Distributed account book system based on layered structure

Abstract

The invention discloses a distributed account book system based on a layered structure. At least the defect that a traditional distributed account book system based on the layered structure is low in performance efficiency and is incapable of carrying out concurrence is solved. The system comprises multi-layer block chain network nodes. The multi-layer block chain network nodes comprise at least two items of the following items: a first-layer block chain network node, second-layer block chain network nodes attaching to the first-layer block chain network nodes, third-layer block chain network nodes attaching to the second-layer block chain network nodes, ......., Nth-layer block chain network nodes attaching to the (N-1)th-layer block chain network nodes. The N is a natural number greater than three. Each block chain network node further comprises a consensus subnode which is used for generating a corresponding consensus result message for a network transaction related to the block chain network node; and an account book subnode which is used for carrying out accounting according to the consensus result message generated by the consensus subnode.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a distributed ledger system based on a layered structure. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing paradigm that uses contracts to program and manipulate data. The blockchain technology itself has many advantages: on the one hand, because the blockchain network can realize self-restraint through algorithms, any behavior of maliciously deceiving the system will be repelled and suppressed by other nodes in the network. Therefore, a hierarchical structure-based The distributed ledger system can realize secure network transactions without relying on the support...

Problems solved by technology

Therefore, each blockchain node needs to participate in the consensus operation of all network transactions, resulting in a large system overhead for each blockchain node; moreover, each network transaction needs to go through the consensus of all blockchain nodes, resulting in each The efficiency of a network transaction is low; and, since the consensus operation of each transaction needs to be jointly participated by all blockchain nodes, multiple network transactions cannot be executed concurrently, which reduces the overall distribution based on a hierarchical structure. The transaction efficiency of the ledger system

[0005] Secondly, because the network transaction between any two blockchain nodes needs to be kept by all blockchain nodes, that is: the transaction account corresponding to the network transaction is recorded in the database jointly maintained by all blockchain nodes. Therefore, the data volume of the large ledger is relatively large, and the large ledger needs to be jointly maintained by each block chain node, which leads to a higher storage cost of the entire distributed ledger system based on a hierarchical structure. Large, and the bookkeeping and auditing efficiency is low

[0006] It can be seen that since the consensus operation and bookkeeping operation in a traditional distributed ledger system based on a layered structure need to be executed jointly by each blockchain node in the system, the entire system cannot be executed concurrently and the execution efficiency is low. low
