The research question of how to make blockchain be able to deal with various data types has not been well studied. In this paper, we propose a single-chain based extension model of blockchain for fintech (SEBF). In the financial environment, we design a four-layer architecture for this model. By employing the external trusted or-acle group and a financial regulator agency, a variety types of data can be effectively stored in the blockchain, such that the data type extension based on a single-chain is realized. The experimental results indicate that the proposed model can improve the efficiency of simplified payment verifi-cation.<\/jats:p>","DOI":"10.24963\/ijcai.2020\/620","type":"proceedings-article","created":{"date-parts":[[2020,7,8]],"date-time":"2020-07-08T12:12:10Z","timestamp":1594210330000},"page":"4497-4505","source":"Crossref","is-referenced-by-count":4,"title":["SEBF: A Single-Chain based Extension Model of Blockchain for Fintech"],"prefix":"10.24963","author":[{"given":"Yimu","family":"Ji","sequence":"first","affiliation":[{"name":"Nanjing University of Posts and Telecommunications"},{"name":"Jiangsu High Technology Research Key Laboratory for Wireless Sensor Networks"},{"name":"Institue of High Performance Computing and Bigdata, Nanjing University of Posts and Telecommunications"},{"name":"Nanjing Center of HPC China"},{"name":"Jiangsu HPC and Intelligent Processing Engineer Research Center"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weiheng","family":"Gu","sequence":"additional","affiliation":[{"name":"Nanjing University of Posts and Telecommunications"},{"name":"Institue of High Performance Computing and Bigdata, Nanjing University of Posts and Telecommunications"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fei","family":"Chen","sequence":"additional","affiliation":[{"name":"Nanjing University of Posts and Telecommunications"},{"name":"Institue of High Performance Computing and Bigdata, Nanjing University of Posts and Telecommunications"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoying","family":"Xiao","sequence":"additional","affiliation":[{"name":"Nanjing University of Posts and Telecommunications"},{"name":"Institue of High Performance Computing and Bigdata, Nanjing University of Posts and Telecommunications"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Sun","sequence":"additional","affiliation":[{"name":"Nanjing University of Posts and Telecommunications"},{"name":"Institue of High Performance Computing and Bigdata, Nanjing University of Posts and Telecommunications"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shangdong","family":"Liu","sequence":"additional","affiliation":[{"name":"Nanjing University of Posts and Telecommunications"},{"name":"Jiangsu High Technology Research Key Laboratory for Wireless Sensor Networks"},{"name":"Institue of High Performance Computing and Bigdata, Nanjing University of Posts and Telecommunications"},{"name":"Nanjing Center of HPC China"},{"name":"Jiangsu HPC and Intelligent Processing Engineer Research Center"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"He","sequence":"additional","affiliation":[{"name":"Nanjing University of Finance and Economics"},{"name":"Swinburne University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunyao","family":"Li","sequence":"additional","affiliation":[{"name":"Nanjing University of Finance and Economics"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaixiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"WeBank Co., Ltd."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fen","family":"Mei","sequence":"additional","affiliation":[{"name":"WeBank Co., Ltd."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fei","family":"Wu","sequence":"additional","affiliation":[{"name":"Nanjing University of Posts and Telecommunications"},{"name":"Institue of High Performance Computing and Bigdata, Nanjing University of Posts and Telecommunications"},{"name":"Nanjing Center of HPC China"},{"name":"Jiangsu HPC and Intelligent Processing Engineer Research Center"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10584","event":{"number":"28","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"acronym":"IJCAI-PRICAI-2020","name":"Twenty-Ninth International Joint Conference on Artificial Intelligence and Seventeenth Pacific Rim International Conference on Artificial Intelligence {IJCAI-PRICAI-20}","start":{"date-parts":[[2020,7,11]]},"theme":"Artificial Intelligence","location":"Yokohama, Japan","end":{"date-parts":[[2020,7,17]]}},"container-title":["Proceedings of the Twenty-Ninth International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2020,7,9]],"date-time":"2020-07-09T02:16:18Z","timestamp":1594260978000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2020\/620"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2020,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2020\/620","relation":{},"subject":[],"published":{"date-parts":[[2020,7]]}}}
