Step S230, determining the total expected transfer value and the total expected transfer amount of the target type resource of each resource transferor according to the numerical value of the demand amount of the target type resource of each resource transferor and the preset standard value parameter of the target type resource.
In order to realize the transfer under the fair condition, the price which minimizes the loss of all the persons must be obtained by compromising the price expectation matrix of each resource transfer participant, that is, the transfer value of each type of resource in the current transfer needs to be determined, the comprehensive loss of each resource transfer participant is minimized as much as possible, and the transfer value is recorded as a transfer reference value parameter in the middle of the embodiment; in an embodiment, the loss of each resource transfer participant may be represented by a transfer reference value parameter, a required amount of each resource type by each resource transfer participant, and a preset standard value parameter of each resource type, and further, according to a condition for minimizing the loss of each resource transfer participant, the transfer reference value parameter of each resource type may be determined according to the required amount of each resource type by each resource transfer participant and the preset standard value parameter of each resource type.

In one embodiment, the expected total value of each resource transfer party for the target type resource represents the total value corresponding to the numerical value of the demand of each resource transfer participant for the target type resource (including the value corresponding to the transferred-in and transferred-out demand); the total number of desired transfers of each resource transfer party to the target type resource represents the sum of the values of the demand amounts of each resource transfer participant for the target type resource.
Further, in an embodiment, determining the total value and the total number of expected transfers of each resource transferor to the target type resource according to the value of the demand amount of each resource transferor to the target type resource and a preset standard value parameter of the target type resource includes: determining the product of the numerical value of the demand of the resource transferrer for the target type resource and a preset standard value parameter of the target type resource as the expected transfer value of the resource transferrer for the target type resource, and determining the expected transfer total value of each resource transferrer for the target type resource according to the expected transfer value of each resource transferrer for the target type resource; and determining the total expected transfer amount of each resource transferor to the target type resource according to the sum of the numerical values of the demand amounts of each resource transferor to the target type resource.

Step S240, determining the ratio of the total value expected to be transferred to the total amount expected to be transferred as a transfer reference value parameter of the target type resource, and returning to the step of randomly selecting one of the types of resources as the target type resource without repeating until the transfer reference value parameter of each type of resource is determined.
And determining a total expected transfer value parameter corresponding to each type of resource according to the total expected transfer value corresponding to each type of resource in the current resource transfer and the total expected transfer amount corresponding to each type of resource.
In a specific embodiment, assuming that the mth resource in each type of resource is a target type resource, a transfer reference value parameter P of the target type resource is formulated m The determination method comprises the following steps:
wherein m represents the number of types of resources, n represents the number of resource transfer participants, a im Representing the demand, V, of the m-th type of resource by the ith resource transfer participant m And the preset standard value parameter represents the m-th type of resource.
And step S250, performing resource transfer according to the transfer reference value parameters of the resources of the types and the demand of the resource transferors for the resources of the types.
The step S240 is executed to determine the transfer reference value parameters of each type of resource, and corresponding resource transfer can be performed in combination with the demand of each resource transfer participant for each type of resource.
In one embodiment, as shown in fig. 3, the resource transfer according to the transfer reference value parameter of each type of resource and the required amount of each resource transferor for each type of resource includes steps S310 to S330.
Step S310, obtaining a reference value parameter of the preset reference type resource.
The preset reference type resource may be one of the types of resources, or may not belong to one of the types of resources.
In one embodiment, the preset reference type resource belongs to each type of resource, and the obtaining of the reference value parameter of the preset reference type resource includes: taking the transfer reference value parameter of the preset reference type resource as a reference value parameter of the preset reference type resource; in another embodiment, the preset reference type resource does not belong to each type of resource, and obtaining the reference value parameter of the preset reference type resource includes: and acquiring a preset standard value parameter of the preset reference type resource and determining the preset standard value parameter as a reference value parameter of the preset reference type resource.
Step S320, according to the transfer reference value parameter of each type of resource and the reference value parameter of the preset reference type of resource, converting the demand of each type of resource into an equivalent demand of each resource transfer party for each type of resource, which is expressed by the preset reference type of resource.
