Description

Transaction system and method based on intelligent contract wallet Technical Field The invention relates to the technical field of digital currency, in particular to a transaction system and method based on an intelligent contract wallet. Background For transactions in a smart contract wallet, there is typically both a change in contract data state and a change in the amount in the smart contract wallet when executing the smart contract. However, the present transaction related to the smart contract wallet is generally implemented through multi-system interaction, that is, the execution of the smart contract and the payment receipt and payment of the smart contract wallet are implemented through different systems, which may cause failure of the smart contract wallet to receive and pay after the contract data is submitted, and the smart contract cannot be reversely operated, so that the system for executing the smart contract is inconsistent with the data of the payment receipt and payment system of the smart contract wallet. Disclosure of Invention In view of this, an embodiment of the present invention provides a transaction system and method based on an intelligent contract wallet, in which a contract calling system triggers a contract execution system according to a contract calling request, and the contract execution system executes an intelligent contract corresponding to a target intelligent contract wallet and caches contract data without directly submitting the contract data. The contract execution system submits the contract data after the coin counting core system calls the target intelligent contract wallet to succeed in transaction, and clears the contract data if the target intelligent contract wallet fails in transaction. Therefore, the contract execution system does not submit corresponding contract data after executing the intelligent contract, and submits the contract data after determining that the transaction of the coin counting core system is successful, so that the problem of inconsistent data caused by failure of the target intelligent contract wallet after submitting the contract data is avoided, and the data consistency of the intelligent contract transaction system is realized. To achieve the above object, according to one aspect of an embodiment of the present invention, there is provided a smart contract wallet-based transaction system. The transaction system based on the intelligent contract wallet comprises a contract calling system, a coin counting core system and a contract executing system, wherein, The contract calling system is configured to acquire a contract calling request and trigger the contract executing system according to the contract calling request, wherein the contract calling request indicates a target intelligent contract wallet to be transacted; the contract execution system is configured to execute an intelligent contract corresponding to the target intelligent contract wallet, buffer contract data, generate a transaction instruction according to the contract data, send the transaction instruction to the coin counting core system, clear the contract data in response to the transaction result of the coin counting core system being a transaction failure, and submit the contract data in response to the transaction result being a transaction success; the coin counting core system is used for calling the target intelligent contract wallet to conduct transaction according to the transaction instruction and returning the transaction result to the contract execution system. Optionally, the target smart contract wallet is a payment wallet; the contract calling system is also configured to acquire the collection result of the target collection wallet and call the contract executing system according to the collection result; And the contract execution system is configured to execute the intelligent contract according to the collection result and set a corresponding transfer state according to the collection result. Optionally, the contract invoking system is configured to transmit the collection result as an entry of the smart contract to the contract execution system, such that the contract execution system executes the smart contract according to the collection result. Alternatively, in the event that the target wallet fails to collect, The contract execution system is configured to execute an intelligent contract according to the result of collection failure to obtain and buffer callback contract data, and send a collection instruction to the coin counting core system; the coin counting core system is configured to call the target intelligent contract wallet to collect according to the collection instruction and return the collection result to the contract execution system. Alternatively, in the case where the target wallet is a smart contract wallet, The target intelligent contract wallet and the target money receiving wallet respectively correspond to different co
