Understanding the Evolution: From Web1 to Web2 

To understand Web3, it’s essential to first grasp the concepts of Web1 and Web2. Web1, the initial version of the internet, emerged in the 1990s and early 2000s. It was primarily built on open protocols, which allowed anyone to exchange information freely. During this period, the internet was mainly used for reading web pages and chatting with friends or strangers. 

As Web1 evolved, it became a platform for e-commerce and academic and scientific research. Web2 began in the mid-2000s with the rise of new internet companies like Facebook, Twitter (now X), and Wikipedia. These platforms enabled users to create their own content.  

Importance of Web3 

Understanding the significance of Web3 is crucial as it revolutionises the internet, empowering users with enhanced control, security, and transparency. Let's delve into why Web3 matters and how it is transforming our digital landscape. 

1) Ownership 

Web3 indeed revolutionises digital asset ownership through NFTs. These tokens provide verifiable ownership of digital assets on the blockchain, ensuring that items cannot be taken away by game creators or other centralised entities. 

2) No Censorship 

Web3 technologies offer a decentralised approach, reducing the risk of censorship and sudden policy changes that can impact creators. Platforms built on Web3 principles allow creators to maintain control over their content and revenue streams. 

3) DAOs Autonomy 

Decentralised Autonomous Organisations (DAOs) enable collective ownership and decision-making. Token holders can vote on proposals, and smart contracts execute decisions automatically, promoting transparency and community governance. 

4) Identity 

Web3 simplifies identity management with Ethereum addresses and the Ethereum Name Service (ENS). This allows for a single, secure, and censorship-resistant login across multiple platforms, enhancing user privacy and control. 

5) Direct Payments 

Web3’s payment systems use cryptocurrencies like ETH for direct transactions, bypassing traditional banks and payment processors. This inclusivity allows anyone with internet access to participate in the digital economy.

Working of Web3 

Web3 operates on decentralised networks using Blockchain technology. Transactions are verified and recorded securely through consensus algorithms across a distributed network of computers. This decentralised approach ensures transparency and resilience against tampering, reducing reliance on centralised intermediaries. 

Smart Contracts in Web3 automate agreements, enhancing efficiency and trust in digital interactions without intermediaries. This new paradigm aims to empower individuals. It grants them greater control over their data and assets, fostering a more secure and equitable internet environment. This includes enhanced privacy protections and reduced censorship risks. 

Use Cases of Web3 

The following use cases illustrate Web3's capacity to empower individuals, enhance transparency, and foster innovation in a rapidly evolving digital landscape.
 

1) Decentralised Finance (DeFi): 

DeFi is a leading application of Web3, providing decentralised alternatives to traditional financial services like lending, borrowing, and trading. Platforms such as Compound, Aave, and Uniswap enable peer-to-peer transactions, avoiding the need for middlemen such as banks. 

2) Non-Fungible Tokens (NFTs): 

NFTs have become highly popular as unique digital assets that represent ownership of digital art, collectables, and virtual real estate. Web3 supports the creation, trading, and ownership of NFTs on Blockchain platforms like Ethereum, offering new monetisation opportunities for artists and creators. 

3) Decentralised Autonomous Organisation: 

Web3 enables the formation of DAOs, which are decentralised entities governed by Smart Contracts and managed by community members. DAOs facilitate collective decision-making, funding allocation, and project management without centralised control.  

4) Supply Chain Management: 

Web3 enhances supply chain transparency and traceability by recording every transaction and movement of goods on a Blockchain. This ensures authenticity, reduces fraud, and allows consumers to monitor the source and route of products. 

5) Identity Management: 

Web3 supports self-sovereign identity solutions, giving individuals full control over their personal data and digital identities. Blockchain-based identity management systems improve privacy, security, and interoperability across various services. 

6) Gaming: 

Web3 is revolutionising the gaming industry by enabling genuine ownership of in-game assets, ensuring provably fair gameplay, and fostering player-driven economies. Games such as Axie Infinity and Decentral and utilise Blockchain technology to create immersive experiences and generate new revenue streams for gamers. 

7) Voting and Governance: 

Web3 improves voting and governance processes by offering transparent and tamper-proof mechanisms for elections and decision-making. Decentralised Autonomous Organisations and Blockchain-based voting systems ensure accountability and prevent manipulation.

Technologies Behind Web3 

The following are the main technologies behind Web3: 

1) Blockchain Technology: Blockchain forms the backbone of many Web 3.0 applications, offering transparency and immutability. It is a decentralised and distributed ledger that records transactions or data across a network of nodes. Data is stored in chronologically consistent blocks that can only be deleted or modified with consensus from the peer-to-peer network. This ensures an unalterable ledger for tracking various transactions. 

2) Tokenisation: Tokenisation broadens Blockchain uses by reflecting practical or digital assets as digital tokens on the Blockchain. These tokens can represent ownership, access rights, or other forms of value, such as real estate, stocks, commodities, art, music, and in-game items. Tokens can be divisible and easily tradable, with types including security tokens and non-fungible tokens (NFTs). 

3) WebAssembly (Wasm): WebAssembly is a binary instruction format for a stack-based virtual machine that operates in a sandboxed environment within the browser. It enables high-performance code execution within web browsers, allowing decentralised applications to run efficiently across different platforms. This provides an enormous performance gain over typical web technologies such as JavaScript. 

 4) Semantic Web Technologies: These technologies help applications better understand and interpret data by using linked data principles to interlink multiple datasets or publish structured data on the web. Examples include: 

a) Resource Description Framework (RDF): RDF expresses statements as triples (subject-predicate-object) to create a graph-based data structure representing relationships between entities. SPARQL is a query language used to query RDF data. 

b) Web Ontology Language (OWL): OWL is used to define ontologies or formal representations of knowledge and relationships between concepts. It specifies classes, properties, and instances, facilitating reasoning and inferencing.
