Especially in developing countries, corruption is a widespread issue due to secrecy and lack of transparency. An important instrument for transparency and accountability assurance is the record which is managed and controlled by recordkeeping systems. Blockchain technology and more precisely blockchain-based smart contracts are emerging technological tools that can be used as recordkeeping systems and a tool to mitigate some of the fraud involving public procurement records. Immutability, transparency, distribution and automation are some of the features of smart contracts already implemented in several applications to avoid malicious human interference. In this paper, we discuss some of the frauds in public procurement, and we propose smart contracts to automatize different stages of the public procurement procedure attempting to fix their biggest current weaknesses. The processes we have focused on include the bidding process, supplier habilitation and delivery verification. In the three subprocesses, common irregularities include human fallibility, improper information disclosure and hidden agreements which concern not only governments but also civil society. To show the feasibility and usability of our proposal, we have implemented a prototype that demonstrates the process using sample data.<\/jats:p>","DOI":"10.3390\/computers10070085","type":"journal-article","created":{"date-parts":[[2021,7,1]],"date-time":"2021-07-01T12:03:27Z","timestamp":1625141007000},"page":"85","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Prototyping a Smart Contract Based Public Procurement to Fight Corruption"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2183-1052","authenticated-orcid":false,"given":"Tim","family":"Weing\u00e4rtner","sequence":"first","affiliation":[{"name":"School of Computer Science and Information Technology, Lucerne University of Applied Sciences and Arts, CH-6343 Rotkreuz, Switzerland"}]},{"given":"Danielle","family":"Batista","sequence":"additional","affiliation":[{"name":"Faculty of Arts, School of Information, University of British Columbia, Vancouver, BC V6T 1Z1, Canada"}]},{"given":"Sandro","family":"K\u00f6chli","sequence":"additional","affiliation":[{"name":"School of Computer Science and Information Technology, Lucerne University of Applied Sciences and Arts, CH-6343 Rotkreuz, Switzerland"}]},{"given":"Gilles","family":"Voutat","sequence":"additional","affiliation":[{"name":"School of Computer Science and Information Technology, Lucerne University of Applied Sciences and Arts, CH-6343 Rotkreuz, Switzerland"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,1]]},"reference":[{"key":"ref_1","unstructured":"World Economic Forum (2020).
