Each section will be purely introductory, as the topic can get pretty extensive and full of code.<\/span><\/p>\n<h3>1. C++<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-30835 size-medium\" src=\"https:\/\/simpleprogrammer.com\/wp-content\/uploads\/2018\/12\/c-300x209.png\" alt=\"blockchain programming\" width=\"300\" height=\"209\" \/><\/p>\n<p>Let\u2019s start with the oldest of them all, C++. The language came to life in 1985 through the efforts of Bjarne Stroustrup. By then, the rudimentary C language existed, but it was process-oriented; C++ cropped up as an upgraded extension that is object-oriented (where data and functions are bundled up into a package called \u201cObjects\u201d). For the complete freshman, an object-oriented product can be reused on other platforms without the need for fresh coding.<\/p>\n<p>C++ retained the efficiency, security, and flexibility of C. Its evergreen nature has made it the core language for blockchain coding, including the bitcoin blockchain. Warning to the newbies, though: As a type-only language with fairly outdated syntax, the learning curve is a bit steep. However, as most blockchain technologies are written in this language, any efforts you put in to learn this language will pay forth abundantly.<\/p>\n<p>Here are a few more reasons why C++ is preferred for blockchain coding:<\/p>\n<p><strong>Better memory control.<\/strong> There are a lot of demands in the blockchain ecosystem. For instance, the platform needs to be a secure fortress but at the same time execute transactions and interact with all the nodes at a faster speed. For all these to happen, you need to have better control over memory and CPU usage. C++ can offer you that.<\/p>\n<p><strong>Superb multithreading.<\/strong> Threads are a bundle of instructions that are to be executed at the same time. During blockchain development, you will come across tasks that parallelize and those that do not. Most languages can only handle one of these tasks and not both. Guess what, C++ allows you to handle both simultaneously.<\/p>\n<p><strong>Compile time polymorphism.<\/strong> As was said before, C++ is an object-oriented programming (OOP) language. It also happens that polymorphism (using a certain feature in several ways) is a property of OOP. Now, by coding your blockchain through C++, you will be able to execute some tasks separately, thus enhancing the performance of the entire digital ledger.<\/p>\n<p><strong>Code isolation.<\/strong> This archaic but revolutionary coding language has namespace features that can be shipped from one place to another. But at times, collisions can occur and distort the entire system. However, thanks to the language\u2019s segmentation ability that groups various APIs differently, code isolation\/separation can become a little easier.<\/p>\n<p><strong>Maturity.<\/strong> As one of the oldest coding languages, C++ is mature and gets updated on a regular basis. Besides that, the language sports practical features like debuggers and special analytical tools that can detect or optimize various functions. This complexity and up-to-dateness of the language may be some of the reasons why Satoshi used it for bitcoin\u2019s source code.<\/p>\n<h3>2. Python<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-30836 size-medium\" src=\"https:\/\/simpleprogrammer.com\/wp-content\/uploads\/2018\/12\/python-300x150.png\" alt=\"blockchain programming\" width=\"300\" height=\"150\" \/><\/p>\n<p>Python is another simple coding language for a beginner programmer who is afraid of C++\u2019s complex nature. It was developed in 1991 by a Dutch programmer by the name of Guido van Rossum. The language\u2019s structure is based on a simple premise: simplicity, readability, and minimalism.<\/p>\n<p>The simple nature of this language has seen it be supported by a massive crowd of both new and established developers. Rather than the curly brackets and keywords used in C++ to represent code blocks, Python uses simple and less-scary white spaces.<\/p>\n<p>Simplicity can be easily translated to mean inefficiency. However, Python is good enough to build complex digital ledgers that are stable and reliable. And here is the best part: This language is scripted and can be compiled and uncompiled. For instance, when you find a bug in your code, you just fix it and reload your application.<\/p>\n<p>For other languages like C++, you need to stop the app, fix the bug in your source code, and recompile it before restarting the application. It\u2019s quite a lot of work that can be avoided by choosing Python. Additionally, the language offers developers a vast, free resource center that they can use to write their blockchain code.<\/p>\n<h3>3. JavaScript<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-30837 size-medium\" src=\"https:\/\/simpleprogrammer.com\/wp-content\/uploads\/2018\/12\/javascript-300x188.png\" alt=\"blockchain programming\" width=\"300\" height=\"188\" \/><\/p>\n<p>JavaScript is one of the most-used languages on the World Wide Web. If you want an interactive site with beautiful UIs, this is the language to use. All the major browsers such as Google Chrome and Firefox support it.<\/p>\n<p>We already said that a blockchain is, roughly put, a system of blocks placed one after the other. However, there is something special about this ledger\u2014it\u2019s immutable, meaning once data has been written, there is no undoing. JavaScript is one of the go-to languages when making a simple but tamperproof blockchain that is impossible for hackers and other deceitful individuals to alter. Just one setback, though: The language lacks the SHA256 hash function.