Heard that bitcoin value doubled again? or new cryptocurrency IPO’s are taking over the stock market! Well, cryptocurrency is just the tip of the iceberg. Blockchain technology is a lot more than just cryptocurrency and can revolutionize almost everything which surrounds us. You may refer to what is blockchain technology and how does it work for a more detailed explanation on this.
Blockchain finds its application in a lot of verticals including (but not limited to) healthcare, defense, cybersecurity, supply chain, manufacturing, etc. And it's due to this scope of applications that the demand for equivalent blockchain developers has skyrocketed. And while many designers, software developers & analysts are making their debut in the blockchain industry. There are many who feel lost. But don’t worry, in this post, I’ll be sharing with you the list of skills required to become a blockchain developer and would help you get hired. So, let's get started,
1. Blockchain Architecture
A blockchain developer should have an excellent understanding of blockchain, it's working, and its architecture. Concepts like cryptographic hash functions, consensus, distributed ledger technology are something you should have hands-on experience with.
2. Smart Contract Development
Smart Contracts will the most widely employed application in 2021 and beyond. The primary reason being the release of Ethereum 2.0. For beginners, understand that every blockchain tries to incorporate smart contract functionality into its system so that business logic can be easily applied on the blockchain layer. Hence, developers striving to get into the blockchain field should definitely learn about smart contract development, its importance and business application. This generally entails learning network-specific languages like Solidity, Viper, Chaincode, etc.
3. Data Structures
You need to learn data structures to become a blockchain developer. Why? Simply because blockchain developers work with various data structures regularly as they have to build networks and implement them.
The entire blockchain network is made up of data structures, as even a single block in the blockchain is nothing but a data structure in itself. These block clusters transactions for the public ledger and has a block size (generally 1 MB).
A block also contains a header, and the former is around 10,000x larger than the latter. As you might have realized, data structures form the foundation of blockchain. Learning about data structures will ensure that you know the basics of blockchain. Having a strong foundation helps you in understanding the advanced concepts more quickly.
As a blockchain developer, you’ll be mostly spending your time developing web apps. You’ll have to learn web design, development, and programming of apps, all of which will help you in developing better Dapps. Web development is crucial because most organizations require blockchain developers to create apps that people with no or minimal knowledge of blockchain could use.
To make transactions of cryptocurrencies, you’ll need to have a wallet and the key to that wallet. That key proves your ownership of the wallet, that’s why it’s essential. Save transactions of cryptocurrencies take place through encryption and decryption of public and private keys.
Another essential concept of Cryptography is cryptographic hashing. Hashing in cryptography means to produce an output of a specific length from an input of any length. The hash function could have information with 20 characters or 200 characters, but its output would only be of the length you’ve chosen.
Certainly, cryptography is vital for the proper workings of blockchain technology. You should learn about it and its various aspects, including the topics we’ve discussed here. With its knowledge, you’ll be able to keep your blockchain data safe.
6. Fundamentals of Object-Oriented Programming
OOPs, or object-oriented programming forms the foundation of most of the programming world. And just like that, it forms an important component of the blockchain world too. Having a good hold on it will help you reuse code, solve complex problems, gain flexibility through polymorphism, and use modularity for easy troubleshooting.
7. Understand Standards and Eco-systems
To build an effective blockchain system, to simplify your business process and drive the business outcome, get familiar with blockchain principles and practices, and understand how they can be applied within your business environment.
As we all progress towards the year 2021, we’ll be seeing a lot more growth of the blockchain industry. Many big giants like Facebook, Twitter, Tesla are all already shifting to this wonderful tech, and still, a lot has yet to be discovered in it. Want to be part of this movement? Why not start by taking this online blockchain certification and give your career the much-needed boost. It is reported that blockchain jobs have seen a rise of almost 271% in just 2020 and is expected to quadruple by 2022.
