Detailed Description
The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments. It is understood that these embodiments are given solely for the purpose of enabling those skilled in the art to better understand and to 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 embodiments of the present invention may be implemented as a system, server, platform, method, and the like. In this document, it is to be understood that any nomenclature is used for distinction only, 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 of the invention.
According to one embodiment of the application, a blockchain access system is provided, which comprises a plurality of blockchain network nodes and a cache server, wherein the plurality of blockchain network nodes perform data synchronization based on a consensus mechanism and network connection.
The blockchain of the present embodiment may refer to a single blockchain network node (or called blockchain node), or may refer to a blockchain cluster. For a blockchain system comprising a plurality of blockchain network nodes, each node in the blockchain system is capable of independently performing consensus operations and accounting operations. The entire blockchain system agrees on transactions related to nodes in the system, and records the successful transactions agreed in the ledger of the blockchain system. Transactions associated with blockchain network nodes include, but are not limited to: transactions that occur within each node 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 the embodiments of the present application, please refer to fig. 1, where fig. 1 shows a schematic block diagram of a client and a blockchain access system of an embodiment of the present application. A client herein generally refers to a user client, an application layer, a module in a computer system for managing transactions, etc. that can interact with the blockchain access system with which the client can 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 a client 104 may implement access to the blockchain network nodes 101 through the cache server 102, or may implement direct access to the blockchain network nodes 101 through a blockchain network interface or by making the client 104 directly access to the blockchain system 103 to become one of the network nodes. Of course, to improve the efficiency of client 104 accessing blockchain network node 101, client 104 preferably accesses at least a portion of the data in blockchain network node 101 through cache server 102.
The cache server 102 may be a single or multiple servers or a cloud server, and the cache server 102 is a non-blockchain network node server that does not employ blockchain technology and does not join a blockchain system, but has a right to access (e.g., access operations including query, write, etc.) the blockchain network node 101. The cache server 102 may use existing internet technology and can handle large-scale simultaneous access or centralized access.
Based on the embodiment of the application, different from the prior art that a client directly accesses the blockchain network node in the blockchain technology, the application can effectively deal 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 with a network connection based on a consensus mechanism 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 device 201 is configured to cache at least a portion of data in the blockchain network node; the caching apparatus 201 may write at least a portion of data in the blockchain network node into the caching apparatus 201 synchronously according to a preset caching rule through any interaction device in the prior art that can interact with the blockchain network node.
According to a preferred embodiment of the present application, in order to facilitate a client to quickly access at least part of data in a blockchain network node in real time, 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 includes the latest data, wherein the latest data in the blockchain network node is synchronized into the caching device periodically or under a specific condition. Such as data related to electronic transactions, more specifically including the user's stock number, stock category, amount of funds, transaction price per transaction, transaction amount, etc.
The request acquiring device 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 that is an object of the access request sent by the client, 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 a manner of obtaining the access request by the request obtaining device 202 is not limited herein.
The request processing device 203 is configured to determine the type of the obtained access request, and perform an operation on the client 104, the caching 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 caching device 201.
Preferably, according to an 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 for querying specific data in a blockchain network node, looking up the specific data from the caching device; the specific data includes, but is not limited to, the latest data in the blockchain network node that has been synchronized into the cache device.
-if the specific data is found, returning information corresponding to the specific data to the client issuing the access request.
Thus, the cache server of the preferred embodiment of the present application can provide cache service for data input/output of the client and the blockchain network node, and by synchronously storing at least part of data in the blockchain network node in the cache server, the client can meet the requirement of implementing quick or real-time query through the cache server. That is, the client can directly query the related data through the cache server without directly performing access association with the blockchain system.
Further, for an access request for writing data to the blockchain network node by the client, the data to be written may be stored in the cache server first, and the cache server writes the written data to the network node in the blockchain system according to a speed that the blockchain system can carry, and returns information that "the data to be written has been written to the blockchain network node" to the client after writing to the network node.
Thus, preferably, according to an embodiment of the present application, the request processing device 203 is configured to specifically perform the following operations:
when the type of the access request is judged to be a request for writing data to a blockchain network node, writing data corresponding to the request for writing data into a cache device, returning first information corresponding to the write request to a client sending the access request, and sending the request for writing data to the corresponding blockchain network node;
for example, if the access request is a request for writing transaction service-related quotation data to a blockchain network node, the request processing device 203 writes the data related to the write request into the cache device 201 and returns the first information "quotation received" to the client that issued the access request, and sends the request for writing transaction service-related quotation 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, "a bid request has been written to a 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 issuing the access request. The second information is also, for example, "a bid request has been written to a 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 trading with an internal resource of an account of a user, the request processing device 203 is specifically configured to perform the following operations:
-when it is determined that the access request is a request to write quotation data to a blockchain network node, writing the quotation data to the caching device 201 and returning the received quotation data to the client that issued the request to write quotation data, and sending the quotation data to the corresponding blockchain network node;
-obtaining feedback corresponding to a request to write quote data from the corresponding blockchain network node;
-when feedback that the quote data has been written into the corresponding blockchain network node is obtained, returning information that the quote data has been written into the blockchain network node to the client issuing the request for writing quote data.
