這裡將詳細地對示例性實施例進行說明，其示例表示在圖式中。下面的描述涉及圖式時，除非另有表示，不同圖式中的相同數字表示相同或相似的要素。以下示例性實施例中所描述的實施方式並不代表與本說明書一個或多個實施例相一致的所有實施方式。相反地，它們僅是與如所附申請專利範圍中所詳述的、本說明書一個或多個實施例的一些態樣相一致的裝置和方法的例子。
需要說明的是：在其他實施例中並不一定按照本說明書示出和描述的順序來執行對應方法的步驟。在一些其他實施例中，其方法所包括的步驟可以比本說明書所描述的更多或更少。此外，本說明書中所描述的單個步驟，在其他實施例中可能被分解為多個步驟進行描述；而本說明書中所描述的多個步驟，在其他實施例中也可能被合併為單個步驟進行描述。
隨著網際網路科技的發展，基於網路的服務模式不斷地推陳出新。對於彼此不熟識的服務者和被服務者，由於彼此間的陌生可能帶來很多安全隱患，這種安全隱患尤其是在遠端服務或上門服務等服務模式中尤為凸顯。
基於以上提出的技術現狀和問題，圖1是本說明書所提供的一實施例所示的基於區塊鏈的資料處理方法，所述區塊鏈包括服務平台節點設備。
本實施例所述的服務平台可包括受理使用者某類型的服務需求或服務提供，而進行服務撮合或服務分配等業務的平台性質服務機構，例如上門服務(如家政類服務、維修類服務、家教類服務)業務撮合平台、遠端服務(如遠端教學)業務撮合平台等等，在本說明書中不作限定。
本實施例所述的區塊鏈，具體可指一個各節點透過共識機制達成的、具有分散式資料儲存結構的P2P網路系統，該區塊鏈內的資料分佈在時間上相連的一個個“區塊(block)”之內，後一區塊包含前一區塊的資料摘要，且根據具體的共識機制(如POW、POS、DPOS或PBFT等)的不同，達成全部或部分節點的資料全備份。本領域的技術人員熟知，由於區塊鏈系統在對應共識機制下運行，已收錄至區塊鏈資料庫內的資料很難被任意的節點篡改，例如採用Pow共識的區塊鏈，至少需要全網51%算力的攻擊才有可能篡改已有資料，因此區塊鏈系統有著其他中心化資料庫系統所無法比擬的保證資料安全、防攻擊篡改的特性。由此可知，在本說明書所提供的實施例中，被收錄至區塊鏈的分散式資料庫中的資料不會被攻擊或篡改，從而保證了上述服務平台節點設備向上述區塊鏈存證的資料資訊的真實可靠性。
本實施例所述的服務平台節點設備，可透過遵循對應節點協定、運行節點協定程式的安裝來加入該區塊鏈，作為該區塊鏈的節點。本領域的技術人員通常將具有區塊鏈分散式資料庫的資料全備份的節點設備稱為全節點，將具有區塊鏈分散式資料庫的部分備份資料(如僅有區塊頭的資料)的節點設備稱為輕節點或用戶端等；在本實施例中所述的服務平台節點設備可包括上述的全節點、輕節點或用戶端，只要直接或間接連入上述區塊鏈、且可發送或獲取區塊鏈的分散式資料庫的資料的任何設備均可稱為本實施例所述的節點設備。

服務提供方可在註冊成為上述服務平台的服務提供人員時，將上述身分識別資訊錄入到服務平台節點設備中，並由上述服務平台節點設備將上述身分識別資訊存證到區塊鏈的分散式資料庫中。值得注意的是，將上述身分識別資訊存證於區塊鏈的分散式資料庫中的具體方式可以有多種，除了將上述身分識別資訊的原文備份到區塊鏈的分散式資料庫中，由各節點設備共同備份維護；由於上述服務提供方的身分識別資訊通常為使用者非常敏感的個人隱私資訊，還可將上述身分識別資訊加密後發布於區塊鏈的分散式資料庫中，以防止區塊鏈中的其他節點設備在獲取上述身分識別資訊後進行非法應用。
在又一示出的實施方式中，上述將身分識別資訊存證於區塊鏈的分散式資料庫中的具體方式還可以表現為，服務平台節點設備收集服務提供方的身分識別資訊，並將服務提供方的身分識別資訊的摘要(如雜湊摘要值)發送到區塊鏈的分散式資料庫中，以為上述服務提供方的身分識別資訊進行存證。
在本實施例中，區塊鏈的分散式資料庫中存證的服務提供方的身分識別資訊，用以供該服務提供方在提供服務時作身分校驗對比。關於上述身分校驗對比可以包括多種具體實現流程。
在一示出的實施方式中，上述身分校驗對比由上述服務平台節點設備執行，具體過程可包括：
