and S11, receiving the warehouse-in and warehouse-out transaction initiated by the first node in the current blockchain channel.
In the present application, the current blockchain channel is a pre-created private channel for the communication of the nodes on each blockchain. The current node, the first node and other nodes in the application need to be added into the current blockchain channel in advance, and after the current node, the nodes can share or manage all accounts in the current blockchain channel. In theory, a node may join multiple channels (i.e., own multiple ledgers), but the ledgers for each channel are isolated. Thus, a channel is a logical structure that consists of various nodes that physically exist.
Further, the first node is a transaction initiating node in the current blockchain channel, the current node is a transaction executing node, and the first node and the current node may be peer nodes (peer nodes).
The blockchain network is mainly composed of a series of peer nodes. The peer node is the basis of the whole network and is the carrier of the ledger and the intelligent contracts. Through the intelligent contract, the ledger records the whole process of the transaction in a non-falsifiable manner. In blockchains, intelligent contracts and ledgers are used to encapsulate shared processing engineering and shared information throughout the network.
Taking the application scenario of the pledge financing of the goods as an example, the first node is a peer node deployed in a bank. The node can initiate warehousing transaction when receiving a pledge financing application submitted by the terminal, or can initiate ex-warehouse transaction when receiving a pledge application submitted by the terminal. The current node is a peer node deployed in the warehousing party, and the node can receive warehousing transactions and ex-warehouse transactions initiated by the first node and execute corresponding transaction contents to obtain transaction results and transaction records.
In the present application, servers on various organizations need to be deployed in advance, organizations need to be created, and blockchain channels need to be created. Taking the application scenario of the material escorting and financing as an example, the nodes deployed in the bank, that is, the bank peer node and the bank orderer node, join the same organization, and the nodes deployed in the warehousing party, that is, the warehousing party peer node and the warehousing party orderer node, join the same organization. Nodes in each organization can join the same channel, and nodes after joining the same channel can share the account book of the channel.

And S13, sending the transaction record to the first node so that the first node can store the transaction record in a first ledger corresponding to the first node, and store the transaction record in a local second ledger.
In this application, the first account book is the account book held by the first node, and the second account book is the account book held by the current node. The first account book and the second account book are used for storing transaction records corresponding to each transaction in the current block chain channel. And synchronously updating data of the account book on each node in the same channel. When a channel comprises a plurality of nodes, each node is provided with an account book which records the transaction record of each transaction in the current blockchain channel, and the plurality of nodes are provided with one account book, so that distributed storage of the transaction records is formed, when the account book on one node is tampered, the data of the account book can be obtained from other nodes to recover the data, and the data tampering prevention is realized.
In a blockchain network, each peer node holds one or more ledgers, and one or more chain codes (smart contracts). Each peer node may access its respective ledger by a chain code.
And S14, when the transaction record in the second ledger is changed, acquiring the transaction record in the first ledger, and generating first prompt information according to the transaction record in the first ledger and the second ledger.
The application further provides a monitoring mechanism, which can monitor the change of the transaction record in the second account book on the current node, acquire the transaction record in the first account book when monitoring that the transaction record in the second account book changes, and generate first prompt information according to the transaction record in the first account book and the second account book.
The method and the device for the data tampering alarm further can generate first prompt information for the changed content of the second account book, and push the first prompt information to a terminal for display, so that the data tampering alarm visual interface is realized.

When the warehouse-in and warehouse-out transaction is warehouse-out transaction, warehouse-out information of the to-be-transacted goods is generated according to the warehouse-out transaction, the warehouse-out information is sent to the first node, confirmation information which is fed back after the first node verifies the warehouse-out information according to initial information of the to-be-transacted goods stored in advance is received, state information of warehouse-out completion is generated after warehouse-out is executed and serves as a transaction execution result, and a transaction record is generated according to the transaction execution result and the warehouse-out information.
The method can enter the page of the block chain-based item monitoring system through a specified network address. The user can perform related operations on the page, such as warehousing application, access application, warehousing examination, ex-warehouse examination and the like.
