“…For closed interconnected systems, distributed system community has conducted extensive research on this, but its application in open blockchain has revitalized this field and led to a large number of new designs. Finally, the blockchain consensus protocol is systematically and comprehensively studied to meet this challenge [5]. Interconnected systems are maturing from the initial stage and becoming a part of the future Internet.…”

Blockchain, as the application of distributed computing and data storage, point-to-point transmission, encryption algorithm, consensus mechanism, and other technologies, has become an important hotspot of data technology in banks, securities, and other Internet enterprises. In view of the problems of delay and large throughput in the current intelligent interconnection system of block chain, this paper proposes an optimization method of intelligent interconnection of block chain technology, so as to improve the performance of the system. In this paper, firstly, the development of intelligent interconnection and the related concepts of intelligent interconnection system optimization are put forward. Then, the related algorithms of blockchain are proposed, including the consensus algorithm of blockchain and the throughput delay algorithm of blockchain. Finally, in the experimental part, the blockchain technology is deeply studied, and the advantages and internal structure of blockchain are clearly analyzed. Then, by comparing the consensus of blockchain to optimize intelligent interconnected system and comparing blockchain technology with ordinary technology to optimize intelligent interconnected system, it is concluded that blockchain plays a positive role in optimizing intelligent interconnected system and also promotes the optimization of intelligent system. Therefore, we should introduce the related technologies of blockchain into the optimization of intelligent interconnection system, and its blockchain technology analysis can make up for the shortcomings of intelligent interconnection system. It also shows that blockchain technology is suitable for many information research fields and plays an irreplaceable role. The blockchain system consists of six different hierarchies, mainly network data layer and blockchain consensus layer. The data layer mainly encrypts the data related to blockchain. The consensus layer recognizes the main algorithms of blockchain, which can encapsulate the network information nodes of blockchain. Therefore, when blockchain carries out relevant information analysis algorithms, it mainly relies on blockchain consensus algorithm. It is beneficial to analyze the complex information of the system and promote the optimal development of blockchain.

In the current trend of cloud storage and data sharing, image trading and consumption are increasingly frequent. Therefore, the protection of sensitive images and identity authentication become urgent. In this paper, an image sharing method based on 3-dimensional Boolean convolution neural network (3D-BCNN) and blockchain is proposed. Unlike traditional symmetric encryption algorithms, this paper introduces an asymmetric key cryptosystem, which allow different users to receive image with authorization without knowing the key of the data owner. The correctness authentication of the acquired image is based on blockchain, which is immutable and reliable. In pre-transmission encryption, 3D convolution matrices are designed by Chaotic Restricted Boltzmann Machine(CRBM), convolution kernel and shuffle rule are generated by novel two-parameters wide-range mapping mixed Coupled Map Lattice (TWM-CML), and each channel performs Boolean XOR convolution operation. The experimental simulation shows that the secret image has better security properties than the state-of-the-art algorithms. Furthermore, the algorithm provides an end-to-end trusted image protection system and authenticate efficiently.

With the rapid development of blockchain technology, the financial and monetary (FM) blockchain fields also began to collide. Therefore, this study aims to explore the relationship between the two fields and efficiently evaluate the security of financial information. Firstly, this study introduces the theoretical basis of blockchain in the dynamic linkage mechanism of FM and gives the overall framework of digital currency based on blockchain. Meanwhile, the relationship between blockchain and digital finance is empirically analyzed and designed. Secondly, the framework of financial information service security assessment (ISSA) is created using blockchain technology, and the frame of security risk evaluation is verified by taking electronic invoice information as the research object. Finally, the results show that: (1) foreign exchange (forex) events and major stock index decline events have a significant impact on the return of Bitcoin (BTC) in the short term. Moreover, more than 70% of uncertainty events will make BTC’s abnormal return (AR) significantly positive; (2) Under the influence of forex uncertainty events, only one BTC’s AR is remarkably negative in short order, while the other seven times are markedly positive. In the uncertainty events of major stock indexes, only two times are significantly negative, and the other six times are positive. This indicates that uncertain events in the short run make prominent AR of BTC; the proposed blockchain-based ISSA model and assessment index are scientific, feasible, and operable.