當服務提供方接收到服務平台發送的訂單分配資訊後，會依據服務需求方的需求提供服務；在提供對應服務時，為了確保實際的服務提供方確實為上述訂單分配資訊指定的服務提供者，服務提供方或服務需求方終端會採集實際的服務提供方的現有身分識別資訊，如對實際的服務提供方進行人臉識別或查驗採集其身分證件等，並將上述採集到的現有身分識別資訊發送到服務平台節點設備，以供服務平台節點設備進行身分校驗對比；
上述服務平台節點設備接收上述服務提供方終端或上述服務需求方終端發送的身分校驗資訊後，基於區塊鏈中存證的、訂單分配資訊中對應的服務提供方的身分識別資訊，對上述存證的身分識別資訊與上述現有身分資訊進行對比；並將對比的結果發送至所述服務需求方終端或所述服務提供方終端，以使上述服務需求方確認此時實際的服務提供方和訂單分配資訊中指定的服務提供方是否為同一人。
在又一示出的實施方式中，上述身分校驗對比可由服務提供方終端或服務需求方終端執行。具體流程可包括：上述服務平台節點設備獲取所述服務提供方在所述區塊鏈的分散式資料庫中存證的身分識別資訊；向所述服務提供方終端或所述服務需求方終端發送所述身分識別資訊，以使所述服務提供方終端或所述服務需求方終端基於所述身分識別資訊，對所述服務提供方作身分校驗對比；接收所述服務提供方終端或所述服務需求方終端發送的身分校驗對比結果。
以上兩實施例僅是對服務提供方的身分資訊進行校驗對比的兩種具體實現方式，本說明書中並不限定基於區塊鏈的分散式資料庫中存證的服務提供方的身分識別資訊對實際的服務提供方進行身分校驗對比的實現過程及執行主體，凡是基於區塊鏈的分散式資料庫中存證的服務提供方的身分識別資訊對實際的服務提供方進行身分校驗對比以獲得身分校驗對比結果，均屬於本說明書保護的範圍。
步驟106，接收所述服務需求方終端或所述服務提供方終端發送的服務提供方實際提供的服務內容。
具體來說，上述服務提供方實際提供的服務內容可包括：服務提供方節點設備的定位資訊(用以表明服務提供方已達到服務位置)、所述服務提供方的身分校驗對比結果(用以表明服務提供方為訂單分配資訊中指定的服務提供方)、服務提供方開始服務時間、服務提供方結束服務時間、服務過程備忘資訊等內容中的一種或多種。
關於上述服務提供方實際提供的服務內容可以由所述服務需求方終端發送，也可由所述服務提供方終端發送，視實際業務需求或流程而定，在本說明書中不作限定。
步驟108，向所述區塊鏈發送服務存證交易，以使所述服務存證交易被所述區塊鏈共識驗證後收錄於所述區塊鏈的分散式資料庫；所述服務存證交易用於為服務提供方實際提供的服務內容進行存證。
在本說明書中所描述的交易(transfer)，是指透過區塊鏈的節點設備創建，並需要最終發布至區塊鏈的分散式資料庫中的一筆資料。其中，區塊鏈中的交易，存在狹義的交易以及廣義的交易之分。狹義的交易是指使用者向區塊鏈發布的一筆價值轉移；例如，在傳統的比特幣區塊鏈網路中，交易可以是使用者在區塊鏈中發起的一筆轉帳。而廣義的交易是指使用者向區塊鏈發布的一筆具有業務意圖的業務資料；例如，本說明書的上述實施例所述的發布至上述區塊鏈中的、用於為服務提供方實際提供的服務內容進行存證的資料即可以為一筆交易；或者將上述已完成的服務內容按照預設的交易資料格式整理，從而轉化為一筆交易。
本實施例所述的服務存證交易，用於為服務提供方實際提供的、或已完成的服務內容進行存證。例如，服務提供方終端或服務需求方終端可以從服務提供方達到服務位置開始，將服務提供方提供的一系列相關服務內容、或執行的一系列相關服務動作上傳到上述服務平台節點設備，既可使上述服務平台節點設備監管服務提供方提供的服務內容，又可使上述服務平台節點設備將上述提供方實際提供的服務內容在區塊鏈的分散式資料庫中進行存證。
具體來說，上述服務提供方實際提供的服務內容可包括：服務提供方節點設備的定位資訊(用以表明服務提供方已達到服務位置)、所述服務提供方的身分校驗對比結果(用以表明服務提供方為訂單分配資訊中指定的服務提供方)、服務提供方開始服務時間、服務提供方結束服務時間、服務過程備忘資訊等內容中的一種或多種。對應地，上述服務存證交易可包括上述服務提供方實際提供的服務內容的原文或加密密文，或上述服務提供方實際提供的服務內容的數學摘要(如雜湊摘要)，以為上述服務提供方實際提供的服務內容進行存證。
上述實施例所述的將所述服務存證交易上傳到所述區塊鏈的分散式資料庫中的詳細過程，可依據所述區塊鏈的共識機制及交易規則而具體設定。在一示出的實施例中，將所述服務存證交易上傳到所述區塊鏈的分散式資料庫中，包括：
