originally has the characteristics of a decentralized architecture, today it is being operated as a centralized architecture. Because of this, criticisms are growing that people are being deprived of opportunities to transmit information freely without any constraints. The decentralized architecture represented by a blockchain is now considered to be an important technology for the Internet to restore the decline in degrees of freedom and capability in diversity which both were due to the centralized architecture. In the field of education, the main learning support systems such as learning management system (LMS) also have characteristics of centralized architecture. We have pioneered in developing a decentralized architecture based learning support system, CHiLO (Creative Higher Education with Learning Objects). In this paper, we will report the development of the proof of concept (POC) system which will further enhance the decentralized architecture of CHiLO with the adoption of the blockchain. The system solves problems regarding the distribution of ebooks without depending on the centralized management servers such as ebook stores and LMS, and the copyrights of CHiLO Books.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"72","bibliographic_titles":[{"bibliographic_title":"インターネットと運用技術シンポジウム論文集"}],"bibliographicPageStart":"65","bibliographicIssueDates":{"bibliographicIssueDate":"2017-11-30","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2017"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:52:01.112106+00:00","id":184698,"links":{}}
