Optimized scalable Byzantine fault tolerance algorithm by Sicheng HAN, Xiaorong ZHU, Xiuxian ZHANG

“…Blockchain is a decentralized ledger which provides trust to both parties which distrust each other in a transaction.Blockchain initially served as the underlying framework that underpins bitcoin and has increasingly become a disruptive new technology in recent years.Consensus algorithm is one of the core technologies of blockchain.Without a consensus algorithm,the state consistency among distributed nodes cannot be achieved.The practical Byzantine fault tolerance (PBFT) algorithm was briefly introduced,which was a commonly used consensus algorithm in consortium blockchain.An optimized and scalable algorithm based on it was proposed.The improved algorithm mainly reduced the algorithm complexity and allowed consensus nodes to join and exit the system.Simulation results show that the improved algorithm can significantly reduce the transaction consensus completion time and the number of communication times between nodes,so as to increase the throughput of the whole system while supporting more nodes and reducing the system communication overhead and CPU computing resource consumption.…”

Proxy-cryptocurrency payment system by Xiao-tong FU, Si CHEN, Ning ZHANG

“…The decentralized cryptocurrency which was based on block chain has been thought the most successful one in history.In the system,public keys were used as the users’ accounts which guaranteed the anonymity in real transactions.However,all the transaction information was recorded in the block chain,it was a potential threat for users’ privacy which might leak the payment information.Moreover,to avoid double-spending,it was agreed that the transaction on the target block was valid only if another k blocks were generated after the target one.The long waiting time reduced the efficiency of the payment system.A model of payment system based on a proxy-cryptocurrency was proposed,and a solution based on blind signature techniques was proposed.The scheme introduced a proxy in the payment phase,by which transaction confirmation time could be reduced and the transaction efficiency could be improved.Meanwhile,the system implements better anonymity,namely as the privacy protection function.…”

Multi-party efficient audit mechanism for data integrity based on blockchain by Jiashun ZHOU, Na WANG, Xuehui DU

“…A blockchain-based data integrity multi-party high-efficiency audit mechanism (MBE-ADI) for the big data environment was proposed.A hybrid Merkle DAG structure based on data domain was built to organize data, and realized the simultaneous verification of a large number of unstructured data in the big data environment.In order to deal with the problem of large amount of data in the big data environment, a multi copy deterministic verification method based on BLS signature was designed to realize the efficient verification of data integrity supporting multiple copies.A dual verification audit architecture based on consortium blockchain was designed to realize decentralized automatic audit and audit history credible traceability.At the same time, data integrity verification services were provided for data owners and data users to realize reliable acquisition of data.The test proves the feasibility of the system and the efficiency of data integrity audit.…”
