Introduction

Debuting in 2008, blockchain is redefining the web world. It is fast making inroads into various industries beyond its source of origin, cryptocurrency. Blockchain technology is growing at an unprecedented rate, powering innovative ideas and concepts in the financial sector and laying new foundations for economic and social systems. From a security perspective, it's breaking new ground. As a result, its demand has increased, so it needs skilled blockchain developers. This demand has inspired many people to consider and opt for a career in blockchain development & opt for advanced programming courses

So, for the uninitiated, let’s first understand the basics of blockchain.

What is Blockchain?

Blockchain is a digital system that enables people (who may not know each other) to engage in trusted transactions with complete trust and confidence in the veracity and integrity of the assets being exchanged.

In other words, distributed ledger technology (DLT) – is a digital system that stores and manages the record of sender IDs and templates. It eliminates any point of failure and keeps a temper-proof track of the transactions and assets in a business network.

But what's with "blocks"?

A blockchain consists of blocks - each containing a transactional data unit. The blocks are stored sequentially and linked together by cryptographic hash. The hashing process makes it difficult to change a block's data once it has been added to the chain, which results in a highly secure and unchangeable system.

Getting its start with Bitcoin, blockchain is increasingly proliferating into industries like banking, healthcare, education, telecommunications, retail, energy, and financial services. Global giants like Oracle, Amazon, IBM, and Microsoft are also recognizing and promoting the benefits of blockchain. IBM is leading the way and has equipped supply chain networks with blockchain technology. Laying the groundwork for revolutionary development in specialized and advanced sectors, blockchain has resulted in a slew of new work prospects for techies and programmers. Companies need qualified and skilled blockchain developers to build their networks and applications. Let's get an in-depth understanding of the roles, responsibilities, and skills required to be a specialized blockchain developer.

Who is a Blockchain Developer?

Blockchain developers develop applications for blockchain architecture, its technology and what it takes to execute individual blockchain components into a consolidated system. Blockchain developers are also required to build decentralized applications and write smart contracts, which are nothing but programs developed for the blockchain running on blockchain nodes.

ROLES-AND-RESPONSIBILITES

Blockchain developers with specialized skills may have to don many hats depending on the organization and their roles and responsibilities. A blockchain developer has to:

  • Be proficient in programming languages since they need to build the blockchain components
  • Research, evaluate and design blockchain networks and decentralized applications
  • Research and thoroughly analyze the latest tools and technologies and assimilate them into blockchain networks and their applications
  • Plan and design and comply with security across the blockchain network 
  • Create, test, supervise and maintain blockchain networks and their performance
  • Create, test, supervise and maintain intelligent contracts, robust back-end systems, and applications for clients

Types of Blockchain Developers

Blockchain developers are typically classified as core blockchain and blockchain software developers. 

  • Core blockchain developers are concerned with blockchain networks and their elemental architecture. They plan and create robust networks, design protocols, and supervise and optimize the environment. 
  • Blockchain software developers develop decentralized applications and smart contracts to run on a blockchain network, keeping in mind the architecture of the network and protocols.

Let's now look at the top 6 skills required to be an ace blockchain developer:

Since blockchain is still evolving and different organizations have different requirements, blockchain skills may have to be tailored to a specific company's needs. Skills acquired through excellent theoretical and practical training can catapult your career to another level. Our Blockchain Online and Certification Training provide a hands-on learning experience that makes you industry-ready. However, there are six must-have skills that every blockchain developer must possess. 

1. Blockchain Architecture Skills

Blockchain architecture is central and critical to comprehend. Blockchain developers should thoroughly understand how blockchain works and the basis of the architecture. They should be proficient in cryptography, consensus, distributed ledgers, hash functions, smart contracts, and other concepts central to understanding blockchain's core workings. Developers should also be well-versed in the four types of blockchain architecture: public, private, consortium, and hybrid.

  • A public blockchain architecture ensures everyone who wishes to be involved can access the information and use the platform (e.g., Bitcoin and Ethereum systems are public). The complete information is accessible to people in a public blockchain, meaning anyone can participate in the entry process. However, it is inefficient because it takes a long time for each additional entry to be accepted into the blockchain infrastructure. 
  • Private blockchain architecture is managed only by members from a single business or approved clients who have been invited to participate. Since it is managed by only one organization, it is exclusive and has more anonymity. A private blockchain is more centralized, whereas a public blockchain is open-ended and decentralized.