<\/p>\n<h3>4. Solidity<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-30931 alignright\" src=\"https:\/\/simpleprogrammer.com\/wp-content\/uploads\/2018\/12\/developer.png\" alt=\"\" width=\"280\" height=\"280\" \/>This is the most complex, high-level language that applies JavaScript\u2019s scripts and functions as well as C++\u2019s classes. The language is not only beginner-friendly but also offers tips and instructions on how to go about using its code. While the language is not very complicated, those who have a fair grasp of modern programming languages have an advantage.<\/p>\n<p>Even though Solidity is still trying to establish its footing in the coding world, Ethereum (the second-biggest cryptocurrency after bitcoin) is already using it. Well, they made the language, so it makes sense that they be the first ones to use it. Nevertheless, Ethereum blockchain is one of the most efficient when it comes to speed and ease of creating smart contracts.<\/p>\n<p>So if you are looking to create a decentralized app, hold an initial coin offering, or build a secure, immutable, and multipurpose blockchain, Solidity is the language to use. It&#8217;s a must-know language for anyone who wishes to integrate smart contracts in their digital ledger. For tutorials on Solidity, you can check out ConsenSys Academy or the languages\u2019 documentation from readthedocs.io.<\/p>\n<h3>5. GO<\/h3>\n<p>GO is the short form of GOLang, a relatively modern coding language that was developed in 2007 at Google and officially released for public use in 2012. This robust and multipurpose coding language was created in an effort to combine both the syntax and user-friendliness of other common languages like JavaScript while retaining the reliable security aspects of older languages like C and C++.<\/p>\n<p>GO inherently runs in an operating system, and this means maximum flexibility, especially when dealing with several parts of a blockchain simultaneously. Ethereum\u2019s SDK protocol is written in GO, and there are many other <a href=\"https:\/\/simpleprogrammer.com\/testing-blockchain-applications\/\" target=\"_blank\" rel=\"noopener\">blockchain applications<\/a> of this language.<\/p>\n<h2 id=\"use-cases\"><span style=\"font-weight: 400;\">9 Blockchain Use Cases You Can Work in as a Developer<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Every year, there\u2019s more <\/span><a href=\"https:\/\/www.ibm.com\/blockchain\/use-cases\/\"><span style=\"font-weight: 400;\">use cases for blockchain<\/span><\/a><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Applications are being developed for different industries:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Cybersecurity<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Healthcare<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Manufacturing<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Legal and Government<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Charity<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Retail<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Real Estate<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Tourism<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Media<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">and many others.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you become a blockchain developer, you can have your pick of which use case in all these industries you\u2019d like to work on.<\/span><\/p>\n<h2 id=\"how-to-code-blockchain\"><span style=\"font-weight: 400;\">How to Code Blockchain &#8211; Simplified in 5 Easy Steps<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">When you\u2019re a beginner, you might not know how the process of coding for blockchain will look for you.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Let\u2019s give you the easiest example for how to code blockchain.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Here\u2019s how it works, in a nutshell:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Code your smart contract or dApp inside your <\/span><a href=\"https:\/\/ethereum.org\/en\/developers\/docs\/ides\/\"><span style=\"font-weight: 400;\">IDE<\/span><\/a><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Test it on a <\/span><a href=\"https:\/\/medium.com\/datawallet-blog\/how-to-deploy-a-local-private-ethereum-blockchain-c2b497f068f4\"><span style=\"font-weight: 400;\">local blockchain<\/span><\/a><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Run or Connect to a <\/span><a href=\"https:\/\/www.coindesk.com\/learn\/what-is-a-node\/\"><span style=\"font-weight: 400;\">node<\/span><\/a><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Test it on a <\/span><a href=\"https:\/\/en.wikipedia.org\/wiki\/Testnet\"><span style=\"font-weight: 400;\">Testnet<\/span><\/a><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><a href=\"https:\/\/dev.to\/rounakbanik\/deploying-a-dapp-to-mainnet-3cob\"><span style=\"font-weight: 400;\">Deploy<\/span><\/a><span style=\"font-weight: 400;\"> it<\/span><\/li>\n<\/ol>\n<h2 id=\"what-you-need-for-blockchain-coding\"><span style=\"font-weight: 400;\">What do you need for blockchain programming?<\/span><\/h2>\n<h3><span style=\"font-weight: 400;\">Software<\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">an IDE (Integrated Development Environment) to compile, test and run your blockchain software.

