Blockchain uses a lot of data structures combined with advanced cryptography to build a secure and immutable system. Knowledge of blockchain, without any knowledge of data structure, can only be considered incomplete. Blockchain is a combination of advanced cryptographic and data structures, so it is clear that you also need to have a good grasp of cryptography. Lots of cryptographic methods, like hash functions SHA and KECCAK, are used in blockchain in addition to asynchronous cryptography to generate digital signatures.
Without understanding how these things work, it is impossible to become a blockchain developer. Blockchain is a combination of advanced cryptographic and data structures. Smart contracts have become a huge thing since Ethereum was launched. Every blockchain now tries to incorporate smart contract functionality into its system. Smart contracts enable business logic to become appliable to the blockchain. Therefore, developers trying to get into the blockchain field should definitely learn about smart contract development.
This usually requires learning network-specific languages like Solidity, Viper, Chaincode, etc. If the prospect of joining the ground floor of this exciting innovation appeals to you, then you might be wondering what the next step is. For every year blockchain developer job in the industry, only one blockchain developer is eligible. Many asset companies like IBM, Accenture, and Capgemini are on the hunt for qualified blockchain developers.
In Vietnam, blockchain development companies are thriving and competing with other markets around the world. Bacoor Inc. The company has a strong development team in Vietnam. Their outstanding products are HB Wallet and recently, Pantograph. This would be an ideal suggestion if you are looking for a blockchain company.

Now that completes the first milestone. How can you possibly innovate and improve upon a platform when you have not used it even once? Go to Coinbase or any other exchange that you are comfortable with or is accessible in your country and buy some coins. It is extremely straightforward. Since you are not going to be buying a lot of coins then simply use a basic online wallet. These wallets are the easiest to use among all.
Furthermore, you can access this wallet from any server or any device in the world as long as it is connected to the net. Having said that, there is one big problem when it comes to online wallets. Your private key is going to be saved on another server.
This is basically like serving up your key to hackers on a silver platter. Do NOT use online wallets to store huge amounts of your money. Store the bare minimum that you need for exchange purposes. As you create an extensive portfolio, you must learn how to utilize cold wallets to store your money.
You can learn how to do so here. As a blockchain developer, you will face tons of challenges in the back-end. Creating and maintaining a public blockchain is not easy because of a number of reasons. Blockchains, as David Schwartz puts it, should be fortresses. Firstly, the code is public and open for all to see. Anyone can look at the code and check for bugs and vulnerabilities. However, unlike other open code resources, the downside of finding vulnerabilities on blockchain code is massive.
Any programmer can hack in and get away with potentially millions and millions of dollars. Because of these legitimate security concerns, development on the blockchain is usually very slow. It is important to keep pace with the network. You cannot fall too far behind and not keep up with all the network demands. You should be well equipped to handle remote and local queries.
The blockchain must always perform at its highest possible capabilities, but for that to happen the language chosen must be extremely versatile. All that you need for signature verification is the key, transaction, and signature. With just three data you can conduct verifications in a parallelized manner.
However, not all the functions on a blockchain should be done that way. Think of transaction execution itself. Some languages are good at parallel operations while some are good in non-parallel operations. That is called deterministic behavior. So, in blockchain development, all transaction operations must be deterministic.
You cannot have a transaction that behaves one way and then behaves another way the next day. Similarly, you cannot have smart contracts that work in two different ways on two different machines. The only solution to this is isolation. Basically, you isolate your smart contracts and transactions from non-deterministic elements.
There are some languages that fulfill most of these needs. Javascript is usually used to create highly interactive web pages. How do we make a block? What does a simple block consist of? Before we continue. You need to understand certain terms that we are going to use in our program:. Ok, so this right here is out a block.
So, in the first line of the code, we called the crypto-js library because the sha hash function is not available in JavaScript. Next, we invoked a constructor inside the class to call for objects which will have certain values. It is the foundation of blockchain.
The bitcoin blockchain integrates public-key cryptography to create digital signatures and hash functions. Therefore, having a better grasp of cryptography could be advantageous to become a blockchain developer. Many cryptographic methods like hash functions, e. Blockchain and smart contracts have been an intriguing subject over the past few years. Since the release of Ethereum smart contracts has become a huge thing.

Who We Are
Since the day Ethereum entered the market, smart contracts have become a popular term in the blockchain industry. Almost every blockchain solution wants to use smart contracts for their benefit. So you can see how powerful this technology is. Smart contracts let two parties exchange goods or services without needing an intermediary. You can compare smart contracts with a vending machine. You put in the payment, choose the product you want, get the product along with the remaining change.
Smart contracts finish only when the involved parties fulfill both of their conditions. 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.
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,x larger than the latter. As you can see, data structures are the fundamental concept of blockchain. Learning about data structures will ensure that you know the basics of blockchain.
Having a strong foundation helps you in understanding the advanced concepts more quickly. To become a blockchain developer, you should be familiar with blockchain architecture. You should know what a ledger means in blockchain, what is consensus, and how smart contracts work. Here, the members of a group have full authority. In these cases, the group is made up of multiple organizations. The Energy Web Foundation is a stellar example of such blockchain architecture types.
In a private blockchain architecture, only a few people are part of the system. Sawtooth and Fabric are famous examples of such architecture. Another essential quality of such architecture is that they are not decentralized. Public architecture is the most decentralized type of blockchain architecture.
What skills do I need to become a blockchain developer? May 1, Here are the minimum qualifications to score yourself a job as a blockchain developer: Basics of Blockchain. Cryptography, Decentralization and Consensus Protocols.
From private and public keys to digital signature, proof of work, and proof of stake, you should understand cryptography and blockchain consensus. Cryptocurrency Wallets, Transactions and Exchanges. You should know how to build a wallet, wallet APIs, generate keys, use mnemonics and send transactions.
Cryptocurrency Mining. Qualified engineers need an understanding of the mining process, including core mining, mining software, mining pools and mining hardware and software. Ethereum and Crypto-tokens. The Ethereum blockchain offers a standardized way to create new tokens on its blockchain called the ERC20 protocol. Optimizing a Blockchain Network. NodeJS enables developers to write server-side applications with Javascript.
The breadth of frameworks which run on NodeJS allows any form of application to be created and deployed on top of Node. Many Blockchain frameworks are built on top of NodeJS.
Each of these blocks of data i. What is Blockchain? How does it work? What are the consensus mechanisms? What is a node? What is a Smart Contract? Understanding the basic answers to these questions is vital to creating useful Blockchain applications.
These are the skills needed to start developing solutions on the Blockchain, and more specifically the Ethereum ecosystem.
It is used for implementing smart contracts on various blockchain platforms, most notably, Ethereum. Smart Contracts are immutable. An immutable object is an object whose state cannot be modified after it is created. Instead of incrementally improving your Smart Contract with new releases, once a Smart Contract is deployed it cannot be changed. Think of a Smart Contract as a monument designed to stand the test of time.
Smart Contracts hold Ether just as any other address wallet does. It can send and receive Ether value to and from other addresses also.
By creating a Smart Contract you are deploying a set of rules to the network by which anyone who chooses to use it is willing to abide by. So successfully hacking it technically means that the rules were still followed, they were just bad rules.