After the transfer reference value parameters of the resources of each type are determined, the requirements of the resource transfer participants on the resources of the type can be expressed by the preset reference type resources according to the transfer reference value parameters of the resources of each type and the reference value parameters of the preset reference type resources. In this embodiment, the amount of demand of each resource transfer participant for the type resource is converted into the equivalent amount of demand of the preset reference type resource, and the equivalent amount of demand is recorded.
Step S330, the equivalent demand of each type of resource is transferred according to each resource transferor expressed by the preset reference type of resource.
After obtaining the equivalent demand quantity of each type of resource by each resource transferrer represented by the preset reference type of resource, determining which specific resource transferors need to perform resource transfer between each other according to the equivalent demand quantity. In one embodiment, a resource transfer scheme is determined according to the equivalent demand of each resource transferrer expressed by preset reference type resources on each type of resources, and resource transfer is performed according to the resource transfer scheme.
In an embodiment, the resource transfer scheme includes a specific scheme of how to transfer the type resource among the resource transfer participants, and specifically may include a transfer object that the resource transfer participant a participates in the transfer, a type of the type resource to be transferred, and a quantity of the type resource to be transferred; in one particular embodiment, for example: for the type resource a, the resource transfer participant a needs to transfer 2 type resources a to the resource transfer participant b (which may also be expressed as that the resource transfer participant b needs to receive 2 type resource a transfers from the resource transfer participant a), and the resource transfer participant c needs to transfer 1 type resource a to the resource transfer participant b (which may also be expressed as that the resource transfer participant b needs to receive 2 type resource a transfers from the resource transfer participant c).
In one embodiment, the resource transfer of the equivalent demand of each type of resource according to each resource transferor represented by a preset reference type of resource includes: and when the equivalent demand of each resource transfer party for each type of resource is determined to meet the preset condition, transferring the resource according to the equivalent demand.
Further, in an embodiment, when the asset transferring-in and transferring-out of each resource transferring party is determined to be equivalent to the asset transferred out according to the equivalent demand of each resource transferring party for each type of resource, and the total transferring-in quantity and the total transferring-out quantity of each type of resource are the same, it is determined that the preset condition is met. The equivalence of the transferred-in assets and the transferred-out assets of each resource transfer participant means that the assets of the resource transfer participants are not lost after the resources are transferred, and the fact that the transferred-in quantity and the transferred-out quantity of the type resources are the same means that the type resources in the resource transfer are kept balanced.
The data processing method comprises the steps of respectively acquiring the demand of each resource transferrer for each type of resource and the preset standard value parameter of each type of resource, determining the total expected transfer value of each type of resource and the total expected transfer quantity of each type of resource according to the demand value of each resource transferrer for one type of resource and the preset standard value parameter of each type of resource, and determining the ratio of the total expected transfer value corresponding to each type of resource to the total expected transfer quantity as the transfer reference value parameter of each type of resource; the transfer reference value parameters of various types of resources can be determined by adopting the method; and further, completing resource transfer according to the transfer reference value parameters of the resources of various types and the various demands of the resource transfer participants. According to the method, the transfer reference value parameters of the resources of each type can be determined according to the acquired demand of each resource transfer party on the resources of each type and the preset standard value parameters of the resources of each type, the resources are transferred according to the transfer reference value parameters of the resources of each type determined by the method, a third party does not need to manually determine a scheme for transferring the resources, and the risk of resource transfer can be reduced.
Further, in an embodiment, the resource transferring the equivalent demand of each type of resource according to each resource transferor represented by a preset reference type of resource includes: constructing an equivalent demand matrix of each resource transferrer for each type of resource according to the equivalent demand of each resource transferrer for each type of resource expressed by preset reference type resources; and carrying out resource transfer based on the equivalent demand matrix of each resource transferrer for each type of resource.
