Problems solved by technology

Existing solutions for synchronizing information and data among lightweight node groups include a combination of device and cloud solutions, in which lightweight nodes with strong correlations form a small network through a local area network. In a large-scale blockchain system, each node in the system saves the blockchain ledger of the system. In this solution, for each lightweight node cluster blockchain system, the cloud side needs to provide A consensus instance to participate in the consensus process of its block generation, that is, it needs to provide services, track the block generation inside its node cluster in real time, and synchronize in time. This solution has a large overhead on the cloud side
On the other hand, this solution cannot guarantee that the blockchain data stored on the cloud side cannot be tampered with
When the data of the node group is lost, the cloud side can completely forge and modify the data on it, and the node cluster has no mechanism to verify the data provided by the cloud side

Embodiment Construction

[0053] Embodiments of the present application are described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Those of ordinary skill in the art know that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0054] The embodiment of the present application provides a communication method, a node and a storage medium. The cloud node builds a comprehensive block according to the received shared information of different node clusters, so as to achieve low overhead, high efficiency, reliability, and non-tamperable data transmission within the node cluster. and the purpose of sharing are described in detail below.

[0055]The terms "first", "second" and the like in the specification and claims of the prese...

Abstract

The invention discloses a communication method, which can be suitable for a home Internet of Things, and comprises the following steps: a third node receives a first block sent by a first node, and the first block can comprise first block data; and the third node receives a second block sent by the second node, the second block can comprise second block data, and the first block and the second block are blocks in a block chain maintained by different node clusters. The third node generates a third block according to the received first block and second block, the third block can include the first block data, the second block data and a hash value of the third block, and the hash value of the third block is determined according to the first block data and the second block data. According tothe technical scheme provided by the invention, the reliability and the non-tampering performance of the information of each node cluster are ensured, and the purpose of carrying out data transmissionand sharing in the node cluster in a low-overhead, efficient, reliable and non-tampering manner is achieved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method. Background technique [0002] The blockchain network is a network that realizes information storage and transmission based on blockchain technology. With the further expansion of the blockchain application industry, the data generated by equipment will grow explosively. Since the current blockchain network maintains the information of the entire ledger, the explosive growth of data will cause a large load on the blockchain network, and the transmission of the blockchain in the blockchain network will also consume huge bandwidth. [0003] With the advancement of blockchain technology and the needs of application scenarios, the concept of lightweight nodes has gradually emerged. The difference between lightweight nodes and full nodes is that only part of the blockchain data is stored, thereby reducing the requirements for node hardware e...
