Hire Blockchain Developers

Blockchain is a decentralised, immutable ledger that enables the recording and management of transactions and assets within a business network. By leveraging blockchain technology, users can safely and securely trade virtually any kind of valuable asset, while reducing the risks and costs associated with traditional methods. Core blockchain engineers are tasked with building the framework and security of a blockchain system. Consequently, the demand for blockchain developers with specialised skills and knowledge has increased significantly. Expert blockchain developers are responsible for constructing decentralised applications (dApps), web applications and smart contracts based on the foundation and architecture established by the core developer.

Blockchain technology is an excellent solution for data delivery due to its ability to provide immediate, shareable, and completely transparent data. All data is kept on an immutable ledger that is only visible to authorised network members, allowing for a secure and reliable way of tracking orders, payments, accounts, production, and other types of data. By allowing members to share a unique perspective on the truth, the entire process is visible from start to finish, providing a higher level of confidence and greater efficiency when compared to traditional methods. This in turn gives businesses more possibilities to explore.

What role does Blockchain development play?

With the increasing popularity of the Internet of Things (IoT), it is no surprise that blockchain technology is gaining traction. Predictions state that by 2030, there will be an estimated 50 billion IoT devices in use globally, which further highlights the potential for blockchain technology. The banking industry has already seen the vast potential of blockchain technology, and its promising future will only be further strengthened by the expansion of IoT. As a result, there will be a growing demand for professionals skilled in blockchain technology.

In India, the Reserve Bank of India has recently highlighted the potential of Blockchain technology in preventing forgery, transforming the way financial institutions, collateral authentication, and payment systems function. They have encouraged banks in the country to adopt digitization post-demonetization. Incorporating Blockchain into financial transactions can offer multiple advantages such as cost-effectiveness, faster transaction processing, and better transaction validation. The distributed ledger technology that forms the basis of Blockchain is highly secure and can help protect against cyberattacks. This makes it an attractive career option for those looking to enter the field of technology in 2022.

What are the duties and obligations of a Blockchain developer?

Being a blockchain developer requires proficiency in a wide range of areas. It is not only about understanding the architecture and consensus design of the system.

  2. Developers who have worked in sectors similar to Blockchain.

In order to qualify for a position as a Blockchain Developer, it is recommended that applicants possess a Bachelor’s or Master’s degree in Computer Science or Information Technology. Although a specific academic background is not absolutely necessary to secure a job in this field, having a degree in a relevant field can provide a solid foundation for quickly learning and understanding the fundamentals of Blockchain Technology.

In order to join the Blockchain Development Domain, it is essential to demonstrate a broad range of technical capabilities. After acquiring the necessary technical skills, it is important to thoroughly understand the fundamentals of Blockchain Technology, including how it works and what possible applications it can be used for. Furthermore, a comprehensive knowledge of Blockchain architecture, consensus, hash functions, distributed ledger technology, Smart Contracts and Solidity will differentiate your candidacy and significantly enhance your Blockchain developer resume. It is therefore imperative to dedicate sufficient time to learning and understanding all of these topics.

In order to gain a comprehensive understanding of Blockchain Development, it is essential to gain firsthand experience in the industry.

Qualifications for becoming a Blockchain developer

It is impossible to be a master of all aspects of blockchain development, as the technology is still relatively new. Therefore, it is important to understand the key skills and abilities that are necessary for a successful career in blockchain development. In this article, we will explore the essential skills and knowledge required for blockchain developers.

  1. Data organisation

    Blockchain programming requires a strong understanding of data structures in order to build and develop systems. Data structures form the backbone of the Blockchain system, with each block representing a data structure and containing a ledger of transactions within the public register. The header of some blocks on the Blockchain Platform is much smaller than the block itself, which highlights the importance of data structure knowledge in understanding the behaviour of the block, the most basic element of Blockchain. Having a sound understanding of data structures will help to create a strong foundation for learning complex topics more quickly and efficiently.
  2. Intelligent Contracts

    Smart contracts are a concept that presents a number of potential opportunities to professionals who are new to the blockchain space. Since the dawn of Ethereum, smart contracts have been an integral part of the blockchain industry and it is important for those new to the space to familiarise themselves with this concept. It is expected that smart contracts will be beneficial to all blockchain systems as they minimise the need for a third-party intermediary in the exchange of goods and services. When all parties to the contract have satisfied their obligations, the smart contract is automatically carried out due to the decentralised nature of the blockchain. As a result, smart contracts are more efficient and cost-effective than traditional transactions.
  3. Cryptography

    Cryptography is the practice of creating techniques and algorithms to protect personal communications from being read and understood by foreign entities during a transmission session. This is achieved by using two terms from the ancient Greek language, kryptos and graphein, which mean “hidden” and “to record” respectively. The following terminologies are commonly used in cryptography: encryption, which is the process of transforming plaintext into an unrecognisable sequence of bits known as ciphertext; decryption, which is the opposite of encryption and involves the conversion of encrypted text back to its original form; and the critical, which is a small amount of data required to activate the cryptographic method. A cipher is a specific cryptographic technique that converts plaintext into an encrypted message using a mathematical operation.
  4. Interoperability abilities

    The ability to securely observe and collect data from multiple blockchain networks is known as interoperability. Will recipients of data transmitted to another blockchain have the capability to effortlessly comprehend, review, and respond to it? Sadly, this is not currently achievable due to the lack of compatibility between the Bitcoin and Ethereum blockchains, making it impossible to share data between them.
  5. Blockchain Technology

    Blockchain architecture is an essential component of any blockchain specialist’s portfolio, as it is an integral part of the blockchain ecosystem. It is important for professionals to gain an understanding of the relevance of a ledger in the blockchain world, the concept of consensus, and the mechanics of smart contracts. Additionally, it is necessary to become well-versed in the three types of blockchain architecture: private, consortium, and public. Private architecture is used to secure sensitive data within a private network. Consortium architecture is a hybrid approach that combines the best of both private and public blockchain models. Lastly, public architecture is an open and decentralised system that allows anyone to join the network and verify transactions. Understanding the nuances of each of these architectures is critical for those looking to specialise in blockchain technology.
