Understanding Blockchain Technology
Blockchain is a method of securely recording and storing information that prevents unauthorized changes, hacking, or manipulation. It functions as a distributed ledger, where transactions are duplicated and spread across a network of participating computers.
The technology behind blockchain involves a structure that stores transactional records, also known as blocks, in multiple databases called the “chain.” These databases are interconnected through peer-to-peer nodes, creating a network. This arrangement is often referred to as a “digital ledger.”
Each transaction in this ledger is verified and authorized using the owner’s digital signature, ensuring its authenticity and protection against tampering. As a result, the information contained within the digital ledger is highly secure.
In simpler terms, the digital ledger can be compared to a shared Google spreadsheet among multiple computers in a network, where records of actual purchases are stored. The intriguing aspect is that anyone can view the data, but they cannot manipulate it.

Reason Why Blockchain is Popular
In the case of sending money from your bank account to family or friends, you need to log into your online banking platform and provide the recipient’s account number to initiate the transfer. Your bank updates its records accordingly once the transaction is completed. The process may seem simple at first, but there is always a potential issue to be aware of.
Transactions of this nature are susceptible to tampering. Those aware of this vulnerability tend to exercise caution when using such transaction methods, leading to the emergence of third-party payment applications in recent years. However, Blockchain technology was specifically developed to address this vulnerability.
Blockchain is a digital ledger that has garnered significant attention and widespread popularity in recent times. But what factors have contributed to its widespread adoption? Let us explore the concept to gain a deeper understanding.
Efficient management of data and transaction records is crucial for any business. Usually, this data is managed internally or placed in the care of external entities such as brokers, bankers, or legal professionals. However, such approaches often result in increased time and costs for the business. Fortunately, Blockchain eliminates the need for these lengthy processes and enables faster transaction processing, saving time and cost.
Many people mistakenly believe Blockchain and Bitcoin are interchangeable, but this is inaccurate. While Blockchain is a technology capable of supporting various applications across multiple industries, such as finance, supply chain, and manufacturing, Bitcoin is a cryptocurrency that relies on Blockchain technology for its security.
Blockchain is an emerging technology that offers numerous advantages in our increasingly digital society:
1. Enhanced Security:
By utilizing a digital signature feature, Blockchain ensures transactions are conducted without the risk of fraud. This technology makes it virtually impossible for other users to manipulate or modify an individual’s data without a specific digital signature.
2. Decentralized System:
Unlike traditional methods where transactions require approval from regulatory authorities like governments or banks, Blockchain enables transactions to be carried out through mutual consensus among users. This results in smoother, safer, and faster transactions.
3. Automation Capability:
Blockchain is programmable and possesses the ability to automatically execute systematic actions, events, and payments once specific trigger criteria are met. This automation feature enhances efficiency and streamlines processes.
How Does Blockchain Technology Operate?
In recent times, the integration of Blockchain technology into numerous global businesses has become apparent. However, it is crucial to understand the inner workings of this technology. Is it a significant transformation or merely an additional feature? The potential of Blockchain is still in its early stages and holds the promise of being revolutionary in the future. Let us now delve into unraveling this technology.
Blockchain encompasses three key components:
1. Cryptographic keys:
These are private and public keys. These keys play a vital role in facilitating secure transactions between two parties. Each individual possesses both keys, which are utilized to establish a secure digital identity. This secure identity, known as a “digital signature” in the realm of cryptocurrencies, serves the purpose of authorizing and governing transactions.
2. Peer-to-peer network with a shared ledger:
The digital signature is combined with a network of individuals who serve as authorities. They employ the digital signature to reach a consensus on transactions and other matters. By undergoing mathematical verification, authorized transactions are securely validated, facilitating successful exchanges between the two connected parties. In summary, Blockchain users utilize cryptographic keys to engage in various digital interactions within the peer-to-peer network.
3. Computing mechanism for storing transactions and records:
The Blockchain network employs a means of computation to store and manage the extensive array of transactions and records. This component ensures the integrity and transparency of the shared ledger, reinforcing the overall security and reliability of the Blockchain system.
Different Types of Blockchain
There are different types of blockchain and they are as follows:
1. Private Blockchain Networks:
Private blockchains operate within closed networks and are particularly suitable for private businesses and organizations. They allow customization of accessibility, authorization preferences, security options, and network parameters. Only a single authority manages a private blockchain network.
2. Public Blockchain Networks:
Public blockchains, such as Bitcoin, were instrumental in popularizing distributed ledger technology (DLT) and cryptocurrencies. They address challenges like security vulnerabilities and centralization. In public blockchains, data is distributed across a peer-to-peer network instead of being stored in a single location. Verifying information authenticity relies on consensus algorithms, with proof of stake (PoS) and proof of work (PoW) being commonly used methods.
3. Permissioned Blockchain Networks
Also referred to as hybrid blockchains, permissioned blockchain networks are private blockchains that grant special access to authorized individuals. Organizations employ this type of blockchain to leverage the advantages of both private and public blockchains. It provides a structured approach to determine who can participate in the network and engage in transactions.
4. Consortium Blockchains:
Consortium blockchains possess elements of both public and private blockchains, but multiple organizations jointly manage a single consortium blockchain network. Although setting up consortium blockchains can initially be complex, they offer enhanced security once operational. Furthermore, consortium blockchains facilitate collaboration among multiple organizations.
5. Hybrid Blockchains:
Hybrid blockchains combine features of public and private blockchains. In a hybrid blockchain, certain parts are public and transparent, while others are private and accessible only to authorized participants. This makes hybrid blockchains suitable for situations where a balance between transparency and privacy is required. For instance, in supply chain management, multiple parties can access certain information while keeping sensitive data private.
6. Sidechain Blockchains:
Sidechains are independent blockchains that run alongside the main blockchain, providing additional functionality and scalability. Developers can experiment with new features and applications on sidechains without compromising the integrity of the main blockchain. They enable the creation of decentralized applications and the implementation of specific consensus mechanisms. Sidechains also alleviate congestion and enhance scalability by processing transactions separate from the main blockchain.
7. Blockchain Layers:
Blockchain layers involve building multiple layers of blockchains on top of one another. Each layer has its own consensus mechanism, rules, and functionality and can interact with other layers. This approach ensures greater scalability, as transactions can be processed concurrently across different layers. The Lightning Network, which operates as a second-layer solution on top of the Bitcoin blockchain, exemplifies this concept by facilitating faster and more cost-effective transactions through the creation of payment channels between users.
