Description

Internet-based cross-platform consumer green point subsidy coupon using method Technical Field The invention relates to the technical field of low-carbon consumption excitation and electronic commerce settlement, in particular to a consumer green point subsidy coupon using method based on internet cross-platform. Background The current consumer green point subsidy coupon system is deployed by mainly relying on an e-commerce and a local living platform, low-carbon commodities such as energy-saving appliances and organic foods are purchased through users, points are issued and commodity or service discounts are allowed to be exchanged in the platform, the green commodities are reselled to idle second-hand platforms by the users along with the expansion of the second-hand transaction market scale, the existing scheme adopts a closed-loop design in the platform, the coupon is only bound with an initial buyer account number, the point interests after the commodity is reselled automatically fail, part of emerging platforms try to introduce cross-platform mutual recognition alliances, the points issued by certain persons are allowed to be approved in cooperative merchants such as specific chain supermarkets, but the alliance scope is limited to head enterprises, and a second-hand transaction scene is not covered. The existing commodity resale scene has broken point value, namely, a voucher is strongly bound with an account number of a primary buyer, a secondhand buyer cannot inherit any green equity, even if the commodity has low-carbon properties such as an air conditioner with an energy efficiency identifier, point excitation returns to zero in new transaction, in addition, a secondhand platform such as a fish is not connected into a green point system, when the user resale the commodity, the residual point value cannot be transferred to the buyer, and rewards cannot be obtained due to the cyclic utilization of the green commodity, if the user tries to bind the primary voucher with the secondhand transaction, the original platform (such as an east), the seller, the buyer and the fish are required to be manually coordinated, and the existing cross-platform settlement protocol only supports the B2C scene and does not define the point circulation rules in the C2C transaction. In addition, a part of platforms adopt a tracing code secondary activation scheme, namely a unique two-dimensional code is added to commodity packages, a second-hand buyer can get a new small amount of coupons after scanning the code, but the scheme has two limitations that the scheme is only suitable for the unpacked commodities such as new products with packages and large household appliances and the like and cannot be deployed, the new buyer coupons are not associated with the original seller, the seller lacks resale power, and the scheme adopts a cross-chain coupon communication protocol, so that the exchange of points between certain east and certain clique is realized, the problem of ownership transfer authentication in the second-hand transaction is not solved, and the manual operation of the original buyer is still required to be transferred. Disclosure of Invention The present invention has been made in view of the above-described problems occurring in the prior art. The invention provides an Internet-based cross-platform consumer green point subsidy coupon using method, which solves the problems that the existing green point coupon is bound with a user account, rights and interests are broken during second hand resale, and cross-platform settlement relies on manual coordination and is low in efficiency. In order to solve the technical problems, the invention provides the following technical scheme: The embodiment of the invention provides an Internet-based cross-platform consumer green point patch coupon using method, which comprises the following steps: Step S1, a unique carbon right identifier bound with a low-carbon commodity is generated in response to the purchase of the low-carbon commodity by a user on a first transaction platform, wherein the carbon right identifier is generated by commodity coding, a purchaser identity and an initial carbon footprint value through hash operation; step S2, the coupon is associated with the carbon weight identifier and stored in a cross-platform alliance chain coupon pool, and the coupon pool is accessed into a plurality of heterogeneous transaction platforms; Step S3, when the fact that the commodity carrying the carbon right identifier is resale on the second-hand transaction platform is monitored, automatic triggering is carried out: releasing the first proportion of the coupon face value to a reseller as a recurring incentive; a second proportion of the coupon face value is assigned to the purchaser as inherited rights. As a preferable scheme of the consumer green point patch coupon using method based on internet cross-platform, the invention adopts SHA-256 algorithm, and the input paramet
