SERVICE AND APPLIANCE PROCESSING METHOD
FIELD OF TECHNIQUE [001] This application relates to the field of computer technologies and, in particular, to a method and apparatus for processing transactions.
BACKGROUND OF THE INVENTION [002] Blockchain technologies are also known as distributed accounting technologies. Blockchain technologies have attracted a lot of attention since their inception, due to features such as immutability and decentralization of data stored using these technologies. With the continued development of computer technologies, blockchain technologies will provide people with an increasingly secure data storage environment and convenience for data storage.
[003] In an exemplary application, blockchain technologies are typically used to store transaction information generated in a transaction. However, the emergence of smart contracts further expands the range of blockchain services. A smart contract is typically a segment of codes stored on a blockchain (or a transaction processing node on the blockchain). The execution conditions and transaction processing logic of the smart contract are prescribed in the code segment. Namely, for a transaction processing request, conditions are prescribed to invoke the smart contract and how to process a transaction processing request received after the smart contract is invoked. Therefore, when a user needs to process a designated transaction through a smart contract, the user can send a transaction parameter needed to process the designated transaction to a transaction processing node on a blockchain, leading the transaction processing node to execute the transaction parameter when the transaction parameter is determined for
Petition 870190066689, of 7/15/2019, p. 10/62
2/39 meet an execution condition prescribed by the smart contract and then to complete the job of processing the designated transaction.
[004] For example, when a user needs to process some designated transactions through a smart contract, a smart contract storage address on the blockchain can be carried in a transaction processing request, taking a transaction processing node on the blockchain to determine the transaction parameter and storage address of the smart contract on the transaction processing request blockchain when the transaction processing request is executed. Depending on the storage address, the transaction processing node can call the smart contract stored at the storage address and determine whether the transaction parameter meets the smart contract execution condition. If so, the transaction processing node processes the transaction parameter according to the transaction processing logic pre-prescribed in the smart contract, in order to complete the job of processing the designated transactions.
[005] Due to the characteristic that the data stored on a blockchain is immutable, it is impossible to change a smart contract, once the smart contract is stored on a blockchain. With continuous transaction updates, a smart contract may not be able to support the work of processing new (updated) transactions. In order to allow the smart contract to support the work of processing new transactions, the smart contract must be further developed according to the new transactions and replenished on the blockchain.
[006] Therefore, there is an urgent need for a transaction processing method to solve the blockchain problem that transaction processing methods are not flexibly adaptable to

DETAILED DESCRIPTION [020] To enable the person skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the modalities of the present invention will be described in a clear and complete manner below with reference to the accompanying drawings in the modalities of the present invention. It is obvious that the described modalities are only some, but not all, modalities of the present invention. Based on the modalities of the present invention, all other modalities that can be obtained by those skilled in the art without creative effort will fall within the scope of the present invention.
[021] Figure 1 is a schematic diagram of a transaction processing process according to some embodiments of the present invention, comprising the following steps:
[022] S101: receive a transaction request.
[023] In the embodiments of the present invention, an entity implementing the embodiments of the present invention may be a transaction processing node. The transaction processing node here is equipped with blockchain processing technology, that is, the transaction processing node
Petition 870190066689, of 7/15/2019, p. 15/62
7/39 transaction is able to process blockchain transactions. So, S101 can be interpreted as the transaction processing node that receives a transaction request.
[024] The transaction request can be interpreted as being sent by a user to the transaction processing node via a terminal device (the terminal device here can be interpreted as a mobile terminal, a PC terminal, etc.), or it can be considered as being sent by a server that has received a transaction request sent by a user (the server may be equipped with blockchain processing technology and capable of transmitting data with the transaction processing node), or it can even be interpreted as being sent by a server not equipped with blockchain processing technology to the transaction processing node after the server receives a transaction request sent by a user, which is not limited by the modalities described here .
