Abstract

Cross-chain technology is essential for achieving blockchain scalability and interoperability. This paper presents a cross-chain scheme combining notary with linkable ring signatures and the hash time lock contract. The scheme uses linkable ring signatures to act in the notary election process, which prevents duplicate voting and ensures the anonymity of voting nodes to prevent user information leakage. In this paper, a notary group is employed to oversee and engage in cross-chain transactions, which reduces the centralization of notaries’ power. In addition, this paper examines the election procedure of the notary and the cross-chain transaction process of this scheme and illustrates the security and effectiveness of this scheme.
