Detailed Description
The principles and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are presented merely to enable those skilled in the art to better understand and practice the invention and are not intended to limit the scope of the invention in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Those skilled in the art will appreciate that the embodiments of the invention may be implemented as a system, a server, a platform, a method, and the like. In this context, it is to be understood that any naming is used only for distinction and not in any limiting sense. The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments thereof.
According to one embodiment of the present application, a blockchain access system is provided that includes a plurality of blockchain network nodes that perform data synchronization based on a consensus mechanism and network connections, and a cache server.
The blockchain of the present embodiment may refer to a single blockchain network node (or blockchain node) or a blockchain cluster. For a blockchain system that includes multiple blockchain network nodes, each node in the blockchain system is capable of independently performing consensus operations and billing operations. The entire blockchain system performs consensus on transactions related to nodes in the system and records transactions for which the consensus is successful in the ledger of the blockchain system. Wherein transactions related to blockchain network nodes include, but are not limited to: transactions that occur within nodes in the blockchain system, and transactions that occur between nodes in the blockchain system and other blockchain system nodes or non-blockchain network nodes.
For a better understanding of the system of embodiments of the present application, please refer to fig. 1, which shows a schematic block diagram of a client and blockchain access system of an embodiment of the present application. Clients are broadly referred to herein as user clients that may interact with a blockchain access system, application layers, modules in a computer system for managing transactions, etc., with which the clients may communicate through a particular interface or network.
As shown in fig. 1, the blockchain access system includes a plurality of blockchain network nodes 101 and a cache server 102, where the plurality of blockchain network nodes 101 may be regarded as a blockchain system 103, and the client 104 may access the blockchain network nodes 101 through the cache server 102, or may directly access the blockchain network nodes 101 through a blockchain network interface or by directly accessing the client 104 into the blockchain system 103 to become one of the network nodes. Of course, in order to promote efficient access of the client 104 to the blockchain network node 101, the client 104 preferably enables access to at least a portion of the data in the blockchain network node 101 through the cache server 102.
Wherein the cache server 102 may be a single or multiple servers or cloud servers, the cache server 102 is a non-blockchain network node server that does not employ blockchain technology nor join a blockchain system, but has access (e.g., including access operations such as queries, writes, etc.) to the blockchain network node 101. The cache server 102 may employ existing internet technology and is capable of handling large-scale simultaneous access, centralized access, or the like.
Based on the embodiment of the application, unlike the prior art that the client directly accesses the blockchain network node, the application can effectively cope with large-scale simultaneous access or centralized access by adding the non-blockchain network node server between the blockchain network node and the client.
The blockchain access system of the present application will be described in detail below.
As described above, the blockchain access system of the present application includes a plurality of blockchain network nodes that perform data synchronization based on a consensus mechanism and network connections, and a cache server. Specifically, referring to fig. 2, the cache server includes: a cache device 201, a request acquisition device 202, and a request processing device 203.
The caching apparatus 201 is configured to cache at least a portion of data in the blockchain network node; the caching apparatus 201 may synchronously write at least a portion of the data in the blockchain network node into the caching apparatus 201 according to a preset caching rule through any interaction device capable of interacting with the blockchain network node in the prior art.
According to a preferred embodiment of the present application, in order to facilitate the client to quickly access at least part of the data in the blockchain network node in real time, the at least part of the data in the blockchain network node is divided into latest data and other data according to a specific classification rule, and the data cached in the caching device comprises the latest data, wherein the latest data in the blockchain network node is synchronized into the caching device periodically or under specific conditions. The latest data is, for example, data related to electronic transactions, and more specifically includes the number of shares, the category of shares, the amount of money, the price of each transaction, the number of transactions, etc. of the user.
The request acquiring means 202 is configured to acquire an access request from a client to access a blockchain network node; the access request may be obtained by the request obtaining device 202 from a blockchain network node, which is an object that the request obtaining device 202 sends the access request, or the request obtaining device 202 may directly receive the access request sent by the client to the cache server, or may obtain the access request from another third party device, where the manner in which the request obtaining device 202 obtains the access request is not limited.
The request processing device 203 is configured to determine a type of the obtained access request, and perform an operation on the client 104, the cache device 201, or/and the blockchain network node 101 according to the determined type of the access request and based on the data cached in the cache device 201.
Preferably, according to an embodiment of the present application, the request processing device 203 is configured to specifically perform the following operations:
-looking up specific data in the cache means when it is determined that the type of access request is a request for querying the specific data in a blockchain network node; the particular data includes, but is not limited to, the most recent data in the blockchain network node that has been synchronized into the caching device.