[025] For example, in a process of carrying out transaction processing, a user can enter corresponding transaction data in a terminal, such as a computer, a cell phone, etc., to trigger a transaction request. For example, when the user needs to perform a transfer transaction, the user can enter a transfer amount and a transfer recipient to a terminal, where the transfer amount and transfer recipient entered by the user and the transfer initiator ( that is, the user) may constitute transaction data for the user's transfer transaction. The user then sends the transaction request that transports the transaction data comprising the transfer amount, the transfer recipient and the transfer initiator to a transaction processing node. For another example, when a user needs to store data on a blockchain, the user can insert the data into a
Petition 870190066689, of 7/15/2019, p. 16/62
8/39 terminal, where the data is transaction data from the data storage transaction entered by the user and then the user sends a transaction request that transports the transaction data including data to be stored in a processing node transaction. The way in which the user sends the transaction request to the transaction processing node is not limited by the modalities described here.
[026] For another example, when a terminal detects that a user performs a designated operation (for example, by clicking on a designated control displayed on the terminal interface, etc.), the terminal can determine the user's transaction data entry in the terminal and generate a corresponding transaction request according to the transaction data and send the transaction request to a transaction processing node, causing the transaction processing node to receive the transaction request and process a target transaction included in the transaction. transaction request in a subsequent process. The way in which the user sends the transaction request to a transaction processing node is not limited by the modalities described here.
[027] It should be noted that in the transaction processing process in the modalities of the present invention, a user can enter corresponding transaction data in a terminal and can also enter the transaction data in a designated application installed on the terminal. Correspondingly, after the user has entered transaction data, the designated application can generate a corresponding transaction request. Then, when an operation designated by the user is detected (for example, clicking on a designated control, etc.), the designated application can send the transaction request to a transaction processing node.
[028] S102: determine a transaction type for a target transaction included in the transaction request.
Petition 870190066689, of 7/15/2019, p. 17/62
9/39 [029] After the transaction processing node receives the transaction request sent by the user through the terminal, the transaction processing node can further determine a transaction type of a target transaction included in the transaction request. This action is provided for the following purpose: in the modalities of the present invention, the transaction models are pre-stored in the transaction processing node and different transaction models correspond to different transaction processing jobs, therefore, after the transaction processing node transaction receives the transaction request sent by the user, the transaction processing node needs to determine which transaction model of pre-stored transaction models is capable of processing the target transaction included in the transaction request. The transaction processing node usually stores transaction templates corresponding to the transaction types. Therefore, in the process of determining which transaction model is capable of processing the target transaction included in the transaction request, the transaction processing node can determine the transaction type of the target transaction and determine the transaction model corresponding to the transaction type. . According to the pre-stored relationship between the transaction types and transaction models, in addition to processing the target transaction included in the transaction request through the transaction model in the subsequent process.
[030] In one example, after the transaction processing node receives the transaction request sent by the user, the transaction processing node can determine a transaction identifier of the target transaction included in the transaction request and determine the type of transaction of the target transaction according to the transaction identifier, where the transaction identifier can be a number chain and part of the number chain is a transaction code capable of representing the target transaction. For example, in the
Petition 870190066689, of 7/15/2019, p. 18/62
10/39 transaction # 244340923, # 2 is a transaction code code that represents a target transaction. The transaction identifier can also be in other forms. For example, when the transaction request comprises transfer type characters, transfer type is the transaction identifier of the target transaction included in the transaction request.
[031] It should be noted that the transaction models pre-stored in the transaction processing node according to the modalities of this request can be built through the API and stored in the transaction processing node.
[032] S103: Load, according to the type of transaction, a transaction model corresponding to the type of transaction.
[033] In the modalities of this application, the transaction templates corresponding to various types of transactions are pre-stored in the transaction processing node. Therefore, after the transaction processing node receives the transaction request sent by the user, the transaction processing node can load, according to the determined transaction type corresponding to the target transaction included in the transaction request, a corresponding transaction model. the transaction type of the pre-stored transaction templates. Then, in the subsequent process, the transaction processing node can process the target transaction using the transaction model.
