step S10, in response to the detected cross-chain interaction request, acquiring an information interacting party corresponding to the cross-chain interaction request, wherein the information interacting party comprises an information providing party and an information requiring party, and the information providing party and the information requiring party are nodes located on different chains;
in this embodiment, the cross-chain interaction method of the blockchain is applied to information interaction between different blockchain systems or between different chains in the same blockchain system. It can be understood that, in the blockchain, when a transaction request is generated, a corresponding transaction process needs to be triggered based on the transaction request, in the transaction process, transaction data needs to be exchanged between nodes located in the blockchain, and the nodes where data exchange exists may be on the same chain or different chains, which is not specifically limited herein. In the following, the nodes performing information interaction are located on different chains as an example.
When a cross-chain interaction request is detected, in order to respond to the detected cross-chain interaction request, an information interaction party corresponding to the cross-chain interaction request is obtained, wherein the cross-chain interaction request can be a transaction request or a data interaction request generated based on the transaction request of a user.

In this embodiment, the block chain is hierarchically divided according to main chains in the block chain, and asset data interaction between heterogeneous chains is realized based on a hierarchical partition mode, where each main chain is a parent domain, a side chain extended from the main chain is a sub-domain of the parent domain where the main chain is located, and when information interaction is performed on nodes located in different sub-domains, it is necessary to trace up to a common node layer by layer to determine a common parent domain of an information machine interaction party, and form a domain set, and then perform interaction based on an information interaction rule of the parent domain, and record all information related to the information interaction in all domains included in the domain set. It should be noted that, in the blockchain system, the bottom main chain is a parent domain of all the side chains extending from the bottom main chain, and the side chains extending from the main chain can also be used as parent domains of other side chains, that is, the same side chain on the bottom main chain can be used as a child domain of the main chain and a parent domain of other side chains at the same time.
It is known that, according to the network range of the blockchain, the chains in the blockchain can be divided into a public chain, a private chain and a federation chain, the main chain is generally an independent blockchain network, and the public chain is generally a blockchain that anyone can read, can send a transaction, can effectively confirm the transaction, and can participate in the consensus process. In this embodiment, the main chain is generally a public chain, the nodes on the main chain are public nodes, and the side chains on the main chain may be public chains or private chains or alliance chains.

Further, in an embodiment, the step of obtaining the intelligent contract corresponding to the public node includes:
step S301, based on the public node, utilizing a preset contract engine to perform indexing, and determining contract information corresponding to the public node, wherein the contract information comprises a contract address and a contract name;
step S302, obtaining an intelligent contract corresponding to the public node according to the contract address and the contract name in the contract information.
In this embodiment, a contract engine is preset in the block chain, and when an intelligent contract corresponding to a public node of the information demander and the information provider is obtained, the preset contract engine is used for indexing based on the public node to determine contract information corresponding to the public node, where the contract information includes a contract address and a contract name, and further includes contract parameters. And determining and acquiring the intelligent contract corresponding to the public node according to the contract address and the contract name in the contract information.
Further, in an embodiment, the refining of step S30 further includes:
step S303, calling an intelligent contract corresponding to the public node according to contract calling parameters in the contract information to determine a target interactive address;
and step S304, performing information interaction at the target interaction address according to the interaction rule corresponding to the intelligent contract.

By calling the intelligent contract, the interaction of the information demander and the information provider is actually the interaction between the intelligent contracts deployed on the public chain of the chain where the information demander and the information provider are located, and based on the intelligent contracts respectively deployed on the public chain at the bottom layer, the information interaction between different block chain systems and between different chains in the same block chain system can be realized, and the chain-crossing interaction of the block chains is realized.

The intelligent contracts are respectively deployed based on different low-level public chains, and the intelligent contracts of the public nodes are suitable for the lower-level nodes of the public nodes through the public nodes of the information interaction parties, so that the interaction is carried out based on the interaction rules of the public nodes corresponding to the intelligent contracts, the information interaction between isomorphic chains or heterogeneous chains can be realized, and the purpose of cross-chain information interaction is achieved.
Further, on the basis of the above embodiments of the present invention, a second embodiment of the block chain cross-chain interaction method of the present invention is provided.
This embodiment is a step of step S20 refinement in the first embodiment, and in this embodiment, the refinement of step S20 includes:
step S201, tracing the upper nodes of the chain where the information provider and the information demander are located in the same level layer by layer;
in this embodiment, when tracing up to the public node of the chain where the information provider and the information demander are located layer by layer, specifically, tracing up to the upper node of the chain where the information provider and the information demander are located in the same hierarchy layer by layer. In the implementation, the blockchain is hierarchically divided according to the main chain of the chain where the information provider and the information demander are located, and upper-layer nodes are traced layer by layer until the common nodes of the chain where the information provider and the information demander are located on the same level are determined, so that the common parent domain of the sub-domains where the information provider and the information demander are located is determined.
Step S202, detecting the node type of the upper node, wherein the node type comprises all nodes;
further, when the common nodes of the chain where the information provider and the information demander are located are traced, specifically, upper-layer nodes are traced on the chain where the information provider and the information demander are located layer by layer, and then the node types of the upper-layer nodes are detected, wherein the node types include full nodes and light nodes. In the block chain, the more nodes, the more widely distributed the nodes, the more decentralized the block chain network, and the safer and more stable the operation of the block chain network. In a decentralized blockchain network, the node type may be determined according to the type of the chain in which the node is located, for example, a node on a public chain is generally a full node, the full node possesses all transaction data of the blockchain whole network, a node on a private chain is generally a light node, and the light node possesses only transaction data related to itself.
Step S203, when the node type of the upper node is a global node, using the upper node as a public node of the information provider and the information demander.

Further, the public node is a full node, which contains global information of the block chain, and based on this, the step of interacting according to the interaction rule corresponding to the intelligent contract corresponding to the public node may further include:

step A2, when the verification is passed, the cross-chain interaction request is forwarded to the information provider, so that the information provider can respond to the cross-chain interaction request according to the interaction rule corresponding to the intelligent contract, and perform information interaction with the information demander.
After calling an intelligent contract and determining a target interaction address, when interaction is performed according to interaction rules corresponding to the intelligent contract, firstly, a detected cross-link request is verified according to global information in a public node, and when the verification is passed, the cross-link request is forwarded to an information provider so that the information provider can respond to the cross-link request according to the interaction rules corresponding to the intelligent contract, and information interaction is performed with an information demand party.
Further, in this embodiment, a predictive engine is also preset in the blockchain, and the predictive engine may be configured to listen to the cross-chain request event log, and forward and verify the interaction data of the information interaction party. The method comprises the steps that a prediction machine creates a monitoring node in a block chain and is used for monitoring whether a cross-chain request event exists or not, when a cross-chain interaction request is detected, after a public node verifies the cross-chain interaction request, the cross-chain protection request is transmitted to an information provider, the information provider responds to the cross-chain interaction request, and a processing result of the information provider is returned to the public node for recording. The prediction machine also verifies the data returned by the information provider, and finally forwards the verification result and the returned data to the information demand side together to complete the cross-chain interaction event.
