主　　题：security blockchain signature consortium interactive proof 

摘      要：The blockchain is a radical innovation that has a considerable effect on payments,stock exchanges,cybersecurity,and computational ***,its limitations in terms of the uncertainty involved in transaction confirmation are *** this paper,we describe the design of a decentralized voting protocol for the election of a block generator in a consortium blockchain and propose a new system framework that allows fast and exact confirmation of all *** addition,to replace a transaction’s owner signature,a new interactive incontestable signature between the dealer and owner is used to confirm a *** means of this signature,the dealer can assure the owner that a transaction will be permanently included in the blockchain in a non-repudiation ***,the signatures of all transactions in a block share only one witness that provides membership proof between the block and these ***,a security and performance analysis shows that the proposed schemes are provably secure and highly efficient.
