N2 - A majority of electronic bartering transactions is carried out via online platforms. Typically, these platforms require users to disclose sensitive information about their trade capabilities which might restrict their room for negotiation. It is in this context that we propose a novel decentralized and privacypreserving bartering protocol for multiple parties that offers the same privacy guarantees as provided by traditional bartering and by cash payments. The proposed protocol is even secure against an active attacker who controls a majority of colluding parties.
