Background
Smart contracts are a computer protocol that propagates, validates, or executes contracts in an informative manner, allowing trusted transactions to be made without third parties, and which cannot be tracked while also being irreversible.
Because the blockchain has the characteristics of centralization, non-falsification and the like. Thus, smart contracts are typically implemented through blockchains. For example, smart contracts are implemented by ethernet.
The intelligent contract is executed with the corresponding currency. For example, when a smart contract is deployed on an ethernet, ethernet coin is required to drive the execution of the smart contract. When the user is not on the same chain with the intelligent contract, the user needs to exchange the currency of the user into the currency corresponding to the blockchain where the intelligent contract is located through a cross-chain technology, and then the user drives the intelligent contract to execute.
For example, the blockchain where the user is located is the a chain, the blockchain where the intelligent contract is located is the B chain, the user needs to exchange the a coin (the coin type corresponding to the a chain) into the C coin (the coin type corresponding to the C chain, at this time, the C chain is the intermediate node) through the gateway of the C chain, then the C coin is exchanged into the B coin through the gateway of the C chain, and finally the B coin is used to execute the intelligent contract.
However, the intermediate node is a centralized blockchain, the reliability of which is not guaranteed. In addition, two times of currency exchange, the exchange of the currency of the intermediate node into the corresponding currency of the intelligent contract always has delay, which leads to longer execution time of the intelligent contract, and thus, the transaction efficiency is low.

Example 1
An intelligent contract processing method according to a first embodiment of the present application is described below, and the method is applied to a node of a second blockchain, referring to fig. 1, and includes:
step S101, receiving an executing contract request sent by a node of a first blockchain, where the executing contract request includes target information of a contract to be executed and a first preset number of first digital assets, the first digital assets are legal assets of the first blockchain, and the contract to be executed is located on a second blockchain.
In step S101, the node of the first blockchain and the node of the second blockchain refer to terminal devices of contract participants. For example, the node of the first blockchain refers to the computer of contract party A and the node of the second blockchain refers to the computer of contract party B. The target information refers to related information of the contract to be executed, such as the name, number, execution parameter, and the like of the contract to be executed.
When the contract to be executed needs to be executed, the node of the first blockchain sends a contract executing request to the node of the second blockchain, and the node of the second blockchain receives the contract executing request.
Step S102, exchanging the first digital assets with the first preset number into second digital assets through a target gateway of the second blockchain, wherein the second digital assets are legal assets of the second blockchain.
In step S102, since the quorum asset of the first blockchain is the first digital asset, the second blockchain is to be executed. Therefore, when the node of the second blockchain receives the contract executing request, the node of the second blockchain needs to exchange the first digital assets with the first preset number into the second digital assets through the target gateway of the second blockchain, and then the second digital assets can be used to drive the execution of the contract to be executed.
And step S103, executing the contract to be executed according to the target information of the contract to be executed and the second digital asset, and obtaining an execution result of the contract to be executed.
In step S103, when the first digital assets with the first preset number are converted into the second digital assets, the node of the second blockchain executes the contract to be executed according to the target information of the contract to be executed and the second digital assets, so as to obtain an execution result of the contract to be executed.
In some possible implementations, the target information of the contract to be executed includes a target identifier of the contract to be executed and an execution parameter of the contract to be executed; correspondingly, executing the to-be-executed contract on the second blockchain according to the target information of the to-be-executed contract and the second digital asset to obtain an execution result of the to-be-executed contract, wherein the method comprises the following steps: searching a storage address corresponding to a target identifier of the contract to be executed in a second blockchain; sending the storage address, the execution parameters of the to-be-executed contract and the second digital asset to the virtual machine of the second blockchain to instruct the virtual machine of the second blockchain to search the contract state of the to-be-executed contract according to the storage address, and executing the to-be-executed contract according to the execution parameters of the to-be-executed contract, the contract state and the second digital asset to obtain an execution result of the to-be-executed contract; and receiving an execution result sent by the virtual machine of the second block chain.
In this implementation, the target information of the contract to be executed includes a target identifier of the contract to be executed and an execution parameter of the contract to be executed. After exchanging the first digital assets with the first preset number into the second digital assets, the nodes of the second blockchain search the storage addresses corresponding to the target identifiers of the contracts to be executed in the second blockchain. The node of the second blockchain then sends the storage address, the execution parameters of the contract to be executed, and the second digital asset to the virtual machine of the second blockchain. And searching the contract state of the contract to be executed by the virtual machine of the second blockchain according to the storage address, executing the contract to be executed according to the execution parameters, the contract state and the second digital asset of the contract to be executed to obtain an execution result of the contract to be executed, and sending the execution result to a node of the second blockchain. The node of the second blockchain thereby receives the execution result.