所述區塊鏈中具有記帳權限的節點設備將所述服務存證交易加入到候選區塊；
從所述具有記帳權限的節點設備中確定滿足所述區塊鏈共識機制的共識記帳節點設備；
所述共識記帳節點向所述區塊鏈的節點設備廣播所述候選區塊；
在所述候選區塊透過所述區塊鏈符合預設數量的節點設備的驗證認可後，所述候選區塊被視為最新區塊，加入到所述區塊鏈的分散式資料庫中。
在上述的實施例中，具有記帳權限的節點設備是指具有產生候選區塊權限的節點設備。根據所述區塊鏈的共識機制，可從所述候選區塊具有記帳權限的節點設備中確定共識記帳節點設備，上述共識機制可以包括工作量證明機制(PoW)、或權利證明機制(PoS)、或股份授權證明機制(DPoS)等。
PoS或DPoS共識機制與PoW類似，均屬於公有區塊鏈中確認共識記帳節點設備所常選用的共識演算法。在又一示出的實施例中，為降低交易或資料的確認時間、提高交易輸送量、滿足對安全和性能的需求，本說明書所提供的實施例還可選用聯盟鏈架構來構建該區塊鏈。上述服務平台節點設備、或對相關服務業務實行監管的機構可作為該聯盟鏈的預選的節點設備，參與區塊的記帳。聯盟鏈的共識過程也由該預選的節點設備控制，當網路上有超過設定比例(如2/3)的節點設備確認一個區塊，該區塊記錄的交易或資料將得到全網確認。
聯盟鏈通常多採用權益證明或PBFT、RAFT等共識演算法。在實現時，在區塊鏈的每一輪共識開始之前，可以在區塊鏈中的各節點設備中選舉出一台主節點設備，即上述實施例所述的共識記帳節點(比如，每一輪共識都重新選舉出一主節點設備，其它節點設備作為從節點設備)，由主節點設備進一步向發起交易的驗證和共識，並負責基於共識通過的交易資料(或目標資料)為區塊鏈創建最新的區塊。
PBFT演算法作為本說明書所提供的聯盟鏈的共識演算法的一種優選的實施方式，是由於採用該種演算法共識的效率高，可滿足高頻交易量的需求，例如在本實施例中服務平台基於頻繁發生的訂單資訊而產生服務存證交易；且共識的時延很低，基本達到即時處理的要求，能快速即時地在區塊鏈的新生區塊中收錄上述服務存證交易；而且，將聯盟鏈網路中可信節點作為預選的記帳節點，兼顧了安全性與穩定性；另外，採用PBFT演算法不會消耗過多的電腦算力資源，也不一定需要代幣流通，因此具有良好的可使用性。
基於本實施例提供的服務方法，基於區塊鏈技術的分散式資料庫儲存機制，實際完成的服務內容被去中心化地記錄在多個區塊鏈節點中，由區塊鏈節點共同維護，即時進行同步，所有記錄可回溯；而且，基於區塊鏈的共識機制，服務平台節點設備提供的已完成的服務內容資訊不會在提供後被篡改，從而保證了已完成的服務內容的真實性和安全性，為基於該已完成的服務內容進行的取證或其他應用提供了有效的資料基礎。
與上述流程實現對應，本說明書的實施例還提供了基於區塊鏈的資料處理裝置20。該裝置20可以透過軟體實現，也可以透過硬體或者軟硬體結合的方式實現。以軟體實現為例，作為邏輯意義上的裝置，是透過所在設備的CPU(Central Process Unit，中央處理器)將對應的電腦程式指令讀取到記憶體中運行形成的。從硬體層面而言，除了圖3所示的CPU、記憶體以及記憶體之外，網路風險業務的實現裝置所在的設備通常還包括用於進行無線信號收發的晶片等其他硬體，和/或用於實現網路通訊功能的板卡等其他硬體。

With the development of Internet technology, network-based service models are constantly being introduced. For the server and the served person who are not acquainted with each other, the unfamiliarity between each other may bring a lot of security risks. This security risk is especially prominent in service modes such as remote service or on-site service.
