A Beginners' Guide to Blockchain Technology: How it works and evolves?
Newcomers exploring blockchain technology often discover it as an exciting and rewarding field filled with intriguing challenges. This section is the perfect starting point for you to embark on your journey of learning about this technology. Blockchain doesn't have to be scary, and we're here to simplify blockchain fundamentals and its evolution.
1 Basics of Blockchain Technology
What is Blockchain?
Let's decode the word “blockchain". Blockchain consists of “block" and “chain". Block is where your data is stored in a secure, transparent, and immutable manner. Blocks are connected to each other, in which data is linked to the previous ones, forming a chain.
With blockchain, there are only decentralized databases, which means distributing control and decision-making across many computers in a network, rather than having one central authority. The data is chronologically consistent because you cannot delete or modify the chain without consensus from the network.
One might wonder about the types of data recorded in these blocks. Various kinds of data can be documented; however, to simplify, given the widespread adoption of blockchain technology in cryptocurrency and digital finance, the most commonly recognized data type is 'transactions'.
At this point, let's say blockchain technology is a decentralized and distributed ledger that records transactions across multiple computers in a secure, transparent, and immutable manner.
An Overview of how blockchain technology works
To delve into the mechanics of blockchain technology, it is essential to address the question: "What entities are responsible for the functioning of blockchain?" The answer lies in two primary components: miners and nodes. These elements play crucial roles in maintaining and facilitating the operations of the blockchain network.
Miners: Real world miners mine rock to find precious ores and receive iron or gold as their reward. The same process happens in the cryptocurrency world.
Nodes: Unlike miners, which are block creators, full nodes act as a sort of librarian for the “blockchain library” and they do not receive direct rewards for their work.
Nodes are individual computers that participate in the network by validating and broadcasting transactions to the entire network, storing a copy of the blockchain to ensure the network’s decentralization and security.
In short, while all miners are nodes, not all nodes are miners. Nodes serve to maintain the blockchain network, while miners are responsible for validating and adding transactions to the blockchain.
2 The Evolution of Blockchain Technology
Understanding the significant evolution of blockchain technology from its inception is essential for gaining comprehensive insights. This understanding can be facilitated through a concise three-minute read provided below.
Blockchain 1.0: The Emergence of Cryptocurrencies
Blockchain 1.0, also known as the first generation of blockchain technology, has been rapidly developing since Satoshi Nakamoto introduced Bitcoin in 2008 as a blockchain-based digital currency.
Following Bitcoin, developers began to explore the possibilities of a technology called distributed ledger technology (DLT) in the finance world. Bitcoin and this new technology inspired the gradual creation of many other Blockchain 1.0 projects, marking the emerging era of cryptocurrencies.
For the first time in the world’s financial history, monetary transactions became completely decentralized. It was a significant step forward in the way we handle money.
Blockchain 2.0: Smart Contracts
Blockchain 2.0 represents the era of smart contracts that helped Blockchain to outgrow its original functionality of powering cryptocurrencies.
Smart contracts, enabled by blockchain technology, are self-executing agreements written directly into code, revolutionizing the way agreements are made and transactions are conducted.
This advancement enables a wide range of applications, including decentralized finance (DeFi), supply chain management, voting systems, digital identity, etc. while eliminating the need for intermediaries, reducing transaction costs, and increasing the efficiency and security of transactions.
In 2013, Ethereum was introduced as a 2nd-generation public blockchain. Like Bitcoin, Ethereum adapts the PoW consensus method, requiring heavy mining hardware and significant resources, gradually becoming the go-to Blockchain for enterprises across industries, especially supply chain, logistics, and cross border payments.
Blockchain 3.0: Decentralized Applications (Dapps)
Blockchain 3.0 has been all about the rise of Dapps! With a user-friendly frontend interface, dApps support various powerful blockchain use-cases like DeFi platforms, crypto loan platforms, NFT marketplaces, P2P lending, and others.
Ethereum kickstarted the dApp development and DeFi, and this concept found new dimensions with the introduction of 3rd generation dApp-focused blockchains like Cardano, Solana, IOTA, Nano, XDC, and many more.
These new entrants are improving blockchain adoption at the mass level by addressing the shortcomings in the second-generation blockchains. Powered by new consensus mechanisms, 3rd generation blockchain protocols are focusing on areas like speed, security, scalability, interoperability, and environmental friendliness.
Blockchain 4.0: The future blockchain technology
Blockchain 4.0 is anticipated to represent a significant leap forward in the integration of blockchain technology into real-life business scenarios, especially expected to bring about significant advancements in web3, metaverse, and their influence on Industry 4.0.
Moving away from the centralized models of Web 2.0, Web3 aims to give users more control over their data and digital interactions. With Blockchain 4.0, we can expect further Web3 developments, making them more suitable for widespread adoption and integration into various industries.
Metaverse, on the other hand, represents a digital universe where users can interact with each other and digital objects in real-time. Blockchain technology plays a crucial role in metaverse development by providing secure and decentralized infrastructure for virtual asset ownership, digital identity, and value exchange.
The influence of web3 and metaverse on Industry 4.0 is significant and potential to revolutionize various aspects including supply chain management, digital asset tracking, remote collaboration, and immersive training simulations.
By leveraging blockchain technology and its capabilities, industries can enhance efficiency, transparency, and trust in their operations, leading to a more interconnected and digitized industrial landscape.