Their apps run on the blockchain too. You can compare them with web developers, who use the products of a web architect protocol and design to develop web applications. Blockchain software developers create Dapps or decentralized applications. They are responsible for the front-end as well as back-end development of Dapps. They also supervise the stack that runs the Dapps.
These developers focus on the architecture development of a blockchain system. They design their consensus protocol and make most of the vital decisions related to blockchain. They supervise the network and design the architecture of the same. Core blockchain developers are responsible for the security of their blockchain network as well. To handle those responsibilities well, they need to possess a few skills as well.
Here are the primary blockchain developer skills you should have to become one:. Cryptography is the study of protocols that prevent unwanted parties from accessing your data. For example, public-key cryptography is a crucial topic of blockchain.
It forms the basis for the transactions we make through cryptocurrencies. Save transactions of cryptocurrencies take place through encryption and decryption of public and private keys. Another essential concept of Cryptography is cryptographic hashing. Hashing refers to producing an output of a specific length from an input of any length.
Certainly, cryptography is vital for the proper workings of blockchain technology. Since the day Ethereum entered the market, smart contracts have become a popular term in the blockchain industry.
Almost every blockchain solution wants to use smart contracts for their benefit. So you can see how powerful this technology is. Smart contracts let two parties exchange goods or services without needing an intermediary. You can compare smart contracts with a vending machine.

Many companies build teams around blockchain technology, from start-ups to banks to IT players. A consensus was formed that one could adapt to different processes, beyond the virtual currency field, the largely distributed newspaper that was set up to authenticate bitcoin payments. As companies, and even governments, became interested in the potential of technology-based systems, the blockchain, the demand for expertise to create pilot projects and launch products has grown rapidly.
The demand for skills apparently comes from different sectors of activity. Some are more advanced than others in their blockchain strategy. Banking groups such as UK-based Barclays, which is particularly active in this field, BBVA and Santander in Spain, and UBS in Switzerland, have been studying the potential of the technology for some time now, while others have just begun to test the temperature.
Dutch bank ABN Amro recently announced that it is a team of about 30 people to explore the use of technology. In France, the Banque de France itself launched an experiment with two start-ups.
In a general way, all the actors of the finance are interested from near or far. Visa and Thomson Reuters are also looking for specialists, while in another field; Airbnb has recruited this year a team of experts blockchain and bitcoin.
Start-ups in this niche are numerous, from those that provide the basic building blocks of technology, such as Ethereum and Eris, to those specializing in enterprise applications, including Everledger. We also see companies like R3, based in New York, looking to create blockchain standards for the financial sector.
Finally, all major consulting companies are in the process of building blockchain teams to support their customers on what could become an important transformation technology. In this area, Deloitte acquired the Rubix start-up and the firm has just announced the creation of a European center of excellence in Dublin to support its customers in the financial industry in the discovery of use cases and go to the development of solutions.
In France, its subsidiary will rely on this center which will bring together 50 employees, developers and designers over the next 18 months to meet the needs of the French market. For its part, PwC has seized Bitnet and Capgemini plans to bring together a hundred specialists by the end of the year. KPMG is also recruiting. The posts open around blockchain by companies are of various natures. Some involve experts with experience in the creation and operation of distributed ledger systems in production.
But larger companies will more often seek to build a team around a core of blockchain experts. In this case, all they need in addition to strong skills in software development and engineering is a very good understanding of the principles around technology.
Of course, blockchain is just one of the components of a typical technology stack. Engineers who specialize in network or security, for example, play a vital role alongside those who bring basic software development skills.
Knowledge of rapidly developing technological tools such as Docker containers and micro-service architectures will also be a plus. For Nick Williamson, of Credits,. That said, some specific skills will be welcome. The latter are generally agnostic on the technology stack and require above all strong programming skills, according to Zeth Couceiro, Opus IT recruitment firm. Essentially it could be used to record anything of value! Many startups are now using blockchain technology in myriad ways, from global payments, to music sharing, and even tracking diamond sales.
This has created numerous opportunities for blockchain engineers. There are a couple of paths you can go down as a blockchain engineer. In simple terms, you can:. The above graph shows that the number of job opportunities in the blockchain domain has increased from 0 to just under between and We asked them three key questions to help you navigate your way through this complex and nascent field.
