Problems solved by technology

[0010] The above solutions are optimized specifically for the blockchain, and do not take into account the special network environment of the Internet of Vehicles. Because of the high dynamics of the nodes of the Internet of Vehicles, these solutions are not fully applicable to the Internet of Vehicles environment.

Embodiment Construction

[0064] The specific embodiments of the present invention are described below to facilitate those skilled in the art to understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes Such changes are obvious within the spirit and scope of the present invention as defined and determined by the appended claims, and all inventions and creations utilizing the inventive concept are within the scope of protection.

[0065] The solution of the present invention is mainly divided into three steps, namely block coding, block recovery, and block verification. The three complement each other and jointly build a set of secure and lightweight blockchain block storage methods suitable for the Internet of Vehicles. Through the scheme of the present invention, the block is encoded and stored in the RSU by slice, and when the block recovery is required, it is on...

Abstract

The invention discloses a block storage method of a lightweight block chain of the Internet of Vehicles, which comprises the following steps: S1: constructing a block chain storage architecture model to generate blocks; S2: using a block coding algorithm to store the blocks Encoded into several encoding blocks, and randomly sent to each node in the network, S3: several encoding blocks are stored in the RSU, S4: merge the corresponding codes into blocks, S5: verify the integrity of the merged blocks and correctness. The storage architecture model of the block storage method includes: blockchain layer, coding layer, core layer, aggregation layer, verification layer and edge layer. The present invention proposes a novel block coding scheme based on LT fountain coding. This solution enables nodes to function as complete nodes even when only a part of the blockchain is stored, so that the security of the entire blockchain network is not affected.

Description

technical field [0001] The invention relates to the technical field of blockchain, in particular to a block storage method and model of a lightweight blockchain of the Internet of Vehicles. Background technique [0002] Every node in the blockchain network keeps all the block information, which will take up a lot of storage space. Taking virtual currency as an example, 661,743 blocks have been generated, and a single node needs to store 294.58GB of block data, and this data will still grow gradually over time. This feature of the blockchain leads to the following two problems: [0003] Each node takes up a lot of storage space; [0004] The scalability of the entire network is limited, and new nodes need to synchronize a large amount of data from the network when joining. [0005] These problems are further magnified in the Internet of Vehicles, because there are a large number of storage and performance-constrained in-vehicle devices in the Internet of Vehicles, which ar...
