Block chain system-based digital asset transaction method and block chain system

Abstract

The invention discloses a block chain system-based digital asset transaction method and a block chain system. The block chain system is a tree-shaped distributed block chain system including a plurality of levels of block chains. The method comprises the following steps that: a first block chain receives a digital asset transaction request from a client, and determines digital assets corresponding to the digital asset transaction request; whether an attribution block chain corresponding to the digital assets is a first block chain is judged; if the attribution block chain corresponding to the digital assets is the first block chain, the first block chain processes the digital asset transaction request; and if the attribution block chain corresponding to the digital assets is not the first block chain, the first block chain rejects the digital asset transaction request, wherein the attribution block chain corresponding to the digital assets is a block chain that generates the digital assets. The method is especially suitable for the transactions of one-time one-use digital assets, wherein the digital assets can be only used once; and moreover, the method can also realize a cross-chain transactions between the digital assets, and the digital assets are corresponding to different attribution block chains before and after the cross-chain transactions are executed, and therefore, the security of the assets can be improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a digital asset transaction method and a blockchain system based on a blockchain system. 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, the blockchain system does not need to rely on Secure network transactions can be realized with the ...

Problems solved by technology

[0003] However, most of the traditional blockchain systems are implemented using a decentralized distributed architecture. Each network transaction needs to pass the consensus operation of all blockchain nodes in the system to take effect, and the transaction needs to be recorded in all blockchain nodes. On the large ledger of the system jointly maintained by the block chain nodes

However, the inventor found in the process of realizing the present invention that there are at least the following problems in the prior art: when using the block chain system to realize the transaction of digital assets, each digital asset transaction process needs to be controlled by the block chain system. Therefore, not only is it inefficient, multiple transactions cannot be executed concurrently, but it also increases the risk of digital assets being attacked by malicious nodes
