Embodiment 1

[0013] This embodiment provides a system for testing the validity of entries in a database data structure, which is characterized in that the system includes: at least one blockchain node server receives a signal from a client system to register in the database data structure Event, the database data structure includes a blockchain, which in turn includes a series of blocks linked sequentially, so that each block encodes at least part of the state information of the previous block; used for the blockchain after the initial block At least the selected block includes a representation of the historical hash tree with the highest-level root value, and as the lowest-level input, a device for leaf input values ​​derived from the block-specific information stored therein. At least one before the block-specific block, the block-specific information encoding corresponds to the data of each event included in the corresponding block, and is used to calculate the result by paired function c...

Embodiment 2

[0022] This embodiment again proposes a system for testing the validity of entries in a database data structure, which is characterized in that the system includes: at least one blockchain node server receives a signal from a client system to register in the database data structure Event, the database data structure includes a blockchain, which in turn includes a series of blocks linked sequentially, so that each block encodes at least part of the state information of the previous block; used for the blockchain after the initial block At least the selected block includes a representation of the historical hash tree with the highest-level root value, and as the lowest-level input, a device for leaf input values ​​derived from the block-specific information stored therein. At least one before the block-specific block, the block-specific information encoding corresponds to the data of each event included in the corresponding block, and is used to calculate the result by paired func...

Embodiment 3

[0032] In this embodiment, it first builds a system for testing the validity of entries in the database data structure, including: at least one blockchain node server receives a signal from the client system to register events in the database data structure, so The database data structure includes a blockchain, which in turn includes a series of blocks linked sequentially, so that each block encodes at least part of the state information of the previous block; it is used for at least all of the blockchain after the initial block. The selected block includes a representation of the historical hash tree with the highest-level root value, and as the lowest-level input, a device for leaf input values ​​derived from the block-specific information stored therein. At least one before the block-specific block, the block-specific information encoding corresponds to the data of each event included in the corresponding block, and is used to calculate the result by paired function combinati...

Abstract

The invention provides a system for testing validity of entries in a database data structure. The system for testing validity of entries in database a data structure is characterized in that: the system comprises at least one block chain node server that receives a signal from a client system to register an event in the database data structure, wherein the database data structure comprises a blockchain, and the block chain comprises a series of blocks sequentially linked, so that each block encode at least partial state information of a previous block; and the system comprises a device whichis used for representing a historical hash tree having a highest level root value in at least a selected block of the block chain after the initial block, and as a lowest level input device inputtingleaf input values derived from block specific information stored therein.

Description

Technical field [0001] The invention relates to the field of distributed computing, and in particular to a system for testing the validity of entries in a data structure of a blockchain database. Background technique [0002] Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm that realizes the establishment of trust between different nodes and the acquisition of rights and interests in the blockchain system. Generally speaking, the blockchain system is composed of data layer, network layer, consensus layer, incentive layer, contract layer and application layer. Among them, the data layer encapsulates the underlying data blocks and related data encryption and time stamping and other basic data and basic algorithms; the network layer includes distributed networking mechanisms, data propagation mechanism...
