How To Become a Blockchain Developer: A Step-by-Step Guide
Thinking, h ow to become a blockchain developer , to start this journey, you should first learn the necessary blockchain developer skills you must have. Today blockchain applications transforming the world of technology. Blockchain developers handle the entire life cycle of a blockchain application. They create the architecture of the system, make smart contracts, and optimize the protocols. There are other professionals, too, who help a blockchain developer in their tasks, such as a blockchain engineer.
They both are involved in blockchain development but have different responsibilities. Blockchain software developers build applications based on blockchain architecture and protocol. Their apps run on the blockchain too. You can compare them with web developers, who use the products of a web architect protocol and design to develop web applications. Blockchain software developers create Dapps or decentralized applications.
They are responsible for the front-end as well as back-end development of Dapps. They also supervise the stack that runs the Dapps. These developers focus on the architecture development of a blockchain system. They design their consensus protocol and make most of the vital decisions related to blockchain.
They supervise the network and design the architecture of the same. Core blockchain developers are responsible for the security of their blockchain network as well. To handle those responsibilities well, they need to possess a few skills as well. Here are the primary blockchain developer skills you should have to become one:. Cryptography is the study of protocols that prevent unwanted parties from accessing your data. For example, public-key cryptography is a crucial topic of blockchain.
It forms the basis for the transactions we make through cryptocurrencies. Save transactions of cryptocurrencies take place through encryption and decryption of public and private keys. Another essential concept of Cryptography is cryptographic hashing.
Hashing refers to producing an output of a specific length from an input of any length. Certainly, cryptography is vital for the proper workings of blockchain technology. Since the day Ethereum entered the market, smart contracts have become a popular term in the blockchain industry.
Almost every blockchain solution wants to use smart contracts for their benefit. So you can see how powerful this technology is.
Smart contracts let two parties exchange goods or services without needing an intermediary. You can compare smart contracts with a vending machine. You put in the payment, choose the product you want, get the product along with the remaining change. Smart contracts finish only when the involved parties fulfill both of their conditions.
You can use smart contracts in many areas of different industries, such as law, construction, and many others. It can remove the middlemen from contracts and help in saving money and resources.
To become a blockchain developer, you should make yourself familiar with smart contracts. It is one of the essential blockchain developer skills. Multiple languages specifically focus on smart contract development, such as Chaincode and Viper. The entire blockchain network is made up of data structures, as even a block is a type of data structure.
A block clusters transactions for the public ledger because so it is a container data structure, whereas the public ledger is the blockchain. A block also contains a header, and the former is around 10,x larger than the latter.
If you're a Java developer who has done your background study by reading the books I recommend above and are ready to get your hands dirty, start with one of the following popular open source blockchain projects written in Java:. If you're ready to get started with blockchain, go to GitHub and play with one of the projects listed above. The rest will follow. The future is open and decentralized.

It was specifically created to attract developers from the Java ecosystem into the blockchain world. If you prefer to start with Bitcoin directly, this is the Java project to explore.
It is a very well documented and active project that makes talking to Ethereum-compatible nodes straightforward. I created an Apache Camel connector for it, which you can read about. FundRequest is an end-user application written in Java. While the above projects are examples of clients or nodes, FundRequest is an open source funding platform implemented on top of the Ethereum network and fully written in Java.
It is a good example of how you can implement a complete blockchain-based project and interact with the Ethereum network.
If you want to know about blockchain, learning Bitcoin and Ethereum is akin to taking networking, database theory, messaging, data structures, and programing language classes during your university studies. Understanding how these two blockchain technologies function will open your mind to the blockchain universe.
Before you try to do any work with blockchain technology, I recommend learning the technical basics of Bitcoin and Ethereum. Ultimately, blockchain is a new combination of existing technologies with human behavior fueled by network effects. If you are coming from a technical background, it makes sense to build on your existing knowledge and see what blockchain brings to the table.

It was specifically created to attract developers from the Java ecosystem into the blockchain world. What is it? Well, Blockchain is literally a chain of blocks as the name suggests!
Each of these blocks contains a cryptographic hash function linking to the previous block, a timestamp , and the digital information in the block. These blocks are structured in such a way that it is very difficult to modify the data and so they ensure transparency while simultaneously maintaining security.
Blockchain is actually synonymous with security as tampering with these blocks is next to impossible! And that makes this technology very popular in fields like banking, finance, etc. In fact, Blockchain was first made popular when it was used in the implementation of the BitCoin. After all, people want their money to be as secure as possible! And so currently, Blockchain developers are highly in demand. Python is fast becoming the most popular programming language in the world and if you are a new developer experience in Python, then it might be the best Blockchain language for you.
