Abstract
Systems and methods for anonymous cryptocurrency transactions are disclosed. A method may include: receiving, from the electronic device associated with a sender of a cryptocurrency transaction, a zero-knowledge statement comprising a shuffled and anonymized list of participants comprising the sender, a receiver of the cryptocurrency transaction, and a plurality of decoy participants, a transfer amount, and a remaining balance, and a secret witness, wherein each participant is associated with an index; generating one-out-of-many proofs for the sender and the receiver based on their associated indices; generating a Basic Zether proof for the transfer amount and the remaining balance; conducting many-out-of-many proofs with parameters chosen for an anonymous payment setting; and constructing a zero-knowledge proof for the zero-knowledge statement. The sender sends an ordered list of the participants and the zero-knowledge proof to a verifier using the FiatShamir transform, and the verifier verifies the zero-knowledge proof.
