What Is Blockchain?
To start understanding the fundamentals of blockchain development, it is necessary to understand what blockchain technology is. For this purpose, I want you to open the doors of imagination and imagine the scenario I will create. Imagine that there is an animated world where multiple blocks are living. These blocks are present to connect to each other and form a chain, hence, blockchain. But are you thinking about what these blocks consist of? Or how can technological advancement be this simple and boring? Well, the next part of imagination is to consider that these blocks are initially empty, but as soon as essential user data is filled in them, they are ready to get paired with other blocks to form the chain.
Back to technical terminologies, blockchain technology is defined as a digital database or ledger used to record users’ data. It was first launched in 1990 but gained popularity in 2008 by Satoshi Nakamoto. The concept gained attention with the rise of cryptocurrencies in the market. Reports have highlighted that more than 22,932 cryptocurrencies are all built on blockchain technology. Some of the key points in understanding the process are:
- The data in blockchain technology is recorded using cryptography, a process that does not directly save the user’s data. Instead, it uses digital codes so only the user can understand them.
- A centralized authority like the Government or any other specific institute does not control the data records of a blockchain network. Instead, blockchain networking is controlled by decentralization authorities, meaning a copy of the data record is accessible to all users around the world, which assures security and lessens the chances of hacking or data breaching.
- Unlike the traditional mode of recording data on spreadsheets manually, blockchain technology is more accessible and easier to handle as blockchain software handles the task of data recording and digitally storing the data on every computer or node used in the world.
- Blockchain technology has facilitated the process of digital transactions by making the process secure, effective, and efficient, as it does not allow the interference of a third party in the process.
What Is Blockchain Development?
It is essential to understand the blockchain development process to proceed further in the article. For starters, we will look at the elements of blockchain technology. Blockchain development consists of three essential elements.
Cryptographic keys, as explained before, are the codes used to enter and record user information. Since blockchain development is a decentralized platform, it is crucial to assure the data security of users, and cryptographic keys are one way of doing it. There are two kinds of keys, private and public. Each blockchain user or node has access to both types of keys to create a digital signature that works as the identity verification symbol of the user in the network.
A Peer-To-Peer Network
What makes blockchain development an exciting process is the feature of a peer-to-peer network all around the globe. The transactions that are held through the blockchain networks are authorized and verified by all peers existing in the network, creating a sense of mutual consensus and eliminating the chances of illegal transactions and hacking.
A Digital Ledger
The last element, which is also something that describes blockchain technology, is a digital ledger. The data record of users, transactions, and other essential sorts of data is stored in this digital ledger. This digital ledger is available to all nodes and individuals of the system. The data on the digital ledger can not be edited or accessed without the authorization of the users.
The Benefits Of Blockchain Technology
As vast as the world of blockchain technology is, it indeed delivers many benefits to the system’s users. Before moving on to how to become a blockchain developer, we will review some of the benefits of blockchain networking and technology.
Elimination Of A Third-Party For Transactions
Most third parties or banks charge a fee from users at the time of transaction. The first benefit of blockchain technology is that it eliminates the need for a third party to successfully complete transactions, eliminating the need to pay a fee or extra money. Another benefit of getting rid of these parties is that there is always doubt and fear of your assets and information being hacked or stolen. With a digital system that has so many features of user verification and security, users can easily trust the system.
Elimination Of Errors
As blockchain technology is an entirely led digital system with updated software and features, it eliminates the chances of manufactured errors. It promotes a secure system of transactions and data recording.
Makes Transactions Efficient
Traditional modes of transactions are less efficient than blockchain transactions. It takes plenty of days for a transaction to successfully complete if done by banks or other systems. But with the blockchain system, the decentralized feature of the technology enables the transaction process to take place in no time as multiple networks are connected simultaneously. This also helps in cross-border trade.
Assures User Security
The first and foremost priority of any tech advancement is to assure user safety and security. Users need to have a sense of safety in order to trust the process and share their personal records. Blockchain developers have understood this necessity and have taken multiple measures to assure user security. For instance, the feature of decentralization, cryptography, access to the digital ledger on multiple computer networks, transparency, and private transactions strengthen the security feature of the system.
Means Of Saving Valuable Assets
There is a misconception regarding blockchain technology that only data related to money and transactions are saved in the blockchain network. Well, this is not true. Users utilize the data-saving feature of the technology to record important bank details, documents, health records, identity management records, etc. In short, blockchain technology enables its users to save all sorts of data securely.
