Usability problems with points-a common problem that plagues both merchants and users. Merchants want to incentivize users to consume by points, but the application scenarios of points are often limited to a small range. For a user, the points of multiple merchants are usually owned, but the points owned by each merchant are very limited, and small points cannot be used, so that the user is embarrassed that the user owns considerable points but cannot use the points.
For solving the above technical problems, people have long searched for, for example, chinese patent discloses an integral intercommunication method based on block chain technology [ application number: CN201910075185.5], including: a requester initiates a point exchange request to the block chain point ecological alliance system through each platform; the system freezes the corresponding deposit of the integral; after receiving the request, the alliance system records the points which are converted and increased on the blocks according to the preset conversion ratio of the deposit to the points and broadcasts the information of the point blocks to each node on the alliance chain; after receiving the broadcasted integral block information, each node performs corresponding integral data processing; and transferring the security fund to the corresponding account name of the alliance system.
Although the scheme of using the block chain platform to communicate with a plurality of different platforms is proposed, certain defects still exist, for example, the scheme needs to use block chain integration, if a user needs to convert the integration of the merchant a into the integration of the merchant B, the integration of the merchant a needs to be converted into the block chain integration first, and then the integration of the merchant a is converted into the integration of the merchant B through the block chain integration, so that the problem of complex conversion exists. In addition, each merchant is still independent, mutual conversion of scores is realized only through the platform of the block chain, if a user needs to perform mutual conversion on scores of multiple merchants, the platform corresponding to each merchant needs to be connected into the block chain, so that the problem of complex operation exists, and the business effect of mutual drainage among the merchants cannot be realized.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The joint surface algorithm is an automatic market maker algorithm. In the block chain field and in the asset exchange scene, the automatic market maker algorithm can automatically exchange assets with the mobile bottom pool without matching the users. A constant product market maker algorithm is typically used that ensures that the product of two assets in the liquidity bottom pool will remain constant throughout before and after the exchange transaction. The constant product market maker algorithm is that before and after trading, the asset exchange rate changes according to the exchange trading volume, and the change of the exchange rate is called a sliding point. If the number of assets in the fluid bottom pool is small, the price slip point due to the exchange can be very large.
The applicant creatively thinks of applying the automatic market maker asset exchange system based on the block chain in the scene of point exchange, and a plurality of point issuers form a point union to construct a union block chain network to circulate the points on the block chain. The user uses the automatic market maker to exchange the points mutually, and the originally scattered points are collected for use.
The joint surface algorithm can be actually considered as a generalized formula of a constant product algorithm. In the constant product algorithm, the fluid bottom pool can only use two assets, while the joint surface algorithm allows multiple assets to be in the same fluid bottom pool. In the constant product algorithm, the ratio of the value of the two assets in the liquidity bottom pool needs to be kept 1: 1, that is, the value of the two assets in the asset pool is always equal. In the combined curved surface algorithm, the occupation ratios of various asset values can be specified, so that a more flexible exchange market can be constructed, and a larger exchange rate sliding point is avoided.
Therefore, the scheme provides a block chain point exchange method and system based on a joint surface algorithm. The system is based on an alliance block chain system, a plurality of point issuers form an alliance and start a block chain network, each point issuer negotiates the quantity and value proportion of an initial liquidity point asset bottom pool and issues corresponding number of points according to the negotiation, exchange intelligent contracts are deployed to automatically make market traders to provide mutual exchange of the points, then users can really use the exchanged points, and the point issuers inject or extract corresponding points according to actual conditions to dynamically adjust the liquidity point asset bottom pool.
The scheme simultaneously solves the difficult problem of point exchange and the mobility problem of constant product market maker algorithm, and deduces the exchange algorithm suitable for the point exchange according to the combined curved surface algorithm, so that the point exchange is directly realized for the user through the point exchange intelligent contract when the scheme is put into use.
As shown in fig. 1, the scheme is described in the following steps that a user exchanges a redemption point with a certain number of redemption points:
s1, a system receives a point exchange request of a user;
s2, extracting the points to be added, the points to be added and the number of the points to be added from the point exchanging request;
and S3, calculating the number of the released points according to the weights of the released points in the liquidity point asset bottom pool and the releasing number of the released points by the point releasing intelligent contract, and releasing the corresponding releasing number of the released points to the user.
Wherein the intelligent contract comprises an algorithm formula (1)
Bx is the current number of redeemed points x;
wx is the weight of the redeemed points x in the bottom pool of the liquidity points asset;
by is the current number of the added points y;
wy is the weight of the redeemed points y in the bottom pool of the liquidity points asset;
dx is the dispensing amount of dispensing points x, and Dy is the dispensing amount of dispensing points Y.
Preferably, the point redemption system further comprises an asset management system:
the system is used for monitoring the exchange rate of each point relative to other points in real time and informing the corresponding point issuer to carry out point injection or point extraction to balance the exchange rate when the exchange rate of a certain point is seriously deviated.
As shown in fig. 2, it is specifically determined whether the exchange rate seriously deviates from one integral by the following means:
and recording the initial exchange rate of each point relative to other points, and judging that the point has a serious exchange rate deviation problem when the absolute value of the exchange rate difference between the current exchange rate and the initial exchange rate of any two points of the certain point and the other points exceeds a deviation preset value. If the initial exchange rate of the points A and B and the initial exchange rate of the points A and C are recorded, the current exchange rate of the points A and B and the current exchange rate of the points A and C are obtained, when the absolute values of the difference between the initial exchange rate of the points A and B and the current exchange rate exceed the preset deviation value, and the absolute values of the difference between the initial exchange rate of the points A and C and the current exchange rate exceed the preset deviation value, the point A is judged to have the serious deviation problem of the exchange rate.
In addition, the accumulated amount of the liquidity accumulated asset bottom pool determines the amount of the exchangeable objects which can be born, so the asset management system is also used for monitoring the accumulated amount of the liquidity accumulated asset bottom pool in real time, and when the accumulated amount is less than the accumulated value preset value, each accumulated point issuer is informed to integrally inject or extract various accumulated point assets with the same value according to the exchange rate of the current liquidity accumulated asset bottom pool. Through asset monitoring on the flowing point asset bottom pool, the point issuer can inject or extract the point assets according to the actual conditions to dynamically adjust the flowing point asset bottom pool, and more flexible market exchange is realized.
