Detailed Description
The invention is further described with reference to the following figures and specific examples.
as shown in fig. 1, the present embodiment provides a method for asset circulation between various block chains, which is mainly used to solve the problem of asset exchange between different block chains, and the inventive main point of the present embodiment is to establish a micro asset distribution channel between different block chains. When cross-chain asset transaction is needed, the opponent asset is used as a new asset of the chain to be issued and the assets of the chain are frozen, so that the assets of other chains can be circulated in the original chain and in the new chain, the real cross-chain asset circulation is realized, and the total amount of the original assets can be ensured to be unchanged.
In this embodiment, the issued new asset is ensured to be valid by the asset approver, and the core role of the asset approver is to confirm the validity of the asset and manage the total amount of the asset. The asset approver comprises two core modules, an asset detection module and an asset accounting module. The asset detection module is used for verifying the availability and the authenticity of the assets according to local configuration; the asset accounting management module is used for managing all cross-chain assets of the chain and distributing the use condition.
in this embodiment, the problem of how two parties in a cross-chain agree that they have a portion of their assets on the other chain is solved by a transaction manager, which has the core role of helping the two chains to achieve a common asset cross-chain state. The transaction management comprises two core modules, an asset certificate management module and a transaction state synchronous management module. The asset certificate management module is used for confirming and keeping the cross-chain asset source; the transaction state membrane management module is used for cooperating with the two parties to jointly complete the issuance confirmation of the new asset.
in this embodiment, the destruction of the freezers ensures that the global volume of the asset can remain the same after the asset goes to another chain. The core effect of destroying the freezers is to keep the global total amount of the chain intact. The destroying freezer is provided with two core modules, namely an asset freezing module and an asset destroying module. The asset freezing module is used for freezing the assets of the chain when external new assets enter the chain, and ensuring that the total amount of the assets of the chain is maintained in an original state after the assets of the chain are removed; the asset destroying module is used for destroying the external assets when the external assets are transferred back, releasing the assets of the chain at the same time, and ensuring that the total amount of the assets of the chain is maintained as the original state when the external assets are transferred out.
