為了使本技術領域的人員更好地理解本發明中的技術方案，下面將結合本發明實施例中的圖式，對本發明實施例中的技術方案進行清楚、完整地描述，顯然，所描述的實施例僅僅是本發明一部分實施例，而不是全部的實施例。基於本發明中的實施例，本領域普通技術人員在沒有作出創造性勞動前提下所獲得的所有其他實施例，都應當屬本發明保護的範圍。
如前所述，目前的物聯網系統提供的是中心化的服務。這種方式下，資料的記錄和處理均在雲端平臺完成，因此安全性和客觀性並不可靠，無法適用於需要去壟斷、防篡改、防丟失的應用場景。
有鑒於此，本發明旨在提供一種可在物聯網中實現去中心化服務的技術方案。
圖1是本發明實施例基於區塊鏈的資料處理方法的流程圖。圖1所示的方法可以由下文相對應的裝置執行，包括：
步驟S102，區塊鏈平臺接收物聯網設備透過區塊鏈介面提交的包含指定資料的區塊鏈服務。
其中，指定資料可以包括物聯網設備產生的資料，比如：物聯網設備執行業務所產生的業務資料、日誌資料以及所述物聯網設備執行業務時對應的環境資料等。
具體地，物聯網設備若具有接入區塊鏈介面的能力，可將指定資料直接上傳至區塊鏈平臺。或者，物聯網設備也可以將指定資料發送至物聯網系統中的業務伺服器，由業務伺服器進一步透過區塊鏈介面上傳至區塊鏈平臺。
步驟S104，區塊鏈平臺基於區塊鏈服務，觸發預先部署在區塊鏈中的指定智慧合約，對區塊鏈服務中的指定資料進行處理。
其中，指定智慧合約可以由業務伺服器預先部署至區塊鏈中，包含有指定資料的處理邏輯。在本步驟中，區塊鏈平臺按照指定智慧合約指示的處理邏輯，對指定資料進行計算，得到對應的處理結果。
步驟S106，區塊鏈平臺調用物聯網設備的業務伺服器的應用程式可程式化介面，以將指定資料的處理結果反饋至業務伺服器。
應理解，業務伺服器在接收到指定資料的處理結果，再進一步基於處理結果執行相關業務的邏輯。
基於圖1所示的資料處理方法可以知道：本發明實施例的方案中，業務伺服器將指定資料的業務處理邏輯以智慧合約的方式部署在區塊鏈平臺中。物聯網設備將執行物聯網業務時產生的指定資料透過區塊鏈服務上傳至區塊鏈平臺，使區塊鏈平臺基於區塊鏈服務調用智慧合約，以對指定資料進行處理，並將處理結果反饋至業務處理器。由於指定資料的處理過程放在區塊鏈平臺執行，因此保證了處理結果的客觀性，從而實現了去中心化的服務。
下面對本發明實施例的方法進行示例性介紹。
本發明實施例的方法主要利用區塊鏈去中心化、防丟失、防篡改的分布式資料儲存技術，來負責記錄物聯網設備在執行物聯網業務時的指定資料，並在區塊鏈中部署具有該指定資料處理邏輯的指定智慧合約，物聯網設備需要將指定資料透過區塊鏈服務上傳至去中心化的區塊鏈平臺，由區塊鏈平臺調用指定智慧合約進行邏輯處理。
其中，流程包括：
步驟S201，物聯網中的業務伺服器接入區塊鏈平臺，並基於區塊鏈平臺向區塊鏈部署指定智慧合約。
應理解，指定智慧合約的具體處理邏輯是由物聯網業務實際需求所決定的，由於方式並不唯一，本發明實施例對此不作具體限定。
本步驟中，業務伺服器可以向區塊鏈部署與區塊鏈服務相關的指定智慧合約，使得區塊鏈在接收到區塊鏈服務後，觸發該指定智慧合約，以對區塊鏈服務中的資料進行處理。
步驟S202，物聯網設備連接區塊鏈介面，向區塊鏈平臺提交的包含指定資料的區塊鏈服務，或者，物聯網設備向業務伺服器提交包含指定資料的區塊鏈服務，由業務伺服器連接區塊鏈介面以區塊鏈平臺提交區塊鏈服務。
其中，指定資料可以是業務伺服器執行相關業務邏輯所需要的資料，可以但不限於包括以下至少一者：
物聯網設備執行業務所產生的業務資料。
物聯網設備執行業務所產生的日誌資料。
物聯網設備執行業務時對應的環境資料。
步驟S203，區塊鏈平臺向區塊鏈中的區塊鏈節點發起針對指定資料的多方共識。
應理解，區塊鏈多方共識的方式並不唯一，本發明實施例對此不作具體限定。
作為示例性介紹：上述區塊鏈具體可以是指聯盟鏈，聯盟鏈中指定有多個記帳節點。本步驟具體可以向聯盟鏈中的至少兩個記帳節點發起針對指定資料的多方共識。
步驟S204，在多方共識成功通過後，區塊鏈平臺在區塊鏈中添加記錄有指定資料的區塊。
顯然，通過多方共識的方式，可以對指定資料和/或指定資料的來源進行可靠性驗證，保證真實客觀的資料得到上鏈。指定資料一旦上鏈後，需要破壞超過半數以上的區塊鏈節點才能對其進行篡改，且破壞全部區塊鏈節點才將其從區塊鏈中徹底删除，理論上來講這些都是無法實現的，因此透過區塊鏈記錄物聯設備的指定資料，可以有效保障指定資料的安全性和客觀性。