The equivalent demand matrix is a matrix which represents the demand of each resource transfer participant by a preset reference type resource; in one embodiment, a demand matrix of each resource transfer participant for each type of resource can be constructed when the demand of each resource transfer participant for each type of resource is obtained, and each value ratio of the transfer reference value parameter of each type of resource to the preset reference type of resource is determined according to the transfer reference value parameter of each type of resource and the reference value parameter of the preset reference type of resource; converting the demand matrix of each resource transfer participant for each type of resource into an equivalent demand matrix expressed by preset reference type resources according to each value ratio; fig. 4 is a schematic diagram of an equivalent requirement matrix in an embodiment, where a positive number represents that the requirement of the resource transfer participant is a value of a type resource expected to be transferred in, and a negative number represents that the requirement of the resource transfer participant is a value of a type resource expected to be transferred out.
In one embodiment, as shown in fig. 5, performing resource transfer based on the equivalent requirement matrix of each resource transferor for each type of resource includes steps S510 to S540.
Step S510, one of the resources of different types is randomly selected as the current transfer type resource without repeating.
In this embodiment, a transfer scheme is sequentially determined for each resource type, and the current transfer type resource refers to a type resource that needs to be determined to participate in the resource transfer scheme currently, and may be any one of various types of resources.
Step S520, traversing the equivalent demand of each resource transferrer in the equivalent demand matrix for the current transfer type resource, and sequentially determining the transfer object and the transfer amount of each resource transferrer corresponding to the current transfer type resource.
Step S520 is actually a scheme for determining how to transfer between the resource transfer participants for the current transfer type resource by searching the requirements (expressed by the number of the preset reference type resources) of the resource transfer participants for the current transfer type resource.
In a specific embodiment, taking the requirement of the resource transfer participant methylethyl-propyl for the current transfer type resource a as an example, the requirement of the resource transfer participant a is the type resource a equivalent to transfer into 2 preset reference type resources, the requirement of the resource transfer participant b is 0, the requirement of the resource transfer participant c is the type resource a equivalent to transfer out 4 preset reference type resources, and the requirement of the resource transfer participant D is the type resource a equivalent to transfer into 2 preset reference type resources; traversing the equivalent demand of each resource transfer participant on the type resource A, determining that the transfer object of the resource transfer participant A is C, the transfer quantity is the type resource A equivalent to the transferred 2 preset reference type resources, the transfer object of the resource transfer participant D is C, and the transfer quantity is the type resource A equivalent to the transferred 2 preset reference type resources.
Step S530, the step of randomly selecting one of the resources of each type as the current transfer type resource is returned without repeating until the transfer object and the transfer amount of each resource transfer party corresponding to each type of resource are determined.
After determining the transfer objects and the transfer numbers of the resource transfer participants corresponding to one type of resource, returning to reselect the current transfer type resource, and sequentially determining the transfer objects and the transfer numbers of the resource transfer participants corresponding to all other types of resources according to the methods of the step S510 and the step S520.
In step S540, the resource is transferred according to the transfer target and the transfer amount of each resource transfer party.
After the transfer objects and the transfer quantity of each resource transfer participant corresponding to all types of resources are determined, the transfer objects and the transfer quantity are summarized, the resource transfer scheme of the time can be obtained, and further the resource transfer can be carried out in each resource transfer participant according to the resource transfer scheme.
Further, in one embodiment shown in fig. 5, after each resource transfer participant converts each type of resource into an equivalent demand represented by the number of preset reference type resources, it can be determined whether a preset condition is met according to the equivalent demand, and in the equivalent demand, for any type of resource, the sum of the equivalent demand of each resource transfer participant is 0 (the number of transfer-in and transfer-out of each type of resource is equal); likewise, for any one resource transfer participant, the sum of the equivalent demand amounts for each type of resource is 0 (the value of the transferred-in resource and the transferred-out resource is equal for each resource transfer participant).
In one embodiment, the obtaining the required amount of each type of resource by the plurality of resource transferors and the preset standard value parameter of each type of resource includes: receiving resource transfer requests sent by nodes in each block chain; analyzing each resource transfer request, and determining a plurality of associated resource transferors, each type of resource, the demand of the resource transferors for each type of resource, and a preset standard value parameter of each type of resource.
