Illustratively, according to an embodiment of the present invention, the user information further includes user feature information, where the user feature information includes one or more of the following information: user type, user attribution, user consumption type; after the step of acquiring the user information, further comprising:

By the arrangement, the hash storage of the digital currency of the user is realized, and the transaction processing performance of the digital currency system in busy hours is effectively improved.

Further, according to an embodiment of the present invention, according to transaction level information and digital currency balances, a storage line of digital currency corresponding to each transaction level is determined, and according to the storage line, the digital currency balances are respectively stored to the corresponding transaction levels, including:

Specifically, after different transaction levels and level amounts are determined according to historical transaction information of a user, through the setting, a level queue corresponding to the transaction level information is generated according to the transaction number proportion and the level amounts corresponding to each transaction level, and the steps can be realized through machine learning, so that the transaction level with the highest transaction number proportion ratio is positioned above the level queue in the finally generated level queue; and meanwhile, each transaction level is respectively segmented, so that each segmented block can store digital currency which does not exceed the level line of the corresponding transaction level, and the arrangement is beneficial to hashing more storage lines in the transaction level with the highest transaction frequency proportion ratio, so that the transaction habit of a user is facilitated, and the transaction efficiency is improved in the transaction process, particularly in the high-concurrency transaction process.

Preferably, according to an embodiment of the present invention, according to a digital currency balance and a gradient hierarchy queue including a plurality of cut segments, a storage unit of digital currency corresponding to each consumption hierarchy is determined, and according to the storage unit, the digital currency balance is stored to a corresponding transaction hierarchy, respectively, including:

Through the arrangement, after each transaction level in the level queue is diced and divided, each diced block in the level queue can be numbered in sequence according to the level limit of the transaction level corresponding to each diced block and the position of each diced block in the level queue, so as to obtain the block number of each diced block; so that the user's digital money balance is stored in the corresponding cut block according to the order of the block numbers.

Illustratively, according to an embodiment of the present invention, the numbering each segment in the hierarchical queue sequentially includes:

Specifically, because the number of the cut blocks relates to the corresponding storage limit of each transaction level, when the cut blocks in the level queue are numbered, the positions of the transaction levels corresponding to the cut blocks in the level queue (the transaction level with high proportion of transaction times is positioned above the level queue) are considered, and the corresponding relation between the cut blocks of the current level and the cut blocks of the next level is combined, so that the balance of digital currency of a user can be scattered to cover more transaction levels as much as possible, more stored digital currency in the common transaction levels is ensured, the transaction processing performance is effectively improved, and the transaction efficiency is improved.

Step S102, determining target digital currency corresponding to the user transaction request according to the user transaction request and the transaction hierarchy information; the transaction hierarchy information is generated according to historical transaction information and digital currency balances of users, and comprises hierarchy numbers of transaction hierarchies, hierarchy amounts corresponding to each transaction hierarchy and transaction times proportions.

Specifically, according to an embodiment of the present invention, determining, according to the user transaction request and the transaction hierarchy information, the target digital currency corresponding to the user transaction request includes:

Since the historical transaction information includes transaction amounts and/or transaction types for each historical transaction, the transaction level determined from the historical transaction information also indicates different transaction amounts and/or transaction types. After receiving the transaction request of the user, a candidate transaction hierarchy can be determined from a plurality of transaction hierarchies according to the transaction amount or the transaction type indicated in the transaction request of the user, then whether the currently stored digital currency in the candidate transaction hierarchy can complete the transaction amount indicated by the transaction request of the user is judged, if so, the candidate transaction hierarchy is determined to be a target transaction hierarchy, and the digital currency corresponding to the currently stored amount in the target transaction hierarchy is determined to be the target digital currency. If not, the next transaction level can be determined as the candidate transaction level, and then the judgment is carried out until the target transaction level is determined. It should be noted that the number of the candidate transaction levels and the target transaction level may be one or more, that is, the target transaction currency may be determined by using digital currencies in the current memory line of the one or more transaction levels.