In some embodiments, the execution result includes a new contract state; after receiving the execution result sent by the virtual machine of the second blockchain, the method further comprises: the storage address of the new contract state in the execution result is stored in association with the target identification in the second blockchain.
In this embodiment, the execution result includes a new contract state after the contract to be executed is executed. After the virtual machine of the second blockchain obtains the execution result of the to-be-executed contract, storing a new contract state in the execution result, and sending the storage address of the new contract and the execution result to the node of the second blockchain. After the node of the second blockchain receives the request, the storage address of the new contract state in the execution result and the target identifier are stored in the second blockchain in a correlated mode. It should be appreciated that the execution contract request may also be stored in the second blockchain.
In other embodiments, prior to receiving the execution contract request sent by the node of the first blockchain, the method includes: receiving a deployment contract request, wherein the deployment contract request comprises byte codes of contracts to be executed and a second preset number of second digital assets; the byte code of the contract to be executed is deployed on a second blockchain and a second predetermined number of second digital assets are paid for.
In this embodiment, the deployment contract request includes the byte code of the contract to be executed and a second preset number of second digital assets. The node of the second blockchain first receives a deployment contract request. The byte code of the contract to be executed is then deployed on a second blockchain and a second predetermined number of second digital assets are paid for. It should be noted that, in order to facilitate maintenance of the contracts to be executed on the second blockchain, the synchronization method used by the nodes of the second blockchain in the process of deploying the bytecodes of the contracts to be executed on the second blockchain adopts a method of sequential synchronization and full synchronization, that is, adopts a method of sequential synchronization and full synchronization to synchronize the bytecodes of the contracts to be executed on the nodes of the second blockchain to other nodes of the second blockchain.
In some possible implementations, the method further includes: a target identification of the contract to be executed is generated. Accordingly, deploying the byte code of the contract to be executed on the second blockchain and paying for the second digital asset, including: sending the byte code of the contract to be executed and the second digital asset to the virtual machine of the second blockchain to instruct the virtual machine of the second blockchain to operate the byte code of the contract to be executed to obtain a contract state, and storing the contract state to obtain a storage address of the contract state; a storage address of the contract state is received and stored in a second blockchain in association with the target identification.
In this implementation, the virtual machine of the second blockchain runs the bytecode of the contract to be executed, and obtains the contract state. The contract state includes the participant variable of the contract to be executed, the function entry address table, the global variable table, the static variable table and the like. Then, the virtual machine of the second blockchain stores the contract state to obtain a storage address of the contract state, and sends the storage address of the contract state to the node of the second blockchain. After receiving the storage address of the contract state, the node of the second blockchain stores the storage address of the contract state in association with the target identifier in the second blockchain.
A specific application scenario of the present application is described below.
The first blockchain is a bit coin blockchain, the second blockchain is a Rainbow blockchain, the third blockchain is an Ethernet, the blockchain in which user A is located is the first blockchain to be executed on the Ethernet. Conventionally, when the user a wants to drive execution of a contract to be executed, it is necessary to exchange Cheng Ruibo coins for bitcoin, exchange the rapo coin for ethernet coin, and finally use the ethernet coin for driving execution of the contract to be executed. At this point, the second blockchain is the central node and there are two asset exchanges. In the present application, the to-be-executed contract is about on the second blockchain, and when the user a wants to drive the execution of the to-be-executed contract, the to-be-executed contract request is sent through the node of the first blockchain. And then the node of the second blockchain exchanges Cheng Ruibo coins for the bitcoin, and finally, the contract to be executed can be executed according to the request for the contract to be executed and the Rate coin.
In summary, the present application provides an intelligent contract processing method, first, a contract executing request sent by a node of a first blockchain is received, the contract executing request includes target information of a contract to be executed and a first preset number of first digital assets, the first digital assets are legal assets of the first blockchain, and the contract to be executed is located on a second blockchain. And then exchanging the first preset number of first digital assets into second digital assets through a target gateway of the second blockchain, wherein the second digital assets are legal assets of the second blockchain. And finally, executing the contract to be executed according to the target information of the contract to be executed and the second digital asset, and obtaining an execution result of the contract to be executed. Because the target gateway and the contracts to be executed are both on the second blockchain, only one time of asset exchange is needed, and no second time of asset exchange exists, the time for executing the contracts is reduced, and the transaction efficiency is improved. And at this time, the second blockchain is used as the blockchain where the intelligent contract is located and is not an intermediate node, so that the problem of centralization is solved.
In addition, the current contracts to be executed are all deployed on the third blockchain, and when a plurality of contract executing requests are received, the contracts to be executed can only be executed sequentially, so that the execution time is long and the efficiency is low. In the application, each contract to be executed can be deployed on each second blockchain, so that each contract to be executed can be executed simultaneously, the execution time of the contract to be executed is further reduced, and the transaction efficiency is improved.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present application.