Based on the technical status and problems raised above, FIG. 1 is a data processing method based on a blockchain shown in an embodiment provided in this specification, and the blockchain includes a service platform node device.
The service platform described in this embodiment may include a platform service organization that accepts a certain type of service demand or service provision of users, and performs services such as service matching or service distribution, such as on-site services (such as housekeeping services, maintenance services, Family education service) business matching platform, remote service (such as remote teaching) business matching platform, etc., are not limited in this manual.
The blockchain described in this embodiment can specifically refer to a P2P network system with a distributed data storage structure that is reached by each node through a consensus mechanism. The data in the blockchain is distributed in time and connected one by one. Within "block", the next block contains the data summary of the previous block, and according to the specific consensus mechanism (such as POW, POS, DPOS or PBFT, etc.), all or part of the node data is complete Backup. Those skilled in the art are well aware that since the blockchain system operates under the corresponding consensus mechanism, the data that has been included in the blockchain database is difficult to be tampered with by any node. For example, a blockchain using Pow consensus requires at least full Only 51% of the network's computing power can tamper with existing data. Therefore, the blockchain system has the characteristics of ensuring data security and preventing attack and tampering that other centralized database systems cannot match. It can be seen from this that in the embodiments provided in this specification, the data included in the distributed database of the blockchain will not be attacked or tampered with, thereby ensuring that the above-mentioned service platform node device can deposit the certificate on the above-mentioned blockchain The true reliability of the information.
The service platform node device described in this embodiment can join the blockchain as a node of the blockchain by following the installation of the corresponding node agreement and running the node agreement program. Those skilled in the art usually refer to a node device with full backup of the data of the blockchain distributed database as a full node, and will have partial backup data of the blockchain distributed database (such as data with only the block header) The node device is called a light node or a user terminal; the service platform node device described in this embodiment may include the above-mentioned full node, light node or user terminal, as long as it is directly or indirectly connected to the above-mentioned blockchain and can send Or any device that obtains data from the distributed database of the blockchain can be referred to as the node device described in this embodiment.
As shown in Figure 1, the above-mentioned blockchain-based data processing method includes:
Step 102: The service platform node device obtains order information sent by a service demander terminal, where the order information includes the required service content.
The service demander terminal described in this embodiment sends order information to the service platform node device in the process of communicating with the service platform node device. The above-mentioned order information may include the service content required by the service demander, and the required service content includes: service type content, or conditions that the service provider should meet, etc., so that the service platform can perform services for both parties based on the above-mentioned order information Matching, matching, or distribution.
Step 104: Based on the order information, send order distribution information to the service provider terminal to distribute the service provider to the service demander terminal, wherein the distributed database of the blockchain stores the above-mentioned service The identity information of the provider is used for the identity verification and comparison of the service provider when providing services.
The identity information of the service provider is stored in the distributed database of the blockchain, which is used to verify the identity of the service provider who actually provides the service, and prevent the service provider registered in the above-mentioned service platform and the service provider. The service providers who actually provide services after the order do not belong to the same user, which may bring potential safety hazards.
The above-mentioned identity identification information may include identity document information (such as identity card picture, identity card number, etc.), biological identity identification information (such as fingerprints, facial features, voiceprints, iris, etc. identification information) to determine the identity of the service provider.