[034] For example, assuming the user initiates a transfer request (that is, a transaction request) to the transaction processing node, after the transaction processing node receives the transfer request, the processing node You can review the transfer request and determine that the type of transaction corresponding to the transfer order is a transfer transaction. Then, the transaction the transaction processing node determines and loads a transfer model that
Petition 870190066689, of 7/15/2019, p. 19/62
11/39 corresponds to the transfer transaction (that is, the type of transaction) of the pre-stored transaction templates. In the subsequent process, the transaction processing node processes the transfer request using the transfer model.
[035] After the transaction processing node determines the transaction type of the target transaction included in the transaction request, the transaction processing node discovers that there is no transaction model that matches the transaction type in the pre transaction models -configured. That is, none of the transaction models is capable of processing the target transaction included in the transaction request. Then, the transaction processing node can generate a transaction model capable of processing the target transaction according to the transaction code entered by the user, and then process the target transaction using the generated transaction model.
[036] In one example, when the transaction processing node receives a transaction request sent by a user, the transaction processing node determines that there is no transaction model matching the transaction request in the preconfigured transaction models . The transaction processing node can then remind the user that the target transaction included in the transaction request cannot be processed. When the user sees the reminder, the user can compile a transaction code needed to process the target transaction on the transaction processing node for the target transaction and the transaction processing node can generate a corresponding transaction model according to the code transaction entered by the user. The transaction processing node can then load the generated transaction model and process the target transaction.
[037] In an example application, data formats that can be read by different transaction models are typically different. Therefore, after
Petition 870190066689, of 7/15/2019, p. 20/62
12/39 the transaction processing node receives a transaction request sent by a user in the modalities of this request, the transaction processing node can also read the transaction request sequentially through the pre-stored transaction templates. When the transaction processing node is able to read the transaction request using a transaction model (that is, the data format of the transaction request corresponds to the transaction model), the transaction processing node can process the target transaction included in the transaction request via the transaction template in the subsequent process.
[038] As the data on a transaction processing node can be changed, the pre-stored transaction templates on the transaction processing node can be updated and adjusted. Therefore, when a transaction is continuously updated, a user can update the transaction templates on the transaction processing node. The user does not need to develop a transaction model again, but only perform updates and adjustments based on the original transaction models, to allow the transaction models to support the updated transaction, significantly improving the efficiency of maintaining the transaction.
[039] However, as the data stored on the blockchain is immutable, the use of a blockchain by the user to store data will effectively guarantee the security of the data storage, thus providing an advantageous verification base for the subsequent data verification by the user. On the other hand, data immutability also leads to drawbacks in processing transactions for a blockchain, and one of the most significant problems is that smart contracts that currently support expansion of the blockchain transaction are typically stored on the blockchain and therefore smart contracts may not be updated with ongoing transaction updates. For
Petition 870190066689, of 7/15/2019, p. 21/62
13/39 allow smart contracts to support the work of processing new transactions, the user needs to develop the smart contracts again and save the revised smart contracts on the blockchain. Therefore, continuous transaction updates will inevitably force the user to continue developing smart contracts, thus resulting in a significant inconvenience in maintaining the transaction for the user.
[040] In the modalities of the present invention, all transaction models for processing multiple target transactions can be pre-stored in a transaction processing node, instead of being stored in the blockchain. Therefore, when a transaction is updated, a user only needs to perform corresponding updates on the transaction templates stored in the transaction processing node to make the transaction templates capable of supporting the updated transaction. There is no need to re-develop transaction models to adapt to the updated transaction, and the cost of maintaining the transaction will be greatly reduced compared to current technologies, in which a user can only re-develop smart contracts to make smart contracts again support the transaction processing of an updated transaction. However, the problem is that transaction processing methods are not flexibly adaptable so that transaction updates are resolved and the flexibility of transaction processing on the blockchain is greatly improved.
