    Now that big business has caught on to the many applications and usefulness of blockchain, these few skilled blockchain developers are hotly sought after by companies who are finally jumping on the bandwagon and trying to integrate the technology into their services. All of this, he says, pales in comparison with the nine million Java developers worldwide, and about The rapid rise of blockchain has created a skills shortage, as demand far outstrips the number of talented and experienced individuals who can undertake the tasks that companies are working on.

    Because of this, it is incredibly difficult for a business to find the right blockchain developer for their needs. Recruiting these sought-after individuals is proving incredibly challenging for both startups and established corporations. Until recently, blockchain technology was only a fringe-technology explored by a small but enthusiastic community.

    Because of this, blockchain developers tend to be different from other employees. Their unique situation means that HR needs to try new tactics in order to find the best blockchain developers. Consider the different aspects of your company, as well as the kind of blockchain project you are embarking on. There are many factors that will affect what kind of developer you will hire, such as the type of project, its length, the number of people you need, whether you need experts in the field or just enthusiastic individuals whose skills you can develop.

    It may even be better to outsource the project to a specialist blockchain development firm, or even this collaboration between Microsoft and ConsenSys. Outsourcing can relieve you of the hiring pressure and allow your company to focus more on its core services.

    The individual characteristics will act as a filter for those who want to be part of your project. It will also influence what you will have to offer them in order to get them onboard. If your project appeals to the blockchain developer mindset, you will probably find it much easier to find the right staff. Great blockchain developers can be very different from the rest of the workforce, even those within the IT sector.

    This is because blockchain technology was an outsider interest that has only just begun to have a real commercial impact in the last couple of years. The result of this is that the best and most experienced developers tend to be in it for the passion, while other strong candidates are entering the industry because they see great opportunities in blockchain technology. The early Bitcoin and blockchain enthusiasts were brought together by a shared vision for the future, focusing on decentralization and cryptography instead of more traditional financial means.

    Because of this, there are strong ideological forces in much of the blockchain community, which sways frequently into the realms of libertarianism and anarchism.

    Companies need to respect these attitudes if they want to attract the best people for their positions. They also need to realize that this makes certain projects much easier to get off the ground than others. A crypto-anarchist might be far more interested in a project that aims to bring about improvements to democracy in the developing world, than a project that aims at cutting costs in the banking sector.

    In saying this, most great developers are far from tinfoil hat-wearing crazies. The blockchain community is a broad church, with its fair share of conservatives and techno-capitalists as well. There are many excellent blockchain developers who see the technology purely for its usefulness and have developed their skills in order to make money or to help advance our society.

    The important thing for a business looking to hiring a blockchain developer is that they hire someone with a background that fits in with their company culture and goals. The wrong kind of developer can result in an unproductive working relationship.

    If you want to find a good developer, you need to look for them in their natural habitat. The blockchain community is tightknit, and many of the best developers and thought leaders are constantly engaging with each other to keep up on the latest projects and news.

    These meeting places are where the astute hiring manager should look for them, whether they are online discussion groups or job board like on Blockgeeks, or real life meeting places, such as conferences. Once you have uncovered their hiding place, you will discover blockchain developers scurrying around between projects like beetles.

    What you have to keep in mind is that they are in demand. They are highly skilled and have many other recruiters chasing them with sweet deals. The ball is in their court. Your first option is to grovel, beg and plead for them to work with you, but this might not always work.

    As was mentioned above, blockchain developers are often a very different kind of worker, with unique skills, habits, and lifestyles. You need to find out how you can tempt them into working with you. Unless they got into bitcoin in the very early days and are now comfortable millionaires, money will be one of the biggest motivating factors.

    The best developers are commanding a high fee, and if you want a highly skilled person, you need to be willing to match what your competitors are offering.

    Unless you are in a major cosmopolitan city, you may also need to cast your net wider, because the right talent might not be close by. Your company should consider whether the position can be filled by a remote worker and come up with ways on how to accommodate them into your operations. Blockchain developers may also want to set their own schedule, have more frequent holidays and have access to other special privileges.

