Research On Blockchain Architecture Based On Domestic Cryptographic Algorithms

As a disruptive revolutionary technology,blockchain has developed rapidly in the world,and chinese research on blockchain is at the forefront of the world.However,there is also the problem in some scientific research fields in China.In the blockchain technology,because it adopts the international common cryptographic algorithms as its security module,the current blockchain architecture lacks autonomous controllability,which restricts the development of blockchain technology in China.The security,stability and independent controllability of domestic cryptographic algorithms can make up for the defects of blockchain cryptographic algorithms.Therefore,this paper proposes a blockchain architecture based on the domestic cryptographic algorithms--"Domestic cipher chain".The domestic cryptographic algorithm SM2 and SM3 are used to replace the ECC and sha-256 of the international common cryptography algorithm.At the same time,according to the current situation of consensus algorithm compromise in blockchain architecture,the "pluggable consensus" protocol is designed,which solves the unchangeable problem of consensus algorithm in blockchain architecture.The experimental results show that "Domestic cipher chain" and ordinary blockchain architecture have higher consensus efficiency and lower resource cost under the condition of similar consistency and effectiveness."Blockchain architecture based on domestic cryptographic algorithms" is a set of blockchain as the storage medium and basic network architecture,and the core technology blockchain cryptographic algorithm,password technology replaced by domestic cipher chain architecture model,its main purpose is through the algorithm to replace general cipher algorithm,in the currency in concise and efficient at the same time,ensure blockchain function realizes automatic blockchain safe and controllable,is a blockchain technology and domestic password technology with the combination of science and technology innovation.