Learn programming basics<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If you\u2019re not yet a developer, start with learning the basics of your first language. For different blockchain projects, you might need to learn different languages.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Always start with one, though. And you have to start somewhere, right?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">So, what language should you learn first?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example, you could start by learning to code with the node.JS platform (based on JavaScript).\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">JavaScript and Node.js are enough to build programs that interact with cryptocurrency APIs in real time. JavaScript is the most popular language for blockchain programming, while Solidity is the easiest to learn.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">You\u2019d be well-advised to learn both.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">2.

Understand consensus algorithms<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Consensus Mechanism: The instrument by which a decentralized system goes to an agreement on specific issues.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">E.g., the original consensus mechanism presented in the white paper, Proof of Work.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">6. Learn to fork an existing blockchain, like bitcoin or ETH<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">For this, you\u2019ll have to download and compile the core code on your computer. Then you\u2019ll reprogram the code to include the changes you want in your personal blockchain fork.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">7. Fork a wallet<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Learn how to create your own cryptocurrency <\/span><a href=\"https:\/\/blog.chain.link\/how-to-build-a-crypto-wallet\/\"><span style=\"font-weight: 400;\">wallet<\/span><\/a><span style=\"font-weight: 400;\"> from scratch.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">8.

Set up a testnet for that fork and put it online<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">A testnet is a blockchain which doesn\u2019t require you to spend real currency to use its network.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This makes them ideal for <a href=\"https:\/\/simpleprogrammer.com\/testing-blockchain-applications\/\">trying out your code ideas<\/a> or pre-launching a new tool you created. Getting started on a testnet can be a good sandbox exercise in your roadmap to become a blockchain developer.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">10. Write a smart contract and put it online at Ethereum or similar platforms<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Get your feet wet creating your first <\/span><a href=\"https:\/\/ethereum.org\/en\/developers\/docs\/smart-contracts\/\"><span style=\"font-weight: 400;\">smart contract<\/span><\/a><span style=\"font-weight: 400;\"> and putting it online.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">11. Code a dApp and put it online at a platform<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Now you\u2019re ready to develop your very own <\/span><a href=\"https:\/\/ethereum.org\/en\/developers\/docs\/dapps\/\"><span style=\"font-weight: 400;\">dApp<\/span><\/a><span style=\"font-weight: 400;\">, and release it to the world after you\u2019re finished.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">12. All the while, keep improving<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If you work hard at it, you can achieve all this in about three months.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">But while you\u2019re learning and getting your hands dirty coding your first projects on the blockchain, don\u2019t forget to mix with like-minded others:\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The best places for this are GitHub, Reddit and StackExchange.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Chat with other developers, ask questions and seek their help. You\u2019ll learn everything even quicker, you\u2019ll start getting your name out there, and you\u2019ll make some cool connections.<\/span><\/p>\n<h2 id=\"blockchain-money\"><span style=\"font-weight: 400;\">How You\u2019ll Make Mountains of Money as a Blockchain Developer<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The <\/span><a href=\"https:\/\/www.glassdoor.com\/Salaries\/blockchain-developer-salary-SRCH_KO0,20.htm\"><span style=\"font-weight: 400;\">salary<\/span><\/a><span style=\"font-weight: 400;\"> for a blockchain coder is quite high &#8211; usually over six figures per year.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As a freelancer, you can command hourly rates upwards of 100$ per hour.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">And if your own blockchain project takes off, it could be a way for you to get rich in a short amount of time.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">What is the salary of a blockchain developer?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">In North America, blockchain coders can make between $150-$200 per hour, or low-to-mid six figures per year. In Western Europe, developers can also make at least $100-$150. In the Far East, predominantly in India, you can find a blockchain developer for as little as $40 per hour.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">FAQ about Blockchain Programming for Beginners<\/span><\/h2>\n<h3><span style=\"font-weight: 400;\">Does a blockchain developer need coding?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">So far there aren\u2019t complete no-code solutions for working on blockchain technology, developing smart contracts or creating dApps. This means that you\u2019d need some amount of coding knowledge for any blockchain development project. For many applications, you can get away with specialized skills in only one or two programming languages.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Is blockchain programming difficult?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Blockchain programming can be more difficult, because you can\u2019t move as fast as in traditional development \u2013 you can\u2019t afford to break things in a decentralized database. Also, you need to be well-rounded in cryptography, back-end and front-end development and networking concepts.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">How long does it take to learn blockchain?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">You can learn blockchain programming to a decent level within 1-3 months if you follow the roadmap we outlined. To become an elite-level blockchain developer will take 1-3 years. Put in the time needed, and you\u2019ll be able to go far in this lucrative career.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Can you teach yourself blockchain?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">In theory you can learn blockchain by yourself. Teach yourself with free tutorials and a lot of coding practice. While many employers require a university degree, not all do. You also don\u2019t need to pay for a course. But it\u2019ll be easier if you don\u2019t do it all by yourself, but with expert instruction.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Enter the hottest developer career of the future:\u00a0 Blockchain programming.
