    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. Hyperledger is an open source collaborative platform that was created to develop cross-industry blockchain technologies. Here are some courses and other resources that'll help make you an industry-ready blockchain developer. What does a blockchain developer really do?

    It doesn't involve building a blockchain from scratch. Depending on the organization you work for, here are some of the categories that blockchain developers fall under. This type of developer is required to know a smart-contract language like Solidity, Python, or Go.

    Their main roles include:. There's a wide base of knowledge to help you become a blockchain developer. If you're interested in joining the field, it's an opportunity for you to make a difference by pioneering the next wave of tech innovations. It pays very well and is in high demand. There's also a wide community you can join to help you gain entry as an actual developer, including Ethereum Stack Exchange and meetup events around the world. The banking sector, the insurance industry, governments, and retail industries are some of the sectors where blockchain developers can work.

    If you're willing to work for it, being a blockchain developer is an excellent career choice. Currently, the need outpaces available talent by far. A few days ago I started learning blockchain development at BitDegree. Really recommend this platform if you are a beginner just like me. What it takes to become a blockchain developer What it takes to become a blockchain developer. Here's how to get started. Image by :. Get the highlights in your inbox every week.

    Technical fundamentals 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.

    Data structures The complexity of blockchain requires a solid understanding of data structures. Cryptography Cryptography is the foundation of blockchain; it is what makes cryptocurrencies work.

    Networking and distributed systems Build a good foundation in understanding how distributed ledgers work. Cryptonomics We've covered some of the most important technical bits. Decentralized applications Decentralized applications DApps are software built on blockchains. Here are some of them: Ethereum Ethereum is Vitalik Buterin's brainchild. One thing that makes Solidity unique is that it is smart-contract oriented. EOS EOS blockchain aims to be a decentralized operating system that can support industrial-scale applications.

Blockchain software is the hot topic right now. You know they should be able to tell which solutions to use in a specific business context. But it was complicated. If you needed a loaf of bread, but the baker required a new tool that you were not able to deliver, what then?

    As economies grew, this approach quickly became extremely ineffective. Money changed everything, allowing us to extract the value of a product and put it into a material that is hard to produce but easy to exchange. Now, you can buy a loaf of bread even if you do not have anything that a baker needs—you simply transfer value using currency. If you want to use money, you need to agree on the specific type or types of money that are accepted by enough people to run an economy efficiently.

    And who had enough power to impose precisely one sort of money on many people? In the past, coinage was approved by a king or queen, who guaranteed that you could use the currency in the land they ruled—everyone was forced to accept it. Monarchies in many places transformed into other systems of government, and in the meantime, banks were born.

    Still, this classical approach needs a central authority producing the means of payment. In the early s, Satoshi Nakamoto wanted to create a currency that could be signed without any central authority. One issue to solve was how to decide if a transaction happened and in which order it occured in the timeline. This problem, known as distributed consensus , cannot be solved in all cases.

    But a digital currency is just one particular case, and Nakamoto was able to solve it. When we create a currency, we need to have a way to know who is the current owner of a coin and also the history of its movement. Banks have historically tracked such details using a ledger. Bitcoin is a digital, distributed ledger where everyone can verify all coin operations. If we want to use such a distributed ledger, there are some issues to solve: Who can make an entry in this book?

    Supposing just anyone is allowed, how we can prevent someone from cheating by using the same coin for two different operations at the same time? This latter problem is called double spending and also is solved by bitcoin. To be accepted by the network, there are some conditions. Every transaction needs to be put into a block, and a node needs to use its computing power to solve a related mathematical puzzle, called its proof of work. When a block is transmitted, each node that receives it can decide to append this block onto its most extended chain.

    This is the default behavior in bitcoin, which guarantees that we can achieve consensus. Then the node can start mining a new block linking to this latest addition as its previous block. We can say that a transaction is accepted when a specific number of nodes have added this block onto their chains.

    Now that you have an overview of blockchain technology, here are some questions every blockchain application developer should be able to answer clearly in an interview. A blockchain is a distributed data structure, in the form of growing list of records—although it can also be represented as a tree—where every node is connected with another by cryptography. Block data contains all operations not yet included in another mined blocks.

    They have to have been accepted by a miner, verifying that the transactions do not break any conditions or rules of the network.

    In most cases, there is an upper limit to the amount of data that can be included in a single block. Mining is the process of adding new blocks onto the blockchain in proof-of-work systems. What is the difference between permissionless and permissioned blockchains? In a permissionless blockchain, everyone can join and become the part of the consensus process.

    Any popular public blockchain can be seen as permissionless. In a permissioned one, there is an additional authorization layer, which is used to control which nodes have access to which part of the blockchain; e. There are some solutions which can be seen as hybrid approaches.

    For example, J. The genesis block is the first block of any blockchain. It is the only block which does not contain a hash referring to a previous block.

    In many practical solutions, this block is itself hardcoded in software. It is a difficult computer science problem without a general solution, having been solved only for specific use cases, like bitcoin.

    A cryptocurrency is a digital asset that could be used as a replacement for existing fiat currencies.

    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.
