Detailed Description
The blockchain is essentially a decentralized database, which is a sequence of related blocks generated by cryptography, each block containing information about the entire network transaction over a period of time for verifying the validity of the information and producing the next block. The block chain is a technical scheme for collectively maintaining a reliable database in a decentralized and distrusted mode. Therefore, the blockchain can also be referred to as a nationwide accounting technology or a distributed general ledger technology.
Intelligent contracts are computer programs that can automatically execute the contract terms, and blockchains are considered a subversive technology, mainly because intelligent contracts can be implemented on blockchains. The intelligent contracts are not defined by the codes, are enforced by the codes, and are completely automatic and cannot intervene. Smart contracts are decentralized and do not rely on a single centralized server, but are distributed, stored on a blockchain, and run automatically through network nodes.
As shown in fig. 1, an embodiment of the present invention provides a logical architecture layer structure of a data interaction system based on a blockchain, which includes a client, a relay server, an intelligent contract, and a blockchain bottom layer, where the layer structures are specifically described as follows:
1. a client:
the client can be a browser or a desktop application program, and can also be a mobile phone APP and the like. The client is used for presenting data and providing a user operation interface, wherein the user operation interface can even comprise that the user directly submits the intelligent contract code. In addition, the client may also include wallet functionality, including transfer and private key management functions. The client in the invention takes desktop application as an example.
2. A relay server:
and connecting a whole node of the block chain and maintaining the data cache. The relay server can also provide services for data, including services before the client reads data, such as sorting data cache, establishing indexes, or performing classification, screening, sorting and other work according to the needs of users; but also services prior to write transactions to the blockchain. Even, as long as the user wishes, we can let the relay server record and analyze the user's habits and preferences, actively "feed" the data to the user. In general, the relay server acts as a proxy for the blockchain, serving as a data manager.
Meanwhile, the data manager is not necessary, the client can select different relay service providers according to own needs, and can also select to read data from the block chain or upload transactions directly through the client without using a relay.
The data interaction system takes an e-commerce platform system as an example, and in a traditional centralized e-commerce mode, data and platform functions are in a centralized server. In the architecture provided by the invention, data is in a block chain layer, data display and user data input are in a client, and a relay layer realizes preparation work before data reading. Thereby forming benign competition, being beneficial to the function splitting and the division of labor cooperation of the whole system and finally forming benign commercial ecology.
It is contemplated that in such a mode, if an e-commerce system is implemented, all data becomes a blockchain public account and is not monopolized by any e-commerce platform. The e-commerce enterprises provide functions of data caching and data management, and a plurality of e-commerce enterprises can provide such services for clients, so as to form benign competition or form differentiated services. Data and service are separated, and more reasonable and efficient resource allocation is realized.
3. Intelligent contract: including various intelligent contracts in an application system.
4. Block chain bottom layer: and the system is responsible for distributed accounting functions, including services such as consensus algorithm, executor, network and communication.
The data interaction system provided by the invention is not limited to an e-commerce platform system, and can also comprise various existing application platform systems, such as a social platform system, a video application system and the like, which can be applied to most application systems.
In view of the description of the logical architecture layer structure of the system, the embodiment of the invention also provides a physical structure diagram of a data interaction system based on a block chain, as shown in fig. 2, the data interaction system based on the block chain comprises ① full nodes, namely common identification nodes, which are responsible for transaction common identification, accounting and complete account book storage of the whole block chain, ② a relay server node which is connected with the full nodes and periodically reads part of data concerned by a user from the block chain and performs pre-arrangement, including data classification, screening, sorting and user preference analysis so as to perform data pushing, and services before transaction chaining, such as format processing and sending to the block chain, ③ a client node which is responsible for data presentation, transaction data input, intelligent contract parameter input and other functions, the client node can read data through the relay server or directly read data from the full nodes, the client displays a plurality of relay service providers for the user to switch at any time, and the client also provides a relay switch, when the user does not trust the relay server, the relay service can be selected to be closed, the client and the data can be directly read and written in the block chain and directly pushed with the block chain, and the data interaction mode of the full chain is not shown in fig. 3.