Taking the matter pledge financing as an example, the step of obtaining the transaction execution result according to the warehouse-in and warehouse-out transaction and generating the transaction record according to the transaction execution result is analyzed.
The financial and qualification party registers the article information of the article to be transacted with the bank in advance, and the bank registers the article information of the article to be transacted and inputs the article information into the article monitoring system based on the block chain. The user can complete login operation on the page, a warehousing application can be initiated after login, a peer node of a bank, namely a first node in the application, initiates a warehousing transaction after receiving the warehousing application, the warehousing transaction is sent to an order node (sequencing node) of the bank, the order node of the bank sends the warehousing transaction to a message distribution server, the warehousing transaction is sent to the peer node of a warehousing party, namely a current node of the application, through the message distribution server, and warehousing information is generated after the current node receives the warehousing transaction. Wherein, the warehousing information includes but is not limited to: item details of the item to be transacted, identification information of the storage warehouse, identification information of a monitoring device for monitoring the item to be transacted, identification information of the item to be transacted (such as an automobile identification), photo information or video information of the item to be transacted (which means that a photo and a video are stored in the warehouse after the item to be transacted is put in the warehouse).
Further, the current node sends the warehousing information to the order node of the warehousing party, the order node of the warehousing party sends the warehousing information to the message distribution server, and the message distribution server distributes the warehousing information to the first node and other nodes in the current block chain channel.
Further, after receiving the warehousing information, the first node verifies the warehousing information according to the initial information of the pre-stored articles. Specifically, the article details in the warehousing information are verified according to the article details in the initial information, the photo information and the video information in the warehousing information are verified according to the picture information and the video information in the initial information, if the verification is consistent, the verification is passed, the warehousing is agreed, otherwise, the verification is not passed, and the warehousing is rejected.
When the verification is passed, the first node sends the information of the notice of agreeing to warehousing to the order node of the bank, the order node of the bank sends the information of agreeing to warehousing to the message distribution server, and the message distribution server distributes the information of agreeing to warehousing to the current node and other nodes in the current block chain channel, so that the other nodes update the transaction state to respective accounts.
Further, after receiving the notification information of agreeing to warehousing, the current node generates reminding information and pushes the reminding information to a specified terminal to remind related workers who execute warehousing. After the workers finish warehousing, the warehousing-finished state information is recorded into the block chain-based article monitoring system and submitted to the current node, the current node receives the warehousing-finished state information, transaction records and warehousing-finished notification information are generated, and the transaction records and the warehousing-finished notification information are distributed to the first node and other nodes in the current block chain channel through the message distribution server, so that the transaction records are stored into respective accounts of the first node and other nodes.
In the present application, the message distribution server may be a kafka (message distribution system) cluster. The method and the device ensure high performance of the system by utilizing high throughput of the kafka cluster.
In one embodiment, the generating the first prompt information according to the first account book and the second account book includes:
and comparing the transaction record in the second account book with the transaction record in the first account book to obtain difference information, and generating first prompt information according to the difference information.
In this application, when the transaction record in the second ledger is changed, the following changes may be specifically included:
firstly, the content of the transaction record is deleted;
secondly, the content of the transaction record is modified;
third, transaction records are increased.
In the application, the current node can monitor the change of the transaction record in the second account book, when the change of the transaction record in the second account book is monitored, the transaction record in the first account book is obtained, and first prompt information is generated according to the transaction record in the first account book and the second account book.
In one possible design, monitoring the second ledger for changes in the transaction records may include the following:
monitoring whether the transaction record in the second account book is deleted;
monitoring whether the transaction record in the second ledger is modified;
and monitoring whether the transaction records in the second account book are newly added.
Wherein monitoring deletion and modification of transaction records in the second ledger can be monitored by a chained data structure of the blockchain. Generally, there is a certain correlation between data in each block in the block chain, and whether the transaction records in the blocks are changed or not can be monitored based on the correlation. Of course, the transaction record change may be monitored in other ways, and is not limited in any way.
