Blockchain technology is expected to completely change the digital world processing data and the way to develop business. The blockchain shows a certain degree of multifunctional and security, which has attracted the attention of many enterprises and government departments and began to use it. This is a career with great development potential. It is characterized by new dynamic new technologies that have just started, then you should consider becoming a blockchain developer, which makes sense. In this article, we will introduce how to learn from scratch as a blockchain developer.

What is blockchain?

Blockchain is a digital classification account for all cryptocurrency transactions in all peers. This blockchain technology is different from any other traditional trading methods that are concentrated and controlled by some governments and groups. But this blockchain is decentralized, which means that it is not controlled by any single entity or group.

This technology benefits more companies around the world because blockchain technology allows companies to conduct security transactions without involving third parties. Network nodes verify transactions and record them in open classification accounts called blockchain. Each node in the network is constantly updated and saved the blockchain. This is why blockchain technology is particularly known for its security, because once data is recorded on the blockchain, it is difficult to be tampered with. In addition, the encrypted distribution makes it almost impossible to change the data without detecting the data.

What is blockchain development?

Blockchain development is a process of development and maintenance of the blockchain platform. This involves the creation of infrastructure that allows the creation and management of blockchain -based applications and services, such as digital currencies, smart contracts, and distributed applications. It also involves the development of tools and technologies that support the platform.

Blockchain applications are just a program or platform that uses blockchain special and advantages (such as security, transparency, and reliability). Blockchain development is a complex process that needs to have an in -depth understanding of underlying technology. It also needs a firm commitment to safety and scalability. Development blockchain platform is a major task that requires a lot of resources and professional knowledge.

What exactly do blockchain developers do?

Blockchain developers programmed, developed and tested blockchain software and systems.

Core blockchain developers: they develop and maintain the architecture of the blockchain system. They develop agreements and security models and maintain the entire network.

Blockchain software developers: They build blockchain applications on existing blockchain platforms. They handle the development, maintenance and failure of these applications.

Back -end developers: They can design and develop APIs, perform performance testing, perform blockchain deployment, design software specifications, develop software with other developers, and provide technical support.

Intelligent contract engineers: They review and develop smart contracts, meet with users and buyers to understand business processes and security to ensure that smart contracts have no defects, and study smart contracts, and carry out business processes.

How to become a blockchain developer?

Therefore, after all these, the problem itself appears: to bear all these responsibilities, how to train people who have necessary skills, and let them meet the challenges of blockchain development? There are two different situations here. Some blockchain hoping people start from the beginning without any programming background. Some people's professional experience is similar to the blockchain.

What do you need to learn to become a blockchain developer?

1. Start from academics

First, it is recommended that you have the academic background in the field of computer science/information technology. You can choose to get a bachelor's or master's degree in a specific stream.

Data structure: In addition to programming language, you also need to master the concept of data structure. Blockchain developers use data structures to develop unable and efficient systems. You need to thoroughly understand various data structures, such as linked lists, binary trees, heaps, scatters, pictures, and so on.

Database and network: In addition, you also need to have some basic knowledge of database and network concepts to start your blockchain developer journey. It will help you understand the mechanism of distributed systems and other important concepts of blockchain development.

Cryptology: Cryptology is one of the necessary technical skills for blockchain developers. You need to understand the concepts of various cryptography, such as digital signatures, hash functions, RSA algorithms, etc., laying the foundation for your blockchain development.

In addition, in addition to these technical skills, you also need to be familiar with the web design and development process, because it is one of the core aspects of blockchain development, and will help you in developing DAPPS and processing API.

3. Understand the basic knowledge of the blockchain

Once you master the necessary technical skills, now you need to understand the basic knowledge of blockchain technology. You need to learn more about blockchain technology, such as its working principles, applications, etc. You need to have a full understanding of the blockchain architecture, and understand the concepts of consensus, hash functions, distributed ledger technology. In addition, you need to understand Bitcoin and other important concepts, such as public and personal methods, decentralization, and many. You can choose a variety of online and offline resources, such as tutorials, journals, training and conferences to clearly understand blockchain technology.

4. Understand password economics

Now let us turn to another key aspect of blockchain development -cryptography! Intersection The word "cryptography" is produced by combining these two terms -cryptography and economics. It involves the process of understanding the economic concepts and methods behind cryptocurrencies. You need to learn about various important concepts, such as trading costs, mining, trading life cycle of Bitcoin, etc., to cover cryptographic economics courses. However, cryptocurrencies are only a small part of the entire blockchain technology. You need to understand the mechanism in detail to understand the basic knowledge of the blockchain.

5. Understand Ethereum and dapps

This is one of the most prominent parts of blockchain development -Ethereum. Ethereum is an open source and decentralized blockchain network that is used to run smart protocols and allow the development of smart contracts and distributed applications (DAPP) without any common problems such as shutdown, fraud, and third -party interference. At the same time, decentralized applications are software systems developed on blockchain platforms such as Ethereum. In addition, there are several other well -known platforms and EOS, Hyperledger, etc. can be considered for blockchain, but because of its various functions, it is recommended that you use Ethereum to start your journey.

6. Understand smart contracts and solidity

Let us study the blockchain field more and understand other necessary concepts, such as smart contracts, solidity, etc. When it comes to smart contracts, it is related to the protocol or instructions for automation purposes, without any third party intervention in the transaction incident. Intelligent contracts work on three major components -definitability, endability and isolation. In addition, Solidity is a static type of high -level language for writing smart contracts, which is mainly influenced by JavaScript.
