The Internet was created as a decentralized and autonomous system of interconnected computer networks used for data exchange across mutually trusted participants. The element technologies on the Internet, such as inter-domain and intra-domain routing and DNS, operated in a distributed manner. With the development of the Web, the Web has become indispensable in daily life. The existing web applications allow us to form online communities, generate private information, access big data, shop online, pay bills, post photos or videos, and even order groceries. This is what has led to centralization of the Web. This centralization is now controlled by the giant social media platforms that provide it as a service, but the original Internet was not like this. These giant companies realized that the decentralized network's huge value involves gathering, organizing, and monetizing information through centralized web applications. The centralized Web applications have heralded some major issues, which will likely worsen shortly. This study focuses on these problems and investigates blockchain's potentials for decentralized web architecture capable of improving conventional web services' critical features, including autonomous, robust, and secure decentralized processing and traceable trustworthiness in tamper-proof transactions. Finally, we review the decentralized web architecture that circumvents the main Internet gatekeepers and controls our data back from the giant social media companies.

세계 디지털화의 흐름이 경제, 신원 인증, 물류 분야 등에서 블록체인 혹은 분산원장을 기반으로 한 탈중앙화 시스템 환경으로 변화하고 있다. 이에 맞추어 이내비게이션 서비스의 접근성에 있어서도 탈중앙화된 여러 해사 서비스 레지스트리(MSR)들로부터 공개 서비스를 검색할 수 있어야 한다는 요구사항이 도출되었다. 본 연구는 MSR 분산원장과 다수의 지역 MSR로 구성된 탈중앙화 MSR 환경을 기술하고, 이 환경에서 웹 브라우저 기반의 글로벌 이내비게이션 서비스를 검색할 수 있는 서비스 검색 시스템을 구현하였다. 동적으로 서비스 속성, 지역 정보, 자유 텍스트 검색 질의를 생성하여 MSR 분산원장에 등록된 검색 결과를 통해 유관 MSR과 서비스 접속 정보를 사용자에게 제공하는 탈중앙화 애플리케이션이다. 본 연구에선 구축된 탈중앙화 MSR 환경과 그 환경 내에서 서비스 검색을 수행하는 시스템을 실험하였고 이를 통해 가지는 장점 및 한계점에 대한 논의를 갖는다.

The reliability modeling of distributed systems requires a good understanding the reliability of the components. For thousands of web users, competitiveness in web services means a successful presence on the web. Mean time between failures of a web site on SOAP12/HTTP is considered, where SOAP12 is a protocol intended for exchanging structured information in a decentralized, distrbuted environment. Data were collected from statlab.cam.ac.uk/webstat/stat.html via the internet.

Most common web or application system architectures have central network. As a result, central network can be supervised and controlled in all situation. And It has the advantage of easy to manage and fast to work. However, central network have a disadvantage of weak to security and unclear. In particular, many institutions used by web system be has many problems by central network. In this paper, we proposed blokchain technology based on ethereum to resolve of problem and trading structure that arise in cental network. We propose a decentralized application based on points including cryptocurrency functions and smart contract to the advantages of blockchain with a decentralized structure. The results of the performance experiment are as follows; It has shown the advantages of reliable use and security in a variety of environments(Windows, Ubuntu, Mac).

Web 3.0 is a new web paradigm that aims to overcome the excessive commercialism and influence of big tech companies. Web 3.0 can be defined as a user-centered decentralized Internet environment, and Web 3.0 is a mixture of various terms and technologies such as blockchain, cryptocurrency, NFT, artificial intelligence, and metaverse. When new technology fields emerge, it is common to have positive and negative evaluations. As a result, rather than deciding which position is correct, it is necessary to investigate the causes and directions of change and prepare to seize the opportunity. In light of this, the present study examines the change in the web paradigm and the context of the emergence of Web 3.0, investigates the characteristics and major cases of Web 3.0, and discusses future issues and prospects.

In this paper, we are interested in how creator economy startups allowing creators to make money from doing that they love. So, we look at European creator economy startups among Web3.0 business model landscape surveyed in 2022, because the US is home of Web2.0 giant platforms like YouTube. Totally seventeen European startups are investigated, and the theoretical logic is the disruptive innovation. We firstly review the survey published in 2022 and utilize the theory of the disruptive innovation to design the research framework including questions with each type of the disruptive innovation. In this paper, we firstly show, Kalao and Gem as NFT ecosystem platforms aim at service convenience. Secondly, Talkbase, Passionfroot, Bildr, Customuse, and Earnr aim at providing creator tools for under-skilled customers. Lastly, when it comes direct monetization with a decentralized business model, CrowdPad, Admix, GOALS, Realm, Dropstar, Pianity, Sonomo, Stage11, Miiji, and ReadyPlayerMe are representative. Despite the relatively small data size, the results are meaningful as they contribute to a more profound comprehension of the Web3.0 business models and offer guidance for future research directions.

본 논문은 웹 환경에서 기존의 웹서비스 골격과 기능을 유지하면서, 에이전트 사이를 조정하여 웹 서비스를 지원하는 새로운 시스템을 설계하고 구현하였다. 본 논문에서는 제안한 LDL을 사용함으로 에이전트가 사용자의 요청을 동적으로 수행 할 수 있었고, 그룹화된 에이전트들이 공동의 목표를 상호 협력적으로 수행하기 위해 위임 과정을 수행함으로써 멀티 에이전트에 의한 웹서비스의 가능성을 보였다. 구현된 시스템의 검증을 위해서 수식계산 시나리오를 사용하였으며, 실험결과 제안한 새로운 시스템은 웹 서비스를 위해 필요한 모듈 검색의 시간 비용이 절감됨을 알 수 있었으며, 일반 사용자도 쉽게 접근이 가능하였다.

SOAP(Simple Object Access Protocol) that is a late protocol for exchange of information with Web Services that is useful for implementing common functions in especially a large size business area, is a protocol that is a lightweight, XML-based protocol over HTTP for exchange to information in decentralized, distributed environments. In this paper, we implement SOAP-based Web Services that can use with a slip database, for common slip processing functions in enterprise accounts in order to enhance the transparency of transactions by slip processing system. The result of this paper will contribute to increasing the productivity of enterprises through enhancing the standardization of slip data, reusability of functions, convenience of access, and efficiency of implementing applications.

Location-based services are a recent concept that integrates a mobile device's location with other information in order to provide added value to a user. Although Location-based Services provide users with comfortable information, it is a complex task to manage and share heterogeneous and numerous data in decentralized environments. In this paper, we propose the Semantic LBS Model as one of the solution to resolve the problem. The Semantic LBS Model is a LBS middleware model that includes an ontology-based data model for LBS POI information and its processing mechanism based on Semantic Web technologies. Our model enables POI information to be described and retrieved over various domain-specific ontologies based on our proposed POIDL ontology. This mechanism provide rich expressiveness, interoperability, flexibility in describing and using information about POls, and it can enhance POI retrieval services.

GILS is decentralized collection of locators and associated information services used by the public either directly or through intermediaries to find information. This standard specifies how electronic network searches can be experessed and how results are returned. GILS is an innovative network approach to assist user in locating information resoruces. This thesis proposes architecture of GILS. First, we study fundamental implementation technologies by the way of GILS and Z39.50 protocol. And then, after surveying GILs related technologies we introduce web-based GILS implementation. This study failed to implement GILS in commercial sector, but have an impliction to raise further research issue.
