Technical Field

Background
Smart contracts are a computerized protocol for propagating, validating or executing contracts in an informational manner that allows trusted transactions to be conducted without a third party and that are not traceable and at the same time are irreversible.
The block chain has the characteristics of centralization, non-tampering and the like. Thus, intelligent contracts are typically implemented through blockchains. For example, intelligent contracts are implemented through etherhouses.
Corresponding currency is needed when the intelligent contract is executed. For example, when smart contracts are deployed on an ethernet house, the ethernet house currency is required to drive the execution of the smart contracts. When the user is not in the same chain with the intelligent contract, the user needs to exchange the currency of the user into the currency corresponding to the block chain where the intelligent contract is located through a chain crossing technology, and then the user drives the execution of the intelligent contract.
For example, the block chain where the user is located is an a chain, and the block chain where the intelligent contract is located is a B chain, the user needs to exchange the a coin (the currency type corresponding to the a chain) into the C coin (the currency type corresponding to the C chain, at this time, the C chain is an 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, and the credibility thereof is not guaranteed. In addition, the exchange of currency is performed twice, and the exchange of the currency of the intermediate node into the currency corresponding to the intelligent contract always has delay, so that the time for executing the intelligent contract is long, and the transaction efficiency is low.

In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Example one
In the following, an intelligent contract processing method provided in an embodiment of the present application is described, where the method is applied to a node of a second blockchain, and please refer to fig. 1, where the method includes:
step S101, receiving a contract execution request sent by a node of a first block chain, wherein the contract execution request comprises 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 block chain, and the contract to be executed is located on a second block chain.
In step S101, the node of the first blockchain and the node of the second blockchain refer to the terminal devices of the contracting parties. For example, a node of the first blockchain refers to a computer of the contracting party a, and a node of the second blockchain refers to a computer of the contracting party B. The target information refers to relevant information of the contract to be executed, such as the name, number and execution parameters of the contract to be executed.
When a contract to be executed needs to be executed, a node of the first blockchain sends an execution contract request to a node of the second blockchain, and the node of the second blockchain receives the execution contract request.
And step S102, converting the first digital assets of the first preset quantity into second digital assets through the target gateways of the second block chain, wherein the second digital assets are legal assets of the second block chain.
In step S102, since the statutory asset of the first blockchain is the first digital asset, the close to be executed is on the second blockchain. Therefore, when a node of the second blockchain receives a contract execution request, the node of the second blockchain needs to convert the first digital assets of the first preset quantity into the second digital assets through the target gateway of the second blockchain, and then the second digital assets can be used for driving 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 to obtain an execution result of the contract to be executed.
In step S103, when the first digital assets of the first preset number are exchanged into the second digital assets, the nodes of the second block chain execute 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 the execution result of the contract to be executed.
In some possible implementation manners, the target information of the contract to be executed comprises a target identification of the contract to be executed and an execution parameter of the contract to be executed; correspondingly, executing the contract to be executed on the second block chain according to the target information of the contract to be executed and the second digital asset to obtain an execution result of the contract to be executed, wherein the execution result comprises: searching a storage address corresponding to a target identifier of a contract to be executed in a second block chain; sending the storage address, the execution parameters of the contract to be executed and the second digital assets to a virtual machine of a second block chain to indicate the virtual machine of the second block chain to search for the contract state of the contract to be executed according to the storage address, and executing the contract to be executed according to the execution parameters of the contract to be executed, the contract state and the second digital assets to obtain the execution result of the contract to be executed; and receiving an execution result sent by the virtual machine of the second blockchain.
In this implementation manner, 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. And after the first digital assets with the first preset quantity are converted into the second digital assets by the nodes of the second block chain, searching a storage address corresponding to a target identifier of a contract to be executed in the second block chain. And then the node of the second block chain sends the storage address, the execution parameter of the contract to be executed and the second digital asset to the virtual machine of the second block chain. And the virtual machine of the second block chain searches the contract state of the contract to be executed according to the storage address, executes the contract to be executed according to the execution parameter of the contract to be executed, the contract state and the second digital asset to obtain the execution result of the contract to be executed, and sends the execution result to the node of the second block chain. The nodes of the second blockchain thus receive the execution results.
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 following steps: and storing the storage address of the new contract state in the execution result and the target identification in association in the second block chain.
