Abstract

The invention discloses a cross-block chain digital asset transfer method and device; the method comprises the following steps: receiving a transfer application requesting to transfer first quantity digital asset from a user party node in the first block chain to a receiver party node in a second block chain; responding to the received transfer application, and invoking an agreed intelligent contract program between the first and second block chains; equivalently converting the first quantity digital asset into the second quantity legal general data according to the invoked intelligent contract program; writing a digital asset record deducting the first quantity into the first asset database of the user party node, and writing a legal general data record adding the second quantity into the second asset database of the receiver party node. The method and device can ensure the digital asset total quantity remaining unchanged in a different block chain transfer process, thus preventing transfer losses, ensuring fast transfer, and preventing participation party fake voting problems.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for cross-blockchain digital asset transfer. Background technique [0002] With the development of communication technology, blockchain is gradually being applied to data processing application scenarios due to its advantages of openness, transparency, and immutability. The blockchain can be regarded as a distributed unified ledger. All participants jointly determine the accounting content. Each participant has a full amount of data, and any individual participant cannot tamper with the data. Blockchain technology is a general technology. The blockchain can be, for example, the Bitcoin blockchain or the Ethereum blockchain. Digital assets or digital currencies registered on different blockchains will have a demand for circulation. For example, if a user wants to exchange Bitcoin for digital assets on Ethereum, traditionally he can only conver...