步驟S205，區塊鏈平臺基於物聯網設備提交的區塊鏈服務，觸發預先部署在區塊鏈中的指定智慧合約，對指定資料進行處理。
應理解，處理流程根據實際的業務需求進行設置，由於方式並不唯一，在此不作贅述。
步驟S206，區塊鏈平臺調用物聯網設備的業務伺服器的應用程式可程式化介面，將指定資料的處理結果反饋至業務伺服器。
在上述基礎之上，區塊鏈平臺同時還可以將指定資料的處理結果反饋至物聯網設備。
步驟S207，業務伺服器根據接收到的指定資料的處理結果，執行相關的業務邏輯。
下面結合實際應用場景，對本發明實施例的方法進行詳細介紹。
在本應用場景中，業務伺服器為用戶提供電影票訂購服務。對於用戶來講，可以透過自己的個人設備(即物聯網設備)來向業務伺服器購買電影票。
對於同一場次同一座位的電影票來講，任何用戶都具有購買權利。為了保證這些用戶能夠公平購買，業務伺服器將電影票的購買處理邏輯以智慧合約的方式部署至區塊鏈，利用區塊鏈去中心化、防篡改的特點，保證智慧合約的客觀性。
假設用戶A希望購買16：00場6排14座的電影票，則可以透過個人設備向業務伺服器發起針對16：00場6排14座的電影票的購買請求(即區塊鏈服務)。業務伺服器將上述購買請求透過區塊鏈介面轉發至區塊鏈平臺，由區塊鏈平臺進行記錄。
之後，區塊鏈平臺調用預先為購票服務部署的智慧合約，對用戶A發起的購買請求進行處理。
假設智慧合約指示電影票先購先得的處理邏輯，如果該16：00場6排14座的電影票已經被其他用戶買走，則區塊鏈平臺產生拒絕用戶A購買請求的處理結果；如果該16：00場6排14座的電影票未被其他用戶買走，則區塊鏈平臺產生接受用戶A購買請求的處理結果。
或者，
假設智慧合約指示電影票隨機抽籤購買的處理邏輯，則區塊鏈平臺在滿足一定的時間條件後，對區塊鏈中記錄的所有發起該16：00場6排14座的電影票的購買請求的用戶進行抽籤。若用戶A中簽，則區塊鏈平臺產生接受用戶A購買請求的處理結果；若用戶A未中簽，則區塊鏈平臺產生拒絕用戶A購買請求的處理結果。
區塊鏈平臺在產生用戶A發起的購買請求的處理結果後，調用業務伺服器的應用程式可程式化介面，以將該處理結果發送至業務伺服器，由業務伺服器按照處理結果，決定是否向用戶A發起後續的購票流程。
以上是對本發明實施例的方法的介紹。應理解，在不脫離本文上述原理基礎之上，還可以進行適當的變化，這些變化也應視為本發明實施例的保護範圍。

在實際應用中，上述區塊鏈可以是聯盟鏈，聯盟鏈指定有多個記帳節點。上鏈模組在執行時，可以向所述聯盟鏈中的至少兩個記帳節點發起針對所述指定資料的多方共識。若超過半數記帳節點認可，則表示多方共識通過，上鏈模組再進一步將指定資料記錄至聯盟鏈中。
應理解，本發明實施例的裝置中的各個模組可以透過區塊鏈平臺執行對應的步驟。比如：上述獲取模組310能夠控制區塊鏈平臺接收物聯網設備透過區塊鏈介面提交的包含指定資料的區塊鏈服務。上述處理模組320，基於所述區塊鏈服務，控制區塊鏈平臺觸發預先部署在區塊鏈中的指定智慧合約，對所述區塊鏈服務中的指定資料進行處理指定智慧合約。上述反饋模組330，控制區塊鏈平臺調用物聯網設備的業務伺服器的應用程式可程式化介面，以將所述指定資料的處理結果反饋至業務伺服器。

Obviously, the described The embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
As mentioned earlier, the current Internet of Things system provides centralized services. In this way, the recording and processing of data are completed on the cloud platform, so the security and objectivity are not reliable, and it cannot be applied to application scenarios that require de-monopoly, tamper-proof, and loss-proof.
