One quick search on job hunt platforms like LinkedIn and AngelList reveals that the Blockchain field is one of the highest paying in the job market right now. One of the most active buzzwords in the tech field, Blockchain is widely regarded as the “Technology of the Future”.
Because Blockchain is popular, and because users want to move to a decentralized web, and because businesses see the market potential of the technology, Blockchain has become the focus of attention in the tech field.
So many successful Blockchain startups have emerged in just the past few years that even well-established multi-billion dollar industries (like IBM, JP Morgan, VISA, Walmart, etc.) are keen to get involved.
The demand for blockchain developers is increasing rapidly. This high-demand, high-skilled job pays well, which is one of the primary reasons why those in the tech field are quickly adapting their skillsets to incorporate blockchain development.
What is Blockchain Technology?
Blockchain is a database where information is stored in the form of data blocks that are chained together in chronological order. Whenever new data is generated, it is written onto a block. Once the block is full, it is timestamped and then attached to the last block in the chain, making a chronological chain of blocks.
Blockchain can be used for different things, but it’s most well-known for being a financial transaction ledger.
The Blockchain’s immutability and decentralization make it a very secure transaction ledger.
If a hacker wants to change the data in the block, he would also have to change the hash associated with that particular block. Once some data is written onto a Blockchain, it can’t be changed. Whenever a block is added to the Blockchain, it gets a unique hash value associated with it. If a hacker wants to change the data in the block, he would also have to change the hash associated with that particular block.
If the data on a block is changed, the hash value will also change and the Blockchain will be considered tampered. This ensures that once a transaction is written to the Blockchain, it cannot be modified by anyone. Therefore, the Blockchain is a reliable ledger system.
If a hacker wants to change the records in the database, e.g., alter transaction details, then he has to change it in all the copies of the decentralized database. Meanwhile, the term “decentralization” is quite self-evident, referring to something that is not centralized. This is one of the key features that makes Blockchain stand out. In a nutshell, each node (a computer that stores and runs the digital database that is Blockchain) in a Blockchain network maintains a copy of the Blockchain. So if a hacker wanted to tamper with records in the database, say by altering transaction details, they would need to make the same changes to every copy of the decentralized database.
When a transaction happens on the Blockchain, it gets checked and confirmed by more than one node. This makes it so that even if one node tries to record a fake or incorrect transaction, the other nodes will catch it and reject the transaction. This makes the system more dependable and safe.
Who is a Blockchain Developer?
A blockchain developer is someone who creates applications that work with the blockchain protocol. This includes creating algorithms that work within the protocol and making sure that they are effective.
A Blockchain developer’s job roles include writing smart contracts. Smart contracts are programs that run on the Blockchain nodes.
A Blockchain developer creates applications that work on the decentralized version of the internet called Web3.
The roles of developers can be broadly classified into two categories depending on the nature of the tasks they have to perform.
A core Blockchain developer is responsible for designing and developing the Blockchain architecture. They decide upon the system protocol and the consensus mechanism.
As a blockchain software developer, you will be responsible for developing applications that run on the blockchain. You will use the algorithms developed by core blockchain developers to create decentralized applications.
How to Become a Blockchain Developer?
There is a current high demand for Blockchain developers and not enough skilled professionals to fill the roles. Blockchain is constantly evolving which leaves a lot of room for innovation. Now is a great time to learn the necessary skills to become a Blockchain developer.
There is a lack of skilled professionals to fill up vacancies in the Blockchain industry due to the steep learning curve associated with the technology, and the vast set of pre-requisites one has to cover in order to become a Blockchain developer.
- Just like any other field in computer science, one has to start with learning the basics of programming. This involves learning a programming language like C++, Python, Java etc., followed by data structures and algorithms to enhance your problem-solving skills, and further strengthen your logical and programming foundations.
- The next step is to cover the foundational concepts in Blockchain— Blockchain architecture and cryptography. We’ll understand these in detail in the next section.
- With these covered, the next step would be to learn how to use some of the essential developer tools and programming languages for Blockchain programming. This involves writing smart contracts, developing and optimizing consensus algorithms, etc. This is where you actually start doing some hands-on as a Blockchain developer.
- Once you master this aspect of Blockchain programming, you move on to the next part— creating decentralized applications. Here, you have the option of mobile app development to target mobile users, or web development to target a web-based user base. This can be treated as an entirely different field on its own, with an extensive set of tools and frameworks that can be used to implement a variety of features.
After ensuring that you meet all the qualifications for a Blockchain developer, you will be ready to apply for the role.
What is the Demand for Blockchain developer?
The current demand for Blockchain developers is 2000-6000% higher than it was a few years ago.
According to the text, Blockchain developers earn 50-100% more than regular software developers. This trend is expected to continue, as more and more large companies get involved in Blockchain technology.
Once we take a look at some statistics, it will become more clear how much a Blockchain developer makes on average in a year.
