Embodiment Construction

[0043] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention more clearly understood, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

[0044] figure 1 It is a schematic flowchart of the blockchain-based secure payment method applied to the system in the embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0045] Step 101: After receiving the order execution completion notification sent by all product execution terminal nodes through the blockchain network, the third-party platform node will execute the order according to the customer code data, order code data, and order execution content pre-stored in the blockchain network. T...

Abstract

The invention discloses a safety payment method and system based on a block chain and a third-party platform node, and the method comprises the steps that after all product execution terminal nodes complete the execution of an order, the third-party platform node carries out the execution of the order according to a customer code, an order code, an order execution content code and order timestamp code data which are pre-stored in a block chain network; the first password lock is unlocked through the first secret key, so that the first password lock loses the restriction effect on the second secret key; the third-party platform node uses a second key to unlock a second coded lock according to one of the code data pre-stored in the block chain network, a product demander parameter input through the product demander node and a product provider parameter input through the product provider node, so that the second coded lock loses the restriction effect on the delayed payment code; and the financial institution node matches the sent delay payment code with a pre-stored delay payment code, and the safety payment process is completed after successful matching. According to the invention, secure payment can be realized based on closed-loop restriction.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a blockchain-based secure payment method, system and third-party platform node. Background technique [0002] This section is intended to provide a background or context to the embodiments of the invention recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, when purchasing products (physical products or service products) through a third-party platform, in order to ensure the safety of customer funds, it is necessary to deferred payment for the product, that is, when the product order is actually completed, the product payment will be actually transferred to the product provider. account. In the process of deferred payment, the customer's money is at risk of being arbitrarily controlled by the buyer (product demander) or seller (product provider), or arbitrarily misappropriated by third-par...