    To get more comfortable with Truffle, you can try this step-by-step guide to learn how to build your first blockchain app with Truffle. Follow this nice tutorial from Loom to build a game using Solidity. You will make an army of zombies and then fight a war on the blockchain.

    All of this will be done with Solidity, so by the end of the tutorial you will become pretty experienced with this language. Also, this tutorial will allow you to see that blockchain and smart contracts are useful not only for payments, but for game development as well. Maybe that will help you think outside the box and come up with your own ideas about blockchain game development. The code for smart contracts written in Solidity is only a tiny part of the overall codebase for a DApp.

    Your coding skills in other languages are far more important for that job. Though Ethereum is probably the most popular platform so far, it would be beneficial to get some experience with other platforms as well. Your best bet would be Hyperledger or Multichain. DApps consist of two parts — a front-end part and a back-end part. Front end development is similar to the development of a website or a mobile app.

    Back end development is a bit more tricky. It requires a good knowledge of cryptography as the blockchain platform relies on cryptographic functions to identify users.

    As a blockchain developer, you will need to be comfortable with different data structures like Stack, Queue, Linked List, Tree, and HashMaps. Bitcoin is open source, so you can contribute to the project at any stage. If you actually end up contributing to Bitcoin, it will give you credentials to work on almost any other project in the blockchain industry. Giovanni Casinelli, the founder and owner of a blockchain jobs site CryptoJobs.

    A deep understanding of distributed ledger protocols is among the most desired skills for blockchain developers. So learn about it if you want to get a job in the industry. If you are not sure where to start, you can consult the learning resources list curated by CryptoJobs. After acquiring the relevant skills, try to build your own application to get hands-on experience with blockchain development.

    The application should showcase your understanding of the blockchain. It can be something like a decentralized voting system, and Ethereum has a pretty useful guide on building such an app. Below you will find a comprehensive list of resources for learning Ethereum compiled by Xanesghost , an active contributor to blockchain-related threads on Reddit. It is possible to find a job in the blockchain industry in specialized startups or big tech firms. The most common options: startups, tech firms, banks, private sector firms, government services, professional services firms e.

    As the blockchain industry is booming, specialized job sites that aggregate vacancies in the blockchain emerge. One of them is BlockchainJobz , which currently has more than 1, open positions advertised. It will certainly be easier for you to land a job in the blockchain if you have relevant experience.

    Try contributing to open-source projects for starters. If you have years of experience in web development, it would be worthwhile to get some blockchain-related certifications to increase your chances of finding a job in the industry. You can get certified in Hyperledger Platform, for instance.

    The Gitcoin project aims to push open source forward by attaching bounties in Ether for solving GitHub issues. All you have to do is solve a problem on GitHub, and if the bounty submitter approves it, you will be paid in Ether via smart contract.

    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. 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.

    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. To read more about this process, check our guide on What Is Cryptocurrency Mining. Blockchain technology looks to resolve these issues.

    However, there are still multiple vulnerabilities in codes that can be breached by sophisticated hackers. The responsibility of a dedicated blockchain developer will depend on the involvement of the company you work for. One of the key roles blockchain developers will be responsible for is to update and maintain security measures within a blockchain, private clients in the case of freelancers or the company you work for.

    If you work for a company that is developing its own ICO , you will need an in-depth knowledge of algorithms to design advanced security codes that are impregnable. A solid understanding of coding is imperative for top-level blockchain developers.

    Blockchain developers will also be tasked with managing online resources about the demands of the network. You will have to know how to handle remote and local queries which require an in-depth understanding of how the blockchain you are operating with functions.

    If you are designing an ICO, you will need to figure out how the technology can function in the real world and provide benefits to end-users. Not only that, but you will have to develop a cryptocurrency that outperforms your rivals otherwise you will soon be out of a job. Blockchain developers that are working for companies that mine cryptocurrencies are responsible for creating a hash. Every block that is sealed is rewarded with a set amount of the currency you are mining.

