Web3 101 편집하기

== 들어가며 ==
우리가 사용하는 월드 와이드 웹(World Wide Web, WWW)은 세 단계로 발전하고 있다.

* '''(Web 1.0)''' 단순히 정보를 제공받아 이용하거나 게시판 등으로 의사소통을 함
* '''(Web 2.0)''' 서비스 개인화는 물론 실시간으로 의사소통을 함 - ''SNS, e-커머스 플랫폼''
* '''(Web 3.0)''' 분산 웹 또는 Web3 이라고 불리며 신뢰할 수 있는 중개인(Trusted Third Party)이 없는 진정한 P2P 거래 구현 - ''a World Wide Web based on public blockchains providing decentralization and token-based economies''
** 2006년에 팀 버너스리(Tim Berners-Lee)가 Semantic web 을 Web 3.0 의 요소로 설명했는데 여기서의 Web 3.0 과 Web3 은 다르다. ([https://www.nytimes.com/2006/05/23/technology/23iht-web.html Link])

== 소개 ==
'''Web3''' 라는 용어는 2014년에 Polkadot 창업자이자 Ethereum 공동 창업자인 Gavin Wood 가 2014년에 "블록체인을 기반으로 한 분산화된 온라인 생태계(decentralized online ecosystem based on blockchain"를 소개하며 처음으로 언급되었다. 인터뷰에서 Gavin Wood는 Web3 에 대한 가장 간략한 정의로 '''“Less trust, more truth.”''' 라고 답을 했다.

현재 Web3는 존재하지만, 아직까지는 대부분 암호화폐 및 NFT에 치중되어 있으며  일반적인 인터넷 사용자가 사용하기에는 여러 난관이 있다.<blockquote>Right now Web3 does exist, but it exists largely in the crypto universe that involves digital currencies and the exchange of NFTs, and isn’t widely accessible to the average internet user. (Investors are betting $27 billion that Web3 is the future of the internet, NICOLE GOODKIND, December 7, 2021 4:10 AM GMT+9, FORTUNE)</blockquote>

== 발전방향 ==
Web 2.0 이 없어지는 것이 아니라 기존 서비스에서 Web3 기술을 추가할 가능성이 높다고 함.<blockquote>"I'm not in a position to say who will win," Dryhurst said. "But Web2 companies will be folding Web3 ideas into their services to stay relevant." (People are talking about Web3. Is it the Internet of the future or just a buzzword?, BOBBY ALLYN, November 21, 2021 6:00 AM ET, NPR)</blockquote>

== Web3와 함께 언급되는 용어 ==
Web3 관련 기사를 살펴보면 아래와 같은 용어가 함께 따라다니는 것을 알 수 있다.

* 모든 것의 민주화 - ''Democratize eveything''
* '''분산화(Decentralization)'''
* 소유권(ownership)의 이동 : 기업 → 사용자
* Blockchain 기술 - ''the backbone of the Web3''
* 대체 불가능 토큰(Non-Fungible Token, NFT)
* 자율 분산형 조직(Decentralized Autonomous Organizations, DAO)
* 탈중화 금융(Decentralized Finance, De-Fi)
* 자기주권신원(Self-Sovereign Identity, SSI)

== Web3 비판자 ==

* James Grimmelmann, 코넬 대학교 교수 who studies law and technology : "Web3 is vaporware<ref>software or hardware that has been advertised but is not yet available to buy, either because it is only a concept or because it is still being written or designed.</ref>...(생략)... Blockchains are interesting and solve some difficult problems in new ways. They're probably going to end up in the toolkit that the next internet is built out of, but that doesn't mean the internet is going to be built around them."
* 트위터 공동 창업자 & 전 CEO Jack Dorsey : "a venture capitalists' plaything."
* Space X 와 Tesla CEO Elon Musk : "Web3 seems more marketing buzzword than reality right now."
* 영국의 개발자 & 블로거 Stephen Diehl : "a vapid marketing campaign that attempts to reframe the public's negative associations of crypto assets into a false narrative about disruption of legacy tech company hegemony."
