How To Become A Successful Blockchain Developer?

Fawzan Hussain 1 November, 2021 | 11 min read

Blockchain is one of those tools that can assist you in achieving your programming objectives. In the previous several years, the demand for blockchain has skyrocketed. Blockchain was and still is a promising technology, but the true growth and demand began when bitcoin took off. It attracted the interest of a variety of industries, which means you'll have additional career prospects!

Blockchain is still relatively young, with less than 1% of the world adopting it. You could be a part of this process if you take the time and put in the energy to learn about blockchain. It will also open up more doors in the future. You'll be able to grasp cryptocurrencies and initial coin offerings (ICOs) on a technical level. This implies you'll be prepared to operate on cryptocurrency and initial coin offering (ICO) initiatives. These ideas might also assist you in becoming a better investor or trader.

Blockchain provides a completely trustworthy network. As a result, it's an excellent choice for developing systems or services that require enhanced security and identity verification. Transparency will also benefit from the use of blockchain. Newer technologies, such as the Internet of Things (IoT), are also important in the shift. The ultimate goal is to employ blockchain and other similar technologies to create a secure network.

What does a blockchain developer do?

Blockchain is a technique for storing transaction details in a block that happens in the blockchain network making them impossible to alter or hack, making them immutable. A blockchain is essentially an online public ledger of transactions that is duplicated and distributed across the computer network systems that make up the blockchain.

A blockchain developer is a programmer who works on blockchain-related dApps, smart contracts, networks, architecture, as well as optimising and developing them. In essence, blockchain engineers allow safe digital transactions by developing systems and applications that record and preserve block data while preventing external alterations or attacks.

Types of blockchain developers

Blockchain technologyuses a distributed database that keeps track of every activity that has occurred over a global network of computer systems. Core blockchain developers and blockchain software developers are the two categories of blockchain developers. Each category has its own set of tasks. Let's take a closer look at each one.

Naturally, the Blockchain developer is expected to face obstacles. For example, the developer needs to work with ancient infrastructure and its restrictions and still fulfil the requirements of a development plan from Blockchain. There are also obstacles to comprehend the technical practicality of the implementation of decentralised cryptosystems, which are non-traditional IT development processes, which implies that a developer from Blockchain needs specialist expertise. It is the role of the Blockchain developer to develop unique solutions to difficult issues. In addition, the developer carries out sophisticated analyses, design, programming, certification and computer debugging, particularly for different product hardware or for companies' technical service lines.

How To Become A Blockchain Developer?

Now that we know what a blockchain developer is, what types of roles they play, what their responsibilities are, and what technical skills they need, it's time to walk through the stages to become one.

Learning the basics of blockchain

Basis.jpg

You must begin with the fundamentals, like with any other technology.

This comprises the fundamental concepts, ideas, and architecture of the blockchain. Learn about decentralisation, including its public and private approaches, including use of consensus in network decision-making, and more. Furthermore, learning the blockchain vocabulary to comprehend the majority of the key topics.

Learning the fundamentals also entails being acquainted with popular blockchain development tools. You must familiarise yourself with the industry in addition to the technical elements. Learn about initial coin offerings (ICOs) and cryptocurrency.

Aside from that, immerse yourself in cryptography and ensure that you are familiar with all of the primary cryptographic algorithms utilised by prominent blockchain systems. Finally, you should become familiar with the blockchain ecosystem. The blockchain ecosystem has evolved significantly in recent years. After you've learned about the topics given below, you'll be ready to go!

  1. Blockchain platforms for businesses.
  2. Hyperledger, Quorum, Corda, and Ethereum Enterprise are examples of blockchain as a service (BaaS).
  3. Learn about some of the most popular dApps.

