremely obvious when you research some floating ICOs. It is very clear that the economic side of their ICO is not well thought-through. After that, you should understand how Bitcoin works.
Bitcoin is the most popular in blockchain and has a sizable influence on the crypto market. Now congrats, you have finished the first milestone. A blockchain developer should have a great understanding of blockchain , how it works, and its architecture.
They need to have at hand concepts such as cryptographic hash functions, consensus, distributed ledger technology. Second, in-depth knowledge and applicability of data structures are essential. Blockchain developers are constantly learning and tuning existing data structures like Merkle tree , Patricia tree , etc. Blockchain uses a lot of data structures combined with advanced cryptography to build a secure and immutable system.
Knowledge of blockchain, without any knowledge of data structure, can only be considered incomplete. Blockchain is a combination of advanced cryptographic and data structures, so it is clear that you also need to have a good grasp of cryptography. Lots of cryptographic methods, like hash functions SHA and KECCAK, are used in blockchain in addition to asynchronous cryptography to generate digital signatures.
Without understanding how these things work, it is impossible to become a blockchain developer. Blockchain is a combination of advanced cryptographic and data structures. Smart contracts have become a huge thing since Ethereum was launched. Every blockchain now tries to incorporate smart contract functionality into its system. Smart contracts enable business logic to become appliable to the blockchain. Therefore, developers trying to get into the blockchain field should definitely learn about smart contract development.
This usually requires learning network-specific languages like Solidity, Viper, Chaincode, etc. If the prospect of joining the ground floor of this exciting innovation appeals to you, then you might be wondering what the next step is. For every year blockchain developer job in the industry, only one blockchain developer is eligible. Many asset companies like IBM, Accenture, and Capgemini are on the hunt for qualified blockchain developers.
In Vietnam, blockchain development companies are thriving and competing with other markets around the world.
What It Takes To Be A Blockchain Developer
So, you need to make sure that investing your resources and precious time in a blockchain business makes sense for you currently. 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, how to develop blockchain. No develop on a central authority will reduce:. This is great for applications that will need to process a lot of transactions per second! Their area of expertise is versatile, and it covers fields such how Education, Blockchain, Finance, etc.

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.
Remix IDE is a compiler used for small contracts. It is a browser-based tool used to create and deploy smart contracts. You can use Remix IDE to write, debug, test and deploy smart contracts using the Solidity programming language. Remix can connect to the Ethereum blockchain via Metamask. Before using Ethereum, you should have a place to store Ether tokens and execute smart contracts. Mist is the Ethereum wallet used for smart contract deployment and is available for Mac, Windows and Linux.
While installing Mist, remember once you set up the password, you cannot update it again. Create a strong password and never forget it. It allows users to make calls to the blockchain without the need to run an Ethereum node.
GanacheCLI is used for the instant mining of transactions. It is an easy-to-use API that provides you with an overview of test chain events. Security plays a prominent role when it comes to building a blockchain application. You need to ensure that the Solidity code does not have security holes.

This type of blockchain developer will also be tasked with the responsibility of supervising the whole network and driving advanced decisions associated with blockchain technology.
This second type of developer is responsible for the development of smart contracts, interactive front-end designs for decentralized apps, and back-end blockchain. A blockchain software developer will also supervise the whole stack operating their Dapps. A blockchain software developer employs the structure and mechanisms designed by the core blockchain developer to develop decentralized applications that operate on blockchain networks. It is necessary for blockchain developers to possess a significant and applicative understanding of the structure and modes of operation of the blockchain.
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. Coding Language It is necessary for the coding language to be versatile. This is because certain codes can be executed parallel, while others can not. The differences in programming languages when it comes to parallel processing is a challenge that blockchain developers are trying to resolve.
Separation It is expected that every transaction in every situation should have the same outcome. In the same manner, smart contracts should also be deterministic. Blockchain developers should separate transactions and smart contracts from non-deterministic factors.