-If the specific data is found, returning information corresponding to the specific data to the client that issued the access request.
Therefore, the cache server of the preferred embodiment of the application can provide cache service for data input/output of the client and the blockchain network node, and the requirement of the client for realizing quick or real-time query through the cache server can be met by synchronously storing at least part of data in the blockchain network node in the cache server. That is, the client can directly implement the query of the related data through the cache server, and no direct access association with the blockchain system is required.
Further, for the access request that the client writes data to the blockchain network node, the application can store the data to be written in the cache server first, and the cache server writes the written data into the network node in the blockchain system according to the speed that the blockchain system can bear, and returns the information of "the data to be written into the blockchain network node" to the client after writing into the network node.
Thus, preferably, according to one embodiment of the present application, the request processing device 203 is configured to specifically perform the following operations:
-when it is determined that the type of the access request is a request to write data to a blockchain network node, writing data corresponding to the request to write data to a caching device and returning first information corresponding to the write request to a client that issued the access request, and sending the request to write data to the corresponding blockchain network node;
For example, if the access request is a request for writing transaction service related bid data to a blockchain network node, the request processing device 203 writes the data related to the write request into the caching device 201 and returns first information "bid received" to the client that issued the access request, and sends the request for writing transaction service related bid data to the blockchain network node to the corresponding blockchain network node.
-Obtaining feedback corresponding to the request to write data from the corresponding blockchain network node; the feedback is, for example, "bid request written to blockchain network node";
-when feedback is obtained that data corresponding to the request to write data has been written to the corresponding blockchain network node, returning second information corresponding to the write request to the client that issued the access request. The second information is, for example, "the bid request has been written to the blockchain network node".
It should be noted that, the time interval between the cache server returning the first information and the second information to the client may be relatively long (the time interval is mainly related to the speed of the blockchain system).
According to a preferred embodiment of the present application, when the data corresponding to the request for writing data is quotation data for conducting a transaction with respect to an account internal resource of the user, the request processing means 203 is specifically configured to:
-when it is determined that the access request is a request to write bid data to a blockchain network node, writing the bid data to a caching device 201 and returning information that the bid data has been received to the client that issued the request to write bid data, and sending the bid data to the corresponding blockchain network node;
-obtaining feedback corresponding to a request to write bid data from the corresponding blockchain network node;
-when feedback is obtained that the quotation data has been written to the corresponding blockchain network node, returning information of the quotation data written to the blockchain network node to the client that issued the request to write quotation data.
Wherein the user's account internal resources may include digital assets, including but not limited to stock, funds, etc., which may be generated on any blockchain network node and may be embodied in the form of user account ID + account amount.
Alternatively, the digital asset may include two parts, asset description information and asset usage conditions, wherein the asset description includes, but is not limited to, asset value, asset Identification (ID), asset usage conditions are used to set conditions for using the asset, and the client is allowed to access the corresponding digital asset in the blockchain when the client provides information conforming to the conditions, so as to prevent illegal users from performing illegal operations on the digital asset, and the asset usage conditions may be represented by a character string. Optionally, the digital asset may further include blockchain signature information for identifying the legitimacy of the asset on its home blockchain network node, proving that the asset has been billed by the corresponding blockchain network node, and an asset key; the asset key is used to further enhance the security of the digital asset that can be operated upon by the client or/and blockchain network node holding the private key corresponding to the asset key.
According to a preferred embodiment of the present application, when the request obtaining means 202 obtains requests from a plurality of clients for writing bid data for transactions with account internal resources of users into a blockchain network node, and the cache means 201 stores account internal resource information of the plurality of client users, the request processing means is further configured to:
-determining whether the offer of the buyer to be transacted is the same as the offer of the seller, if so, respectively executing a first configuration operation of the account internal resources of the buyer and a second configuration operation of the account internal resources of the seller according to the account internal resources corresponding to the buyer and the seller, writing the executed first configuration operation information and second configuration operation information into a caching device, and returning corresponding first transaction information to clients of the buyer and the seller;
-sending the performed first configuration operation information and second configuration operation information to the corresponding blockchain network node;
-obtaining feedback for first configuration operation information and second configuration operation information from the corresponding blockchain network node;
-returning corresponding second transaction information to the buyer's clients based on the obtained feedback.