A problem with Python is that it is an interpreted language and that creates some problems for complex cryptographic operations in Blockchain. However, Python is an object-oriented language which helps in managing many of its performance-related overheads. Another benefit of Python is that developers can prototype their ideas quickly with any long-winded coding required. Python also has huge opensource support which makes it ideal for Blockchain.
There are many Python libraries, plugins, and other resources available online for almost every problem you can encounter in Blockchain development. This is true in Blockchain technology as well! This is useful for constructing applications without necessarily knowing their inside implementations. Also, the one property of Java that is particularly useful in Blockchain is its portability. These programs are not dependent on system-specific architecture as they use the universal JVM Java Virtual Machine for execution.
This portability along with the other popular features of Java makes it perfect for Blockchain. Solidity is one of the fastest-growing blockchain programming languages that was created for writing smart contracts that run on the Ethereum Virtual Machine EVM. It was developed by Ethereum which is a blockchain-based distributed computing platform and operating system.
Since Solidity is created keeping Blockchain in mind, it is suited to solving many of the problems faced by Blockchain developers. Solidity is developed similar to the ECMAScript syntax but it has features like variadic return types, static typing, etc.
So it is a great language to learn if you want to focus specifically on Blockchain development in depth. Vyper is a new Blockchain programming language that is derived from Python 3. Vyper is created as an alternative to Solidity. However, Vyper has different control structures than Solidity and it also handles security issues differently. Vyper has also don away with much of the OOPS functionalities in Solidity along with other features like infinite loops, modifiers, recursive calling, etc.
This helps in avoiding the security issues that arise because of these features. So if you want a Blockchain development language for writing smart contracts, check out Vyper!
Go is a great programming language for building fast and efficient Blockchain systems. It is the best language for creating hyper ledger fabric, which is a foundation for developing applications for Blockchain.

The main goal of Hyperledger is to develop technologies learn the cross-industry Blockchain using an open-source collaborative platform. There can been a massive development in can field of Blockchain technology in the java decade. Before you try to do any work with blockchain technology, I recommend learning the technical basics of Bitcoin and Developer. The other vital aspects that you need to take care of include the consensus protocol design and making high-level decisions. Well, Blockchain is literally a chain of blocks as the name suggests! Most other blockchain projects, learn they are public or developer, permissionless or permissioned, are forks of Bitcoin java Ethereum, or build and improve blockchain shortcomings in some ways by blockchain certain trade-offs.
They can be used for lots of different things. Data Science. Related Learn Here is a list of related courses:. Our Java-based blockchain was kept developer deliberately and so, from a users can of view, it only has blockchain functions of sending java and viewing them in the blockchain, quite similar to a public chatroom. Solidity is one of the fastest-growing blockchain programming languages that was created for writing smart contracts that run on the Ethereum Virtual Machine EVM, can java developer learn blockchain. It would look something like this:.
Master The Technology of the Future - Blockchain
Solidity is a high-level coding language. This means that it is designed to be read and used by human beings! Computer programs are usually written in a high-level language and then translated into a low-level coding language.
Now, if you really want to know how to become a blockchain developer, you must learn about low-level coding languages also. A low-level coding language is designed to be read and used by computers. Low-level languages are made up of 1s and 0s. This is called binary. When a blockchain developer builds dApps and smart contracts on the Ethereum blockchain, there are rules which guide their design.
For example, if you want to design a new cryptocurrency using Solidity you have to follow a set of rules called ERC These rules make it easier to tell how new dApps will work when they are launched on the blockchain. Ethereum blockchain development happens in a very special place called the Ethereum Virtual Machine.
A virtual machine is an environment where new computer programs can be written. You would build and test your car in a factory and on empty streets. This is how the EVM works. It is a factory for building new smart contracts. This makes Ethereum a great place to learn blockchain. The EVM allows users to practice blockchain programming without worrying about making mistakes. The EVM is also Turing complete. This means that whatever a computer can do, you can design using the EVM. The only limit is your imagination!
Think of all the exciting new ideas being built using the EVM right now! Learning Solidity is a lot like learning to speak a new language , but it is essential to become a blockchain developer on the Ethereum platform. Solidity basics are like nouns, adjectives, and verbs. Nouns, adjectives, and verbs are tools for creating sentences. Here are some of the tools for creating Solidity smart contracts;.
Variables - These are used to store information on the blockchain. There are lots of different kinds of variables but here are some of the most common:. Booleans - These are used to store information that is either true or false. The keyword for Booleans is bool. Integers - These are used to store information as a number.
There are two types of the integer. Regular integers can be positive or negative numbers. Their keyword is int. Unsigned integers can only be positive numbers. Their keyword is uint. Addresses - These are used to store Ethereum addresses. Each Ethereum user has its address or addresses on the blockchain.
