Embodiment Construction

[0043] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0044] figure 1 It is an application environment diagram of the blockchain-based single-node bookkeeping method in an embodiment. refer to figure 1 , the blockchain-based single-node bookkeeping method is applied to the blockchain network 100. The blockchain network 100 includes core nodes 102 and edge nodes 104 . Such asfigure 1 As shown, there are multiple core nodes 102 and edge nodes 104 in the blockchain network 100 . The core node 102 may serve as an accounting node or a backup node, and the edge node 104 may also serve as an accounting node or a backup node. Ed...

Abstract

The invention relates to a single-node bookkeeping method, system and device based on a block chain and a storage medium. The method comprises the steps that an accounting node initiates a backup request, wherein the backup request is used for indicating a core node in a block chain network, and a plurality of backup nodes are selected from the block chain network according to the backup request and a corresponding block identifier after the backup request is recorded to a traditional block chain; the accounting node acquires a plurality of backup nodes and establishes network connection witheach backup node; when the target data is obtained, the accounting node triggers to generate a corresponding target block, and records the target block to a single-node accounting block chain corresponding to the accounting node, wherein the target block comprises a block hash value of the previous block, a data hash value of the target data and a digital signature corresponding to the block hashvalue and the data hash value; and the accounting node sends the target block to the corresponding backup node for backup through network connection. By adoption of the method, the transaction quantity per second can be increased under the condition that the data reliability and non-tampering performance are ensured.

Description

technical field [0001] The present application relates to the technical field of block chain, in particular to a single-node bookkeeping method, system, device and storage medium based on block chain. Background technique [0002] In the existing blockchain technology, the blockchain network selects bookkeeping nodes through a consensus mechanism, and packages the legal transaction data verified by each node into blocks and records them in the blockchain to ensure that the transaction data cannot be tampered with. . However, this accounting method has high requirements on network transmission, node computing and data storage capabilities, and has relatively large restrictions on TPS (Transactions per second, the number of transactions per second) and transaction data volume. Especially in the application scenarios of high-frequency and large-capacity data storage, this accounting method further increases the requirements for network transmission, node computing and data sto...