The service provider can enter the above-mentioned identity information into the service platform node device when registering as a service provider of the above-mentioned service platform, and the above-mentioned service platform node device can deposit the above-mentioned identity information on the distributed blockchain of the blockchain In the database. It is worth noting that there can be many specific ways to store the above-mentioned identity information in the distributed database of the blockchain. In addition to backing up the original text of the above-mentioned identity information to the distributed database of the blockchain, Each node equipment is backed up and maintained together; because the identity information of the above-mentioned service provider is usually very sensitive personal privacy information of the user, the above-mentioned identity information can also be encrypted and published in the distributed database of the blockchain to prevent Other node devices in the blockchain perform illegal applications after obtaining the above-mentioned identification information.
In another illustrated embodiment, the above-mentioned specific method of depositing the identity information in the distributed database of the blockchain can also be expressed as that the service platform node device collects the identity information of the service provider and combines The summary of the service provider's identity information (such as hash summary value) is sent to the distributed database of the blockchain to store the above-mentioned service provider's identity information.
In this embodiment, the identity information of the service provider stored in the distributed database of the blockchain is used for the service provider to perform identity verification and comparison when providing services. Regarding the above identity verification comparison, a variety of specific implementation procedures may be included.
In an illustrated embodiment, the aforementioned identity verification and comparison is performed by the aforementioned service platform node device, and the specific process may include:
When the service provider receives the order distribution information sent by the service platform, it will provide services according to the needs of the service demander; when providing corresponding services, in order to ensure that the actual service provider is indeed the service provider specified by the above order distribution information, The service provider or service demander’s terminal will collect the actual service provider’s current identity information, such as face recognition of the actual service provider or check and collect their identity documents, etc., and use the above-collected existing identity information Send to the service platform node device for identity verification and comparison of the service platform node device;
After the above-mentioned service platform node device receives the identity verification information sent by the above-mentioned service provider terminal or the above-mentioned service demander terminal, based on the identity information of the corresponding service provider in the order distribution information stored in the blockchain, The identity information of the deposit certificate is compared with the above-mentioned existing identity information; and the result of the comparison is sent to the terminal of the service demander or the terminal of the service provider, so that the above-mentioned service demander can confirm the actual service provider and Whether the service provider specified in the order distribution information is the same person.
In another embodiment shown, the aforementioned identity verification and comparison may be performed by the service provider terminal or the service demander terminal. The specific process may include: the above-mentioned service platform node device obtains the identification information of the service provider stored in the distributed database of the blockchain; sending to the service provider terminal or the service demander terminal The identity identification information, so that the service provider terminal or the service demander terminal can perform identity verification and comparison of the service provider based on the identity identification information; receive the service provider terminal or the service provider terminal The identity verification comparison result sent by the service demanding terminal.
The above two embodiments are only two specific implementation methods for verifying and comparing the identity information of the service provider. This specification does not limit the identity information of the service provider certified in the blockchain-based distributed database The implementation process and execution body of the actual service provider identity verification comparison, which is the identity information of the service provider certified in the blockchain-based distributed database, and the actual service provider identity verification comparison Obtaining the comparison result of identity verification is within the protection scope of this manual.
Step 106: Receive the service content actually provided by the service provider sent by the service demander terminal or the service provider terminal.
Specifically, the service content actually provided by the above-mentioned service provider may include: the location information of the service provider’s node equipment (used to indicate that the service provider has reached the service location), and the identity verification and comparison result of the service provider (used by To indicate that the service provider is the service provider specified in the order distribution information), the service provider’s starting time, the service provider’s ending service time, and service process memo information.
The service content actually provided by the above-mentioned service provider may be sent by the service demander terminal or the service provider terminal, depending on actual business requirements or processes, and is not limited in this specification.
Step 108: Send a service certificate transaction to the blockchain so that the service certificate transaction is included in the distributed database of the blockchain after being verified by the blockchain consensus; the service certificate The transaction is used to deposit evidence for the service content actually provided by the service provider.
The transfer described in this manual refers to a piece of data that is created through the node device of the blockchain and needs to be finally released to the distributed database of the blockchain. Among them, transactions in the blockchain are divided into narrow transactions and broad transactions. A narrowly defined transaction refers to a transfer of value issued by a user to the blockchain; for example, in a traditional Bitcoin blockchain network, a transaction can be a transfer initiated by the user in the blockchain. In a broad sense, a transaction refers to a piece of business data with business intent released by a user to the blockchain; for example, the above-mentioned embodiment of this specification released to the above-mentioned blockchain is used to actually provide service providers with The data for depositing the service content can be regarded as a transaction; or the completed service content can be sorted according to the preset transaction data format to convert it into a transaction.