[041] In addition, in exemplary applications, the system resources required in a smart contract execution process are generally allocated by a virtual machine. Since the virtual machine is split from a server, however, the virtual machine can only have a portion of the server system's resources. The allocation, by the virtual machine, of the system resources required
Petition 870190066689, of 7/15/2019, p. 22/62
14/39 by the smart contract means that the smart contract can only obtain required system resources from the server system resources owned by the virtual machine. In this way, the smart contract gets a small amount of system resources. To adapt to an increasingly high level of up-to-date transaction demand, however, the smart contract must need to obtain more system resources from the virtual machine to provide sufficient support for an increasing number of transactions. The performance problem of the virtual machine itself (that is, the virtual machine has a relatively small amount of system resources and the amount of system resources allocated to the smart contract is also relatively low) makes it impossible for the smart contract to provide good support for the increasing amount of transactions, thereby reducing the efficiency of blockchain transaction processing and resulting in inconvenience for users.
[042] In the modalities of the present invention, the transaction models corresponding to several transactions are pre-stored in a transaction processing node. In a transaction model initiation process to process a transaction request, the transaction processing node can allocate more system resources to the transaction request processing process, as the transaction processing node has the same amount system resources than a server. Therefore, with a continuous increase in the number of transactions, the transaction processing node can still strongly support the processing of multiple transactions, thus ensuring the efficiency of blockchain transaction processing.
[043] S104: Process the target transaction according to the transaction model and record the transaction information obtained from the processing on a blockchain.
[044] After the transaction processing node determines the model
Petition 870190066689, of 7/15/2019, p. 23/62
15/39 transaction corresponding to the type of transaction, the transaction processing node can process the target transaction included in the transaction request via the transaction model, where the transaction model comprises a pre-prescribed transaction processing rule , and the transaction processing node can process the target transaction according to the transaction processing rule.
[045] In exemplary applications, each type of transaction typically includes several sub-transactions. For example, financial transactions may include sub-transactions, such as transfer transactions, financial management transactions, etc., on the basis of which, in the modalities of this order, a transaction processing rule in each transaction model may be responsible for processing transactions of a main type of transactions, while each processing rule comprises a plurality of processing rules with different processing rules and different sub-transactions in the types of transactions. For example, for financial transactions, the transaction processing node can store the transaction model responsible for processing the financial transaction, while the financial transaction model comprises several processing rules for transferring processing, financial management and other sub-transactions.
[046] Therefore, in the modalities of this request, after loading the transaction processing node loads, according to the transaction type of the target transaction included in the transaction request, a transaction model corresponding to the type of transaction, the Transaction processing can determine a transaction processing rule included in the transaction model. The transaction processing node can then further determine a processing rule that matches the target transaction from the processing rules included in the transaction processing rule and
Petition 870190066689, of 7/15/2019, p. 24/62
16/39 process the target transaction using the processing rule.
[047] For example, assuming that the transaction request received by the transaction processing node is a transfer request sent by the user, the transaction processing node can determine that the transaction request transaction type is financial. The transaction processing node can then determine and load a transaction model capable of processing financial transactions from the pre-stored transaction models. After the transaction processing node loads the transaction model, the transaction processing node can determine a transaction processing rule included in the transaction model. The transaction processing node can then determine a transfer processing rule (that is, the processing rule described above) that matches the transfer transaction from the processing rules included in the transaction processing rule and process the transaction from transfer through the processing rule.
[048] In example applications, transaction requests entered by a user in a transaction processing node can create situations such as the data format in accordance with the provisions, illegal transaction request, etc. When the transaction processing node processes these transaction requests with problems, the operations of the transaction processing node can be affected, and the transaction processing node can even collapse in severe situations.
[049] To ensure effective transaction processing node operations and to ensure efficient transaction processing node transaction transactions, under the terms of this request, the transaction processing node may verify a transaction request received in accordance with the determined transaction model (the transaction model being
Petition 870190066689, of 7/15/2019, p. 25/62
17/39 used to process the transaction request received by the transaction processing node).