Get to know about the working of blockchain

Now that you've mastered the fundamentals, it's time to practise real-world application. It's easy to discover students or developers who claim to be blockchain developers but haven't created anything. For starters, choose an exchange that you want to participate in. You would be capable of understanding what cryptocurrency has to offer by going through elementary cryptocurrency. Keep in mind that bitcoin is only one application of blockchain. This is the first application of blockchain technology. Wallets must be created to store the coins. They are electronic and simple to create. However, make sure you're familiar with private keys and how to keep them safe.

Start coding

After having a firm grasp of the fundamentals and applications of cryptocurrencies, it's time to get serious about coding. Solidity is a good place to start for beginners. It will assist you in creating and developing Ethereum-based dApps and smart contracts.

One could also look at the open-source code of several blockchain platforms. The code for the majority of blockchain platforms or solutions is open source, making it easy to examine or understand. Establishing or handling an open-source blockchain, on the other hand, is a difficult task. It necessitates overcoming obstacles including privacy, efficiency, resource management, and solitude.

In a nutshell, you must perform the following -

  • Make a basic block.
  • Turn it into a blockchain.
  • Learn about the genesis block and how to use it.
  • The blocks are added to the blockchain.
  • Verify the chain.
  • Make use of it by putting it to the test.

You'll have a perfect blockchain once you perform the above steps correctly.

Learn about smart contracts and Solidity

Smart contracts .jpg

One of the most important blockchain ideas to understand is smart contracts. It's a computer protocol that's analogous to a real-life contractual obligation. It can be used to simplify or enhance your dApps' performance. A smart contract must have three key characteristics: it must be logical, configurable, and isolated. Further, Solidity is a statically typed, high-level language that is strongly impacted by JavaScript and is used to construct smart contracts. Vyper, Simplicity, and several other specialised languages are also available for building smart contracts.

Lastly, continue to read blockchain-related material. Numerous websites provide high-quality blockchain content.

Types Of Blockchain

Ethereum blockchain

Etherem Blockchain.jpg

The Ethereum blockchain is a smart contract platform that is decentralised and open-source. It is the most widely employed blockchain platform due to its smart contract capabilities, which allows Dapps to be written on it. It now employs Proof-of-Work (PoW) as its consensus method, but because of PoW's excessive energy consumption, it hopes to replace it with Proof-of-Stake (PoS). The renowned cryptocurrency Ether is likewise powered on blockchain technology (ETH).

Bitcoin blockchain

Bitcoin.jpg

The Bitcoin cryptocurrency is powered by a distributed ledger. Proof-of-Work (PoW) is the consensus mechanism used by this blockchain. Since PoW consumes a lot of energy, this consensus process has recently become a point of dispute. Apart from supporting the cryptocurrency, the Bitcoin blockchain has no other use.

Cardano blockchain

Cardano Blockchain.jpg

It's a decentralised and open-source blockchain technology that relies on Proof-of-Stake (PoS) for consensus. It is the blockchain framework that underpins Ada, a famous cryptocurrency. Cardano, unlike Ethereum, is created using evidence-based processes and peer-reviewed research. This implies that before being adopted, discussed and recommendations must be subjected to academic investigation. The Haskell programming language is widely used in the banking and finance industries, and this blockchain technology is based on it.

CryptoZombies and Space Doggos, as crazy as their titles sound, are courses that teach you Solidity Code, which is the code required to write smart contracts, placing you on the correct track to understanding Blockchain development. Space Doggos is very useful since you construct your space dog using Solidity code. These are enjoyable and exciting methods to learn about Blockchain's evolution, and they're probably a little less overwhelming.

Learning a different programming language

A professional Blockchain developer should be able to work in a variety of programming languages. Solidity - This is the programming language that Ethereum smart contracts are written in. Haskell - The Cardano blockchain was built using this programming language by the primary blockchain developers. Javascript - Interfaces are created with this program. C++ and Go - The backends of blockchain systems are built using these two languages by blockchain core developers.

