Description

Payment confirmation system

The present invention relates to a payment confirmation system, and more particularly to a payment confirmation system for transaction on a blockchain.

In response to the booming global blockchain, various blockchain products such as e-tickets and digital copyrights have also emerged in the country, but companies have developed blockchains that ensure real transactions and ownership cannot be tampered with. The platform, however, is unable to complete subsequent transactions because of the lack of a Delivery of Payment System (DvP System) that can be connected to the blockchain platform. The main reasons are as follows.

First, cryptocurrencies are not available: if it is the design of public blockchain technology such as Bitcoin or Ethereum, any blockchain-based transactions are based on cryptocurrencies, but because cryptocurrencies are not legal It should not be regarded as a legal payment tool in China. Therefore, if domestic consumers use blockchain products to purchase cryptocurrency or sell blockchain products to obtain cryptocurrency, they will lose the transaction security they deserve.

Second, transactions on the blockchain need to be confirmed: because cryptocurrencies cannot be used by blockchain operators, if domestic consumers want to buy blockchain products, or domestic merchants want to sell blockchain products, they still need Use payment methods provided by existing financial institutions, such as credit card, transfer, and Automated Clearing House (ACH), but at the same time, financial institutions need to confirm the validity of the transaction on the blockchain.

For example, if a certain seller sells a digital copyright to a certain B, a certain B transfer gives a certain A, and a certain A delivers a digital copy of the copyright certificate to a certain B, but if there is a dispute over the transaction afterwards, the delivery of a certain A has a record. On the blockchain, but a B's payment is not recorded on the blockchain. Therefore, a certain A may deny the payment and claim the loss of his rights, which is unfavorable to a certain B. Conversely, if a certain company first delivers digital copyright, but a certain B does not pay the promised amount, then a certain A cannot pass the blockchain to prove that a certain B has not fulfilled its obligations. It can be seen that the confirmation of payment based on the blockchain is very important for the transaction on the blockchain, and it is an extremely problem to be solved.

Accordingly, it is an object of the present invention to provide a payment confirmation system that provides confirmation of transactions on a blockchain.

Thus, the payment confirmation system of the present invention is applicable to a merchant computer system and a blockchain network, the merchant computer system generates a transaction instruction corresponding to a transaction content, and notes a corresponding transaction content on the blockchain network. Transaction record. The payment confirmation system includes a payment confirmation verification node, a payment and payment server, and a payment confirmation server.
