What is blockchain technology?
Construction of the Metaverse starts with a single block, like a house in real life.

Blockchain technology is a structure of computers that is used for transactional records. The data is stored in several databases and can be accessed when needed. It is usually decentralized and utilized for digital assets.
Blockchain technology is one of the most sophisticated human developments that has made human life much easier as it brought with it some impossible things. An example of its benefits is protection from Byzantine fault, protecting data loss even if multiple computers in the system lose data. It changed the transactions pattern as there is no more need for third parties to mediate two parties in transactions.
Blockchain is defined as a shared, immutable ledger that processes and records transactions. Blockchain technology is important for us because it serves various purposes. It has found many uses in multiple industries and thus can’t be outrightly shrugged off. Here is a brief overview of the blockchain system’s emergence, features, and benefits.
The Emergence of Blockchain
Blockchain technology is the result of the attempts made to develop a decentralized system that is trustless and doesn’t require human intervention to ensure fair play. The initial origins of this can be traced back to the early 90s. Initially, it was envisioned as a cryptographically secured chain of blocks. These blocks contained data and couldn’t be tampered with.
The development continued till 2008 when Satoshi Nakamoto gave the modern, sophisticated form of blockchain. It began to become relevant because of the various uses it found. Bitcoin was the first real-life use case of blockchain technology, and since then, it has found various other uses
The first whitepaper regarding blockchain technology was released in 2009. It gave the complete details of how this technology is beneficial and how it can be used. It can be used in fields like cross-border payments, secure sharing of confidential data, supply chain, etc.
Features of Blockchain Technology
Blockchain technology has some basic features that set it apart from other technologies. These basic features are given as follows.
Immutable
A blockchain system is immutable as it records all the transactions taking place. The transaction data is stored on the system and remains there. There is no option available to erase the data, so the record remains there. Thus, it reduces the chances of fraud and data tampering.
Decentralised
A blockchain system is decentralized as there is no central controlling authority. In contrast, the system is controlled by the collective voting of the members of the blockchain system. The absence of a central controlling authority ensures that there are no unfair decisions and the whole group of members decide what should be done in a specific situation. The said feature gives the members freedom to keep hold of their assets on the blockchain system.
Security
The security of the blockchain system is foolproof because of the absence of a central authority. Cryptography is the main reason that the data on the blockchain system is secure as no one else other than the authorized owner can access a specific asset. It is a complex set of algorithms that can’t be broken and keeps the data on the blockchain secure.
There is a unique identification key that is used to decrypt data. The data owner has this key which keeps the data accessible to that person. If the person doesn’t share the key, no one will be able to access that data.
Distributed Ledgers
The open blockchain system is public, and the reason for it is the distributed data over various nodes that make up the blockchain system. The data regarding the progress of a transaction is stored on the blockchain system. The distributed ledges enhance the reliability and safety of the data. There are few chances that the data would be lost.
Consensus
There are consensus algorithms in the blockchain system that keep the system working smoothly. The result is in the form of collective decisions that would keep the system benefitting the members.
Final Settlement
In contrast to the traditional banking system, blockchain systems are faster and settle the transactions in much less time. It saves the user time.
Benefits of Blockchain Technology
There are various benefits of using blockchain technology. Some of them are given as follows.
Trust
The blockchain system is trustless as it doesn’t require any mediators. The result is in the form of user trust. There are lesser chances that the users would be frauded because of scam transactions. Instead, there is a proper mechanism to ensure fair play.
Decentralisation
Decentralised blockchain systems are not governed by a single person, and no single person can affect the whole system. For this reason, decentralisation keeps the system democratic, and every member has a say in the decisions. The decentralisation of the system ensures that there is no foul play. An example is Bitcoin which runs using the same decentralisation feature.
Reduced Costs
The costs in the blockchain system are lower in comparison to other systems. The transactions in the traditional banking system take much time and effort. The blockchain system keeps the costs much lower while in comparison banks take much time and cost.
Speed
The speed of the transaction is much faster in comparison to traditional systems. If you need to transfer, money, etc., you won’t have to wait for long periods. Instead, the transaction will take much less time.
Visibility and Traceability
The transaction process is transparent as the whole system keeps track of the transactions. Thus, the chances of fraud or scams are lowered. No user can affect a transaction for their benefit. Along with that, the record of transactions keeps the system reliable.
Final Thoughts
The blockchain system has data transfer and other forms of transactions. The main reason for it is this system’s security, reliability, and decentralised nature. They have found various uses in the modern world as developers work on their uses in real life. As Web3 technology develops, it will get a further mainstream role.