Step S103, responding to the user transaction request according to the target digital currency.

Further, according to the embodiment of the present invention, the current memory value unit corresponding to each transaction level is also monitored to prevent the situation that the actual balance of the user is insufficient, but the memory value of the digital currency of a certain level is insufficient, resulting in transaction failure. For example, a hierarchy queue storage amount middle table may be provided for monitoring the current storage amount corresponding to each transaction hierarchy.

According to the technical scheme of the embodiment of the invention, the method and the device adopt the steps of receiving the user transaction request; determining a target digital currency corresponding to the user transaction request according to the user transaction request and the transaction hierarchy information; the transaction hierarchy information is generated according to historical transaction information and digital currency balance of a user, and comprises hierarchy numbers of transaction hierarchies, hierarchy amount corresponding to each transaction hierarchy and transaction frequency proportion; according to the target digital currency, the technical means of responding to the user transaction request is overcome, and the technical effects that in the existing digital currency transaction method, as the digital currencies are basically stored together, when digital currency transaction is carried out, especially in a high concurrency scene, the resource conflict of a digital currency system is frequently existed, so that the transaction overtime is caused, the performance and stability of the digital currency system are reduced, the technical problem that the transaction processing performance of the system is lower is solved, further, the digital currency hash of the user can be stored to different transaction levels, especially in the high concurrency scene, the resource conflict of the digital currency system when the user carries out the digital currency transaction is effectively avoided, the transaction efficiency is improved, the performance and stability of the digital currency system are improved, and the transaction processing performance of the system is improved are achieved.

FIG. 2a is a schematic diagram of the main flow of a method for trading digital money according to a second embodiment of the present invention; as shown in fig. 2a, the method for trading digital currency according to the embodiment of the present invention mainly includes:

step S201, obtaining user information, wherein the user information comprises historical transaction information and digital currency balance of a user; and determining transaction level information corresponding to the user according to the historical transaction information.

According to an embodiment of the present invention, a plurality of levels are determined according to a transaction amount corresponding to each transaction in the historical transaction information of the user, for example, for a plurality of historical transactions between 0 and 50 yuan, a 50 yuan transaction level may be determined, where 50 yuan is the level amount of the transaction level. Finally, 8 transaction levels above 50, 100, 150, 200, 500, 1000, 5000, and 5000 can be determined (by way of example only).

On the other hand, transaction levels can be further divided according to transaction types, for example, transaction amounts for payment types such as daily diet, travel and the like are often within 50 yuan, so that transaction levels corresponding to 50 yuan can be determined, for example, transaction amounts for decoration types are often above 5000, transaction levels above 5000 can be determined, and the like, and finally a plurality of transaction level information corresponding to users are determined.

According to a specific implementation of the embodiment of the invention, when determining a database stored corresponding to the digital currency balance of the user according to the user type, the user attribution and the user consumption type: whether the user is an individual user or an enterprise user can be judged according to the user type; if the user is an enterprise user, determining a database corresponding to and storing digital currency of the enterprise user according to the attribution of the user; namely, the digital currencies of users in different attribution areas are stored in databases corresponding to different cities, so that the transaction efficiency is improved. If the user is a personal user, the digital currency of different transaction types can be stored in different databases according to the transaction types of the user, so that when the user performs the digital currency transaction, the target digital currency can be determined from the different databases according to the type to be transacted for the transaction. According to another specific implementation of the embodiment of the invention, the database stored corresponding to the digital currency balance of the user can be determined directly according to any one or any two of the user type, the user attribution and the user transaction type. By the arrangement, the hash storage of the digital currency of the user is realized, and the transaction processing performance of the digital currency system in busy hours is effectively improved.

Step S202, generating a hierarchy queue corresponding to the transaction hierarchy information according to the transaction number proportion and the hierarchy amount corresponding to each transaction hierarchy in the transaction hierarchy information.

