Block chain asset coupon payment method and system based on legal digital currency

Abstract

The invention discloses a blockchain asset coupon payment method and system based on legal digital currency, and the method comprises the steps that a first user side initiates an ownership transfer application of assets on a chain, and writes a first hash value and first timeout time into a blockchain; the second user side initiates an operation of confirming agreement of ownership transfer to the block chain; the first user side sends the first hash value and the second timeout time to the first digital currency operation mechanism system; the system generates a hash time locked digital currency string, and transfers the hash time locked digital currency string into a digital currency account of a second user; the first user side transmits a first random number to the blockchain, the blockchain generates a second hash value based on the first random number, and if the second hash value is consistent with the first hash value and the current time is less than the first timeout time, the asset ownership is modified to the first user; and the second user terminal uses the first random number to unlock the digital currency coin string. The coupon payment of the assets on the chain can be directly completed by using the out-of-chain funds, and the fund risk caused by the introduction of a third-party platform is avoided.

Description

technical field [0001] This application relates to the technical field of blockchain, in particular to a method and system for payment against blockchain assets based on legal digital currency. Background technique [0002] DVP (Delivery Versus Payment) settlement refers to a settlement method in which after a bond transaction is concluded, on the settlement date designated by both parties, the bond and funds are simultaneously delivered relative to each other and are mutually a delivery condition. On the blockchain, the atomicity of blockchain transactions can naturally guarantee the payment of funds and assets on the chain. However, in order to use the atomic nature of blockchain transactions to ensure the bond payment of funds and assets on the chain, the funds outside the blockchain must be transferred to the chain to be stored in the form of tokens, which will inevitably require the introduction of a third-party platform to complete the exchange. In and out operations....

Secondly, after the funds outside the chain enter the platform, the platform is likely to form a fund pool, which is likely to cause capital risks. At present, thunderstorms caused by the fund pool are not uncommon.