You must be able to remain with the company, at least for a certain term, if you are someone who works in an undertaking paying for your upscale charges and wants to place you in the position of developer Blockchain. After all, companies don't pay for the training of staff just to make them more trademark

Companies that are hiring Blockchain developers

Blockchain Companies.jpg

Between February 2018 and February 2019, job posts for blockchain, bitcoin, and cryptocurrency increased by 90%, according to new statistics from Austin-based job search portal Indeed. While a rise of more than 4,000% may look amazing, the context is all. For instance, in India in February 2017 there were 12 per million job posts relating to blockchain; the figure increased this February to 88,4 per million. In February, by contrast, 1,000 jobs per million posts were for data scientists. Indeed's data shows that job posts in certain categories increased by 4,086 per cent in the share of job listings per million during the last three years. So, while the number of blockchain job openings is rapidly increasing, the overall numbers still lag behind more established IT career options. Nonetheless, the number of job ads connected to bitcoin, cryptocurrency, and blockchain has increased steadily over the last three years, with a spike in the last two months. Whilst cryptocurrencies and ICOs have led to many initial interests in blockchain, companies are now driving the rise to understand the features of decentralised apps. As blockchain employment has developed, developers and others have programmes that provide the necessary blockchain skills. For instance, the University of California Berkeley had hundreds of signups after launching an online course on cryptocurrency and commercial blockchain networks.

Top jobs are primarily for developer, engineer or management roles and consulting rooms for blockchain posts.

IBM's Lowry recommends beginning with a wide awareness of the ecosystem and the range of blockchain protocols in a good position to get a blockchain developer job. Then discover Hyperledger Fabric and how to develop the components of a business-grade blockchain.

Hyperledger, Coursera, IBM developerWorks are all the means to learn how to become an engineer.

The top companies with the most job ads for bitcoin, cryptocurrency, and blockchain-related positions are:

  1. Deloitte
  2. IBM
  3. KPMG
  4. EY
  5. Accenture
  6. Cisco
  7. JP Morgan Chase
  8. Microsoft
  9. Conduent
  10. ConsenSys

Enterprise initiatives have grown over the last three years, progressing from proofs of idea in 2017 to pilots in 2018 to production environments this year, which is one reason for the unexpected increase in blockchain-related job posts. For four commercial applications, KPMG and other companies, in general, are mainly implementing blockchains.

The first concerns the inclusion of existing ERP systems. In the front office blockchain, for example, sales are activated and client data is collected shared throughout the distributed blockchain technology (DLT). It is required to monitor the supply chains, regulatory activities, and supply in the central office. Furthermore, blockchain is employed in the Back Office for financial tasks like accounting and cross-border business.

IBM tries to bootstraps its blockchain cloud service by pilots like Food Trust and TradeLens, an international cargo tracking service. Maersk tested TradeLens with 94 partners and Walmart pilot Food Trust, and by September this year, it even tells its suppliers to connect to the network.

But there are solutions for streamlining the data flow from ERP systems to a distributed ledger platform. Blockchain does not use middleware to plug in current traditional systems. Firstly, though, it must be determined whether companies even require it.

Companies also construct decentralised identities for staff using blockchain to establish secure access to business data and applications.

The third industry where blockchain takes routes is the IoT, where sensors can, for instance, share data about secure ledgers in intelligent buildings, manufacturing equipment or pharmaceutical products.

Finally, blockchain is used to produce physical or commercial tokenization or digital representation.

Most companies explore how it might produce efficiencies, while it may still be a new technology. Telco networks had taken years to establish pipes and create their infrastructure. From the inception of trade, transactions - blockchain bread and butter - began with old trading systems and exchange currency supported by commodities, including gold and government fiat.

Conclusion

This is therefore a whole route, to be a successful Blockchain developer. However, the way to a job is not so straightforward, and it demands a lot of commitment, hard work and perseverance on your part. However, the career sphere of Blockchain developers seems to be quite exciting and bright given the quick growth of Blockchain technology.
