A blockchain is a network of computers connected in some way and they collectively run what is called a blockchain client. The Bitcoin blockchain, Binance smart chain, and the Ethereum blockchain are examples of blockchain clients.
With that in mind, it makes perfect sense to explore becoming a Blockchain developer if you’re looking for a job with a lot of room for advancement and a vibrant new technology that’s just getting started.
If this prospect intrigues you, and you want to know how to become a Blockchain developer, then read on and find out all you need to know about this exciting and intriguing profession.
This tutorial explains how to become a blockchain developer and how to start a blockchain development profession from the scratch. The lesson is appropriate for training institutions and organizations as well as people seeking employment or training in this subject.
We’ll also go through the most important skills to have as a blockchain and cryptocurrency developer. Bootcamp, both coding and non-coding, is one of the most significant things for developers here. They may be used to learn and practice the necessary abilities.
Why is Blockchain Popular?
Simply send money from your bank account to your relatives or friends. By utilizing their account number, you would connect into online banking and transfer the money to the other individual. Your bank updates the transaction records after the transaction is complete. It seems to be fairly easy, right? Most of us overlook a possible problem that exists.
These types of transactions can be tampered with very quickly. People who are familiar with this truth are often wary of using these types of transactions, hence the evolution of third-party payment applications in recent years. But this vulnerability is essentially why Blockchain technology was created.
Technologically, Blockchain is a digital ledger that is gaining a lot of attention and traction recently. But why has it become so popular? Well, let’s dig into it to fathom the whole concept.
Record keeping of data and transactions is a crucial part of the business. Often, this information is handled in-house or passed through a third party like brokers, bankers, or lawyers, adding time, cost, or both to the business. Fortunately, blockchain avoids this long process and facilitates the faster movement of the transaction, thereby saving both time and money.
The majority of people believe Bitcoin and Blockchain may be used interchangeably, but that is not the case. However, Bitcoin is a currency that depends on Blockchain technology to be secure. Blockchain technology is capable of enabling different applications connected to multiple industries like finance, supply chain, manufacturing, etc.
Blockchain is an emerging technology with many advantages in an increasingly digital world:
- Time reduction: In the financial industry, blockchain can allow the quicker settlement of trades. It does not take a lengthy process for verification, settlement, and clearance. It is because of a single version of agreed-upon data available between all stakeholders.
- Unchangeable transactions: Blockchain registers transactions in a chronological order which certifies the unalterability of all operations, which means when a new block is added to the chain of ledgers, it cannot be removed or modified.
- Reliability: Blockchain certifies and verifies the identities of each interested party. This removes double records, reduces rates, and accelerates transactions.
- Security: Blockchain uses very advanced cryptography to make sure that the information is locked inside the blockchain. It uses Distributed Ledger Technology where each party holds a copy of the original chain, so the system remains operative, even if a large number of other nodes fall.
- Collaboration: It allows each party to transact directly with each other without requiring a third-party intermediary.
- Decentralized: It is decentralized because there is no central authority supervising anything. There are standard rules for how every node exchanges blockchain information. This method ensures that all transactions are validated, and all valid transactions are added one by one.
Features of Blockchain
Below are the most important features of Blockchain technology that have made it a revolutionary technology:
- SHA256 Hash Function
- Public Key Cryptography
- Distributed Ledger & Peer-to-Peer Network
- Proof of Work
- Incentives for Validation
Let’s try to understand each one of them one by one.
SHA256 Hash Function
The SHA256 hashing algorithm is the main one used in blockchain technology. The reason for utilizing a hash is that the output is not “encryption,” meaning that the original text cannot be recovered by decryption. It has a fixed size for any size of the source text and is a “one-way” cryptographic function. Let’s look at an example below to gain a better understanding:
If you look at the first example, we are feeding the input as “Hello World” and getting an output as “a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b57b277d9ad9f146e”. However, by just adding an “!” at the end, the output completely changes to “7f83b1657ff1fc53b92dc18148a1d65dfc2d4b1fa3d677284addd200126d9069”. If we change “H” to “h” and “W” to “w”, then the output value changes to “7509e5bda0c762d2bac7f90d758b5b2263fa01ccbc542ab5e3df163be08e6ca9”.
I hope with this example you have understood how complex the algorithm is as even the slightest change in the input can cause a massive change in the output.
