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 solution 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 It shows an embodiment of setting up a hosting smart contract on the blockchain main chain that can transfer virtual resources to and from the side chain, that is, setting up corresponding hosting smart contracts for different side chains, such as side chains on the main chain 1 Set up escrow smart contract 1, set up escrow smart contract 2 for sidechain 2. Regarding the establishment and release of the escrow smart contract, after the side chain registration is completed and the side chain id...

Abstract

The invention provides a virtual resource transfer method, which is applied to a decentralized system comprising a block chain side chain and a main chain. The method comprises the following steps: the main chain issues a trusteeship smart contract; when a virtual resource is transferred from the main chain to the side chain, a virtual resource sender sends an account transfer instruction to the trusteeship smart contract; when the virtual resource is transferred from the side chain to the main chain, a miner who obtains the billing right of a main chain block sends transaction information tothe trusteeship smart contract and records the transaction information to the main chain block; and the trusteeship smart contract is internally provided with a voting mechanism, and when voting of the miner who obtains the billing right of the block for the same transaction is met, the trusteeship smart contract initiates payment. The main chain issues the smart contract for trusteeship of the virtual resources of the side chain, so that balance of the virtual resources of the side chain can be managed effectively.

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...
