Web3 - An Introduction and Its Potential

Wednesday, June 26, 2024

Called the next generation of the web, Web3 heralds a new paradigm for interacting with digital services and managing our online identities. In this way, it differs from primarily centralized Web2.
Web3 is actually based on decentralized technologies like blockchain, with the idea that control and ownership come back to the users.

What is Web3?

To understand Web3, it is necessary to consider its history as a static web (Web1) and an interactive, social web (Web2). At a basic level, Web3 involves building a decentralized and user-centric Internet model. This means that instead of relying on centralized servers and services controlled by a few big corporations, Web3 applications run on decentralized networks where data is owned and controlled by the users.

Key Technologies
Web3 is based on blockchain technology, which offers an open, transparent, and immutable ledger for recording transactions. Also important are self-executing contracts, with the terms of the agreement written directly into code: smart contracts. These technologies enable the creation of decentralized applications (dApps) that operate without intermediaries.

Importance of Decentralization
Decentralization is a core tenet of Web3. It brings better security, privacy, and resistance to censorship by distributing data and computing power across a network rather than at central points of control. It's almost as if we were moving from a monarchy, with just one entity in control, to a democracy where power gets distributed among many participants.

Role of Blockchain Technology
Blockchain, as a foundation for Web3, provides security, transparency, and an unhackable way to record transactions. Each block contains a list of transactions and is consequently tied to the former block in such a way that, in turn, they form a chain. This way, data is secured on the blockchain, as it can never be tampered with without changes in all the following blocks of data, making it very trustworthy.

Smart Contracts

What is a Smart Contract?

Smart contracts are self-executing agreements to enforce predetermined rules on a blockchain. They operate on a blockchain, thus assuring parties that the contract conditions will be met without requiring intermediaries. For instance, an application based on decentralized insurance would imply automatic execution by a smart contract and payment upon realization of one or several of the flight-delay conditions—verified by trustworthy off-chain sources.

Potential of Web3

Financial Inclusion
Decentralized Finance (DeFi)
Web3 has given birth to DeFi—a move aimed at creating an open financial system that everybody can access with just an internet connection. DApps (Decentralized Applications) on DeFi platforms allow users to lend and borrow, trade, and generate interest from their held assets without needing a traditional bank. For example, Aave and Compound allow users to lend their crypto assets to others and earn interest. Meanwhile, decentralized exchanges like Uniswap facilitate peer-to-peer trading.

Ownership and Digital Assets
Non-Fungible Tokens, or NFTs, have gained prominence in Web3 as forms of ownership over unique digital items like art, music, and virtual real estate. An NFT is an exceptional asset, unlike regular fungible cryptocurrencies, by which blockchain-enforced proof of ownership and provenance is provided. Some popular platforms—like OpenSea and Rarible—have made it easy for artists and creators to mint and sell their digital works as NFTs.

User Control Over Data
One of the most exciting features of Web3 is the emphasis on user control over their data. Data gathered in Web2 gets collected, stored, and monetized by giant corporations. Web3 allows users to own and control their data, deciding who can access it under what conditions. Projects like Filecoin and IPFS ensure decentralized storage is secure, making the data accessible only by people with permission.

Interoperability and Innovation
This is necessary for Web3 applications to run on all blockchain networks flawlessly. Cross-chain solutions massively increase the functionality of moving assets and data across different blockchains, thus ensuring greater liquidity and functionality. For example, Polkadot and Cosmos were created to realize seamless inter-blockchain communication and interoperability, making the whole ecosystem more interconnected and flexible.

The future of Web3 and Blockchain

What are the Challenges for Web3?

Scalability Issues
As promising as Web3 may seem, there are many challenges that come along with scaling. Current blockchain networks, like Ethereum, have clogged up several times in the past, which—thanks to demand—have super-slow transaction times and high fees. This ironically renders most Web3 applications nearly unusable as a public service at scale, in other words, during peak usage. To solve that, we're looking at Layer 2 scaling solutions such as sharding and new consensus mechanisms.

Crypto and Web3 Regulations
Web3 regulatory environment is yet under construction. This development faces existing governments and their bodies in establishing how they will regulate decentralized technologies. Issues around AML, KYC requirements, and tax compliance make these problems quite burdensome for Web3 projects. Thus, further balancing innovation with the rigors of regulatory compliance shall be vital for the mainstream adoption of Web3.

User Adoption Barriers
There are difficulties both in a technical and educational sense in users adopting Web3 technologies. Most users believe that blockchain technology is complicated to understand. It will be nearly impossible to get full-scale users into Web3 without mainstream interfaces and deep educational support. Therefore, it is essential to emphasize drives related to accessibility and education.

Scams in Web3
Where Web3 promises more security and control to users, it opens a new window for scams and fraud. The pseudonymous and decentralized nature of blockchain transactions makes fund recovery extremely tricky. The most common forms of scam in the Web3 space are phishing attacks, rug pulls, and fraudulent coin offerings.

What is the Future of Web3?

Future Trends in Web3
Web3 will develop, and it will be characterized by several trends: the increase in decentralized autonomous organizations (DAOs), permitting communities to be run or managed from the bottom-up without central control; growth in decentralized identity solutions, resulting in much more power over online identity for users; the integration of AI and machine learning with Web3, basically making the automation and intelligence within decentralized applications possible.

Industries Transforming with Web3
Web3 is expected to revolutionize finance and other industries. Applications could be in health, where the blockchain enables the creation of safe, interoperable patient records that guarantee privacy and better care coordination. In supply chain management, it could increase transparency and traceability while reducing fraud and inefficiencies. Real estate, gaming, and entertainment will benefit immensely from Web3.

With challenges of scalability, regulation, and user adoption, the democratization of information and financial services is possible under Web3. To nurture this ecosystem for innovation, overcome the barriers, and raise enabling awareness, it will be critically important to help unlock the potential of Web3. It is a worthwhile step for anyone interested in the future of the Internet to engage with Web3 technologies and communities. Be it a developer or investor, this could help one, even as a curious user trying to analyze different kinds of applications and innovations in Web3, to understand better the broad, disruptive potential that is before us. Looking further into the future, Web3 will continue to develop and be adopted, actually restructuring our digital landscape, creating new opportunities, and changing how we will interact with the online world.

Our investment strategy involves providing deep liquidity crypto market making to the projects we invest in. This approach allows us to ensure continuous and substantial liquidity in exchanges. By doing so, we aim to increase market efficiency and reduce price volatility. We help to stabilize prices and reduce the bid-ask spread, which can lower transaction costs for traders. This usually attracts more traders to the markets, by making it easier and less risky to trade your token which can help to increase the overall liquidity and trading volumes both for the benefit of traders and issuers. However, we recognize that providing liquidity also comes with potential risks, which we carefully evaluate and manage as part of our investment decision-making process.
