Unlocking the Basics of Blockchain Technology

    Blockchain has brought a complete revolution in database technology. It has created a decentralized and transparent system that enables the safe recording and tracking of corporate transactions, assets, and records.

    It runs on an interchangeable shared ledger shared only among authorized people. This state-of-the-art database technology has brought a paradigm shift as blockchain platforms have changed how organizations function by giving real-time and accurate information, lowering risks, lowering costs, and creating new efficiencies and possibilities.

    What is Blockchain?

    Blockchain technology is a secure decentralized ledger that allows selecting people to share information. Transactional data from numerous sources may be readily integrated and shared via blockchain cloud services. The data is divided into shareable blocks linked together using cryptographic hashes to provide unique identification.


    Blockchain technology assures data integrity, establishes a single authentication source, reduces data duplication, and improves security. Fraud and data tampering is avoided in a blockchain system because data cannot be updated without the approval of a quorum of the parties involved. If someone tries to change the data, all participants and the individual responsible will be alerted.

    To have a clearer understanding of What is Blockchain, it can be considered a cloud-service-based platform that maintains a series of recorded transactions, with each block chained to the preceding block in a series and immutably recorded over a peer-to-peer network. Furthermore, cryptographic trust and assurance technology assigns each transaction a unique identification or digital fingerprint.

    Several notable blockchain systems have arisen in recent years, including Ethereum, Hyperledger, R3, IBM Blockchain, Cardano, and Avalanche. Each platform has its own set of features, benefits, and applications.

    Examples of Blockchain Platforms

    Below are few blockchain platforms that can be used for applications

    → Ethereum

    Ethereum is a decentralized blockchain platform that is open source and allows developers to create and easily deploy decentralized apps (dApps).

    It is well-known for its smart contract feature, which allows for making complicated, self-executing algorithms that autonomously enforce an agreement's conditions. As a result, Ethereum is one of the most popular blockchain platforms, especially when it comes to developing decentralized finance (DeFi) apps, which are intended to deliver financial services without any interference from middlemen.

    → R3

    R3 is a blockchain platform that also provides enterprise-grade custom blockchain solutions such as Corda, a distributed ledger technology (DLT) platform developed for usage in financial services.

    Corda is a private, permissioned blockchain network, which, like Ethereum, enables numerous parties to conduct direct transactions without the need for middlemen.

    → Cardano

    Cardano is a decentralized blockchain platform noted for emphasizing sustainability, interoperability, and scalability.

    It is intended to be a third-generation blockchain platform conceptualized to alleviate the shortcomings of first- and second-generation blockchain systems. Cardano employs a proof-of-stake consensus process, which is intended to be more energy-efficient than other blockchain systems.

    → Avalanche

    Avalanche is a decentralized blockchain platform with low latency and great throughput.

    It employs an Avalanche consensus method, intended to be quick and efficient while giving high-security assurances. Avalanche is intended for use in the development of decentralized apps with high transaction throughput, such as decentralized exchanges (DEXs) and gaming applications.

    What is NFT?

    Non-fungible tokens, often known as NFTs, are a type of digital asset that is stored on a blockchain. NFTs are a uniquely digital way to represent precious real-world commodities like art, music, in-game items, and films. They are purchased and traded online and have unique identifying codes

    NFTs in this digital era have skyrocketed significantly, given their ability to generate 'digital scarcity' as the tokens assigned for each asset are limited.

    This feature distinguishes them from most digital products, which nearly invariably have a limitless supply.

    An NFT further entitles the buyer to the original object and includes built-in authentication, which serves as evidence of ownership. Unlike cryptocurrencies, NFTs are not interchangeable; each has a unique identity that distinguishes it from the rest. Collectors cherish and take pride in their so-called "digital bragging rights" of possessing a unique object, which makes them precious. Even though the original item is freely available online, possessing the NFT provides the owner with the satisfaction of owning the original thing and proof of ownership.

    What are the Benefits of Blockchain

    → Enhanced Security through DLT

    Distributed ledger technology is the one feature that makes blockchain platforms and technologies unassailable.

    This advances and improves blockchain security and assures that it is the most challenging piece of database technology to be hacked.

    Whether it's your cryptocurrencies, non-fungible tokens, or smart contracts, blockchain assures that no one can alter it unless they have the necessary key, regardless of how it's distributed and maintained.

    Moreover, the blockchain prevents fraud or suspicious activity by producing a record that cannot be altered and is encrypted end-to-end.

    In the blockchain, privacy concerns may be solved by anonymizing personal data and using permissions to restrict access. As information is kept over a network of computers rather than on a single server, making data access is harder for hackers.

    → Transparent and Fixed Records

    Another key benefit of the blockchain platform and technology is its ability to create transparent and fixed record entries.

    Blockchain guarantees that any attempted adjustments or editing are prohibited and that the accuracy of the recorded data is preserved by spreading the concerned information across various network nodes.

    Let's take an example of a blockchain platform like Ethereum; if any particular node or access point in the blockchain ledger gets tampered with, it would still have to be cross-verified by other nodes available on the chain, as the previous node has been tarnished, it would automatically detect from its record the information as incorrect.

    Thus, resulting in a transparent and accurate sequence of events that cannot be changed by any single node in the network or even by multiple changes.

    Furthermore, such a piece of technology can also be utilized for storing information, comparing legal contracts, state identifications, or a company's goods inventory, expanding the technology's benefits.

    → Quicker Traceability

    Blockchain technology's traceability is another fundamental benefit. As it aids in producing an unalterable record of an asset's path from its inception to its current position.

    This is especially crucial in companies where clients are anxious about environmental or human rights concerns, counterfeiting, and fraud.

    Blockchain technology allows consumers to understand the complete journey of a product, including where it was obtained and how it was moved, by offering a clear and transparent audit trail. This can assist in building trust in the product through traceability, especially for companies involved in manufacturing and distribution.

    Moreover, traceability data can further disclose any flaws or inefficiencies in the supply chain, helping businesses to enhance and optimize their operations.

    → Structuring for Better Efficiency and Speed

    Another significant benefit of blockchain technology is its organized and efficient data storage and administration approach. Blockchain produces a clear and structured record of transactions that is simple to track and verify by grouping data into blocks and connecting them to form a chain.

    This method removes the need for manual reconciliation of numerous ledgers and decreases the possibility of human mistakes, making it less time-consuming. As a result, transactions are performed more quickly and effectively, eliminating the need for third-party mediation.

    Furthermore, by keeping paperwork and transaction data on the blockchain, there is no need for paper exchange, further simplifying and lowering expenses.

    What is the future of Blockchain Technology?

    According to Markets & Markets, the worldwide blockchain industry is predicted to grow at a CAGR of 66.2% over the forecast period, with revenue expected to climb from $7.4 billion in 2022 to more than $94.0 billion by the end of 2027.

    It's further assumed that blockchain platforms and technologies' huge demand, owing to its benefits of data security and transparency, has brought a significant amount of trust, especially from millennials and Gen Z, who keep data security of utmost importance.

    However, the proliferation of blockchain in retail, banking, healthcare, and supply chains has further ramped up its demand and made its future bright like a shining star.