Public Key Cryptography
This cryptographic technique helps the user by creating a set of keys referred as the Public key and Private key. Here the Public key is shared with others whereas the Private key is kept as a secret by the user. To understand the roles of these keys, Let us look at the example below to get a better understanding:
If Chandler sends some bitcoins to Joey, that transaction will have three pieces of information:
- Joey’s bitcoin address. (Joey’s Public key)
- The number of bitcoins that Chandler is sending to Joey.
- Chandler’s bitcoin address.(Chandler’s Public key)
All of this information is now sent over the network for verification along with an encrypted digital signature. Chandler’s bitcoin address and the amount he is sending to Joey are combined to create a hash value for the digital signature once more. The private key encrypts this digital signature. A miner that has to confirm this transaction receives this data and does two tasks at once:
- He takes all the un-encrypted data like transaction amount and public keys of both Joey and Chandler and feeds it to a hash algorithm to get a hash value which we shall call Hash1
- He takes the digital signature and decrypts it using chandler’s public key to get a hash value which we will call Hash2
If both Hash1 and Hash2 are the same then it means that this is a valid transaction.
Distributed Ledger and P2P Network
The ledger is accessible to everyone on the network. There isn’t a solitary central copy. Here’s an illustration to help you understand what a ledger is: Let’s say you need to transfer your friend John 10 Bitcoins, but you have 974.65 Bitcoins in your account and 37 in John’s. Your balance will be credited to John’s account after being reduced by 10 BTC.
Blockchain has a unique way to implement this. There are no accounts and balances in the Bitcoin Blockchain ledger. Every transaction from the first one is stored on a continuously growing database called Blockchain. There are blocks averaging around 2050 transactions and as of today, there are 484,000 blocks on the Blockchain with around 250 million transactions.
This ledger is distributed across all users of Bitcoin Blockchain, i.e., the ledger has no central location where it is stored. Everyone on the network owns a copy of the ledger and the true copy is the collection of all the distributed ledgers.
Proof Of Work
You might be wondering if everyone equally owns the ledger, who adds blocks to the Blockchain? How can people trust this person?
We have the idea of proof of work for this. In essence, it is similar to resolving a sizable puzzle. It involves a lot of computation. People in the Bitcoin network—also known as miners—perform this effort. These miners’ tasks include checking the transactions and resolving a challenging mathematical conundrum related to the block that is being built. The problem’s difficulty is changed so that, on average, a block can be solved in 10 minutes. A precise nonce (mathematical value) that produces the desired hash, which is preset, is what miners look for. To get the right hash, you must attempt around 20.6 quadrillion nonces at the present level of difficulty.
Each block has a hash value which is the combination of the previous block’s final hash, transaction data’s hash value, and the nonce. The final resulting hash for the block must start with a specified number of trailing zeroes. It is this computation to find the nonce which satisfies the condition that makes mining so computationally expensive.
So the person who finds this nonce is the successful miner and he/she can add their block to the blockchain. Through our P2P distributed network, he/she broadcasts their block and everyone verifies if hashes match, updates their blockchain, and moves on to solving the next block immediately.
Incentives for Validation
The last step of a Bitcoin transaction is to give a reward to the miner who has created the latest block. This reward is provided by the Blockchain system for validating the transactions and maintaining the Blockchain. Currently the reward per block is 12.5 BTC (Rs 3,427,850/- or $ 53,390). This is the most interesting part of Bitcoin Mining.
Bitcoin incentives are the only way to generate new currency into the system and it is believed that by 2140, all 21 million bitcoins will be mined.
I hope that after reading this, you have a better grasp of and appreciation for blockchain technology. Bitcoin is only a small part of the blockchain. Blockchain aims to upend numerous industries, including finance. Let’s continue with our blockchain tutorial by taking a closer look at one such instance, IBM and Maersk, to better understand how blockchain is changing the Supply Chain Industry.
A brief History of Blockchain
Blockchain technology was first described in 1991 by the research scientists Stuart Haber and W. Scott Stornetta. They wanted to introduce a computationally practical solution for time-stampeding digital documents so that they could not be backdated or tampered with. They developed a system using the concept of a cryptographically secured chain of blocks to store the time-stamped documents.
Merkle Trees, which were integrated into the design in 1992, increase the efficiency of the blockchain by enabling the collection of several documents into a single block. In order to build a “secured chain of blocks,” Merkle Trees are utilized. Each data record in the series that it stores is linked to the one before it. This chain’s most recent record includes the chain’s history. The patent for this technology expired in 2004 since it was never used.
