چکیده
In a competitive market, online auction systems enable optimal trading of digital products and services. Bidders can participate in existing blockchain-based auctions while protecting the confidentiality their bids decentralized, transparent, secure, auditable manner. However, parties would prefer not to disclose interests competitors, remain anonymous during auctions. this paper, we firstly analyze specific requirements for fair We present formal model tailored study that facilitate anonymity, as well generic protocol achieving bid bidder anonymity using cryptographic primitives such designated verifier ring signature. demonstrate it is secure security presented. Towards end, through extensive simulation results on Ethereum blockchain proposed practical has minimal associated overhead. Furthermore, discuss complexity vulnerabilities environment might introduce implementation.

متن کاملFive Sealed-bid Auction Models
Published sealed-bid auction schemes are classi ed into four models according to how they deal with bid privacy. The properties of each model are introduced and possible improvements in these models are suggested. A new model is proposed and its implementation is discussed. Application of di erent models is discussed, based on a comparison of the models.
متن کاملAnonymous sealed bid auction protocol based on a variant of the dining cryptographers' protocol
Sealed bid auctions are a popular means of high-stakes bidding, as they eliminate the temporal element from the auction process, allowing participants to take less emotional, more thoughtful decisions. In this paper, we propose a digital communication protocol for conducting sealed bid auctions with high stakes, where the anonymity of bids as well as other aspects of fairness must be protected....
متن کاملA Market-Affected Sealed-Bid Auction Protocol
Multiagent resource allocation defines the issue of having to distribute a set of resources among a set of agents, aiming at a fair and efficient allocation. Resource allocation procedures can be evaluated with regard to properties such as budget balance and strategy-proofness. Designing a budget-balanced and strategy-proof allocation procedure that always provides a fair (namely, envyfree) and...
