In today\u2019s society, people still have many taboos when writing a will. Writing a will not only involves various laws and regulations but also costs a lot of money and time, which can be daunting. However, with the development of the Internet, blockchain technology has gradually been applied to many applications. Blockchain technology uses consensus algorithms to ensure consistency and records transaction information in blocks to ensure the effectiveness of transactions. In this paper, we use the cryptography mechanism to propose an online will system based on blockchain and smart contract technology. The architecture considers effectiveness and cost reduction. By combining this with blockchain technology, will assets are saved in blocks, which provides comprehensive will security and non-tamperable security protection. In addition, combined with a smart contract, it realizes the method of automatic property distribution. At the same time, this mechanism also proposes an arbitration solution when there are disputes over wills, and ensures the integrity of data, public verifiability, unforgeability, nonrepudiation, irreversibility of information, and the ability to resist counterfeiting attacks.<\/jats:p>","DOI":"10.3390\/sym13030466","type":"journal-article","created":{"date-parts":[[2021,3,15]],"date-time":"2021-03-15T02:51:48Z","timestamp":1615776708000},"page":"466","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["A Traceable Online Will System Based on Blockchain and Smart Contract Technology"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4958-2043","authenticated-orcid":false,"given":"Chin-Ling","family":"Chen","sequence":"first","affiliation":[{"name":"School of Computer and Information Engineering, Xiamen University of Technology, Xiamen 361005, China"},{"name":"School of Information Engineering, Changchun Sci-Tech University, Changchun 130600, China"},{"name":"Department of Computer Science and Information Engineering, Chaoyang University of Technology, Taichung 413, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ching-Ying","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Information and Communication Engineering, Chaoyang University of Technology, Taichung 413, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mao-Lun","family":"Chiang","sequence":"additional","affiliation":[{"name":"Department of Information and Communication Engineering, Chaoyang University of Technology, Taichung 413, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong-Yuan","family":"Deng","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, Chaoyang University of Technology, Taichung 413, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peizhi","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Computer and Information Engineering, Xiamen University of Technology, Xiamen 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5632-9321","authenticated-orcid":false,"given":"Yi-Jui","family":"Chiu","sequence":"additional","affiliation":[{"name":"School of Mechanical and Automotive Engineering, Xiamen University of Technology, Xiamen 361024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,12]]},"reference":[{"key":"ref_1","unstructured":"Peter, A.
