Method, device and system for transferring digital assets in block chains

Abstract

The invention provides a method, device and system for transferring digital assets in block chains. The method comprises the following steps: writing data involved in to-be-transferred digital assets in a state machine; generating asset issuing transaction according to the state machine and the digital assets; and broadcasting the asset issuing transaction in the block chains. By adoption of the method, device and system provided by the embodiment of the invention, when the digital assets are issued, the state transfer rule in a flow process is regulated, is recorded in the asset issuing transaction in the form of the state machine and is checked in the form of a consensus mechanism in a subsequent asset ownership transfer process, thereby ensuring that the assets generate state changes according to the rules regulated during the issuing and preventing the intermediary of asset transaction from randomly changing the states of the assets, and thus the accuracy and the integrity of the asset information recorded in the block chains in the flow process of the digital assets are guaranteed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for transferring digital assets in a block chain. Background technique [0002] Blockchain can store various digital assets and transfer asset ownership between different owners. However, there are often changes in the status of assets during the transfer process. For example, bills of exchange have various states such as application, acceptance, transfer, repurchase, etc., and stocks have states such as flow, freeze, and pledge. How to maintain the correct status of these assets during the asset circulation process? It is very important to ensure the accuracy and completeness of information during the flow of digital assets. [0003] For example, the information of a digital asset includes not only its owner, but also various state attributes of the digital asset. These states and state change history are closely related to the value of the di...

Problems solved by technology

It is precisely because the status information of digital assets is very important information, and these status changes are part of the market business rules. If a participant changes the status at will during the transfer process and does not abide by the market business rules, the digital assets will be It is damaged by itself and cannot guarantee the integrity of digital asset information

For example, if a participant directly modifies the bill in the "application" state to "acceptance" to apply for discounting, the history of this bill asset lacks the link of commercial bank acceptance, and the information in this bill asset is no longer complete. If you participate in the transaction, it will disrupt the trading market of digital assets
