Lelantus: Private transactions with hidden origins and amounts based on DDH

Aram Jivanyan

Abstract: We propose a new protocol for private financial transactions on the blockchain which ensures the privacy of both transaction values and their origins without a trusted setup. By combining different techniques from the confidential transaction protocol of Greg Maxwell, the Zerocoin Protocol and One-out-of-Many Proofs of Groth et al., we propose a new system, Lelantus, that provides both anonymity and confidentiality of transactions.
