From the first time we encountered Blockchain Technology, we have been trying to find ways to maintain its authenticity and avoid tampering. We invented different methods to achieve these objectives, such as watermarks, user permissions, and encryption algorithms. However, with the emergence of DLT (Distributed Ledger Technology), another way of storing data has emerged. The blockchain is a decentralized ledger that stores information in blocks; it is essentially a chain of blocks that cannot be tampered with or modified without changing all subsequent blocks. Each block in the chain contains information about the previous block along with transaction details or any other data. So what exactly is blockchain technology? Let’s take a look…

What Is Blockchain Technology?
Blockchain is a distributed ledger technology. It is a permanent, open, and public record of data that is tamper-proof and cannot be altered. A blockchain is a digitized, decentralized, public ledger of cryptocurrency transactions.Anyone can participate in the network by deploying a blockchain or distributed ledger network that communicates and validates transactions. The blockchain is used to store data that is financial in nature, such as cryptocurrency trades. It can also be used to store other non-financial data, such as a contract or a list of items. The blockchain is like a highly encrypted and verified shared Google document. Let’s look at blockchain further. A blockchain is a chain of digital blocks that are linked together creating a chain. The blocks are created and linked by cryptography, hence the name blockchain. A blockchain can be seen as a single and public digital ledger that records the transactions across a network of computers. It is programmed to record the creation of new blocks, the network addresses of other blocks, and when they are updated or changed.
How Does Blockchain Work?
A blockchain is a decentralised network that has no central authority. It is a chain of computers that are linked together with a shared mission or objective. These computers are called nodes. A blockchain is a digitized and decentralized public ledger of transactions that can be controlled and monitored by no one person or entity. The blockchain works on three main principles: – Distributed network: A network where the ledger of transactions is distributed among various computers around the globe. These computers are linked with one another to form a network. This can also be referred to as a peer-to-peer network. – Cryptography: A system of putting information into coded language so that only the person who has the key can read it. – Validators: People who confirm that the transaction has taken place.
Benefits of Blockchain Technology
– Trustworthy: The data in the blockchain ledger can be trusted as it has been validated by a network of computers. – Secured: Transactions are verified by all the computers in the blockchain network. Therefore, the ledger cannot be altered or tampered with. – Reduced risk: Data is unique and validated so there is low probability that it will be duplicated or faked; this reduces the risk of fraud. – Reduced Cost: There is no need for an intermediary as the ledger is decentralized and public. – Accuracy: Since all the computers have validated the data, the transaction details are accurate and correct. – High Availability: The network is distributed across the globe, ensuring that all computers are equally accessible. The system is designed to be fail-safe and has automated backup systems. – Speed: The blockchain can process transactions at a much faster rate than the traditional system.
Disadvantages of Blockchain Technology
– Data Insecurity: The data in the blockchains is not encrypted. So, if one has access to the ledger, they can alter it. – Security Concerns: A hacker can infiltrate the network and disrupt the functioning of the blockchain by altering the data. – Scalability Concerns: The blockchain technology is not scalable. Therefore, if the demand for the transactions increases, it becomes difficult to manage the system. – No Central Authority: The absence of a central authority makes it difficult to implement regulations. This may create an environment that encourages money laundering and fraud. – Inadequate Legal Framework: The blockchain technology is still in its nascent stages, and there is no legal framework governing it. This can create uncertainty in the minds of the users.
Conclusion
The blockchain technology is one of the most exciting and innovative technologies in the present day. It is relatively new, and its potential has not been fully explored. The blockchain technology can be used in multiple industries to create a robust and secure system. The blockchain is a decentralized ledger that stores data in blocks. It is a chain of blocks that cannot be tampered with or modified without changing all subsequent blocks. Each block in the chain contains information about the previous block along with transaction details or any other data. Although the blockchain technology is innovative, it can also be risky. The data in the blockchain is not encrypted, which means that anyone who has access to it can change it.
