Web 3.0 is the next evolution of the internet, promising a more decentralised, user-centric, and intelligent web experience, largely driven by advancements in artificial intelligence (AI), machine learning (ML), and blockchain technology.
Decentralisation
One of the core principles of Web 3.0 is decentralisation. Unlike Web 2.0, where large companies control vast amounts of user data, Web 3.0 aims to give control back to the users. Blockchain technology better enables peer-to-peer networks and decentralised data storage, allowing for the secure and transparent transfer of data and assets without the need for intermediaries like Google, Facebook or large banks. This can manifest through decentralised applications (dApps), which run on blockchain networks like Ethereum, rather than centralised servers.
Metaverse
The metaverse is a virtual, interconnected space where people can interact, socialise, and trade. Web 3.0 enables true digital ownership through NFTs. Users can own virtual land, avatars, art and assets that are verifiably theirs, independent of any platform provider. This allows for greater interoperability across different virtual worlds, as these assets can be transferred or used in multiple metaverse environments. DeFi further supports a new economic model for the metaverse, where users can trade, invest, and monetise their assets without relying on centralised financial institutions. Web 3.0 is the backbone that makes the metaverse scalable, secure, and user-centric, driving innovation and empowering individuals within virtual spaces.
DAOs
One significant development that has sought to unlock the benefits of blockchain is the use of Decentralised Autonomous Organisations. These enable communities of people that hold the relevant governance tokens to vote on the development tasks, budget allocation and other key issues in relation to the community dApp. In some cases this can make it challenging to apply traditional regulatory frameworks (securities law, collective investment scheme rules, online gambling requirements) to these platforms and products since there may be no central controller or manager of the products.
Semantic Web / AI
Another key feature of Web 3.0 is the use of the semantic web, where websites and applications can understand and interpret data in a way that resembles human understanding. By integrating AI and machine learning, Web 3.0 can create more personalised and adaptive experiences..
Personalisation and Control
Web 3.0 enables users to have greater control over their personal data. Blockchain allows for the creation of self-sovereign identities where users control who accesses their data, as opposed to the current model where companies own user data. Cryptocurrencies and DeFi are a good example of this shift, allowing users to conduct financial transactions without intermediaries and securely store their wealth on blockchain wallets.
Interoperability
Web 3.0 emphasises cross-platform integration, where services and applications can work together seamlessly across different platforms. For instance, a user could log into various services using a single blockchain-based identity or move digital assets (like NFTs or tokens) between different dApps and platforms.
Web 3.0 Examples
- DeFi Platforms: like Aave or Uniswap allow users to lend, borrow, and trade digital assets without relying on traditional banks or brokers.
- Publishing Platforms: Projects like Steemit or Mirror.xyz allow users to publish content while maintaining ownership over their data, and they can be rewarded in cryptocurrencies.
- Gaming and Asset Ownership: Blockchain-based environments like Decentraland and Axie Infinity let players truly own in-game assets (such as land or characters), which can be bought, sold, or traded on decentralised markets.
- Gambling: Decentralised sports betting exchanges like dexsport.io and casinos like BC.Game which state that they use provably fair games and provide a validation tool.
