We propose Lelantus, a new anonymous payment system which ensures both transactional confidentiality and high anonymity with small proof sizes, short verification times and without requiring a trusted setup. We show how to support efficient aggregation of the transaction proofs, so that the proof verification, while asymptotically linear, is very efficient in practice. Lelantus builds on the techniques of Con fidential Transactions, Zerocoin, and 1-out-of-Many proofs and its efficiency is particularly well-suited for enabling private blockchain transactions with minimal trust required while employing well-studied cryptographic assumptions. Aram is a cryptographer at Zcoin and the founding CEO of Skycryptor, Techstars company pioneering the development of proxy re-encryption algorithms. At Zcoin Aram has invented the Lelantus protocol and now is working on scaling it to the next level. Before founding Skycryptor Aram was a senior cryptography researcher and development team lead at the American University of Armenia where the scientific group conducted cryptography research for big industrial partners.
