A New One-time Address Scheme for Blockchain

One-time addresses have been an effective way to protect privacy of users in blockchain. However, most of existing one-time address schemes either consume extra storage for keys or are not quite efficient. To overcome these drawbacks, we proposed a new kind of one-time address scheme in which a user only needs to keep a single key pair. The proposed one-time address scheme reduces the storage of the key pairs and provides privacy for users in blockchain. Analysis and experiment results show that our scheme is efficient and secure as well.
