Digital asset transaction method and blockchain system based on blockchain system

Abstract

The invention discloses a digital asset transaction method and a blockchain system based on a blockchain system. Wherein, the block chain system is a tree-shaped distributed block chain system including block chains of multiple levels, and the method includes: the first block chain receives the digital asset transaction request from the client, and determines that it corresponds to the digital asset transaction request digital assets; determine whether the attribution block chain corresponding to the digital asset is the first block chain; if so, the first block chain processes the digital asset transaction request; if not, the first block chain rejects the digital asset transaction request; wherein, the attribution blockchain corresponding to the digital asset is the blockchain that generated the digital asset. This method is especially suitable for one-time digital asset transactions, which can only be used once; moreover, this method can also realize cross-chain transactions between digital assets, and the digital assets before and after the execution of cross-chain transactions correspond to different Belonging to the blockchain, thus improving the security of assets.

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
