Abstract

We present a general fault-tolerate multiparty contract signing protocol that uses verifiable signature sharing technique, the protocol works in the asynchronous network environment and realizes multiparty contract signing within a fixed expected number of computational rounds. The correctness of the protocol is proved in theory.
