Companies such as IBM and Samsung are at the forefront of blockchain as the underlying infrastructure for the next wave of tech innovation. There is no doubt that blockchain's role will grow in the years to come. Thus, it's no surprise that there's a high demand for blockchain developers. The freelancing site Upwork also released a report showing that blockchain was one of the fastest growing skills out of more than 5, in its index.
Describing the internet in , Jeff Bezos said , "we are at the Hurley washing machine stage. The industry is busy building its foundation. If you've been considering a career as a blockchain developer, the time to get your foot in the door is now.
However, you may not know where to start. It can be frustrating to go through countless blog posts and white papers or messy Slack channels when trying to find your footing.
This article is a report on what I learned when contemplating whether I should become a blockchain developer. I'll approach it from the basics, with resources for each topic you need to master to be industry-ready. Although you're won't be expected to build a blockchain from scratch, you need to be skilled enough to handle the duties of blockchain development.
A bachelor's degree in computer science or information security is required. You also need to have some fundamentals in data structures, cryptography, and networking and distributed systems. The complexity of blockchain requires a solid understanding of data structures.
At the core, a distributed ledger is like a network of replicated databases, only it stores information in blocks rather than tables. The blocks are also cryptographically secured to ensure their integrity every time a block is added. For this reason, you have to know how common data structures, such as binary search trees, hash maps, graphs, and linked lists, work.
It's even better if you can build them from scratch. This GitHub repository contains all information newbies need to learn data structures and algorithms. Cryptography is the foundation of blockchain; it is what makes cryptocurrencies work. The Bitcoin blockchain employs public-key cryptography to create digital signatures and hash functions.
You might be discouraged if you don't have a strong math background, but Stanford offers a free course that's perfect for newbies. You'll learn about authenticated encryption, message integrity, and block ciphers. And don't forget cryptographic hash functions.
They are the equations that enable most forms of encryptions on the internet. There's extensive use of cryptographic hash functions in blockchain. Build a good foundation in understanding how distributed ledgers work. Also understand how peer-to-peer networks work, which translates to a good foundation in computer networks, from networking topologies to routing.
In blockchain, the processing power is harnessed from connected computers. For seamless recording and interchange of information between these devices, you need to understand about Byzantine fault-tolerant consensus , which is a key security feature in blockchain. You don't need to know everything; an understanding of how distributed systems work is good enough. You can also consult this list of awesome material on distributed systems. We've covered some of the most important technical bits.
It's time to talk about the economics of this industry. Although cryptocurrencies don't have central banks to monitor the money supply or keep crypto companies in check, it's essential to understand the economic structures woven around them.
You'll need to understand game theory, the ideal mathematical framework for modeling scenarios in which conflicts of interest exist among involved parties.
It's lucid and well explained. You also need to understand what affects currency valuation and the various monetary policies that affect cryptocurrencies. Here are some books you can refer to:. Depending on how skilled you are, you won't need to go through all those materials. But once you're done, you'll understand the fundamentals of blockchain.
Then you can dive into the good stuff. Unlike traditional judicial systems, smart contracts are enforced automatically and impartially. There are also no middlemen, so you don't need a lawyer to oversee a transaction. As smart contracts get more complex, they become harder to secure.
You need to be aware of every possible way a smart contract can be executed and ensure that it does what is expected. At the moment, not many developers can properly optimize and audit smart contracts. Decentralized applications DApps are software built on blockchains.
As a blockchain developer, there are several platforms where you can build a DApp. Here are some of them:. Ethereum is Vitalik Buterin's brainchild. It went live in and is one of the most popular development platforms.
Ether is the cryptocurrency that fuels the Ethereum. If you've got any experience with either, you'll pick it up easily. It became NEO in Unlike Ethereum, it's not limited to one language. It's focused on providing platforms for future digital businesses. Consider NEO if you have applications that will need to process lots of transactions per second. However, it works closely with the Chinese government and follows Chinese business regulations. EOS blockchain aims to be a decentralized operating system that can support industrial-scale applications.
It's basically like Ethereum, but with faster transaction speeds and more scalable. The advent of Bitcoin and its underlying tech, Blockchain changed the world, particularly the Banking and Finance sectors. However, with Bitcoin, the scope of development is quite constrained. It took the Blockchain game to a whole new level, creating scope for developers around the world to build innovative applications on top of Ethereum. As a result, the craze for Blockchain tech only continued to escalate, thus, making Blockchain skills one of the hottest skills today!
But the most challenging part comes at the very beginning of the journey —. For a beginner, Blockchain is a complicated technology. While Blockchain and cryptocurrencies can bring you a lot of profit, first you must understand what you wish to accomplish with Blockchain tech.
So, you must ask yourself the following questions and find answers to them:. If you work as a Blockchain Developer for a reputed company, you can earn extremely high salary packages. This is because there is a significant shortage of adequately skilled Blockchain Developers. However, if you are an independent entrepreneur developing Blockchain applications, you can raise a lot of money for your projects via funding.
Answering these questions will help you understand what exactly you want out of your Blockchain career. Bitcoin is undoubtedly the most stable and widely used Blockchain tech for processing valuable transactions, but then it can handle only simple transactions. EOS too can run smart contracts. However, EOS is much more scalable than Ethereum, and unlike Ethereum, it allows for free transactions. While EOS may look like the best choice, remember that it is more scalable which leads to a centralization of sorts contrary to the decentralization feature of Blockchain.
Thus, the smart choice here is Ethereuem since it is highly programmable, supports Ethereum tokens, and is backed by an active community of talented developers. After choosing your focus of study Blockchain network , you should get familiar with Decentralized Apps or Dapps. More than 2, applications built on Ethereum for example, Marketplaces, Decentralized Exchanges, and Gambling Dapps already exist. So, you can get a headstart there.
Is it a gaming Dapp or a decentralized exchange or something unique? Once you figure this out, you should figure out how you wish to develop your Dapp. For developing a Dapp, you must learn how:. To successfully write smart contracts and develop Dapps, you must learn to use the following development tools:.
Truffle is written in Nodejs and is backed by a strong community. The advantage of Web3 is that it can dynamically create abstractions objects to represent a smart contract.
It comes with its distinct Github repo. It allows you to run a command to trigger a local Ethereum node and get ten addresses pre-funded with Ether.

Most people resort to learning Solidity with CryptoZombies, a game designed to introduce and teach the fundamentals of Solidity by generating an army of Zombies in a smart contract. While this is an exciting way to learn Solidity, you should also be thorough with the official Solidity Documentation for it is the most comprehensive guide on Solidity.
It is updated regularly and will teach you the basics of Solidity, including the primary variable types, the main control structures, and the overall structure of a smart contract. Dapps allow users to interact with them seamlessly. Before building a Dapp, you must understand how it works. When you visit the Cryptokitties website, you land on the main user-interface — the frontend part looks just like a standard web app, and the backend is deployed on private servers.
Then begins the Blockchain layer with Metamask. The players use Metamask to transfer Ether to Cryptokitties. After this comes to the smart contract that stores all the game data.
Since the smart contract is deployed on the Ethereum network, it is hosted by multiple machines simultaneously. This is precisely the design of a Dapp. Then you have the browser extension here, Metamask , and then finally, you have the smart contracts. To successfully develop a Dapp, you must ensure that these three layers can communicate with one another seamlessly. There are various articles, videos, and ebooks that teach you how to build a Dapp from scratch.