    The actual amount will change over time and is different from one coin to the next. A hash is generated using SHA-2 which are a mathematical operations run on digital data. The goal of a blockchain developer is to work out the algorithm that seals the blockchain. Major corporations in multiple industries including finance, retail and technology are crying out for qualified engineers; there is a significant uptick in job openings.

    According to Upwork, blockchain development is the 2nd fastest growing industry right now, and as cryptocurrencies filter into the mainstream, there will be an even more significant demand for technologists. As a result, courses for blockchain engineering have been added to the curriculum of tech-oriented Universities including Cornell, Cambridge and Stanford. Graduates that already have a university degree in computer science or computer engineering are well placed to apply for jobs in the crypto-space.

    Experience as a back-end developer is obviously a crucial factor, and a solid understanding of code is vital. Blockchain developers also need to know the fundamentals of cryptography while knowledge of machine learning is a plus. Developers with experience will probably not feel like blockchain technology is new ground for them. Developers that do not have the time, finances or inclination to attend a university, should look into online blockchain development courses.

    There are plenty on offer, and although they will not be as comprehensive as a course with a leading university, online courses are far less expensive and — with dedication — quicker to develop the skills you need. Blockchain technology is not a single skill set that requires every developer to perform the same roles.

    The technology itself is a stack, and there are a variety of roles related to blockchain engineering. Experienced developers can demand an attractive salary for creating and running distributed ledgers although these roles are not in abundance. This is a good way for many aspiring engineers to earn while you learn and gain valuable experience to put on your CV. Entry-level qualifications are a strong background in software development and a basic understanding of blockchain principles.

    Experience in networking and security is desirable, but an awareness of modern technology tools and microservice architecture will leverage your opportunities of landing a job. A quick job search on Google will bring up multiple jobs for blockchain development roles.

    To increase your prospects sign up with job sites that specialise in IT and technology jobs, but in particularly blockchain like these below:. If you want to know more about how to become a blockchain developer, hit the blockchain forums and ask the community of developers that have firsthand experience.

    At the very least, they will be able to point you in the right direction — but you never know, you may even find an opportunity to work with a freelance blockchain developer that is willing to teach you the ropes.

    How to Hire a Good Blockchain Developer

    If the car was a rental car, GPS data could indicate when the driver went outside a geography covered by their rental agreement and charge a penalty. The challenge is that these sensors can be delivering data on a constant basis and it is not appropriate to send all of this data to a smart contract.

    A typical approach is to limit the number of messages sent to the blockchain while delivering all messages to a secondary store. For example, deliver messages received at only fixed interval, for example, once per hour, and when a contained value falls outside of an agreed upon range for a smart contract.

    Checking values that fall outside of tolerances, ensures that the data relevant to the contracts business logic is received and executed. Checking the value at the interval confirms that the sensor is still reporting. All data is sent to a secondary reporting store to enable broader reporting, analytics, and machine learning. For example, while getting sensor readings for GPS may not be required every minute for a smart contract, they could provide interesting data to be used in reports or mapping routes.

    On the Azure platform, integration with devices is typically done with IoT Hub. IoT Hub provides routing of messages based on content, and enables the type of functionality described previously.

    Many scenarios may require the need to incorporate attestable files. For multiple reasons, it is inappropriate to put files on a blockchain.

    Instead, a common approach is to perform a cryptographic hash for example, SHA against a file and share that hash on a distributed ledger. Performing the hash again at any future time should return the same result. If the file is modified, even if just one pixel is modified in an image, the hash returns a different value. To facilitate the ability for an external system or device to interact with the smart contract using either the REST or message API, the following must occur -.

    Once the application is uploaded, the Azure Active Directory account for the external system is assigned to the contract and the associated role. Integrating with external systems is a key requirement of many scenarios. It is desirable to be able to validate smart contract design prior or in parallel to the development of code to integrate with external systems.