In 2004, computer scientist and cryptographic activist Hal Finney introduced a system called Reusable Proof Of Work(RPoW) as a prototype for digital cash. It was a significant early step in the history of cryptocurrencies. The RPoW system worked by receiving a non-exchangeable or non-fungible Hashcash-based proof of work token in return, creating an RSA-signed token that could further be transferred from person to person.
RPoW solved the double-spending problem by keeping the ownership of tokens registered on a trusted server. This server was designed to allow users throughout the world to verify its correctness and integrity in real-time.
Additionally, Satoshi Nakamoto developed the principle of distributed blockchains in 2008. He makes a special improvement to the design that makes it possible to add blocks to the initial chain without needing them to be signed by reliable parties. The updated trees would include a safe record of data transfers. It timestamps and verifies each exchange via a peer-to-peer network. It might be run independently without a centralized authority. These advancements were so advantageous that they turned blockchain technology become the foundation of cryptocurrencies. In the cryptocurrency industry today, the design acts as the public ledger for all transactions.
The evolution of blockchain technology has been steady and promising. The words block and chain were used separately in Satoshi Nakamoto’s original paper but were eventually popularized as a single word, the Blockchain, by 2016. In recent times, the file size of cryptocurrency blockchain containing records of all transactions that occurred on the network has grown from 20 GB to 100 GB.
What Does a Blockchain Developer Do?
The wise yet short answer to this is: a Blockchain developer develops Blockchains! Well, that was easy!
Blockchain developers enable secure digital transactions by creating systems to record and store blockchain data in a way that prevents changes or hacks. They design secure blockchain technologies, develop application features and interfaces, and maintain client and server-side applications.
Types Of Blockchain Developers
1) Core blockchain developers
These are in process of developing and improving architecture. The developer will be in charge of designing, developing, and optimizing the protocols that will be used to enable a blockchain solution. The consensus protocol, for example, outlines how and in what manner users of the blockchain and the resources it contains agree on sharing and utilizing these resources.
- They also make decisions relating to such.
- They implement the functionality and features of the blockchain and ensure that they work as intended.
- They design and implement the security of the network.
- They ensure the network is operational.
- They plan, design, and implement integrations of the blockchain network with other services.

3) Back-end developers
These individuals may design and implement APIs, do performance tests, install blockchains, create software specifications, collaborate with other developers on software development, and give technical support.
4) Smart contract engineers
They audit and develop smart contracts, meet with users and buyers, understand business flows and security to ensure no flaws in smart contracts, and study smart contracts, do end-to-end testing of the business processes.
Why Become A Blockchain Developer
The following reasons will explain it better:
1) High demand
Cutting-edge technology and potential for growth: According to a PwC poll from last year, blockchain has a bright future, with 84 percent of organizations experimenting in the technology. Blockchain will be used by a far larger number of individuals. Only around 1% of businesses have adopted the technology, with many more considering it in the future.
2) Amazing pay
The average salary for a blockchain developer in the United States is between $150,000 and $175,000 per year. A developer’s compensation is one of the highest in the industry, according to this research. Experienced and highly qualified blockchain professionals get paid more.
3) Ability to teach others
Jobs and training as a blockchain developer might open up new revenue sources by teaching others how to work on the same platform. They can, for example, educate using online instructional platforms.
4) They get to understand crypto, ICOs, etc, and how they and their companies can raise capital using new revenue streams with crypto.
5) Improved digital identity and security
Blockchain has more promise for businesses looking to safeguard their operations and platforms than traditional non-blockchain platforms.
Blockchain platforms and processes such as digital identities also help cut down the process and operational costs for developers and their organizations.
6) Contribute to other new-age technologies
Blockchain integrates with other technologies such as IoT.
Roles of a Blockchain Developer
Let’s first discuss the roles of a core blockchain developer.
Core Blockchain Developer
As discussed earlier, a core blockchain developer is generally involved in the design, architecture, and security of a blockchain system. In brief, their roles include the following:
- Design of blockchain protocols
- Design of consensus protocols and security patterns for the network
- Design of the network architecture
- Supervision of the entire network
Blockchain Software Developer
Developers of blockchain software have their own set of responsibilities. These responsibilities have nothing to do with the system’s consensus design or architecture. Blockchain software developers create decentralized applications or Dapps using blockchain technology, just way a regular web developer uses the protocols and architectural structure set up by a core web architect to build web apps. Their responsibilities include:
- Development of Smart Contracts
- Development of interactive front-end designs for Dapps
- Backend development pertaining to Blockchain
- Supervision of the entire stack running their Dapps.
