    The roles can be as expansive as any in tech from developers, engineers, coders, analysts, business managers, etc. How were they created? What do they aim to achieve? What are the current use cases? Read some whitepapers, learn about the underlying principles and economics, set up a wallet and buy some cryptocurrency.

    Take a deep dive into smart contracts and distributed applications DApps. While there can be a steep learning curve initially, before you know it, concepts like private and public keys, digital signatures, proof of stake, and proof of work will become clear. There are numerous blockchain development platforms today that are helping businesses and developers build new blockchain applications and invent new use cases with the technology. There is no single language for developing on a blockchain.

    Different blockchain platforms and tokens are built with different languages. For example:. To be clear there are two distinctions worth understanding: developing a blockchain vs developing for a blockchain such as DApps.

    For developing on the blockchain — it really depends on what you are building, usually, a smart contract just handles transactional logic for example. Beyond that, it really depends on what best compliments your existing skillset and captures your interest. Security-first is essential, as smart contracts are prone to vulnerabilities and exploitation. Many more complex DApps still need to use existing storage options for performance reasons.

    According to Chris Ward, who works for the Ethereum Foundation and Kauri, the best thing about being in the blockchain space is getting to create new tech paradigms:. You attempt to break apart the traditional promise of centralised computing. You also need an eye for security because if you get it wrong you can have a lot of potential problems. As you can see from these excerpts from roles advertised, the blockchain developer space is broad and encompasses a diverse range of skills, competencies, and interests:.

    Developers and product owners on Greenfield projects which will involved building and maintaining automated testing solutions. As a junior Tester, the company is not looking for much experience; only for a hungry and smart tester with demonstrable experience of your passion for testing. Finally, they operate on multiple systems and apply knowledge of one or more platforms and programming languages.

    Of course, obstacles are awaiting the Blockchain developer. For instance, the developer has to work with legacy infrastructure and its limitations, while still meeting the expectations inherent in a Blockchain development project. Also, there are the challenges of understanding the technical practicality of implementing decentralized cryptosystems, processes that fall outside of the traditional IT development skill-set, which means a Blockchain developer needs specialized skills.

    So, after all of that, the questions present itself: with all of these responsibilities, how does one train someone with the necessary skills to let them rise to the challenge of Blockchain development? There are two different situations at work here. There are the Blockchain hopefuls who are starting completely from scratch, having no background in programming whatsoever, and those who have experience in careers that share similarities with Blockchain. Before we dive into those two different types of people aspiring to become Blockchain developers, it may help to familiarize ourselves with the kind of mindsets that are best suited for Blockchain developers.

    After all, the unique challenges of Blockchain development require a certain unique way of thinking. Furthermore, a good Blockchain developer works well with a team and can collaborate.

    On a related point, the ideal Blockchain developer knows when to ask for help with a problem and when to keep plugging away by themselves until they arrive at the answer.

    So the best candidate for Blockchain development works well with others, knows his or her limitations, and can unconventionally approach problems. 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.

    Please apply for immediate consideration. One of the great things about blockchain technology is that you can hit the ground running with a plethora of mostly free resources including tutorials, videos, webinars, and training.

    The best way to learn is through doing, and connecting with others with interests in blockchain. Talk to people on Reddit, Slack, and Git. Every week there are events, meetups, conferences, and webinars.

    All you need is time and interest. Conceptually, blockchain is an emerging discipline and the use cases and technologies are ever-evolving. It moves fast with some unpredictability. But if you possess a genuine interest and a willingness to learn, you might just find the most rewarding career of your lifetime. Share and learn. One of the biggest hurdles with anything as new and revolutionary, such as the blockchain technology, is familiarizing oneself with various concepts integral to the system.

    If you are a beginner, then there are certain terms that you need to be familiar with:. It could be advisable to learn more about these terms that are widely used in the crypto-sphere. It is highly recommended that you go through our comprehensive glossary. It is important to learn these basic terms otherwise you will be very lost further on in your education. Now, up next, it is time to educate yourself some more on the technical aspects of the blockchain.

    If you are interested in the technical aspects of how to create a fin-tech application on top of the Blockchain then you should definitely learn the ins and outs of crypto-economics. This difference in knowledge is extremely apparent when you study some of these ICOs floating around. So, in light of that, it can be a good idea to read up a bit on economics and have a general idea of it. If you want to learn about crypto-economics in general, then you may check out our article here.

    If you are intrigued by the cryptography specifically and want to know how signatures work and what public-key cryptography means, then read this.

    After that, it is highly recommended that you understand how bitcoin works. You can even call it the finest example of what the blockchain technology can achieve purely because of the impact that it has had. You can find it over here. Now that completes the first milestone. How can you possibly innovate and improve upon a platform when you have not used it even once? Go to Coinbase or any other exchange that you are comfortable with or is accessible in your country and buy some coins.

    It is extremely straightforward. Since you are not going to be buying a lot of coins then simply use a basic online wallet. These wallets are the easiest to use among all. Furthermore, you can access this wallet from any server or any device in the world as long as it is connected to the net. Having said that, there is one big problem when it comes to online wallets. Your private key is going to be saved on another server. This is basically like serving up your key to hackers on a silver platter.

    Do NOT use online wallets to store huge amounts of your money. Store the bare minimum that you need for exchange purposes. As you create an extensive portfolio, you must learn how to utilize cold wallets to store your money. You can learn how to do so here. As a blockchain developer, you will face tons of challenges in the back-end. Creating and maintaining a public blockchain is not easy because of a number of reasons.

    Blockchains, as David Schwartz puts it, should be fortresses. Firstly, the code is public and open for all to see.

    Anyone can look at the code and check for bugs and vulnerabilities. However, unlike other open code resources, the downside of finding vulnerabilities on blockchain code is massive. Any programmer can hack in and get away with potentially millions and millions of dollars. Because of these legitimate security concerns, development on the blockchain is usually very slow. It is important to keep pace with the network.

    You cannot fall too far behind and not keep up with all the network demands. You should be well equipped to handle remote and local queries.

    The blockchain must always perform at its highest possible capabilities, but for that to happen the language chosen must be extremely versatile. All that you need for signature verification is the key, transaction, and signature.

    With just three data you can conduct verifications in a parallelized manner. However, not all the functions on a blockchain should be done that way. Think of transaction execution itself. Some languages are good at parallel operations while some are good in non-parallel operations.

    That is called deterministic behavior. So, in blockchain development, all transaction operations must be deterministic. You cannot have a transaction that behaves one way and then behaves another way the next day. Similarly, you cannot have smart contracts that work in two different ways on two different machines. The only solution to this is isolation. Basically, you isolate your smart contracts and transactions from non-deterministic elements. There are some languages that fulfill most of these needs.

    Javascript is usually used to create highly interactive web pages. How do we make a block? What does a simple block consist of? Before we continue. You need to understand certain terms that we are going to use in our program:. Ok, so this right here is out a block. So, in the first line of the code, we called the crypto-js library because the sha hash function is not available in JavaScript. Next, we invoked a constructor inside the class to call for objects which will have certain values.

    The thing that probably catches your eye is the calculateHash function. In a block, we take all the contents and hash them to get the hash of that particular block. We are using the JSON. Ok, so we have the block ready and good to go. So, the moment a new chain is created, the genesis block is invoked immediately. Firstly, we will need to know what the last block in the blockchain currently is. For that we use the getLatestBlock function. So, what is happening here?

    How are we adding the blocks? How are we checking if the given block is valid or not?