    Specifically, the code integration with an external system may take a non-trivial amount of time. By using Azure AD and the auto-generation of UX by Azure Blockchain Workbench, you can allow developers to sign in to Blockchain Workbench as the external system and populate values from the external system via the UX.

    You can rapidly develop and validate ideas in a proof of concept environment before integration code is written for the external systems. Skip to main content. Contents Exit focus mode. Executing transactions occurs using the process depicted previously, where: The external application authenticates to the Azure Active Directory provisioned as part of the Azure Blockchain Workbench deployment.

    Authorized users receive a bearer token that can be sent with requests to the API. From here it is retrieved, signed, and sent to the appropriate distributed ledger. Querying occurs using the process depicted previously, where: The external application authenticates to the Azure Active Directory provisioned as part of the Azure Blockchain Workbench deployment. Messaging integration Messaging integration facilitates interaction with systems, services, and devices where an interactive sign-in is not possible or desirable.

    One-way event delivery from a smart contract to an event consumer In this scenario, an event occurs within a smart contract, for example, a state change or the execution of a specific type of transaction. This scenario occurs using the process depicted previously, where: The smart contract transitions to a new state and sends an event to the ledger.

    The ledger receives and delivers the event to Azure Blockchain Workbench. Azure Blockchain Workbench is subscribed to events from the ledger and receives the event. Azure Blockchain Workbench publishes the event to subscribers on the Event Grid. External systems are subscribed to the Event Grid, consume the message, and take the appropriate actions. One-way event delivery of a message from an external system to a smart contract There is also a scenario that flows from the opposite direction.

    Direct delivery of an Azure Blockchain Workbench in the expected format Some applications are built to integrate with Azure Blockchain Workbench and directly generates and send messages in the expected formats. This delivery occurs using the process depicted previously, where: An event occurs in an external system that triggers the creation of a message for Azure Blockchain Workbench. The external system has code written to create this message in a known format and sends it directly to the Service Bus.

    Azure Blockchain Workbench is subscribed to events from the Service Bus and retrieves the message. Azure Blockchain Workbench initiates a call to the ledger, sending data from the external system to a specific contract. Upon receipt of the message, the contract transitions to a new state. Delivery of a message in a format unknown to Azure Blockchain Workbench Some systems cannot be modified to deliver messages in the standard formats used by Azure Blockchain Workbench.

    This occurs using the process depicted previously, where: An event occurs in an external system that triggers the creation of a message.

    A Logic App or custom code is used to receive that message and transform it to a standard Azure Blockchain Workbench formatted message. The Logic App sends the transformed message directly to the Service Bus. Azure Blockchain Workbench initiates a call to the ledger, sending data from the external system to a specific function on the contract. Transitioning control to an external process and await completion There are scenarios where a smart contract must stop internal execution and hand off to an external process.

    Transition to the external process This pattern is typically implemented using the following approach: The smart contract transitions to a specific state. In this state, either no or a limited number of functions can be executed until an external system takes a desired action.

    The change of state is surfaced as an event to a downstream consumer. The downstream consumer receives the event and triggers external code execution.

    Return of control from the smart contract Depending on the ability to customize the external system, it may or may not be able to deliver messages in one of the standard formats that Azure Blockchain Workbench expects. Direct delivery of an Azure Blockchain Workbench in the expected format In this model, the communication to the contract and subsequent state change occurs following the previous process where - Upon reaching the completion or a specific milestone in the external code execution, an event is sent to the Service Bus connected to Azure Blockchain Workbench.

    Delivery of a message in a format unknown to Azure Blockchain Workbench In this model where a message in a standard format cannot be sent directly, the communication to the contract and subsequent state change occurs following the previous process where: Upon reaching the completion or a specific milestone in the external code execution, an event is sent to the Service Bus connected to Azure Blockchain Workbench.

    IoT integration A common integration scenario is the inclusion of telemetry data retrieved from sensors in a smart contract. The process depicts a pattern: A device communicates directly or via a field gateway to IoT Hub. IoT Hub receives the messages and evaluates the messages against routes established that check the content of the message, for example.