[050] In one example, after the transaction processing node determines the transaction model corresponding to the transaction request (that is, the transaction model corresponding to the transaction type of the target transaction), the transaction processing node can determine a transaction processing rule included in the transaction model of the transaction model, where the transaction processing rule comprises processing rules for performing transaction processing and checking rules for checking transaction requests. Therefore, the transaction processing node can verify the transaction request according to the verification rules. When the transaction processing node determines that the transaction request meets a predefined condition prescribed in the verification rules (that is, the transaction request is a legal and normal request), the transaction processing node can process the target transaction ; when the transaction processing node determines that the transaction request does not meet a predefined condition prescribed in the verification rules (i.e., the transaction request may have problems such as non-compliant data format, illegal transaction request, etc.), the transaction processing node may not process the target transaction and return a warning to the user that the transaction request processing has failed, causing the user to restart a transaction request to the transaction processing node according to the warning .
[051] After the transaction processing node completes processing the transaction request using the transaction template, the transaction processing node can obtain corresponding transaction information. The transaction information here can be transaction results obtained after
Petition 870190066689, of 7/15/2019, p. 26/62
18/39 the transaction processing node processes the transaction, the transaction records to show the entire transaction processing process or transaction data included in the transaction request. The transaction processing node can subsequently write the transaction information to a blockchain. In this way, the user can later search for the transaction information on the blockchain and then perform operations such as data verification on the transaction information.
[052] In the modalities of this application, transaction models pre-stored in the transaction processing node can be directed to a variety of transactions, and in exemplary applications, transactions involving blockchain can be divided mainly into the following four types:
I. The tracking transactions, which record in detail a designated data transfer path, allowing a user to determine the designated data holder through the designated data transfer path, registered on a blockchain, that is, tracking to the origin of the data designated data.
II. Authentication transactions, which use the immutability of data stored in a blockchain and store designated data in the blockchain for later verification of the designated data or for verification of other data through the designated data.
Ill Contract-based smart transactions, which are specific transactions implemented using smart contracts in current technologies, such as regularly returning profits from finance management products to users by running a smart contract on a blockchain.
IV. Exchange Transactions, which carry out mutual transactions between users through a blockchain and record details of the transaction in the process of
Petition 870190066689, of 7/15/2019, p. 27/62
19/39 blockchain transaction.
[053] With respect to the four types of transactions described above, the transaction models capable of processing these four types of transactions are pre-stored in the transaction processing node in the modalities of this order. Therefore, after the transaction processing node receives transaction requests for these four types of transactions, the transaction processing node can load the four types of pre-stored transaction templates to process target transactions included in the four types of transaction requests. transaction, where the four types of transaction requests can be a tracking model, an authentication model, a contract model and an exchange model, respectively.
[054] To further describe the transaction processing process in the modalities of this order, the transaction processing processes for these four types of transaction requests will be described in detail below.
[055] When a transaction processing node receives a tracking data request sent by a user, the transaction processing node can determine, according to a tracking transaction identifier included in the tracking data request, the type tracking transaction number corresponding to the tracking transaction identifier, and then the transaction processing node can determine and load, according to the type of tracking transaction, a tracking template corresponding to the tracking transaction type of the tracking templates. pre-stored transaction. Then, by activating the tracking model, the transaction processing node processes a tracking transaction included in the tracking data request.
[056] In the process in which the transaction processing node processes the tracking transaction through the tracking model, the
Petition 870190066689, of 7/15/2019, p. 28/62
20/39 transaction processing can determine a tracking transaction processing rule corresponding to the tracking transaction type and execute the tracking transaction processing rule to obtain, through analysis, tracking data, an address of the tracking data recipient and a tracking data sender address included in the tracking data request. Subsequently, the transaction processing node can still send the tracking data to the tracking data recipient and generate corresponding tracking data transfer information. The transaction processing node then writes the transfer information to a blockchain, allowing the user to subsequently determine a transfer path of the tracking data using the transfer information stored on the blockchain.
[057] With respect to authentication transactions, when a transaction processing node receives an authentication data request sent by a user, the transaction processing node can determine the type of authentication transaction corresponding to the authentication data request and load an authentication template corresponding to the type of authentication transaction from the pre-stored transaction templates. The transaction processing node can determine an authentication transaction processing rule corresponding to the type of authentication transaction, obtaining, through analysis, through the authentication transaction processing rule, authentication data to be written to a blockchain as required by the user of the authentication data request and then write the authentication data to the blockchain.
