However, the protection of bidders\u2019 privacy, transaction fairness and verifiability, transaction data security, high cost of third-party auction center, and other issues have attracted more attention. According to the transaction process and basic principles of the sealed auction, we explored the problems existing in the current sealed-bid e-auction schemes. Based on the blockchain technology, we proposed a sealed-bid e-auction scheme with smart contract technology, Bulletproofs zero-knowledge proof protocols, and Pedersen commitment algorithm. The proposed scheme constructed an auction mechanism without the third-party auctioneer so as to restrict the behaviors of auction parties for the sake of auction security, reliability, fairness, and privacy protection. Compared with the related sealed e-auction schemes based on blockchain technologies in six metrics, we conducted the experiment to show that the proposed scheme protected the bid information from leakage well and successfully verified the winning bid price and the related bidder by all transaction participants without the third-party auctioneer.<\/jats:p>","DOI":"10.1155\/2021\/5523394","type":"journal-article","created":{"date-parts":[[2021,5,20]],"date-time":"2021-05-20T00:20:06Z","timestamp":1621470006000},"page":"1-10","source":"Crossref","is-referenced-by-count":14,"title":["A Blockchain-Based Sealed-Bid e-Auction Scheme with Smart Contract and Zero-Knowledge Proof"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7080-873X","authenticated-orcid":true,"given":"Honglei","family":"Li","sequence":"first","affiliation":[{"name":"School of Government, Liaoning Normal University, Dalian, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4639-2663","authenticated-orcid":true,"given":"Weilian","family":"Xue","sequence":"additional","affiliation":[{"name":"School of Government, Liaoning Normal University, Dalian, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1002\/dac.4547"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/mnet.001.1900660"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1002\/9781119621201.ch2"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/access.2019.2961372"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/access.2020.2970576"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/32.502223"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1007\/11507840_26"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1007\/s10207-006-0001-y"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1007\/11889663_10"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1007\/s10796-008-9094-3"},{"issue":"20","key":"11","first-page":"140","article-title":"Electronic auction scheme based on trustless third-party","volume":"36","author":"G.