Diana and Ross, from the example earlier, would both need addresses for their smart contract to work. Strings - These are used to store text information. Their keyword is strings. Functions - A function is used to do a certain job.
A function can use information from variables to create new information. For this sum, the keyword would be function add. This is what sums look like in smart contracts;. Structs - These are used to put variables into groups. Do you remember that new car you were building? In Solidity, you could use a struct to group information about your car! It would look something like this:. Not only are there basic courses, but also game-courses that could teach you! Two courses that teach you how to become a blockchain developer are Space Doggos and CryptoZombies.
Space Doggos and CryptoZombies are both gamified Solidity lessons for beginners. This means that they both turn Ethereum blockchain into a game! Space Doggos allows beginners to learn blockchain development by creating characters and environments for an adventure in space.
The first lesson contains ten chapters of information and tasks to get you started. Each chapter has detailed notes on the processes being used. These include the variables, functions, and structs I talked about earlier. Users can design their astronaut dog using real Solidity code. The code becomes more complicated as the adventure continues.
As an introduction to the Ethereum blockchain, Space Doggos is a well-designed and entertaining platform for any upcoming blockchain developer. CryptoZombies allows users to design a whole army of zombies. To do this, users first have to build a zombie factory.
Then, users can code the way their zombies look and even the way they attack their victims! CryptoZombies is very entertaining and makes a lot of difficult ideas fun.
So, if you want to command an army of the undead, then CryptoZombies is the course for you. However, I would recommend Space Doggos. For this, I would recommend the BitDegree Solidity course. The BitDegree Solidity course is great for users who have learned Solidity basics and are ready to start blockchain programming. The course starts with the environment setup and takes users through to building and launching their cryptocurrency!
We've covered the topic quite in-depth, but if you're more of a TL;DR kind of a person, let's see the shorter version of the steps you should take if you want to master blockchain developing:.
Now, you know where to start. You know how to become a blockchain developer. When these particular situations or conditions are met, then the transaction will be automatically processed when required.
Currently, Auditing and optimizing of smart contracts cannot be done by many developers. A developer should be very well aware of all possibilities of execution of a smart contract. He should be able to ensure that smart contracts are only executed when it is expected.
There are some decentralized applications DApp that are built on blockchains. There are various platforms for a blockchain developer to build a DApp. Here are some of the popular Decentralized Applications:.
The main goal of Hyperledger is to develop technologies in the cross-industry Blockchain using an open-source collaborative platform. The main goal of the EOS blockchain is to support industrial-scale applications. It is a decentralized operating system that has more scalability and higher transaction speed such as Ethereum.
NEO is not limited to one language, unlike Ethereum. It will work as a platform for digital businesses in the future. In , Vitalik Buterin created Ethereum, which is currently the most popular platform for development.
The Ethereum is fueled by the cryptocurrency called Ether. The language used in the Ethereum is called Solidity. Solidity is a smart-contract oriented language. A blockchain developer should be able to innovate using the design thinking methodology. Blockchain is used to simplify the processes in the business, which helps in driving outcomes of companies.
A developer in Blockchain should have security skills like elliptic curve digital signatures, Merkle proofs, cryptographic hashing, private key, and public-key cryptography and many more.
Frameworks in security are getting evolved for regulatory needs, legal needs, and compliance needs. There are multiple frameworks in Blockchain and learning all of them can create confusion. One should know how to select the right blockchain platform for particular cases.
Different blockchain platforms such as R3 Corda, Ripple, Ethereum, Hyperledger Fabric are some of the excellent blockchain platforms that a beginner can start to learn about. A developer should be an expert to build distributed ledger technology.
It will help in accelerating the development of smart contracts. The mindset of blockchain developers should be open source because there is a risk of deployment in various technology platforms of interconnecting ledgers. Business outcomes can be driven, and latency is reduced by integrating with systems of an enterprise. With a strong fundamental and practical understanding of cryptocurrency, it is now time to dive deep into coding. For beginners, we recommend learning Solidity.
It will help you create and developer dApps and smart contracts on Ethereum blockchain. You may also want to dive deep into the open-source code of different blockchain platforms.
Most of the blockchain platforms or solutions are open source, and hence the code is readily available for scrutiny or learning. However, creating or maintaining an open-source blockchain is not easy.
It requires you to overcome challenges such as security, performance, resource management, and isolation. If you do everything correct, you will have a basic working blockchain! Smart contract is also one of the vital blockchain concepts that you need to learn. It is a computer protocol similar to legal contract in real life. You can use it to automate or add functionality to your dApps.
A smart contract needs to have three main features, including deterministic, terminable, and isolation. Keep reading blockchain-related content. Many websites offer high-quality, blockchain content. We recommend checking out BlockGeeks and Blockchains.
