Specifically, the embodiment is based on that a host which has a domain name or an address on the internet and provides a certain network service has a space for storing files, and a server is used as a carrier, so that a user can access and search files through a browser and the like, and can upload and receive website data in a remote File Transfer Protocol (FTP) manner.
The user operates the subsystem 1 to perform order requirement matching, create or call intelligent contracts based on the blockchain and view blockchain information in a visual interface by using a Web service based on the blockchain. The user can join and use only by registering on the manufacturing service transaction system enabled by the intelligent contract provided by the embodiment; in the implementation, the users specifically refer to buyers, sellers and logistics companies; the user operation subsystem 1 in this embodiment includes a specific operation interface or an application client for the buyer, the manufacturer, and the logistics company, respectively.
As a preferred embodiment, the data subsystem 3 includes a regular data module 31 and a block chain data module 32, wherein: the conventional data module 31 is used for storing buyer information and manufacturer information, and the block chain data module 32 is used for carrying transaction details in the transaction record and the completion of orders and logistics.
Through the arrangement, the conventional data related to data processing operations such as information matching and the like are separated from the blockchain information related to transaction security, and the efficiency of data processing and the security of the data are effectively considered.
Specifically, in an alternative embodiment, the conventional data module 31 may be implemented by a common database including mysql; the blockchain data module 32 may be implemented using an existing blockchain platform, such as a super book or an ethernet house, and use the consensus mechanism and management function provided by the blockchain platform.

Preferably, the intelligent contract defines the commodity attribute, quantity, price, delivery period, transaction condition, delivery verification standard, calculation mode, payment period, order completion judgment condition and event response processing mode corresponding to the buyer, the manufacturer and the logistics company in the form of codes during the transaction.
Specifically, referring to fig. 4 and 5, the implementation code of the intelligent contract may be regarded as a decentralized and absolutely executed computer program running on a block chain, and If-then and What-If statements may be used to preset trigger scenarios corresponding to various events and to respond to callbacks. In the process of creating the intelligent contract, the system can enable the specific content of the intelligent contract to be viewed by the user in a character form, and the user can view the source code to ensure the authenticity of the contract. When the intelligent contract is created, the user only needs to input parameters of events needing to be set in the transaction to complete the intelligent contract deployment. Meanwhile, the user can add other corresponding affairs and response rules on the premise of mutual negotiation.
Referring to fig. 6, the smart contract preferably includes a first response transaction and a second response transaction; the first response transaction is used for judging the order completion condition sent by the buyer and the manufacturer, and returning an order judgment result to the second response transaction; and the second response transaction is automatically executed according to the specified time and is used for carrying out transaction success processing or transaction exception processing according to the order judgment result.
Specifically, the determination of the first response transaction regarding the order completion is divided into two scenarios: firstly, after the manufacturer finishes the order task, when the manufacturer is delivered with the logistics company, the manufacturer and the logistics company need to determine the product according to contract content and order content, the manufacturer sends the information required by the intelligent contract to the logistics company in the platform, after the logistics company determines, the information is automatically transmitted into the intelligent contract execution environment (if the information cannot be input, the transaction is finished); secondly, when the logistics company sends the product to the buyer, when the goods receiving confirmation is carried out, the buyer needs to confirm the order information of the received product and the logistics company, the information required by the intelligent contract to be input is sent to the logistics company, the information is automatically transmitted into the intelligent contract execution environment after the logistics company confirms (if the information cannot be input without confirmation), and the transaction is completed. Therefore, the input correctness of the intelligent contract information is ensured.
Since the entry of information is limited by the parties contracting, if two parties diverge in the entered information in a node, the transaction may never trigger a response. Through the setting of the second response transaction, the transaction can be automatically triggered when the time specified by each transaction party is reached, the function in the second response transaction can judge whether the previous transaction is executed, and if the previous transaction is executed, the transaction is successfully processed; if the transaction is not executed, transaction exception processing is carried out on the transaction, agreed penalties are carried out on all parties in the transaction (the purpose is to enable any party to input information incorrectly is to enable all people to be unable to obtain benefits and suffer losses, the amount of the penalties is larger than the stipulated penalty compensation), and beneficiary parties are temporarily a platform. Meanwhile, the transaction problem is returned to reality according to the actual situation, all parties in the transaction need to contact police and the platform to solve according to the intelligent contract content and the actual situation, the contract code is stored in the block chain, the contract content cannot be tampered, so that the problem processing according to the credible contract content is much easier than general transaction disputes, the platform redistributes the obtained punishment amount according to the processing result after the event, the transaction efficiency is greatly improved, and the solving cost of various problems is reduced.
The invention also comprises the following:
a storage medium having stored thereon a computer program and further having stored thereon a smart contract enabled manufacturing services transaction system as described above.
A computer apparatus comprising a storage medium, a processor, and a computer program stored in the storage medium and executable by the processor, and the smart contract enabled manufacturing services trading system described above.