Specifically, according to the transaction number proportion and the hierarchy limit corresponding to each transaction hierarchy, a hierarchy queue corresponding to transaction hierarchy information is generated, and the steps can be realized through machine learning, so that in the finally generated hierarchy queue, the transaction hierarchy with the highest transaction number proportion is located above the hierarchy queue, and transaction habits of users are facilitated, and digital currency of the corresponding storage limit is hashed according to the position of each transaction hierarchy in the hierarchy queue.

According to an embodiment of the present invention, for example, the consumption behavior of the user under 50 yuan (corresponding to the transaction level of 50 yuan) accounts for 40% and the consumption behavior under 50 to 100 yuan (corresponding to the transaction level of 100 yuan) accounts for 10% and 100 to 200 accounts for 10% (corresponding to the transaction level of 200 yuan) in a period of time, then three transaction levels are total in the transaction levels, the 50 yuan level is located at the top, the 100 yuan level is located at the middle, and the 200 yuan level is located at the bottom. This is because the proportion of the number of transactions at the 50-ary level is highest, and the proportion of the number of transactions at the 100-ary level and the 200-ary level is consistent, but the level amount (100-ary) at the 100-ary level is smaller than the level amount (200-ary) at the 200-ary level, so that the 100-ary level is placed above the 200-ary level for subsequent hash storage.

Step S203, dividing each transaction level of the level queue according to the level amount to obtain a level queue containing a plurality of divided blocks; the storage limit of the digital currency corresponding to the segmentation block does not exceed the level limit of the corresponding transaction level.

Through the arrangement, each transaction level is respectively segmented, so that each segmented block can store digital currency which does not exceed the level line of the corresponding transaction level, and the arrangement is beneficial to hashing more storage lines in the transaction level with the highest transaction frequency proportion, so that the transaction habit of a user is facilitated, and the transaction efficiency is improved in the transaction process, particularly in the high-concurrency transaction process.

Step S204, according to the level limit of the transaction level corresponding to each segmentation block in the level queue and the position of each segmentation block in the level queue, numbering each segmentation block in the level queue in turn to obtain the block number of each segmentation block.

Step S205, according to the sequence of the block numbers, the digital currency balances are sequentially stored in a plurality of cutting blocks until the digital currency balances are stored.

Specifically, the cut blocks are numbered longitudinally in the order of the plurality of transaction levels in the level queue from top to bottom. The purpose of this is to provide a narrow hierarchical distribution of digital currency when the balance of the user's digital currency is small, and to prevent the user from being able to quickly locate the available digital currency. Fig. 2b shows a schematic structure of a hierarchical queue containing a plurality of numbered sliced chunks, according to an embodiment of the present invention, as shown in fig. 2b (only part of the numbering is shown), the sliced chunks are numbered longitudinally in the order of the transaction levels in the hierarchical queue from top to bottom.

Firstly, determining the uppermost transaction level of a level queue as the current transaction level, then marking a first segmentation block in the current transaction level as a number 1, then according to the corresponding relation between the segmentation block with the number 1 of the first level and the segmentation block with the next level (the second level at this time), knowing that a straight line corresponding to the right side of the segmentation block 1 is positioned at the left side of a straight line corresponding to the right side of the segmentation block with the next level, numbering the segmentation block with the first level, marking the number 2, then knowing that a straight line corresponding to the right side of the segmentation block 2 is overlapped with the straight line corresponding to the right side of the segmentation block with the next level, marking the segmentation block with the second level as a number 3, and regarding the segmentation block 3 with the right side of the segmentation block with the second level, knowing that the straight line corresponding to the right side of the segmentation block with the next level is positioned at the left side of the corresponding straight line of the segmentation block with the next level, and returning to the unnumbered segmentation block with the first level at this time, marking the segmentation block with the number 4. That is, when the straight line corresponding to the right side of the current level dividing block does not coincide with the straight line corresponding to the right side of the unnumbered dividing block of the next level, or the former corresponding straight line is positioned on the right side of the latter corresponding straight line, the arrangement of the transaction levels in the level queue from top to bottom in the current round is ended, the first level of the level queue is returned again, and the numbering of the second round is started.