Based on the logical architecture layer structure and the physical structure diagram of the data interaction system based on the block chain shown in fig. 1 and fig. 2 of the present invention, in the relay server provided by the present invention, a database table structure corresponding to the data interaction system is designed, as shown in the data schematic diagram of each node shown in fig. 3. The data interaction system of the embodiment takes an e-commerce platform application system as an example, designs forms Goods corresponding to commodities according to a commodity intelligent contract template, and stores corresponding data of the latest commodities. The fields of the Goods form are designed as attributes in the intelligent contract template of the commodity, such as commodity name, commodity contract address, seller ID, commodity quantity, commodity price and the like. Designing user interest tables (Interests) comprising the following fields: user ID, interest keyword, push switch, recommended goods, etc.
The relay server stores a database and the current height H of the synchronous block, inquires newly added blocks with the height greater than H on the block chain network at regular time intervals (such as 1 second), and if the height of the current block chain block is H ', reads all blocks with the heights from H +1 to H ' in the block chain, stores the transaction data in the newly added blocks into a corresponding table of the relay server database, and updates the height of the synchronous block to H '.
The following describes specific functions of the relay server, which takes an e-commerce platform system as an example, with reference to specific embodiments:
a first part: user search for merchandise
Step 1, a user inputs a commodity search condition such as a keyword 'Bluetooth headset' at a client side and requests to send to a relay server. And 2, the relay server searches the commodity table in the database according to the user condition and returns data. In order to improve the searching efficiency, some fields in the commodity table which are frequently used as searching conditions can be indexed.
A second part: user modification of merchandise attributes
Step 1: the seller A modifies the price of the commodity Good1 at the client and submits the modified price to the relay server;
step 2: the relay server packages the transaction, submits the request data to the blockchain according to a correct transaction format, calls a setPoint () method of a commodity intelligent contract Good1 in the blockchain, modifies the price attribute, and records a transaction ID: tx _ id and sets the highest block height for the transaction to be H _ limit;
and step 3: the blockchain processes the transaction;
step 4, the relay server reads new block data of a block chain according to a certain time interval and records the new block data into a relay database, if the data height of the new block obtained by the relay server in the current round is H1-H2, if ① H1< ═ H _ limit < ═ H2, the newly added blocks are traversed, if a transaction with a transaction ID of tx _ ID is found in the block data, the transaction is successfully uplink linked, the traversal is quitted, and the transaction result is notified to the client, step 5 is carried out, if the transaction is not found after the traversal is completed, the next round of synchronous block data result is waited, ② H _ limit < H1 indicates that the transaction is failed, the client is directly notified that the transaction is failed, step 5 is carried out, ③ H _ limit > H2, the new block is traversed, if the transaction ID of the transaction found in the new block is tx _ ID, the transaction is uplink linked, the traversal is successfully notified, the client is exited, the transaction result is waited for the next round of the transaction block data, and the transaction result is not found.
And 5: and (4) finishing.
And a third part: automatic data pushing function
Step 1, if the first part of users search commodities in step 1, the user B inputs a keyword 'Bluetooth headset' to search commodities and requests to send to a relay server. In step 2 of the first part, the relay server finds out the user B in the interest table while returning corresponding data, and adds a keyword "bluetooth headset" in the "interest keyword" column;
step 2: the relay server updates the column data of the 'recommended commodities' in the interest table periodically according to the transaction data on the block chain. Different relay server providers may employ different push data selection strategies. For example, the recommended product may be selected according to the transaction amount, or the related product that is newly updated may be selected as the recommendation. Namely, different relay service providers provide differentiated services, so that benign market competition is formed, and more choices are provided for users;
and step 3: when the user B is online, the relay server pushes the recommended commodity information of the user B in the interest table to the client;
and 4, step 4: when a user B wants to close the function, a request can be submitted at a client, the relay server updates the 'push switch' flag bit of the user in the interest table and sets the flag bit to False, when the relay server is in a closed state, the relay server does not push the recommended data to the client, and under the default condition, the 'push switch' flag bit in the interest table is 'True'.
The fourth part: turning off or selecting other relay servers
The client displays a plurality of relay service providers for the user to switch at any time.
The client also provides a relay switch, when the user does not trust the relay server, the relay service can be selected to be turned off, the data is read and written by the client and directly interacts with the blockchain, and the data pushing function is not provided.