Now that, I’ve told you guys about the different types of blockchain developers and their respective roles, let me tell you guys about the technical knowledge and skills required for you to bootstrap your career as a blockchain developer.
Top Blockchain Developer Skills
Blockchain engineers, as you’ve already seen, have a lot of duties. They’ll need a few skills to be able to manage such responsibilities effectively. In order to be a good blockchain developer, certain skills must be developed and mastered. To face and manage blockchain development, you need have the following key blockchain developer abilities.
Cryptography is the study of protocols that prevent unwanted parties from accessing your data. There are many essential concepts in cryptography you should be familiar with as you’ll need them during blockchain development.
For example, public-key cryptography is a crucial topic of blockchain. It forms the basis for the transactions we make through cryptocurrencies.
To perform cryptocurrency transactions, you’ll need a wallet and the key to that wallet. That key is necessary because it establishes your ownership of the wallet. Cryptocurrency transactions are secured via the encryption and decryption of public and private keys.
Cryptographic hashing is another important idea in cryptography. Hashing is the process of obtaining a particular length output from an input of any length. The hash function might store information with 20 or 200 characters, but it will only return data of the length you choose.
Certainly, cryptography is vital for the proper workings of blockchain technology. You should learn about it and its various aspects, including the topics we’ve discussed here. With its knowledge, you’ll be able to keep your blockchain data safe.
2) Blockchain Architecture
You should be familiar with blockchain architecture if you want to work as a blockchain developer. You should understand what a blockchain ledger is, what consensus is, and how smart contracts function.
Blockchain architecture has three kinds; they are:
- Consortium architecture
The consortium’s design isn’t entirely decentralized. The members of a group have complete control in this situation. The group in these circumstances is made up of many organizations. The Energy Web Foundation is a great example of this sort of blockchain design.
- Private architecture
Only a few people are involved in a private blockchain architecture. It’s a widely used application in businesses. Sawtooth and Fabric are two well-known examples of this type of architecture. Another important characteristic of such design is that it is not decentralized.
- Public architecture
The most decentralized sort of blockchain architecture is public architecture. You may participate in the network by mining or conducting trades. Bitcoin is the most well-known example of public blockchain architecture, and you’ve probably heard of it.
You should read the whitepaper of bitcoin on blockchain to become familiar with this topic. It requires a little effort, but be sure that it’s worth it because you’ll get familiar with all the fundamentals and the advanced concepts altogether.
3) Smart Contracts
Smart contracts have been a common concept in the blockchain sector since the launch of Ethereum. Almost every blockchain solution seeks to profit from smart contracts. As you can see, this technology is quite strong.
Smart contracts allow two parties to exchange products or services without the need for a third party to serve as an intermediary. Smart contracts can be compared to vending machines. You make the payment, select the item you want, and receive the item along with the remaining change. There is no third party in this transaction; you and the vending machine are the only ones engaged.
Only when all of the parties involved have met both of their requirements do smart contracts come to an end. Because blockchain is decentralized, it is extremely effective. This means that hundreds of people are watching your smart contract, and because they function on an IF-Then basis, there’s a chance that something may go wrong.
You can use smart contracts in many areas of different industries, such as law, construction, and many others. It can remove the middlemen from contracts and help in saving money and resources.
To become a blockchain developer, you should make yourself familiar with smart contracts. It is one of the essential blockchain developer skills. Multiple languages specifically focus on smart contract development, such as Chaincode and Viper.
4) Data Structures
To work as a blockchain engineer, you’ll need a strong understanding of data structures. This is because blockchain engineers work with a variety of data formats on a daily basis since they must construct and implement networks.
The entire blockchain network is made up of data structures, as even a block is a type of data structure. A block clusters transactions for the public ledger because so it is a container data structure, whereas the public ledger is the blockchain.
A block also contains a header, and the former is around 10,000x larger than the latter. As you can see, data structures are the fundamental concept of blockchain. You’ll need to master this topic to understand blockchain technology effectively.