In view of this, the present invention aims to provide a technical solution that can realize decentralized services in the Internet of Things.
FIG. 1 is a flowchart of a data processing method based on blockchain according to an embodiment of the present invention. The method shown in Figure 1 can be executed by the following corresponding devices, including:
In step S102, the blockchain platform receives the blockchain service containing the specified data submitted by the Internet of Things device through the blockchain interface.
The specified data may include data generated by the Internet of Things device, such as business data generated by the Internet of Things device performing business, log data, and environmental data corresponding to the Internet of Things device performing business.
Specifically, if the IoT device has the ability to access the blockchain interface, it can directly upload the specified data to the blockchain platform. Alternatively, the IoT device can also send the specified data to the business server in the IoT system, and the business server further uploads it to the blockchain platform through the blockchain interface.
In step S104, based on the blockchain service, the blockchain platform triggers a designated smart contract pre-deployed in the blockchain to process the designated data in the blockchain service.
Among them, the designated smart contract can be pre-deployed into the blockchain by the business server, and contains the processing logic of the designated data. In this step, the blockchain platform calculates the specified data according to the processing logic indicated by the specified smart contract to obtain the corresponding processing result.
In step S106, the blockchain platform calls the programmable interface of the business server of the Internet of Things device to feed back the processing result of the specified data to the business server.
It should be understood that, after receiving the processing result of the specified data, the business server further executes the logic of the related business based on the processing result.
Based on the data processing method shown in FIG. 1, it can be known that in the solution of the embodiment of the present invention, the business server deploys the business processing logic of the specified data on the blockchain platform in the form of a smart contract. The Internet of Things device uploads the designated data generated during the execution of the Internet of Things business to the blockchain platform through the blockchain service, so that the blockchain platform calls the smart contract based on the blockchain service to process the designated data and process the results Feedback to the business processor. Since the processing of the specified data is executed on the blockchain platform, the objectivity of the processing results is guaranteed, thereby realizing decentralized services.
The method of the embodiment of the present invention will be exemplarily introduced below.
The method of the embodiment of the present invention mainly uses the distributed data storage technology of blockchain decentralization, loss-proof and tamper-proof, to be responsible for recording the specified data of the Internet of Things equipment when performing the Internet of Things business, and deploy it in the blockchain With the designated smart contract with the designated data processing logic, the IoT device needs to upload the designated data to the decentralized blockchain platform through the blockchain service, and the designated smart contract is called by the blockchain platform for logical processing.
Among them, the process includes:
In step S201, the business server in the Internet of Things accesses the blockchain platform, and deploys a designated smart contract to the blockchain based on the blockchain platform.
It should be understood that the specific processing logic of the designated smart contract is determined by the actual requirements of the Internet of Things business. Since the method is not unique, the embodiment of the present invention does not specifically limit this.
In this step, the business server can deploy a designated smart contract related to the blockchain service to the blockchain, so that after the blockchain receives the blockchain service, the designated smart contract is triggered to provide services to the blockchain. Data to be processed.
In step S202, the IoT device connects to the blockchain interface and submits the blockchain service containing the specified data to the blockchain platform, or the IoT device submits the blockchain service containing the specified data to the business server, and the business server The device connects to the blockchain interface to submit blockchain services on the blockchain platform.
Wherein, the specified data may be data required by the business server to execute related business logic, and may but not be limited to include at least one of the following:
The business data generated by the Internet of Things equipment to execute the business.
The log data generated by the Internet of Things equipment to execute the business.
Corresponding environmental data when the Internet of Things device performs business.
In step S203, the blockchain platform initiates a multi-party consensus on the specified data to the blockchain nodes in the blockchain.
It should be understood that the multi-party consensus on the blockchain is not unique, and the embodiment of the present invention does not specifically limit this.
As an exemplary introduction: the above-mentioned blockchain may specifically refer to a consortium chain, and multiple accounting nodes are designated in the consortium chain. This step can specifically initiate a multi-party consensus on the specified data to at least two accounting nodes in the alliance chain.