[058] In the embodiments of the present invention, the transaction processing node can also execute transactions through an intelligent contract
Petition 870190066689, of 7/15/2019, p. 29/62
21/39 stored in the blockchain, namely, a contract model (i.e., a transaction model) corresponding to a transaction to be executed through a smart contract can be pre-stored in the transaction processing node. Then, when the transaction processing node receives a contract data request sent by a user, the transaction processing node can determine the contract transaction type corresponding to the contract data request and determine, according to the type contract transaction type, a contract template corresponding to the contract transaction type of the pre-stored transaction templates. The blockchain can further determine a contract transaction processing rule that matches the transaction type of the model contract contract and analyze, by executing the contract transaction processing rule, to obtain a contract address and transaction parameters included in the contract data request, where the contract address is the storage address of the smart contract on the blockchain. Subsequently, the transaction processing node can search for the smart contract on the blockchain at the contract address and then transmit the determined transaction parameters to the smart contract address, causing the smart contract to automatically execute the transaction parameters and resume the corresponding transaction results (that is, the transaction information) for the transaction processing node. After the transaction processing node receives the transaction results resumed by the smart contract, the transaction processing node can display the transaction results to the user and, at the same time, save the transaction results on the blockchain for later operations by how to perform data verification in the transaction results.
[059] With respect to exchange transactions, when a transaction processing node receives a transaction request sent by a user, the
Petition 870190066689, of 7/15/2019, p. 30/62
22/39 transaction processing can determine an exchange model capable of processing the transaction request from the pre-stored transaction models and process an exchange transaction included in the transaction request by loading the exchange model, where the processing node transaction can first determine, according to the type of exchange transaction determined, an exchange transaction processing rule that corresponds to the exchange transaction type of the exchange model. Through the exchange transaction processing rule, the transaction processing node obtains information involved in the transaction request through analysis, such as the transaction initiator, the transaction recipient, the transaction amount, etc., obtains the subtraction a corresponding transaction amount from a transaction initiator account by executing the exchange transaction processing rule and then transfers that transaction amount to transaction processing in a transaction recipient account. In this process, the transaction processing node can obtain transaction details for that transaction (that is, the transaction information). In order for the user to view the transaction details on the blockchain in a subsequent process and for a transaction certificate of the transaction details to be provided to the user in a subsequent process, the transaction processing node can write the transaction details to the blockchain.
[060] In the embodiments of the present invention, the transaction processing node can also support the transaction processing of other transactions, and a user only needs to load a transaction model of a desired transaction on the transaction processing node to obtain processing of the transaction by the transaction processing node.
[061] It can be seen from the methods described above that the transaction templates for processing multiple target transactions are pre-stored on a transaction processing node instead of a blockchain. So when
Petition 870190066689, of 7/15/2019, p. 31/62
23/39 a transaction is updated, a user only needs to perform corresponding updates on the transaction templates stored in the transaction processing node to make the transaction templates capable of supporting the updated transaction. There is no need to develop transaction models again to adapt to the updated transaction, and the transaction maintenance cost will be greatly reduced compared to current technologies in which a user can only develop smart contracts again to make smart contracts support the transaction processing of an updated transaction.
[062] In the modalities of the present invention, the user can precompile all transaction models and insert the transaction models in the transaction processing node. Correspondingly, after the transaction processing node receives the transaction templates entered by the user, the transaction processing node can store the transaction templates in the transaction processing node. In a subsequent process, the transaction processing node can process incoming transaction requests by loading these transaction templates.
[063] In the modalities of the present invention, the user can package and release all transaction models on a transaction platform, causing other users to need a transaction model installation package to download the installation package of the corresponding transaction model from the transaction platform and to store the transaction model installation package on a local transaction processing node. After the local transaction processing node loads the transaction model installation package, the transaction processing node can process transactions corresponding to the transaction model, as shown in Figure 2.
[064] Figure 2 is a schematic diagram of users who release
Petition 870190066689, of 7/15/2019, p. 32/62
24/39 transaction model installation packages on a transaction platform in accordance with some of the modalities of this application.