  • The consortium architecture is not decentralized, and all network participants have complete control over it. As a result, it is appropriate for use cases involving multi-organizational groupings. 
  • Hybrid architecture, or the best of both worlds, combines public and private blockchains. A blockchain revolution allows organizations to create a private permission system alongside a permissionless public system. Transactions are not accessible to everybody in such blockchains but can be made public for verification purposes. It is critical to note that even though a single entity owns the hybrid blockchain, it still cannot be altered by that organization. 

2. Data Structure Skills

A blockchain network consists of data structures and is the primary skill a blockchain programmer or developer should have. Each block is considered a data structure that clusters transactions for the public ledger. Blockchain developers must frequently work with data structures and understand how the blockchain network uses them. Blockchain developers should also be familiar with various data structures, such as graphs, heaps, hash, Patricia and Merkle trees. 

3. Smart Contracts Skills

Smart contracts are self-executing contracts enabling two parties to exchange goods and services without an intermediate entity. Smart contracts have become essential to blockchain implementations, and developers should thoroughly understand what they are and how they administer and support the business rationale. The decentralized structure of blockchain adds to the productivity of smart contracts.

Developers who want to make a career in blockchain development should know intelligent contracts and their relevance in business. Blockchain developers should also be well-versed in the programming languages commonly used for smart contracts, such as Chaincode, Viper, and Solidity. Solidity is the best introduction to the blockchain world, and JanBask Training provides the perfect platform for aspiring developers.

4. Cryptography Skills

Cryptography is a method used to design processes and algorithms to prevent a foreign entity from decoding, reading, and learning content from personal messages throughout a communication session. Effective cryptography is essential to providing a secure blockchain environment, and developers should have a solid foundation in cryptographic concepts and practices, including keys, wallets, and digital signatures.

A wallet is essential for any cryptocurrency transaction. Every wallet has a key, which indicates the wallet's owner. Also, encoding digital security measures, such as block ciphers, message integrity, and authenticated encryption is an essential skill to master. With computers becoming smarter and more sophisticated, cryptography is predicted to gain relevance as one of the top blockchain developer skills in demand.

5. Programming, Programming Languages, and Web Development Skills

Knowing how to create a set of instructions for an application to follow are essential to a developer's toolkit. Because of the emergence of cybersecurity, developers should learn how to write hack-proof code. Learning Java, C++, Solidity, and Python, the most commonly used languages in creating blockchain domains, is an excellent place to start with. You can enroll yourself in Python learning and certification to get started now. Also, a bonus is languages like JavaScript, Scala, Simplicity, Ruby, Go, Rholang, Rust, and PHP.

Blockchain and web development are hand-in-glove, especially with blockchain emphasizing decentralized applications. Blockchain developers should be well-versed in web development and its features. Since they spend a significant amount of their time on web apps, they will need to learn about web development and designing, programming apps, and more. In-depth knowledge and understanding of web development best practices will help you create compelling apps faster. Since most companies hire blockchain developers for web and app development projects, thorough design knowledge of developing web applications, understanding the tools and technologies that support them, and what it takes to optimize and secure them are fundamental to web developers.

6. Blockchain Interoperability Skills

Blockchain interoperability allows different blockchain protocols to communicate actively with each other. Therefore, different chains can interact and share data, making it easier to use different blockchain networks. Let's consider the familiar analogy of emails. We send emails every day, and one of the essential functions of all email systems is someone with an Outlook account can send emails to someone with a Gmail account.

One of the most fundamental ways to accomplish interoperability between blockchains is to make data capacity transfers seamless and more effortless. Blockchain interoperability is accomplished by using application programming interfaces (APIs), which are developed to accommodate information to be exchanged with each other. Newer projects are slowly buying the idea as they try to build platforms that can communicate with each other without the interference of a third party.

Blockchain-Architecture-Skills

 

Blockchain interoperability should go a long way in eliminating intermediaries or third parties synonymous with centralized systems. The ability of different decentralized networks to communicate with one another without any intermediaries should thus go a long way in giving a push to fully decentralized systems. Many developers are already working on optimal solutions with the ever-growing need to enhance the connection between various blockchain networks. The number of blockchain interoperability projects is on the rise as a result as blockchain developers look to accelerate blockchain mass adoption.

Polkadot blockchain, Blocknet, Aion Online, Wanchain, and Cosmos Blockchain are some of the top blockchain developer course projects looking to enhance blockchain interoperability.