The internal resources of the user account may include digital assets, including but not limited to stocks, funds and other types, 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 assets may include two parts, namely, asset description information and asset use conditions, wherein the asset description information includes but is not limited to asset value and asset Identification (ID), the asset use conditions are used for setting conditions for using the assets, and the client is allowed to access the corresponding digital assets in the block chain only when the client provides information meeting the conditions so as to prevent illegal operations on the digital assets by illegal users, and the asset use conditions may be represented by character strings. Optionally, the digital asset may further comprise blockchain signature information and an asset key, the blockchain signature information being used to identify the legitimacy of the asset at its home blockchain network node, proving that the asset has been billed by the corresponding blockchain network node; the asset key is used to further enhance the security of the digital asset, which can only be operated by the client or/and the 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 device 202 obtains requests from multiple clients for writing quotation data into blockchain network nodes for trading in account internal resources of users, and the caching device 201 stores account internal resource information of the multiple client users, the request processing device is further configured to perform the following operations:
-determining whether the offer of the buyer and the offer of the seller to be traded are the same, if so, respectively executing a first configuration operation on the internal resources of the account of the buyer and a second configuration operation on the internal resources of the account of the seller according to the internal resources of the account corresponding to the buyer and the seller, writing the executed first configuration operation information and second configuration operation information into a cache device, and returning corresponding first transaction information to the client of the buyer and the seller;
-sending the executed first configuration operation information and second configuration operation information to corresponding blockchain network nodes;
-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 client of the buyer and the seller according to the obtained feedback.
In order to more clearly illustrate the above embodiments, a specific example is given below of a write request initiated by a client for trading an account internal resource, wherein the process of trading the account internal resource can be divided into two phases, namely a quotation phase and a matching trading phase.
Quotation stage
I. The client initiates a quotation request related to transaction to a cache server, the cache server stores data corresponding to the quotation request and returns 'quotation received' or 'quotation accepted' information to the client;
meanwhile, the cache server sends a request for writing data corresponding to the quotation request into the blockchain network node to the blockchain network node according to the speed which can be carried by the blockchain system;
and III, the cache server acquires the information that the data corresponding to the quotation request is written into the blockchain network node from the blockchain network node, and returns the information that the data corresponding to 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 "received bid" or "accepted bid" information and the "data corresponding to the bid request has been written into the blockchain network node" information to the client may be relatively long (related to the speed of the blockchain system).
Match transaction phase
I. The matching transaction occurs in a cache server, when the price quoted by the buyer and the price quoted by the seller in both transaction parties are the same, the cache server reduces the number of stocks or other sellable assets corresponding to the account of the seller and increases the corresponding funds of the account of the seller, and increases the number of stocks or other to-be-purchased assets corresponding to the account of the buyer and reduces the corresponding funds of the account of the buyer; and at the same time, the cache server returns the "transaction committed" information to the buyer and seller.
At the same time, the cache server issues a request to the blockchain system to write transaction related information (e.g., increase or decrease of stocks, assets, funds in I above) into the blockchain according to the blockchain system bearer speed.
And III, the cache server acquires the information that the transaction related information is written into the blockchain from the blockchain network node, and returns the information that the transaction is written into the blockchain network node to the client.
It should also be noted that the time interval between the cache server returning the "transaction committed" information to the client and the "transaction committed was written to the blockchain network node" information may be relatively long (related to the speed of the blockchain system).
When the cache server processes the matching transaction service, matching can be performed according to a predetermined rule, and the predetermined rule may be a rule commonly used in existing server matching transactions, or may be another rule. The process of the cache server processing the matching transaction business is illustrated below as a simple example of matching:
before matching a transaction, the cache server in turn receives a request for quote from the client A, B, C, D to initiate the transaction, as follows:
client A intends to buy 400 shares of stock, with 10 dollars per share quote;
client B intends to sell 300 shares of stock, and each share is quoted 10 yuan;
client C intends to sell 100 shares of stock, each share quoted 10 yuan;
client D intends to sell 200 shares of stock, with 15 dollars per share quote.
In a matching transaction, in a first step, the cache server may check the client's request for quotes and the resources within the client's user's account. For example, checking the quotation request and the resources in the account of the client A, and for the case that A intends to buy 4000 yuan of stock, the cache server checks whether the resources in the account of the user of the client A have funds larger than or equal to 4000 yuan, and if so, accepts the quotation request of the client A; otherwise, a reminder message such as "do not buy funds of 400 shares of stock" is sent to client a.