[065] In Figure 2, user A can compile transaction models using a compiled language and package the transaction models, respectively, to upload to a transaction platform. After the transaction platform receives the transaction model installation packages loaded by user A, the transaction platform can release the transaction model installation packages for other users to download and use. Transaction template installation packages can also be uploaded by other users, and users can share their compiled transaction template installation packages on the transaction platform respectively for other users to use.
[066] It should be noted that, in exemplary applications, smart contracts are usually compiled and written on a blockchain by users themselves. If a user compiles and writes a malicious smart contract on a blockchain, the smart contract could result in inconvenience and losses in processing transactions based on the smart contract by other users.
[067] To avoid the situation described above, in the modalities of the present invention, the transaction platform can check the transaction model installation packages sent by users. When a transaction model installation package sent by a user is found to contain malicious code, the transaction model installation package will not be released, thus providing a good environment for downloading transaction model installation packages for users .
[068] The modalities of the present invention further provide a method of processing transactions. Figure 3 is a schematic diagram of a
Petition 870190066689, of 7/15/2019, p. 33/62
25/39 method of processing transactions according to some embodiments of the present invention.
[069] A transaction processing node receives a transaction request and determines a transaction type of a target transaction included in the transaction request; loads, according to the type of transaction, a transaction model corresponding to the type of transaction; further processes the target transaction according to the transaction model and records transaction information obtained from processing in a target block on a blockchain; and when recording the transaction information obtained in the target block, it determines and stores a change of state value of the target block, the change of state value being used to verify that the transaction information registered in the target block is consistent with the information of transactions recorded in other blocks on the blockchain.
[070] In addition, determining and storing a change in state value of the target block comprises:
after recording the transaction information obtained in the target block, calculate a check value of the target block; determine the check value as the target block state change value; and store the state change value on the blockchain.
[071] That is, when the transaction information is recorded in different blocks, the change values of the blocks can be determined through computation. In this way, the change values of different blocks are stored sequentially in a tree structure, such as a Merkle tree, and then if the data stored in different blocks on the blockchain are consistent, they can be determined using a hash value of a root node of the Merkle tree.
[072] The blockchain according to the modalities of the present invention can be a blockchain such as Bitcoin blockchain, Ethereum blockchain,
Petition 870190066689, of 7/15/2019, p. 34/62
26/39 Litecoin blockchain, etc.
[073] It should also be noted that, after the transaction processing node completes processing the transaction desired by the user (that is, the target transaction included in a transaction request sent by the user) through the determined transaction model, the node transaction processing can download the loaded transaction template, thereby saving the memory space of the transaction processing node. Alternatively, after the transaction processing node has completed processing the target transaction, the transaction processing node can also suspend the transaction model and reactivate the transaction model, after a transaction request corresponding to the transaction model is received later to process the transaction request.
[074] In the embodiments of the present invention, all transaction models for processing multiple target transactions are pre-stored on a transaction processing node, rather than stored on a blockchain. Therefore, when a transaction is updated, a user only needs to perform corresponding updates on the transaction templates stored in the transaction processing node to make the transaction templates capable of supporting the updated transaction. There is no need to develop transaction models again to adapt to the updated transaction, and the cost of maintaining transactions will be greatly reduced compared to current technologies in which a user can only re-develop smart contracts to make smart contracts again support the processing of transactions for an updated transaction. However, the problem that transaction processing methods are not flexibly adaptable to transaction updates is resolved, and the flexibility of blockchain transaction processing is greatly improved.
Petition 870190066689, of 7/15/2019, p. 35/62
27/39 [075] In addition, in a process where the transaction processing node performs transaction processing using pre-stored transaction models, all system resources required to process a target transaction using a model transactions are allocated by the transaction processing node itself and the transaction processing node can use all the system resources of the transaction processing node to process the target transaction, which effectively avoids the problem in current technologies that the systems called by a virtual machine in a smart contract execution process are insufficient, greatly improve the efficiency of processing blockchain transactions and facilitate a user's transaction processing.