Blockchain Developer Salary
As we have seen, developers who work with blockchain technology are some of the highest-paid in the world. This is because there is a high demand for this technology, and because more and more people are moving to using “Web3” technology.
A survey found that the yearly salary for a blockchain developer in India ranges from 5 lakh rupees to 30 lakh rupees, with some senior developers earning up to 50 lakh rupees per year.
In the US, the average annual salary for a blockchain developer is $135,000, although there is no definitive upper limit; some developers make as much as $200,000 per year.
The table above shows the difference in pay for Blockchain developer roles by region. In India, the salary is higher than what an average software developer makes, taking into account the low cost of living.
A Blockchain developer’s experience and skill level is a crucial factor in determining their salary. Generally, the more experience a Blockchain developer has, the more value they contribute to the company, and thus the higher their pay.
Blockchain developer jobs: what else do you require?
The following skills are required for blockchain developer jobs: compiling, testing, and deploying code. However, there is more to it than that. We will provide you with some additional information and course suggestions.
Data Structure & Blockchain architecture
It is important to have knowledge of data structures and blockchain architecture because blockchain systems are based on the data structure. Blocks are groups that confirm transactions in relation to open registrations.
A blockchain data structure can be used to store information about payments, property, DAO’s, or proof of ownership.
Any changes to the blocks will modify the hash, which can make a chain inaccurate. As a result, you should study and be aware of data structure and remember the key components:
- Blockchain technology can be divided into four main types;
- Public blockchain networks require independence, transparency, and trustworthiness. They are used for cryptocurrency investments and document validations.
- in these use cases, known permissions and access rights enhance security and reduce the risk of fraud. There are two main types of blockchain – private and public. A private blockchain is permissioned, meaning that only certain people can access it. They tend to be faster and more secure, because only people with the correct permissions can view and edit the data. This makes them ideal for use cases where security is important, such as supply chain management and asset ownership.
- Hybrid blockchain provides a balance between scalability, performance, and access, while still allowing for some degree of transparency. This makes it ideal for use cases such as medical records and real estate systems.
- Finally, there are consortium blockchains, which are more secure and scalable than other options, making them a better choice for industries like banking, research, and supply chain management.
To improve your skills, keep studying and practicing. Udacity offers two courses that could help you: Data Structures & Algorithms and a course to become a blockchain developer.
Cryptography for blockchain developers
Cryptographic concepts include learning how to operate keys, digital signatures, and wallets. This also includes concepts such as public key cryptography and hashing.
It should not be surprising that blockchain developers need to have a good understanding of the technology.
In the web3 world, there are smart contracts and wallets that operate with assets such as cryptocurrencies, NFTs, and others. They must be safer than a safe box to prevent unwanted access to data.
Therefore, it is critical to scrutinize how to turn plaintext into cyphertext (a sequence of bits) and how to convert the encrypted message into unencrypted text.
However, there is a need to go much further. In blockchain cryptography, there are some methods that can be used, especially:
- A hash function is a mathematical function that converts a numerical input value into a compressed numerical value. Hash functions are used to create blocks on blockchains to keep track of all transactions.
- A symmetric key is a type of cryptography where a single key is used to encrypt and decrypt data.
- This type of cryptography uses a pair of keys to encrypt and decrypt data. One key is private and the other is unique and public.
Interoperability skills: connecting APIs
It is also important to know how to transfer data from one blockchain to another. This is called interoperability.
It was not possible to share data across different blockchain architectures, but now it is possible and it is crucial to do so. Remember, there are four different blockchain models that you can work on as a blockchain developer.
It is critical to make data capacity transfers easier in order to accomplish this interoperability. The answer lies in APIs, or Application Programming Interfaces.
One of the most prominent examples of a cryptocurrency exchange is Coinbase, due to its multiple and quick cryptocurrency support. This means that it integrates with existing APIs that the consumer is unaware of.
This occurs because APIs deliver data without requiring cross-platform verification, and a blockchain API can communicate with nodes or services on different blockchains. Here are two more pointers:
You can read a very good blog post about blockchain APIs by Jelvix here.
Professor Chow’s course offers a comprehensive look at Cryptography, API, and dApps so you can improve your understanding of all three concepts in one place.
Smart contracts
0. Many people dream of a world where goods and services can be exchanged without the involvement of a third party. This is becoming a reality through the use of self-executing contracts, also known as smart contracts, on web3.0.
To become a blockchain developer, you must learn how to write code on some programming languages, such as Vyper, Solidity, and Chaincode.
Being a blockchain developer requires more than just technical skills. If you can learn how to handle the challenges that come with the job, you’ll be more successful than other developers who lack that experience.
Smart contracts are popular because they can be used on the Ethereum decentralized network. This network makes it easy for two parties to do business with each other without needing a third party, like a bank, to oversee the transaction.
Smart contracts are a convenient way to transfer NFTs or certify ownership of real-world assets.
Earning while Learning Web3
We understand that it can be tiresome to attend classes, read new material, and revise it.
This is part of what it takes to be successful. It is important to be able to bounce back from setbacks.