In a preferred embodiment, the hierarchical queue may be further partitioned directly according to the consumption frequency determined by the historical transaction information and the actual digital currency balance of the user, that is, the hierarchical queue may be partitioned into blocks after the actual digital currency balance of the user is determined. For example, according to the historical transaction information of the user, transactions with a 10-by-15 consumption frequency are all under 100 yuan, transactions with a 4-by-15 consumption frequency are all under 1000 yuan, and transactions with a 1-by-15 consumption frequency are all under 5000 yuan. Based on this, 3 transaction levels, a 100-ary transaction level, a 1000-ary transaction level, and a 5000-ary transaction level may be determined. If the actual digital currency balance of the user is ten thousand yuan. According to the consumption frequency proportion, 10 segmentation blocks can be divided from a 100-element transaction hierarchy, and 100-element digital currency is stored in each segmentation block; dividing 4 segmentation blocks in a 1000-element transaction hierarchy, and storing 1000-element digital currency in each segmentation block; the 5000-element transaction hierarchy is divided into 1 segmentation block, and 5000-element digital currency is stored in each segmentation block.

According to another embodiment of the present invention, if the transaction type is billing, at this time, a billing amount may be determined, a corresponding transaction level is determined according to the billing amount, and digital currency corresponding to the billing amount is stored in a cut block in the corresponding transaction level. Further, if there are partial blocks in the corresponding transaction level, but the empty amount of the partial block is smaller than the account amount, the account amount is hashed again and stored in different partial blocks of the corresponding transaction level. Preferably, if the segmentation block of the corresponding transaction hierarchy is full of digital currency, the digital currency corresponding to the account entry amount may be stored in the transaction hierarchy with larger hierarchy amount.

According to the embodiment of the invention, the updating periods can be set, each updating period is satisfied, the transaction level updating information is determined according to the historical transaction information of the user in the last updating period, and then the level queue and the storage limit corresponding to each transaction level in the level queue are updated, so that the user experience is improved.

Step S206, receiving a user transaction request.

Step S207, determining candidate transaction levels from the transaction level information according to the transaction amount or the transaction type indicated in the user transaction request.

Since the historical transaction information includes transaction amounts and/or transaction types for each historical transaction, the transaction level determined from the historical transaction information also indicates different transaction amounts and/or transaction types. After receiving the transaction request of the user, the candidate transaction levels can be determined from a plurality of transaction levels according to the transaction amount or the transaction type indicated in the transaction request of the user, wherein the number of the candidate transaction levels is generally one, and when the memory amount is less, the candidate transaction levels can also be a plurality of candidate transaction levels.

Step S208, judging whether the corresponding current memory line in the candidate transaction hierarchy is greater than or equal to the transaction line. If not, executing step S209; if yes, go to step S210; .

Step S209, updating the candidate transaction level according to the corresponding level limit and the current memory limit. And then goes to step S208.

Step S210, determining the candidate transaction level as a target transaction level, and determining the digital currency corresponding to the current memory line in the target transaction level as the target digital currency.

Through the setting, whether the currently stored digital currency in the candidate transaction hierarchy can complete the transaction amount indicated by the user transaction request is judged, if so, the candidate transaction hierarchy is determined to be the target transaction hierarchy, and the digital currency corresponding to the currently stored amount in the target transaction hierarchy is determined to be the target digital currency. If not, the next transaction level may be determined to be the candidate transaction level (i.e., the candidate transaction level is updated), and then the determination is performed until the target transaction level is determined. It should be noted that the number of target transaction levels may be one or more, i.e. the target transaction currency may be determined from the digital currency in the current memory line of the one or more transaction levels.

Step S211, responding to the user transaction request according to the target digital currency.

Further, according to the embodiment of the present invention, a middle table of the level queue storage line may be further configured to monitor the current storage line corresponding to each transaction level, so as to prevent the situation that the actual balance of the user is insufficient, but the storage amount of the digital currency of a certain level is insufficient, so that the transaction fails.