In this embodiment, the data processing method is applied to a node server of a block chain, and is specifically applied to solving multi-currency transfer of multiple transfer participants in a cross-chain. Further, in one embodiment, the resource transfer across the chain may be implemented by notarization, relaying, hash locking, or distributed private key control techniques.
In one embodiment, a notarization technology is used to implement cross-chain money transfer for detailed description, a notarization node (a node having an identity of a blockchain in which each resource transfer participant is located and trusted by each resource transfer participant) receives resource transfer requests sent by nodes in each blockchain, and obtains associated resource transfer participants, related resources of various types, demand amounts of the resource transfers for the resources of various types, and preset standard value parameters of the resources of various types by analyzing the resource transfer requests.
When the nodes in the block chain corresponding to each resource transfer request pass corresponding identity verification, calling corresponding intelligent contracts, determining transfer reference value parameters of each type of resource according to the steps in the method, converting the demand of a resource transfer party for each type of resource into equivalent demand expressed by the quantity of the preset type of resource, constructing an equivalent demand matrix, traversing the equivalent demand of each type of resource in the equivalent demand matrix when the preset conditions are met according to the equivalent demand matrix, determining the transfer objects and the transfer quantity of each resource transfer participant, and initiating resource transfer in each block chain by a notarization node according to the transfer objects and the transfer quantity of each resource transfer participant corresponding to each type of resource; in another embodiment, when the preset condition is determined not to be met according to the equivalent requirement matrix, the resource transfer is determined to fail, and the failed information is returned to the nodes in each block chain sending the request. In other embodiments, resource transfers across chains may be implemented in other ways as well.
The block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The block chain (Blockchain), which is essentially a decentralized database, is a string of data blocks associated by using a cryptographic method, and each data block contains a batch of information transferred from the network, and is used for verifying the validity (anti-counterfeiting) of the information and generating the next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer.
Further, in one embodiment, the derivation process for determining the transfer reference value parameters for various digital currencies is described in detail, assuming that the resource transfer applies to the transfer of digital currencies, involving n resource transfer participants and m digital currencies.

The demand for type resources. For example
Denotes the first
A resource transfer participant wants to buy 2 resources of the first type if
Then represents the first
The resource transfer participant wants2 resources of the first type are to be sold.
Defining the matrix V as a price ratio matrix, for example, the price ratio matrix of three resource transfer participants and 3 types of resources is as follows:
wherein
Is the first
The preset standard value parameter of each resource transfer participant can define a vector
To indicate the manner in which, among others,
is as follows
A price ratio of the resource transfer participant to the first digital currency. For example, assuming that the preset reference digital currency is equivalent to U.S. dollars, i.e., one preset reference digital currency is equivalent to U.S. dollars, then for bitcoins its price is expected to be the price expected of the corresponding resource transfer participant for the bitcoin to exchange for U.S. dollars. In one embodiment, it may be assumed that the first digital currency is a reference, such as bitcoin as the first digital currency and a preset reference digital currency, and the second digital currency is an etherhouse, when the price expectation of a resource transfer participant for the first digital currency is 1, and the price expectation of the etherhouse of the second digital currency is 0.033, it indicates that the resource transfer participant exchanges 0.033 bitcoins for 1 etherhouse.
Setting the transfer reference value parameter of each digital currency as
The loss of each resource transfer participant can be expressed as:
. That is, what the scheme needs to determine is how to take P so that
And minimum. Reduction of Δ:
because of the fact that
Therefore, it is
Independent of the p-value. The price is selected only in relation to the quantity that each resource transfer participant wants to transfer and the preset standard value parameter. To ensure fairness, the variance of all resource transfer participants needs to be considered. The variance represents the balance condition of the transfer loss of the resource transfer participants, the greater the variance is, the greater the difference between the losses of the resource transfer participants is, and the smaller the variance is, the more balance the loss of the resource transfer participants is. In the following, the formula of the variance is defined:
order to

wherein p is 1 -p m Respectively representing the value reference parameters of the 1 st to the m-th digital currencies.
