Problems solved by technology
[0003] However, most of the existing decentralized systems including blockchain main chain and side chain can only complete the one-way transfer of assets from the main chain to the side chain; moreover, since the asset transfer process on the side chain is not controlled by the main chain Chain monitoring, asset transfer fraud is very easy to occur on the side chain, especially when the side chain rolls back, it is easy to generate "double spending" transactions on the side chain

Embodiment Construction
[0026] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] In order to solve the two-way transfer of assets between the main chain and side chains, and avoid transaction fraud or double payment on the side chains, the present invention provides a method and device for asset transfer between blockchain chains. figure 1 and figure 2 The interface embodiments between the blockchain main chain and the side chain that can transfer virtual resources to each other are illustrated respectively. The interface described in the present invention is the direct connection point between the main chain and the side chain, and the main chain and the side chain can transmit information or transfer virtual resources through this interface; the interface can be connected to only one side chain or multiple side chains chain...

The invention provides a virtual resource transfer method, and the method is used for a decentration system which comprises a blockchain side chain and a main chain. The main chain is provided with aregistered unique identifier of an interface between the side chain and the main chain. The method comprises the step that a first virtual resource sender transmits a content which comprises the account information of the first virtual resource sender at the main chain, the unique identifier of the interface, the account information of the first virtual resource sender at the side chain and a first virtual resource transfer amount to the blockchain main chain when the first virtual resource is transferred to the side chain from the main chain. According to the invention, the unique identifierof the interface between the side chain and the main chain is registered on the main chain, and the side chain identity and account address information is built, thereby building a bridge for the transfer of the virtual resource from any account of the main chain to any account of the side chain.
Description
technical field [0001] The invention relates to the field of information technology, in particular to a method and device for virtual resource transfer in a blockchain-based decentralized system. Background technique [0002] A sidechain is a special kind of blockchain that usually uses a technology called "SPV wedge" to transfer assets between other blockchains, which allows users to use existing assets to use new encryption monetary system. By inheriting and reusing a powerful blockchain main chain (such as the Bitcoin blockchain), problems such as liquidity shortages and market fluctuations of new currencies are also avoided; and since the sidechain is an independent and isolated system, the sidechain Serious problems in the chain will only affect the sidechain itself, which greatly reduces the risk and cost of innovation. [0003] However, most of the existing decentralized systems including blockchain main chain and side chain can only complete the one-way transfer of...