[076] In the modalities of the present invention, in a transaction processing process, a user can enter a transaction request corresponding to the transaction processing node. After the transaction processing node receives the transaction request, the transaction processing node determines a transaction type of a target transaction included in the transaction request, loads a transaction template corresponding to the transaction type, and processes the target transaction through the transaction model, where the transaction processing node can be a terminal capable of processing blockchain transactions, a server to process blockchain transactions, or a client or application to process blockchain transactions.

[089] In the modalities of the present invention, after the transaction processing node receives the transaction request sent by the user, the transaction processing node can load, according to the transaction type of the target transaction included in the transaction request, a transaction model corresponding to the type of transaction, and process the target transaction using the transaction model.

There is no need to re-develop transaction models to adapt to the updated transaction, and the cost of maintaining the transaction will be greatly reduced compared to current technologies, in which a user can only re-develop smart contracts to make the contracts smart devices developed to support transaction processing for an updated transaction. However, the problem that transaction processing methods are not flexibly adaptable to transaction updates is resolved, and the flexibility of transaction processing on the blockchain is greatly improved.

[091] Based on the same concept, the modalities of this application also provide a transaction processing device, as shown in Figure 5.
[092] Figure 5 is a schematic diagram of a transaction processing apparatus according to some modalities of the present patent application, comprising:
a receiving module 501 configured to receive a transaction request and determine a transaction type for a target transaction included in the transaction request;

[094] In the 1990s, an improvement to a technology can obviously be differentiated into a hardware improvement (for example, an improvement to a circuit structure, such as a diode, a transistor, a switch, etc.) or an improvement software (an improvement to a method flow). With technological development, however, many current improvements in method flows can be seen as direct improvements in hardware circuit structures. Designers almost always obtain a corresponding hardware circuit structure by programming an improved method flow in a hardware circuit. Therefore, it cannot be concluded that an improvement in a method flow cannot be accomplished with a hardware module. For example, the Programmable Logic Device (PLD) (for example, (the FPGA) Field Programmable Gate Array) is an integrated circuit in which the logic functions of the integrated circuit are determined by a user through device programming. A designer can program on his own to "integrate" a digital system into a PLD part, without having to ask a chip maker to design and manufacture a dedicated IC chip. Currently, moreover, this type of programming has been mainly implemented through “logical compiler” software, instead of manually manufacturing IC chips. The logic compiler software is similar to a software compiler used for developing and recording programs, while a specific programming language must be used to write source code before compiling, which is called the Description Language of
Petition 870190066689, of 7/15/2019, p. 42/62
34/39
Hardware (HDL). There is not only one, but many types of HDL, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL ( hardware description language Java), Lava, Lola, MyHDL, PALASM, RHDL (Ruby hardware description language), etc. The most common currently used includes VHDL (High Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also know that it would be easy to obtain a hardware circuit to implement a logical method flow using the HDLs above to perform some logic programming in the method flow and to program the method flow in a CI.
[095] A controller can be implemented in any appropriate manner. For example, a controller may be, for example, in the form of a microprocessor or processor, as well as in a computer-readable medium that stores computer-readable program codes (for example, software or firmware) capable of being executed by ( micro) processor, a logic port, a switch, an Application Specific Integrated Circuit (ASIC), a programmable logic controller and a built-in microcontroller. Controller examples include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20 and Silicone Laboratories C8051F320. A memory controller can also be implemented as part of a memory control logic. Those skilled in the art should also be aware that, in addition, a controller is implemented in a pure form of computer-readable program codes, it is possible to perform logical programming in steps of a method to allow a controller to implement the same functions in the in the form of a logic gate, a switch, an ASIC, a programmable logic controller, a microcontroller
Petition 870190066689, of 7/15/2019, p. 43/62
35/39 built-in, etc. Therefore, such a controller can be considered as a piece of hardware, while devices comprised in the controller and configured to achieve various functions can also be considered as a structure within the hardware part. Alternatively, devices configured to achieve various functions can even be considered both as software modules to implement a method and a structure within a piece of hardware.