    Does the sensor report a temperature greater than 50 degrees? The Logic App or other code retrieves and transform the message to a known format.

    The transformed message, now in a standard format, is sent to the Service Bus for Azure Blockchain Workbench. This is because blockchain technology was an outsider interest that has only just begun to have a real commercial impact in the last couple of years.

    The result of this is that the best and most experienced developers tend to be in it for the passion, while other strong candidates are entering the industry because they see great opportunities in blockchain technology.

    If you are lucky, your project might be exactly what some blockchain developers are looking to work on. If this is the case, it should be relatively easy to entice them into your office. If not, you will need to figure out other ways to encourage them to contribute to your company. This can include giving them more autonomy and the freedom to pursue projects of their own. Other sweeteners can include opportunities for them to progress their career, such as further education and sending them to conferences.

    They are in such high demand that you really need to look after your developers if you want to keep them. This includes offering them a pleasant work environment, pay rises in-line with the market and the possibility for career progression.

    If you are reading this article, the chances are that you are already incredibly frustrated in your search for a blockchain developer. Unfortunately, like any skill that is in demand, it is not easy to find the right person, and you may have to offer more to entice them.

    The job market is struggling to keep up with the sudden demand for blockchain developers. Some universities and private companies have responded by offering a range of blockchain related courses in an attempt to meet the needs of industry.

    Courses vary from massive open online courses MOOCs , to traditional university lectures, as well as privately run boot camps that aim to quickly get students up to speed. MIT, Stanford, and Princeton all offer courses, with topics ranging from blockchain fundamentals to smart contracts and even how to develop apps on the blockchain. IBM also have courses on how to create private blockchain networks on Bluemix as well as how to add code for Smart Contracts.

    Sometimes they get five job offers a day. As a leader in the blockchain community, Blockgeeks have organized our own courses to help people gain a greater understanding of the technology and prime them for excellent opportunities in the job market.

    How To Become A Blockchain Developer

    But while the bulk of blockchain developers have a social conscious to serve the public, there is a chance the banks will not be able to manipulate the financial system the way they do with fiat currencies.

    Although still in its infant stages, cryptocurrencies which blockchains are directly related to are emerging quickly, and the demand for developers with knowledge of blockchain technology is at a premium. If you have designs to become an engineer in the crypto space you need to get to grips with how blockchain works.

    The blockchain is essentially a public ledger stored on the internet. It is comparable to a digital database that records transactions made by digital assets and cannot be changed or corrupted. There are mostly three principal technologies that create a blockchain:. The vision of Satoshi Nakamoto and the bulk of the blockchain community is to create a decentralised system that is both public for regulation and private for privacy.

    However, now financial institutions are pressuring government lawmakers to introduce laws and regulations, there is no telling whether blockchains will be a decentralised system as we move forward. And this is potentially where blockchain freelancers that understand the technology from the ground up can be most influential. Regardless of whether blockchain will be centralised or decentralised, the overriding goal is to ensure the technology creates a secure financial platform and a private digital identity for users.

    The keys, if stored sensibly in a hardware wallet , also protect owners from having their cryptocurrency stolen by cybercriminals. Its purpose is to ensure access is only permitted to owners.

    Another benefit blockchain technology is eliminating finance-related fraud and protect consumers from inadequate services or scams although there are plenty of Bitcoin scams too. Some of the most obvious provisions include smart contracts which protect the rights of buyers, and public ledgers eliminate tax avoidance scandals international corporations like Google, Starbucks and Amazon are notorious for.

    Every time validation is performed, miners have to create a block by sealing transactions with a hash. This is accomplished by running sophisticated algorithms to work out a random and incorruptible sequence of numbers, letters and symbols.

    Once the block is sealed and added to the previous block — hence the term blockchain — the record cannot be altered. To read more about this process, check our guide on What Is Cryptocurrency Mining.
