Top 5 Needed Skills for Blockchain Development Jobs

The five blockchain developer skills listed below are usually recognized as essential for launching a career in blockchain development. It's important to note that there are many more skills you'll need to acquire, but this is a great place to start! We'll look at a few intangible talents required to flourish in this industry towards the end of this book.


1) Previous Software Development Experience

Most developers that enter the blockchain field have prior software development experience. Initially, this was the industry standard because blockchain technology was complex and still in its early stages.


Now that blockchain technology has been around for more than a decade, we are seeing more engineers begin their careers in this discipline rather than in more traditional tech fields.


Make no mistake, however, software development experience of some kind is extremely valuable. Intense instruction, such as that provided by university computer engineering courses or immersive study groups, is advantageous.


Even simple web or mobile apps that do not involve blockchain technology are required for learning developer best practices.


2) APIs stands for Application Programming Interface (APIs)


An application programming interface (APIs) connects numerous end-user programs.


APIs are common in the IT sector nowadays and are frequently utilized in online and mobile applications. When you shop online, for example, an API sends a request to a server that contains the essential data and returns the result to your device.


APIs are a method of directly or indirectly connecting a blockchain node or a client network. Many cryptocurrency exchanges, for example, offer APIs to make it simple to access real-time trade data.


APIs are also used to collect information about cryptocurrency transactions, account or wallet administration, analytics, and security.


While many APIs are only available as a subscription service, there are a plethora of open-source APIs.


You'll need to know how to connect current APIs to your blockchain applications as a blockchain developer.


It's also likely that you'll write your APIs for other developers who wish to use the technologies you're developing.


3) Fundamental Blockchain Development

Core blockchain development, also known as protocol-level development, is primarily concerned with the creation of blockchain protocols, mechanisms for blockchain consensus, network design, and peer-to-peer network security mechanisms.


Some blockchain networks use C++, Golang, and Java as programming languages. Satoshi Nakamoto built the Bitcoin Core code in C++. Many Bitcoin forks, such as Bitcoin Cash and Litecoin, have continued to modify the original Core C++ codebase to satisfy the needs of their development groups and users.


With the advent of smart contract platforms and open-source technology, it may appear that core blockchain development is becoming less vital, but this is not the case. Blockchain network cores are always being improved.


Furthermore, with the growth of third-generation blockchains such as Cosmos, Solana, and others, as well as discussions of developing fourth-generation blockchains, core blockchain development may be more valuable now than ever before.


4) Intelligent Contracts

If the protocol is the foundation of the blockchain, the remainder of the structure is a smart contract. A smart contract is a contract that executes itself on a blockchain. An ERC-20 token smart contract is the most common example nowadays.


Solidity is a blockchain programming language that is mostly used with Ethereum. Assume you want to create a decentralized application (dApp) that allows users to rapidly and simply generate tokens on a blockchain.


ERC-20 tokens can then be listed on IDOs, traded on DEXs, and sent/received in crypto wallets that support them. Smart contracts, in addition to asset generation, serve as the foundation for the expansion of new blockchain use cases.


Assume you wish to create a decentralized app for a trading protocol, lending/borrowing platform, or perhaps a gaming game. The application's rules are based on the execution of some form of smart contract technology.


Although Ethereum popularized smart contracts, it is far from the sole blockchain platform that supports them. Developers can also use Avalanche, Qtum, Binance Smart Chain, and other protocols to create sophisticated apps driven by smart contracts.


5) Data Structures and Algorithms


The most important aspect of blockchain technology is algorithms. In a nutshell, algorithms are the rules or circumstances that govern how a blockchain operates.


Consensus algorithms, also known as consensus mechanisms, are critical because they validate digital signatures, confirm balances, evaluate the validity of a block, and determine how a block is formed, among other things. Proof of Work, Proof of Stake, and Delegated Proof of Stake are popular examples.


Mining algorithms such as SHA-256, Scrypt, and Equihash are another form of algorithm that plays an important part in security for Proof of Work blockchains. Nowadays, blockchain networks use cryptocurrency mining to power transactions worth trillions of dollars.