The service deposit transaction described in this embodiment is used to deposit the service content actually provided or completed by the service provider. For example, a service provider terminal or a service demander terminal can upload a series of related service content provided by the service provider or a series of related service actions performed by the service provider to the above-mentioned service platform node device starting from the service provider reaching the service location. The service platform node device can supervise the service content provided by the service provider, and the service platform node device can also enable the service platform node device to store the service content actually provided by the provider in the distributed database of the blockchain.
Specifically, the service content actually provided by the above-mentioned service provider may include: the location information of the service provider’s node equipment (used to indicate that the service provider has reached the service location), and the identity verification and comparison result of the service provider (used by To indicate that the service provider is the service provider specified in the order distribution information), the service provider’s starting time, the service provider’s ending service time, and service process memo information. Correspondingly, the above-mentioned service deposit transaction may include the original text or encrypted ciphertext of the service content actually provided by the above-mentioned service provider, or the mathematical abstract (such as a hash abstract) of the service content actually provided by the above-mentioned service provider, so that the above-mentioned service provider The actual service content provided is recorded.
The detailed process of uploading the service certificate transaction to the distributed database of the blockchain described in the above embodiment can be specifically set according to the consensus mechanism and transaction rules of the blockchain. In an illustrated embodiment, uploading the service deposit transaction to the distributed database of the blockchain includes:
The node device with accounting authority in the blockchain adds the service deposit transaction to the candidate block;
Determine a consensus accounting node device that satisfies the blockchain consensus mechanism from the node devices with accounting authority;
The consensus accounting node broadcasts the candidate block to the node device of the blockchain;
After the candidate block meets the verification and approval of the preset number of node devices through the blockchain, the candidate block is regarded as the latest block and added to the distributed database of the blockchain.
In the foregoing embodiment, the node device with the accounting authority refers to the node device with the authority to generate candidate blocks. According to the consensus mechanism of the blockchain, the consensus accounting node device can be determined from the node devices with accounting authority in the candidate block. The above-mentioned consensus mechanism may include a proof of work mechanism (PoW) or a proof of right mechanism (PoS) , Or Share Authorization Proof Mechanism (DPoS), etc.
The PoS or DPoS consensus mechanism is similar to PoW, and both belong to the consensus algorithm commonly used by the public blockchain to confirm the consensus accounting node equipment. In another illustrated embodiment, in order to reduce the confirmation time of transactions or data, increase transaction throughput, and meet the requirements for security and performance, the embodiment provided in this specification can also use the alliance chain architecture to construct the block chain. The above-mentioned service platform node equipment or the institution that supervises related service businesses can be used as the pre-selected node equipment of the alliance chain to participate in block accounting. The consensus process of the alliance chain is also controlled by the pre-selected node device. When there are more than a set ratio (such as 2/3) of node devices on the network to confirm a block, the transaction or data recorded in the block will be confirmed by the entire network.
Consortium chains usually use proof of rights or consensus algorithms such as PBFT and RAFT. In implementation, before each round of consensus in the blockchain starts, a master node device can be elected from each node device in the blockchain, that is, the consensus accounting node described in the above embodiment (for example, each round of consensus A master node device is re-elected, and other node devices are used as slave node devices. The master node device further initiates transaction verification and consensus, and is responsible for creating the latest blockchain based on the transaction data (or target data) passed by the consensus. Block.
The PBFT algorithm, as a preferred implementation of the consensus algorithm of the alliance chain provided in this specification, is due to the high efficiency of the consensus algorithm and can meet the needs of high-frequency transaction volume. For example, in this embodiment, the service The platform generates service certificate transactions based on frequently occurring order information; and the consensus delay is very low, which basically meets the requirements of real-time processing, and can quickly and instantly include the above-mentioned service certificate transactions in the new block of the blockchain; and , The trusted node in the alliance chain network is used as the pre-selected accounting node, which takes into account security and stability; in addition, the use of PBFT algorithm will not consume too much computer computing resources, and does not necessarily require token circulation, so it has Good usability.
Based on the service method provided in this embodiment and the distributed database storage mechanism based on blockchain technology, the actual completed service content is decentralized and recorded in multiple blockchain nodes, which are jointly maintained by the blockchain nodes. Real-time synchronization, all records can be traced back; moreover, based on the consensus mechanism of the blockchain, the completed service content information provided by the service platform node equipment will not be tampered with after provision, thus ensuring the authenticity of the completed service content And security, it provides an effective data basis for forensics or other applications based on the completed service content.