To more clearly illustrate the above embodiments, a specific example of a write request initiated by a client for a transaction with an account internal resource is described below, where the process of transacting with an account internal resource may be divided into two phases, a quotation phase and a matching transaction phase.
Quotation stage
I. The client initiates a transaction related quotation request to a cache server, the cache server stores corresponding data of the quotation request and returns information of 'quotation received' or 'quotation accepted' to the client;
Simultaneously, the cache server sends a request for writing the data corresponding to the quotation request into the blockchain network node according to the speed which can be borne by the blockchain system;
And III, the cache server acquires information of 'the corresponding data of the quotation request is written into the blockchain network node' from the blockchain network node, and returns the information of 'the corresponding data of the quotation request is written into the blockchain network node' to the client.
It should be noted that, the time interval between the cache server returning the information of "received bid" or "accepted bid" and the information of "corresponding data of bid request has been written into the blockchain network node" to the client may be relatively long (related to the speed of the blockchain system).
Matching transaction stage
I. When the quotation of the buyer and the quotation of the seller are the same in both transaction sides, the caching server reduces the corresponding stock or other marketable assets of the seller account and increases the corresponding funds of the seller account, and simultaneously increases the corresponding stock or other assets to be purchased of the buyer account and reduces the corresponding funds of the buyer account; and at the same time, the cache server returns "transaction completed" information to the buyer and seller.
And simultaneously, the cache server sends a request for writing transaction related information (such as stock, asset and increase or decrease of funds in the step I) into the blockchain system according to the bearing speed of the blockchain system.
And III, the cache server acquires the information of the transaction related information written into the blockchain from the blockchain network node, and returns the information of the transaction written into the blockchain network node to the client.
It should also be noted that the time interval between the cache server returning the information of "transaction completed" and the information of "transaction completed written to the blockchain network node" to the client may be relatively long (related to the speed of the blockchain system).
When the cache server processes the matching transaction service, the matching can be performed according to a preset rule, wherein the preset rule can be a rule commonly used in the existing server matching transaction or other rules. The process of the cache server processing the matching transaction traffic is described below in a simple example of matching:
before matching transactions, the cache server sequentially receives bid requests from clients A, B, C, D to initiate transactions, as follows:
Client a intends to buy 400 stocks, 10 yuan per stock quote;
client B intends to sell 300 shares of stock, 10 yuan per stock quote;
Client C intends to sell 100 shares of stock, 10 yuan per stock quote;
client D intends to sell 200 shares of stock, 15 yuan per stock quote.
In a matching transaction, in a first step, a cache server may examine a client's bid request and the client's user's account internal resources. For example, checking the request for quotation and the account internal resource of the client a, for a stock for which a is intended to buy 4000 yuan, the cache server checks whether the account internal resource of the user of the client a has funds greater than or equal to 4000 yuan, and if so, accepts the request for quotation for the client a; otherwise, a reminder message such as "no funds to buy 400 shares of stock at full rate" is sent to the client a.
The second step, the cache server judges whether the transaction which can match the client exists according to the order of receiving the quotation requests:
The buying request of the client A appears earliest, the selling request of the client B appears next and is the same as the quotation of the client A, the caching server increases 300 shares of stocks in the buyer account of the client A and reduces 3000 yuan of funds of the buyer account, and simultaneously decreases 300 shares of stocks in the seller account of the client B and increases 3000 yuan of funds of the seller account;
Next, for 100 shares of stock demand that the client a has not yet completed, the cache server continues to determine whether the offer requested by the sell of the client C is the same as the offer of the client a, and after determining that the offer is the same, the cache server continues to increase 100 shares of stock and decrease 1000 funds of the buyer in the buyer account of the client a, while decreasing 100 shares of stock and increasing 1000 funds of the seller account in the seller account of the client C.
And so on, for 200 shares of stocks to be sold which are not yet traded by the client side D, the caching server continuously matches the stocks according to a preset rule after receiving the request of the corresponding client side for buying the stocks.
When the cache server completes the matching transaction, the cache server sends a request for writing transaction related information (such as a change condition of increasing or decreasing stocks, assets, funds, and a change result in the corresponding account in the client A, B, C) into the blockchain according to the blockchain system bearing speed as described in the second point in the matching transaction stage; and, when the cache server obtains the information of "the client A, B, C has written the transaction related information into the blockchain" from the blockchain network node, the "transaction has written the blockchain network node" is returned to the client A, B, C accordingly.
