Abstract
The amazing rise of digital currency is not only favored by investors but also attractive to lawbreakers for its anonymity and decentralization. This paper mainly discusses the intelligent digital currency and dynamic coding service system based on Internet of Things technology. In this paper, the RDCAR algorithm is used to realize the routing discovery process of the wireless network. When the intermediate node receives the RREQ message, first of all, to avoid the loop, it checks whether the same RREQ message has been introduced. If it has received it, it will discard it. Otherwise, it will cache the message and attach its own neighbor node list to the signal-to-noise ratio of the channel link, update the RREQ message, and broadcast it. The payment cipher is managed by the bank. When the user opens an account, the bank registers and sends it to the user. The key is generated by the algorithm chip, and the public key is kept in the bank background server. When the bill is delivered to the bank, the bank inputs all the elements on the bill on the counter terminal and transmits it to the verification machine for verification through the bank network. If the verification is correct, it indicates that the bill is indeed issued by the customer, and all bill elements are correct, and payment can be made. The node operation protocol of public chain and alliance chain maintains the operation of the Internet of Things system. The nodes of alliance chain generate new blocks according to the interval of 30 s. When the node fails to complete the block generation within 30 s, it will rotate to the next node. The mkfile command is used to generate 16b, 1 KB, 1 MB, and 1 GB files as input. The peak speed of the encoding service system is about 370 mb/s. The results show that the system designed in this study is robust and suitable for complex trading environment.
Highlights
With the rise of the wave of digital currency in recent years, some underlying technologies related to it, such as blockchain technology and distributed accounting methods, show broad application prospects
When the node cannot complete the block generation within 30 s, it will rotate to the node
System initialization completes the generation of system parameters and the initial state of the blockchain; transaction verification and forwarding are the process of sharing information among alliance chain members, ensuring that nodes reach consensus on the same basis; the consensus process includes the specific process of node interaction in CPBFT; transaction confusion is responsible for after the transaction is confirmed, and the transaction is processed before being sent to the public chain node to remove the transaction relationship information to protect transaction privacy; the final transaction traceability is the process of internal supervision of the system. e communication between nodes in the alliance chain uses encrypted channels to prevent information leakage when the communication transmits the plaintext and completes transactions
Summary
With the rise of the wave of digital currency in recent years, some underlying technologies related to it, such as blockchain technology and distributed accounting methods, show broad application prospects. Ey gave a comprehensive overview of the Internet of ings in terms of system architecture, supporting technology, security, and privacy issues and studied the integration of fog/edge computing with the Internet of ings and applications. Yaqoob et al discussed the architecture of the Internet of ings In this case, first of all, they investigate, focus on, and report on the recent major research progress in the IoT architecture and classify the IoT architecture and design a taxonomy based on important parameters (such as applications, supporting technologies, business goals, architecture requirements, network topology, and IoT platform architecture types). Ey identified and outlined the key requirements of the future IoT architecture and discovered and introduced some outstanding case studies on the Internet of ings They listed and outlined the future research challenges. When the node cannot complete the block generation within 30 s, it will rotate to the node