In this embodiment, the execution result includes the new contract status after the contract to be executed is executed. And after obtaining the execution result of the contract to be executed, the virtual machine of the second block chain stores the new contract state in the execution result, and the storage address of the new contract and the execution result are sent to the node of the second block chain. And after the node of the second block chain receives the result, the storage address of the new contract state in the execution result and the target identification are stored in the second block chain in an associated manner. It should be understood that the execution contract request may also be stored in the second blockchain.
In some embodiments, before receiving the execution contract request sent by the node of the first blockchain, the method further includes: receiving a contract deployment request, wherein the contract deployment request comprises byte codes of a contract to be executed and a second preset number of second digital assets; the bytecode for the contract to be executed is deployed on a second blockchain, and a second preset amount of second digital assets is paid out.
In this embodiment, the deployment contract request includes bytecode of the contract to be executed and a second preset number of second digital assets. The nodes of the second blockchain first receive a deployment contract request. The bytecode of the contract to be executed is then deployed on a second blockchain and a second preset amount of second digital assets is paid for. It should be noted that, in order to facilitate maintenance of the contract to be executed on the second blockchain, the synchronization method used by the nodes of the second blockchain in the process of deploying the bytecode of the contract to be executed on the second blockchain is a sequential synchronization and full synchronization method, that is, the bytecode of the contract to be executed on the nodes of the second blockchain is synchronized to other nodes of the second blockchain by using the sequential synchronization and full synchronization method.
In some possible implementations, the method further includes: and generating a target identification of the contract to be executed. Accordingly, deploying bytecode of the contract to be executed on the second blockchain and paying for the second digital asset includes: sending the byte codes of the contracts to be executed and the second digital assets to the virtual machine of the second block chain to indicate the virtual machine of the second block chain to run the byte codes of the contracts to be executed to obtain contract states, and storing the contract states to obtain storage addresses of the contract states; a memory address of the contract state is received and stored in the second blockchain in association with the target identification.
In this implementation, the virtual machine of the second block chain runs the bytecode of the contract to be executed, and the contract state is obtained. The contract state comprises participant variables of the contract to be executed, a function entry address table, a global variable table, a static variable table and the like. And then, the virtual machine of the second block chain 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 block chain. And after receiving the storage address of the contract state, the node of the second block chain stores the storage address of the contract state and the target identification in the second block chain in an associated manner.
A specific application scenario of the present application is described below.
The first block chain is a bit coin block chain, the second block chain is a Raymond coin block chain, the third block chain is an Ethernet workshop, a contract to be executed is on the Ethernet workshop, and the block chain where the user A is located is the first block chain. Conventionally, when the user a wants to drive the execution of a contract to be executed, it is necessary to exchange the bitcoin for the rem coin, the rem coin for the ethernet coin, and finally, the ethernet coin is used to drive the execution of the contract to be executed. At this point, the second blockchain is the central node and there are two asset redemptions. In the present application, the contract to be executed is bound to the second block chain, and when the user a wants to drive the execution of the contract to be executed, a contract request to be executed is sent through the node of the first block chain. And then the node of the second block chain exchanges the bit coins into the Rebo coins, and finally the contract to be executed can be executed according to the contract to be executed request and the Rebo coins.
In summary, the present application provides an intelligent contract processing method, which includes receiving a contract execution request sent by a node of a first block chain, where the contract execution 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 block chain, and the contract to be executed is located on a second block chain. And then the first digital assets with the first preset quantity are converted into second digital assets through the target gateways of the second block chain, and the second digital assets are legal assets of the second block chain. And finally, executing the contract to be executed according to the target information of the contract to be executed and the second digital asset to obtain an execution result of the contract to be executed. Because the target gateway and the contract to be executed are both arranged on the second block chain, only one-time asset exchange is needed, and the second-time asset exchange does not exist, the contract execution time is reduced, and the transaction efficiency is improved. And, at this moment, the second blockchain is the blockchain that the intelligent contract belongs to, and is not the intermediate node, thereby the problem of centralization has been solved.
Moreover, the current contracts to be executed are all deployed on the third block chain, and when a plurality of contract execution requests are received, the contracts to be executed can only be executed in sequence, so that the execution time is long, and the efficiency is low. In the application, each second block chain for deploying each contract to be executed can be linked, 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 numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