According to a preferred embodiment of the present application, in case the quotation data for the transaction for the account internal resource of the user or/and the operation information performed for the account internal resource of the user has not been written to the blockchain network node but has been written to the caching device: if the request acquiring means 202 acquires the request from the client to access the offer data or/and the operation information executed on the resources inside the account of the user, the request processing means 203 returns the corresponding data stored in the caching means 201 to the client.
Specifically, in the "matching transaction stage" described above, there may be a client that queries related information related to the transaction (e.g., latest transaction records, transaction prices, transaction amounts, assets of sellers and buyers, amounts of funds, etc.) before the related information of the transaction is written to the blockchain network node, and if the cache server modifies the related information related to the transaction, the cache server returns the modified latest transaction information to the client.
Because the embodiment of the application constructs the cache server between the client and the blockchain system, the problem that the blockchain network cannot rapidly process a large number of concurrent accesses is effectively solved by utilizing the rapid processing capability of the cache server, and all transaction information is ensured to be recorded on the blockchain.
According to a preferred embodiment of the present application, the blockchain access system further includes: the blockchain network interface 204 is used to provide a network interface for clients to directly access blockchain network nodes. The network interface may be implemented using known techniques.
Therefore, the blockchain access system of the application not only can provide convenience for the client to quickly access the cache server, but also does not reject the requirement of the client for directly inquiring the blockchain network node information.
In some cases, the cache server may not have written the relevant latest information stored in the blockchain network node based on the direct interaction with the client, i.e. the cache server is not synchronized with the information of the blockchain network node at this time, but in this case if the client directly writes to the blockchain network node when accessing the blockchain network node, in order to achieve the synchronicity between the blockchain network node and the cache server of the relevant latest information corresponding to the query and the write operation as much as possible, the cache server needs to synchronize the relevant latest information to the blockchain network node before the client is allowed to write to the blockchain network node. And when the client is allowed to perform the write operation on the blockchain network node, in order to avoid inconsistent modification of the same data corresponding to the write operation in the cache server by other clients, the same data corresponding to the write operation in the cache server needs to be temporarily protected (i.e. the modification operation is not allowed and only the read operation is allowed), and the write operation of the relevant information by the cache server can not be recovered until the write operation of the client on the blockchain network node is completed and synchronized to the cache server. It is obvious that in the above case, if the blockchain network node is required to synchronize the written data to the cache server after the completion of the write operation, the time spent for the whole process will be very long based on the characteristics of inefficiency of the blockchain network nodes due to the synchronization mentioned in the background art, which is obviously contrary to the purpose of improving the operation efficiency by using the cache server in the present application, so that the client is not allowed to directly perform the write operation on the blockchain network node in this case for the purpose of maintaining the "improving the efficiency of blockchain to cope with large-scale concurrent services (such as electronic transactions)" in the present application. Thus, preferred embodiments of the application are defined herein: when the client directly accesses the blockchain network node, write requests such as transactions and the like cannot be directly realized, and requests such as inquiry and the like can only be directly realized.
The above-described systems of the present application may be implemented in software and/or a combination of software and hardware, for example, the various means of the present application may be implemented using Application Specific Integrated Circuits (ASICs) or any other similar hardware devices. In one embodiment, the software program of the present application may be executed by a processor to perform the steps or functions described above. Likewise, the software programs of the present application (including associated data structures) may be stored on a computer readable recording medium, such as RAM memory, magnetic or optical drive or diskette and the like. In addition, some steps or functions of the present application may be implemented in hardware, for example, as circuitry that cooperates with the processor to perform various steps or functions.
According to another preferred embodiment of the present application, there is provided an access method of a blockchain access system, the blockchain access system including a plurality of blockchain network nodes and a cache server, the plurality of blockchain network nodes performing data synchronization based on a consensus mechanism and a network connection, the cache server including a cache device, a request acquisition device, and a request processing device.
Referring to fig. 3, the access method includes:
Step S301, caching at least a part of data in the blockchain network node by a caching device;
Step S302, the request acquisition device acquires an access request from a client for accessing a blockchain network node;
Step S303, the request processing device judges the type of the obtained access request, and executes the operation on the client, the caching device or/and the blockchain network node according to the judged type of the access request and based on the data cached in the caching device.
According to a preferred embodiment of the present application, at least part of the data in the blockchain network node is divided into latest data and other data according to a specific classification rule, and the data buffered in the buffering means comprises the latest data, wherein the latest data in the blockchain network node is synchronized into the buffering means periodically or under specific conditions.
