The internet is an entity that is constantly maturing. The codes that run in the backend are constantly changing and being updated, just like any popular website and app that keeps changing over time. Web3 was created by a computer scientist Gavin Wood, and it has been seen by some tech futurists as a glimpse into the future.
Built on top of blockchains, Web3 envisions a new, decentralized internet where users cooperatively administer distributed ledgers. Due to this communal nature of blockchains, Web3 is the beginning of a new era, one where a community-run network controls use and access rather than corporate giants of Web2.
What is Web3?
As a broad term, Web3 includes technologies such as blockchain that distribute ownership and control of data on the internet. Most internet applications are owned by a centralized party that decides how the data is stored and used by the end-users. Web3 technologies, also called Web 3.0 or decentralized web, stand in contrast to such centralized structures, where projects are community-driven.
End users in these projects retain control and pricing of the data, with direct contributions by end users to the technical development of a system, as well as a greater say in the system’s direction. These technologies then employ a protocol that autonomously regulates interaction among users so that no authority needs to oversee that interaction.
Core Principles Of Web 3.0
There are four main features of Web 3.0.
-
Decentralization
Decentralized web applications chiefly characterize Web 3.0. It is a mechanism by which data is distributed across different decentralized networks. The infrastructure belongs to different entities in such networks, whereby users pay the storage provider directly for accessing the said storage.
The decentralized app will also create replicas of information in multiple locations and maintain data consistency throughout all the locations. The individual user has control over where his/her data will reside, so there is no need for a centralized infrastructure. If users choose to do so, these decentralized internet users may sell their own data.
-
Trustlessness
With web applications and services being centralized, users often had to place some trust in a central authority that could then handle their data or sometimes even their transactions and interactions. That central authority itself had the power to hold and manipulate user data as per the system’s rules.
The data could be held with malicious intentions or could be grossly mismanaged, where the information would eventually be lost or misused. On the other hand, Web3 has been designed in such a way that users do not need to rely on third parties and instead trust is embedded in the transparent, verifiable code of the protocol itself.
-
Semantic Web
The Semantic Web will empower applications to accomplish more complex tasks by understanding the content and context of web data. It uses metadata and artificial intelligence to derive meanings (semantics) for the user-created data.
To this end, Web 3.0 strives to move towards embracing semantic web technologies that currently exist in some corners of web technologies. For instance, a search engine supports getting better and more contextually relevant search results, and intelligent agents perform tasks more efficiently on behalf of the user.
-
Interoperability
Web3 is simply reimagining the manner in which different kinds of technology interlock with each other. It enables data to flow between platforms directly, without the need for a centralized authority. And, in its emphasis on the principle of interoperability, that’s the thing: your profiles, preferences, and settings travel with you.
As systems get better at talking to one another, the ability for anyone, whether an average person or a tech professional, to choose freely between services becomes easier, without having to build everything from scratch.
At the same time, protocols that connect with a larger set of IoT (Internet of Things) devices might take the Web past the screen and into the real world in which we live and communicate with equipment around us. For instance, value exchanges across national and international borders are made possible by cryptocurrency technologies that facilitate borderless transactions.
Main Technologies In Web 3.0
Blockchain
In essence, a blockchain is a distributed, decentralized ledger that records data or transactions over a network of nodes. Once something is recorded, it is nearly impossible to change without the approval of the entire peer-to-peer network. It does this by storing information in a time-stamped chain of blocks.
This consensus mechanism stops any client from inserting arbitrary transactions and guarantees the consistent view of these transactions among all clients. Therefore, it could very well be used as an immutable ledger to track all sorts of transactions.
Tokenization
The area where blockchain technology expands its applications is through tokenization. Tokenization is a conversion process that turns all assets, real or digital, into token assets by means of applying blockchain technology.
The tokens are cryptographic representations of ownership, access rights, or other forms of value. For instance, one could represent physical and digital assets such as real estate, shares, commodities, art, and even music NFTs that empower artists to connect with fans using blockchain.
In public trading markets, a token can be treated as a fraction or whole unit of the underlying asset, such that it is divisible and easily traded. There are different sorts of tokens existing in the metaverse, like security tokens subject to securities laws or even NFTs representing unique indivisible assets that cannot be fractally owned.
Web Assembly
WebAssembly (Wasm) is the binary instruction format for a stack-based virtual machine. It runs in the browser, prob in a sandboxed environment, which means it has no access to your file system. Essentially, this is high-performance code executing within web browsers and offers the groundwork on which decentralized applications will be able to run on multiple platforms efficiently.
Developers can use it to execute code at speeds that are nearly on a par with those of native languages, thereby providing a vast improvement to their code in comparison to standard web technologies such as JavaScript.
Semantic Web Technologies
Semantic web technologies are a way for applications to interpret and reason about customer data. They link and interconnect several datasets or publish structured data on the web that is free to access.
- Resource Description Framework – Subject-predicate-object triples are a way to express facts according to the Resource Description Framework (RDF). These triples form a graph-like structure that maps out the relationships between different entities. To make sense of that data, you can use SPARQL – a specialized query language built for navigating RDF datasets.
- Web Ontology Language – An ontology definition language or a language for the formal representation of knowledge and conceptual links is called Web Ontology Language. In addition to reasoning and inference, it may be told to define classes, properties, and instances.
Challenges That Web 3.0 Implementations Face
Like any emerging technology, Web3 implementation faces several problems that must be fixed so that the technology can be widely adopted and become a success. Some of the principal challenges are given below.
Technical issues
Scalability is still a big issue as blockchain networks might become too expensive and computationally demanding as the volume of data grows. Attempts have been made to come up with a technology that is sustainable and environmentally compatible. Additionally, Interoperability between different blockchain networks and protocols is also a challenge.
User experience and adoption
Complex interfaces and difficulty of use are some of the main reasons Web3 has not gone mainstream yet. To update the user experience, interface designs must be intuitive enough to hide the inner complexities of blockchain technology.
Governance
Governance is difficult to generalize in decentralized systems since it requires workable structures that provide community involvement and do not centralize power. Designing effective tokenomics and token standards that truly represent the application and its own goals is a dilemma.
Road Ahead
The future of Web3 is surely going to be just as wondrous as it is uncertain. One big focus is going to be on mass adoption, and once developers find new avenues for user-friendly platforms and governments provide a regulatory framework, Web3 could achieve mainstream adoption once scalability, UX, and regulation are addressed. The future might even witness IoT devices working autonomously on blockchain networks or AI systems directly interacting over decentralised protocols.
Throughout the entire ride, there will be bumps here and there, but it is important that we find the right balance. This balance has to be established between decentralization and regulations. Governments will have to walk a tightrope – supporting innovation without losing sight of consumer protection.
