Detailed Description
The invention is described in further detail below with reference to specific embodiments and the attached drawing figures. Those skilled in the art will be able to implement the invention based on these teachings. Moreover, the embodiments of the present invention described in the following description are generally only some embodiments of the present invention, and not all embodiments. Therefore, all other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative effort shall fall within the protection scope of the present invention. Unless otherwise specified, the methods described in the examples of the present invention are all those known to those skilled in the art.
Example 1
The embodiment provides a non-homogeneous asset cross-chain transaction method, which is applicable to a blockchain system, where the blockchain system at least includes a first blockchain and a second blockchain, where one of the first blockchain and the second blockchain is a main chain and the other is a parallel chain, and both the first blockchain and the second blockchain are deployed with a non-homogeneous asset cross-chain transaction contract, and in general, a non-homogeneous asset has some fixed attributes to ensure its non-homogeneous characteristics, such as a unique ID in the blockchain system, an issuer, and the like, and none of these clients can modify.
The method comprises the following steps:
obtaining a first transfer transaction initiated on a first blockchain for transferring a first asset across the chain, the first transfer transaction comprising fixed attribute information and ownership information of the first asset;
according to the first transfer transaction, calling a non-homogeneous asset cross-chain transaction contract of the first block chain to generate a first transaction instruction, wherein the first transaction instruction is used for modifying the state identifier and the owner of the first asset or destroying the first asset; the method of modifying the status identification and owner of a first asset or destroying the first asset comprises: judging whether the first asset is a derived asset or a native asset, destroying the first asset if the first asset is the derived asset, modifying the state identifier of the first asset into a logout state if the first asset is the native asset, and setting the owner of the first asset as a non-homogeneous asset cross-chain trading contract; the primary asset is a non-homogeneous asset formed in a current blockchain and the derived asset is a non-homogeneous asset cast by the primary asset transferring across the chain.
The first transfer transaction is synchronized to a second block chain based on the non-homogeneous asset cross-chain transaction contract, after the first transfer transaction is executed and identified on the first block chain, the second block chain calls the non-homogeneous asset cross-chain transaction contract of the first block chain based on the first transfer transaction to generate a second transaction instruction, and the second transaction instruction is used for casting or activating a second asset at the side of the second block chain; the second asset is a derived asset or a native asset of the first asset.
Further, the method of casting or activating a second asset at a second blockchain side includes:
casting the second asset directly based on the fixed attribute information of the first asset within the first transfer transaction when the first asset is an original production asset;
and when the first asset is a derived asset, judging whether a second block chain has a second asset in a logout state, if so, modifying the second state identifier to be effective, otherwise, casting the second asset based on the fixed attribute information of the first asset in the first transfer transaction.
The principle of the scheme provided by the embodiment is that the most difference between the non-homogeneous asset and the homogeneous asset is uniqueness, only certain users can hold the assets at the same time, and if the assets are transferred, corresponding owners need to be replaced; the transfer of non-homogeneous assets across the chain requires modification of the state of the non-homogeneous asset to logout or destruction on the initiating chain side, casting or activation on the target chain side. For example, in main chain destruction, in parallel chain casting, based on the same transfer transaction, the method is executed first on the main chain side, and first, whether the non-homogeneous asset meets the conditions is determined, for example, whether the non-homogeneous asset exists or not is judged, whether the time is effective or not, and the like, if the conditions are met, the transaction execution is successful, and the non-homogeneous asset is destroyed (the derived asset is on the initiating chain side); the parallel chain then synchronizes the same transaction, with the parallel chain side going on or casting (the target chain side being the derivative asset), and if activation or casting fails, e.g., the asset state cannot be modified or casting cannot be performed, the main chain side needs to restore the asset state to a valid state or to restore the destroyed asset.