Secondly, the cache server judges whether the transaction which can match the client exists according to the sequence of receiving the quotation requests:
the buying request of the client A appears earliest, the selling request of the client B appears secondly and is the same as the price quoted by the client A, and then the cache server adds 300 shares of stock in the buyer account of the client A and reduces 3000 yuan of funds of the buyer account, and simultaneously reduces 300 shares of stock in the seller account of the client B and increases 3000 yuan of funds of the seller account;
next, for the 100 shares of stock demand that the client a has not committed, the cache server continues to determine whether the quote of the sell request of the client C is the same as the quote of the client a, and after determining that the quote is the same, the cache server continues to add 100 shares of stock and reduce 1000 dollars of the buyer in the buyer account of the client a, and simultaneously, reduce 100 shares of stock and increase 1000 dollars of the seller account in the seller account of the client C.
And by analogy, for 200 shares of stocks to be sold which are not traded by the client D, the cache server continues to match the stocks for trading according to a preset rule after receiving a quote request of buying the stocks by the corresponding client.
When the cache server completes the matching transaction service, as described in point ii in the matching transaction stage, the cache server sends a request for writing transaction-related information (e.g., change conditions and change results of increase or decrease of stocks, assets, and funds in the corresponding account of the client A, B, C) into the blockchain to the blockchain system according to the carrying speed of the blockchain system; when the cache server acquires the information that the transaction-related information of the client A, B, C has been written into the blockchain from the blockchain network node, the cache server returns "transaction settlement has been written into the blockchain network node" to the client A, B, C.
According to a preferred embodiment of the present application, in a case that the quotation data for trading for the account internal resources of the user or/and the operation information executed for the account internal resources of the user are not written into the blockchain network node but are written into the cache device: if the request acquiring device 202 acquires the operation information requested by the client to access the quotation data or/and the internal resource of the account for the user, the request processing device 203 returns the corresponding data stored in the cache device 201 to the client.
Specifically, in the "matching transaction stage" described above, there may be a client querying related information related to the transaction (for example, the latest transaction record, transaction price, transaction amount, assets of the seller and the buyer, and asset amount) before the transaction related information is written into 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 cache server is constructed between the client and the blockchain system, the embodiment of the application effectively solves the problem that a blockchain network cannot rapidly process a large number of concurrent accesses by utilizing the rapid processing capability of the cache server, and simultaneously ensures that all transaction information is recorded on the blockchain.
According to a preferred embodiment of the present application, the blockchain access system further comprises: a blockchain network interface 204 for providing a network interface for clients to directly access the blockchain network nodes. The network interface may be implemented using known techniques.
Therefore, the block chain access system can provide convenience for the client to quickly access the cache server, and does not refuse the requirement that the client directly inquires the information of the block chain network nodes.
In some cases, the related latest information that may be stored by the cache server based on direct interaction with the client is not written into the blockchain network node, that is, the cache server is not synchronized with the information of the blockchain network node at this time, and in this case, if the client directly performs a write operation on the blockchain network node when accessing the blockchain network node, in order to achieve synchronization of the related latest information corresponding to the query and write operation between the blockchain network node and the cache server as much as possible, the cache server is required to synchronize the related latest information with the blockchain network node before allowing the client to perform the write operation on the blockchain network node. When a client is allowed to write to a blockchain network node, in order to avoid inconsistent modification of the same data corresponding to the write in the cache server by other clients, the same data corresponding to the write in the cache server needs to be protected temporarily (i.e., the modification operation is not allowed, and only the read operation is allowed), and the write operation of the cache server on the relevant information cannot be recovered until the write operation of the client on the blockchain network node is completed and synchronized to the cache server. It can be seen that, in the above situation, if it is required that the blockchain network node synchronizes the written data to the cache server after completing the write operation, based on the characteristic that the synchronization of the plurality of blockchain network nodes is inefficient as mentioned in the background art, thereby resulting in a very long time spent in the whole process, which is contrary to the purpose of the present invention of using the cache server to improve the operation efficiency, therefore, for the purpose of maintaining the present invention of "improving the efficiency of the blockchain to deal with large-scale concurrent services (e.g., electronic transactions)", the client is not allowed to directly perform the write operation on the blockchain network node in this situation. Thus preferably, the embodiments of the present application are defined herein: when the client directly accesses the network node of the block chain, the write requests such as transaction and the like can not be directly realized, and only the requests such as query and the like can 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 apparatus of the present application may be implemented using Application Specific Integrated Circuits (ASICs) or any other similar hardware devices. In one embodiment, the software programs of the present application may be executed by a processor to implement the steps or functions described above. Likewise, the software programs (including associated data structures) of the present application may be stored in a computer readable recording medium, such as RAM memory, magnetic or optical drive or diskette and the like. Additionally, some of the 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 for a blockchain access system, where the blockchain access system includes a plurality of blockchain network nodes and a cache server, the plurality of blockchain network nodes perform data synchronization based on a consensus mechanism and network connection, and the cache server includes 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 network nodes of the block chain by a caching device;
step S302, a request acquisition device acquires an access request from a client for accessing a network node of the blockchain;
step S303, the request processing device determines the type of the obtained access request, and performs an operation on the client, the cache device, or/and the blockchain network node according to the determined type of the access request and based on the data cached in the cache device.
According to a preferred embodiment of the present application, at least a 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 includes the latest data, wherein the latest data in the blockchain network node is synchronized into the caching device periodically or under a specific condition.