In step S204, after the multi-party consensus is successfully passed, the blockchain platform adds a block recording the specified data to the blockchain.
Obviously, through multi-party consensus, the reliability of the designated data and/or the source of the designated data can be verified to ensure that the true and objective data is uploaded to the chain. Once the specified information is on the chain, more than half of the blockchain nodes need to be destroyed before it can be tampered with, and all the blockchain nodes are destroyed before they are completely deleted from the blockchain. In theory, these are impossible to achieve Therefore, recording the specified data of the IoT device through the blockchain can effectively protect the security and objectivity of the specified data.
In step S205, the blockchain platform triggers a designated smart contract pre-deployed in the blockchain based on the blockchain service submitted by the Internet of Things device to process the designated data.
It should be understood that the processing flow is set according to actual business requirements, and since the method is not unique, it will not be repeated here.
In step S206, the blockchain platform calls the programmable interface of the application program of the business server of the Internet of Things device, and feeds back the processing result of the specified data to the business server.
On the basis of the above, the blockchain platform can also feed back the processing results of the specified data to the Internet of Things devices.
In step S207, the business server executes the relevant business logic according to the processing result of the received designated data.
The method of the embodiment of the present invention will be described in detail below in combination with actual application scenarios.
In this application scenario, the business server provides users with movie ticket ordering services. For users, they can purchase movie tickets from the business server through their personal devices (ie, IoT devices).
For movie tickets with the same seat for the same show, any user has the right to purchase. In order to ensure that these users can purchase fairly, the business server deploys the movie ticket purchase processing logic to the blockchain in the form of a smart contract, and uses the decentralized and tamper-proof features of the blockchain to ensure the objectivity of the smart contract.
Assuming that user A wants to purchase 16:00 movie tickets with 6 rows and 14 seats, he can initiate a purchase request for 16:00 movie tickets with 6 rows and 14 seats to the service server through his personal device (i.e. blockchain service). The business server forwards the above-mentioned purchase request to the blockchain platform through the blockchain interface, and the blockchain platform records it.
After that, the blockchain platform invokes the smart contract deployed in advance for the ticket purchase service to process the purchase request initiated by user A.
Assuming that the smart contract instructs the processing logic of movie tickets first-served, if the 16:00 movie tickets with 6 rows and 14 seats have been bought by other users, the blockchain platform will generate a processing result that rejects user A's purchase request; if The 16:00 movie tickets with 6 rows and 14 seats are not bought by other users, and the blockchain platform generates a processing result of accepting user A's purchase request.
or,
Assuming that the smart contract instructs the processing logic for the random lottery purchase of movie tickets, the blockchain platform will, after a certain time condition is met, will initiate the purchase request of the 16:00 movie tickets with 6 rows and 14 seats recorded in the blockchain. Of users conduct a lottery. If user A wins the lottery, the blockchain platform generates a processing result of accepting user A's purchase request; if user A fails to win the lottery, the blockchain platform generates a processing result that rejects the purchase request of user A.
After the blockchain platform generates the processing result of the purchase request initiated by user A, it calls the application programmable interface of the business server to send the processing result to the business server, and the business server decides whether or not according to the processing result Initiate the subsequent ticket purchase process to user A.
The above is an introduction to the method of the embodiment of the present invention. It should be understood that appropriate changes can be made without departing from the foregoing principles herein, and these changes should also be regarded as the protection scope of the embodiments of the present invention.
Corresponding to the foregoing data processing method, as shown in FIG. 3, an embodiment of the present invention also provides a blockchain-based data processing device 300, including:
The receiving module 310 receives the blockchain service containing specified data submitted by the Internet of Things device through the blockchain interface.
The specified data may include data generated by the Internet of Things device, such as business data generated by the Internet of Things device performing business, log data, and environmental data corresponding to the Internet of Things device performing business.
Optionally, in this step, if the IoT device has the ability to access the blockchain interface, the designated data can be directly uploaded to the blockchain platform. Alternatively, the IoT device can also send designated data to the business server, and after the business server accesses the blockchain interface, the blockchain service is further uploaded to the blockchain platform.
The processing module 320, based on the blockchain service, triggers a designated smart contract pre-deployed in the blockchain, and processes the designated smart contract on the designated data in the blockchain service.
Among them, the designated smart contract can be pre-deployed into the blockchain by the business server, and contains the processing logic of the designated data. In this step, the blockchain platform calculates the specified data according to the processing logic indicated by the specified smart contract to obtain the corresponding processing result.
