Problems solved by technology

However, the small number of terminal computers and the characteristics of private creation mean that the trustworthiness (non-repudiation) of private blockchains is not as good as that of public blockchains, and the scope of application of private blockchains is relatively narrow

Embodiment Construction

[0064] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0065] Please refer to figure 1 , figure 1 It is a schematic block diagram of a verification system 10 according to an embodiment of the present invention. In this embodiment, the verification system 10 is suitable for cooperating with the blockchain BC, and the blockchain BC may include a public blockchain, a private blockchain or a combination thereof. The verification system 10 is used to communicate and connect multiple terminal devices 400 in the off-chain OC (off-chain channel), and to cooperate between the blockchain BC and the off-chain OC, and Each terminal device 400 can generate at least one record data RD. The off-chain OC refers to a path independent of the block chain BC, and the off-chain OC communication connection refers to a communication connection on a path independent of the block chain BC. For example,...

Abstract

A verification system and method for cooperating with a blockchain and off-chain device is provided. The system includes a security protocol device, a blockchain device, and a database device. The security protocol device receives and integrates the record data into a binary tree according to a hash function. Hash values of the record data are stored in the leaf nodes. The blockchain device is atthe blockchain and communicates with the security protocol device. The security protocol device transmits the root hash to the blockchain device. The database device communicates with the security protocol device in an off-chain manner. The security protocol device stores the binary tree to the database device. The security protocol device compares the root hash from the blockchain device with theroot hash of the binary tree stored in the database device to verify the correctness of the binary tree stored in the database device.

Description

technical field [0001] The present invention relates to a verification system, and in particular to a verification system and method suitable for cooperation between blockchain and off-chain. Background technique [0002] In the existing technology, the blockchain (blockchain) adopts a decentralized architecture to achieve the purpose of decentralization. Terminal computers all over the world can be connected through the blockchain, and any terminal computer transmits data to the blockchain. The data can be distributed in other terminal computers on the blockchain through a specific calculation method. Since these data exist in a large number of terminal computers on the blockchain, the correctness of the data can be verified by a large number of terminal computers in the blockchain, which makes it difficult for the blockchain data to be altered or tampered with. [0003] In the traditional terminal computer-to-central server architecture, when a terminal computer wants to ...