Further, in one embodiment, the demand amount of each of the resource transfer participants for each of the digital currencies is converted equivalently to an equivalent demand amount of each of the resource transfer participants for each of the digital currencies expressed in the preset reference digital currency, based on a price ratio of each of the digital currencies to the preset reference digital currency.
Each price ratio may represent a conversion relationship between each digital currency and a preset reference digital currency, and further may convert a demand of each resource transfer participant for each digital currency into a demand for a preset reference digital currency. It should be noted that, here, the required amount of each digital currency by each resource transfer participant is converted, and only the preset reference digital currency is used to represent the requirement of each resource transfer participant, and the type and amount of the digital currency actually required by each resource transfer participant are not affected.
Assuming that the price ratio of the ith digital currency to the preset reference digital currency is determined to be 1:2 through calculation, when the requirement of the resource transfer participant A is to buy 2 ith digital currencies, the requirement of the resource transfer participant A can be equivalently converted into the requirement expressed by the preset reference digital currency according to the price ratio of the ith digital currency to the preset reference digital currency: buy the ith digital currency (2) equivalent to 4 preset reference digital currencies.
Further, in a specific embodiment, the data processing method includes the following steps:
setting the transfer reference value parameter of each type of resource to be P = (P) 1 ,p 2 ,…p j …,p m ) T Representing, supposing that the currency of the first column in the resource transfer matrix is selected as the preset reference type resource, and transferring the reference value parameter p obtained by the method for all the type resources 1 To p m And the price of the preset reference type resource is equivalently converted into the equivalent demand quantity expressed by the preset reference type resource, and an equivalent demand matrix is established, for example, as shown in fig. 4. When the following conditions are met according to the judgment of the equivalent demand, the resource transfer is proved to be realized: firstly, each resource transfer participant buys and sells the same assets; ② the total buy amount and the total sell amount of each currency are equal.
Further, the process of resource transfer according to the equivalent demand matrix of each resource transfer participant includes:
s1, traverse all a starting from i =1 i1 When a is i1 >When 0, let a = a i1 Go through all a again starting from j =1 i1 When a is i1 <When 0, let b = a j1 。
S2, if | a | b |, then a |, then i1 =0，a j1 = a | b |; if | a |>| b |, then a i1 ∣a∣-∣b∣，a j1 =0。
S3, repeating the steps S1 and S2 when
, a i1 When =0And all the transfer objects and the transfer quantity of the resource transfer participants corresponding to the 1 st type of resources are determined.
And processing other types of resources by the same method to obtain the transfer objects and the transfer quantity of each resource transfer participant corresponding to each type of resource, and further generating a resource transfer scheme.
In one embodiment, the resource transfer process may be represented by fig. 6, where a transferor is a vertex of the graph and a transfer is an edge, and fig. 6 illustrates a transfer process including two types of resources, i.e., a type a and a type B, where a dotted arrow represents a matching resource transfer participation scheme of a, a solid arrow represents a matching resource transfer participation scheme of B, and a direction pointed by the arrow represents a direction in which the type resources flow.
Further, a transfer reference value parameter p of A, B and C types of resources is determined A =1，p B =0.5，p C =0.25。p A ：p B ：p C =1:2:4, i.e. 1 type resource a =2 type resources B =4 type resources C.
Still taking the equivalent requirement matrix shown in fig. 4 in this embodiment as an example, the determined transfer scheme is: for type resource a: c is transferred to A2 type resources A, and C is transferred to D2 type resources A.
For type resource B: a is transferred to B1 x 2=2 type resources B, d is transferred to B (3-2) x 2=2 type resources B, and d is transferred to c 3 x 2=6 type resources B.
For type resource C: a transfers to C1 x 4=4 type resources C, b transfers to d 3 x 4= 12C currencies.
The data processing method can perform demand matching on a plurality of resource transfer participants and a plurality of types of resource transfer in decentralized transfer, ensure fairness and atomicity of resource transfer, and solve the trust problem caused by centralization in the conventional resource transfer.