Learning about data structures can help you understand the fundamentals of blockchain. Having a solid foundation can help you grasp complex topics more quickly. You’ll be employing both of these technologies to create reliable, helpful, and secure solutions, as we’ve already discussed.
5) Web Development
As a blockchain developer, you’ll be developing web apps in most cases. Learning web development will make you acquainted with all of its aspects, and you can use this knowledge to create robust web apps that use blockchain technology.
You’ll need to study web design, app development, and programming, which will all help you create better Dapps. Because most companies want blockchain developers to design apps that users with little or limited knowledge of blockchain can use, web development is essential. Having a lot of design experience can help you a lot in this area.
6) Know the platforms
Choosing the right blockchain platform is a crucial test for the organizations today, due to a large number of systems regularly makes perplexity. Deep learning of diverse blockchain platforms comprising
Hyperledger Fabric, Ethereum, Ripple, and R3 Corda, all developed by the Linux Foundation, will be authorized to make a difference with the right use case for the right blockchain platform and well-spoken their distinctions.
7) Understand the blockchain security
For uniformity, legality, and administrative demands, security frameworks are still being developed. Public and private key cryptography, cryptographic hashing, Merkle confirmations, and elliptic bent digital signatures are all valuable security abilities.
Since blockchain isn’t a database technology, it requires a breadth and depth of capacities that each capable blockchain expert should secure as aptitudes. To be effective, you should get an understanding of blockchain standards and practices and how they can be connected inside your business condition.
7) Languages You Must Know
Blockchain development is vast. Apart from the topics we’ve discussed, you should also consider learning a few programming languages. A common question among beginners is, ‘What languages should I learn to become a blockchain developer?’
The following are the main languages you should learn as a part of your blockchain skills:
Java is popular among blockchain developers because of many qualities. It’s simple to understand, but it’s capable of producing a wide range of complex answers. Java is used to power NEM, a prominent cryptocurrency. Java has a developer community of more than 9 million people. Furthermore, it has been in the industry since 1995. Because data mastery is necessary for blockchain development, even if Java is old, it is still important.
C++ is a widely used language among blockchain programmers. With its assistance, you may complete a variety of blockchain-related activities. Because bitcoin core’s designers utilized C++, it’s a must-have for any prospective blockchain developer.
Python is among the most popular programming languages on the planet. It’s versatile, and its various libraries enable you to use it for both front-end as well as back-end development. That’s why you should make yourself familiar with Python as well.
Python has a significant community of more than 4 million developers. Such a thriving and supportive community can help you out with many problems and doubts.

This is a description of the economics of cryptocurrencies and how they’re implemented on the blockchain. Game theory, mathematical frameworks for modeling Cryptonomics, and modeling disputes may be taught in blockchain developer training and courses. Factors affecting Cryptonomics and associated monetary policies may also be taught to trainees.
7) Computer coding
Computer programming is essential for the development of any advanced and effective decentralized apps or dApps although in some cases you might be able to develop beginner dApps without this skill.
Most blockchain developers begin by studying a computer language or coding, then specialize in blockchain development using that knowledge. Most blockchain creation involves knowledge of common programming or coding languages, however other blockchains, such as Ethereum, require knowledge of a particular coding language.
Languages in which you need the expertise to develop for blockchain are C++, C#, Java, Python, Simplicity, and Solidity. Advanced development on blockchain may require more than one coding language.
The top blockchain platforms on which to target as a blockchain developer are Bitcoin, Ethereum, Hyperledger, Ripple, Spark Solidity, Stellar, Neo, and EOS.

What Kind of Mindset Do You Need to Become a Blockchain Developer?
Before we dive into those two different types of people aspiring to become Blockchain developers, it may help to familiarize ourselves with the kind of mindsets that are best suited for Blockchain developers. After all, the unique challenges of Blockchain development require a certain unique way of thinking.
When you hear the word “hacker” stated aloud, it’s typically not in a favorable light; no self-respecting company wants to do business with hackers (except ethical hackers, but that’s an another tale for another time). However, it is the hacker attitude that aids in the development of skilled Blockchain engineers. When presented with issues or hurdles, hackers are more likely to think outside the box than to think traditionally.
A skilled Blockchain developer may also work as part of a team and cooperate. On a similar note, the perfect Blockchain developer understands when to seek assistance with an issue and when to persevere until they find the solution.
So the best candidate for Blockchain development works well with others, knows his or her limitations, and can unconventionally approach problems.
