“…Proactive reconfigurable computers use dynamic randomicity to build an asymmetric defense system, which expands the attack surface to weaken intrinsic attacks of feature sniffing and state transition [11]. Based on such a characteristic, 10,000 Mbp communication is realized by using FPGA to reduce data transmission delay, build a simulated hash structure, and improve the speed of hash value calculation of blockchain data.…”

Blockchain is widely used in encrypted currency, Internet of Things (IoT), supply chain finance, data sharing, and other fields. However, there are security problems in blockchains to varying degrees. As an important component of blockchain, hash function has relatively low computational efficiency. Therefore, this paper proposes a new scheme to optimize the blockchain hashing algorithm based on PRCA (Proactive Reconfigurable Computing Architecture). In order to improve the calculation performance of hashing function, the paper realizes the pipeline hashing algorithm and optimizes the efficiency of communication facilities and network data transmission by combining blockchains with mimic computers. Meanwhile, to ensure the security of data information, this paper chooses lightweight hashing algorithm to do multiple hashing and transforms the hash algorithm structure as well. The experimental results show that the scheme given in the paper not only improves the security of blockchains but also improves the efficiency of data processing.
