"Web3"는 블록체인, 특히 이더리움과 관련된 분산 웹 기술을 지칭하는 용어입니다. Web3는 일반적으로 인터넷의 세 번째 버전을 나타내며, 사용자와 개발자 모두에게 중앙 집중식 플랫폼의 제한을 극복할 수 있는 새로운 방법을 제공합니다.
Web3의 주요 특징:
- 분산 웹: 웹3는 사용자의 데이터를 중앙 서버가 아닌, 블록체인 네트워크에 저장합니다. 이로 인해 데이터의 소유권과 보안이 강화되며, 중앙 집중식 기관이나 정부의 통제를 받지 않습니다.
- 스마트 컨트랙트: 스마트 컨트랙트는 자동 실행 코드로, 블록체인 상에서 동작합니다. 스마트 컨트랙트를 사용하면 사용자와 개발자는 투명하고 신뢰할 수 있는 거래를 할 수 있습니다.
- 디지털 자산: 웹3에서는 크립토커런시, NFT(Non-Fungible Token) 등 다양한 형태의 디지털 자산을 사용할 수 있습니다.
- 자율조직: DAO(Decentralized Autonomous Organization) 같은 개념이 도입되어 사용자들이 직접 플랫폼의 거버넌스에 참여하고 결정을 내릴 수 있습니다.
Web3의 발전 단계:
- Web1 (정적 웹): 웹의 초기 단계에서는 주로 텍스트와 이미지가 포함된 정적인 페이지만 제공되었습니다.
- Web2 (소셜 웹): 사용자가 콘텐츠를 생성하고 공유할 수 있는 플랫폼(예: 페이스북, 트위터 등)이 등장했습니다.
- Web3 (분산 웹): 블록체인 기술을 기반으로 사용자의 데이터 소유권과 투명성을 중시하는 인터넷의 새로운 형태입니다.
Web3가 주목받는 이유 중 하나는 중앙 기관의 통제 없이 개인의 데이터 소유권과 보안을 강화할 수 있다는 점입니다. 그러나 이 기술도 완벽하지 않으며, 아직 많은 도전 과제와 문제점이 남아 있습니다. 신기술에 대한 대중의 이해와 수용, 기술적인 한계, 법률 및 규제의 불확실성 등이 그 예입니다.
"Web3" or "Web 3.0" refers to a new paradigm for applications on the internet. It represents the third era of the web.
Web Evolution Overview:
- Web1 (The Static Web): The early web where content was read-only and static.
- Web2 (The Social Web): This era brought interactivity, social media, and user-generated content.
- Web3 (The Decentralized Web): The emerging era. It introduces decentralized protocols and technologies, enabling users to have control over their own data, identities, and transactions.
Key Features of Web3:
- Decentralization: Web3 reduces reliance on central authorities or intermediaries, like tech giants or financial institutions. Decentralized networks, like blockchains, are a crucial part of this.
- Cryptography: Cryptographic techniques secure transactions and data, ensuring privacy and enabling things like cryptocurrencies.
- Smart Contracts: These are self-executing contracts with the terms written into code, facilitating, verifying, or enforcing credible transactions without third parties.
- Token Economy: Digital assets or tokens can represent ownership or value in various applications, incentivizing users and developers in the ecosystem.
Web3 Market in IT Industry:
- Blockchain & Cryptocurrency Firms: Companies providing blockchain technology, cryptocurrency trading platforms, wallet services, etc.
- Decentralized Finance (DeFi): Services offering decentralized lending, borrowing, or trading financial instruments.
- Decentralized Autonomous Organizations (DAOs): Organizations run and managed by smart contracts and consensus among its members, rather than by a centralized authority.
- NFT Marketplaces: Platforms for creating, selling, and buying Non-Fungible Tokens, which represent ownership of unique items or content.
- DApps (Decentralized Applications): Applications that run on decentralized networks, often built using smart contracts.
- Infrastructure and Development Platforms: Companies providing tools, services, and infrastructure for developers to build and deploy Web3 applications.
- Identity & Security Solutions: Services offering decentralized identity and security solutions for users and applications in the Web3 space.
Market Impact:
- Investment Opportunities: The Web3 space has attracted significant investment from venture capitalists, individual investors, and corporations.
- Innovation & Startups: There’s a surge in startups and projects focused on decentralized technologies, services, and platforms.
- Job Creation: New career opportunities and roles are emerging, including blockchain developers, smart contract engineers, and decentralized finance analysts.
- Challenges & Risks: The space also faces challenges, like regulatory uncertainty, security concerns, and technology maturity and adoption issues.
Conclusion:
The Web3 market is dynamic and rapidly evolving, with many players entering the space and developing innovative solutions and services. As technologies mature and adoption grows, Web3 could substantially influence the IT industry and the broader economy, bringing about significant changes and opportunities.
Web 3.0
Though there are a number of differences between web 2.0 and web 3.0, at the heart of everything is decentralisation. Any issues surrounding security and monetisation would no longer be a problem due to the fact that web 3.0 is verifiable, self-governing and permissionless. Developers in web3 would not usually build apps that run on a single server or store information in a single database, instead, everything would become decentralised.
Essentially, apps on web 3.0 would normally run using blockchain technology. This is the same kind of tech that helps to create cryptocurrency and as such, is completely decentralised. Cryptocurrency will also play a large role in these protocols as it will provide financial incentive to those who create decentralised apps and those who govern and improve them.
Thanks to the decentralised nature of web3, it would mean that organisations would no longer be able to retain data about what you do on the internet. Instead, once you log off, you would take your data with you. It means that web3 is not prone to the same security risks that come with the internet we are currently using.
