Payment method and device based on block chain

Abstract

The invention relates to a payment method and device based on a block chain. The payment method comprises the following steps that S1, a payee application determines the number of pass certificates tobe transacted; S2, a payer uses a client to pay, selects a to-be-used pass, can set the upper limit of the payment quantity, and the payment application of the payer transmits a payment data packet corresponding to the payment to the application of the payee through the data transmission channel; S3, the payee obtains a payment data packet provided by the payer, packs the payment data packet together with the payment data packet into a transaction push upper link according to the transaction number determined in the S1, waits for the egress to pack the transaction into a block, and queries atransaction ID related to the payment data packet to obtain a transaction result; and S4, the wallet of the payer continuously queries the transaction ID related to the payment data packet through theinterface provided by the block chain until the transaction ID is returned to be valid. The payment data packet is generated offline, the transaction time is shortened, and a payer can set the maximum amount of payment in a personalized manner.

Description

technical field [0001] The present invention relates to the technical field of blockchain-based digital asset circulation, in particular to a blockchain-based payment method and device. Background technique [0002] Online payments such as traditional POS machines, credit cards, and QR codes have been greatly promoted to solve the problems of counterfeit money and change that are prone to occur in cash transactions. But there are still many challenges. For third-party organizations such as banks, there are third-party organizations that have closed down, data is not transparent, it is difficult to supervise, and non-standardization causes difficulties in interaction between different organizations. Each bank needs to do extra work. Cross-border payment And other issues. For credit cards, there are problems such as high handling fee, slow payment, limited scope of application, and easy loss. In addition, there are a large number of potential payment scenarios and tokens tha...

Problems solved by technology

However, due to the consensus problem of digital currency and technical barriers, this problem is always difficult to solve and difficult to promote

In addition, it takes about 10 minutes for Bitcoin to dig out a block. To ensure the irreversibility of transactions, it takes 1 hour to wait for 6 blocks to be confirmed.

For large-value transfers and cross-border transactions, digital currency payments will indeed shorten some time and costs, but for small payments, paying with Bitcoin is far less cost-effective than paying with legal currency

[0004] The introduction of blockchain technology can solve some data and centralization problems. However, most blockchain systems currently do not have commercial-level processing speeds and often have high handling fees. The designed public chain has the characteristics of high speed, high security and high standardization, which provides the possibility for new blockchain-based mobile payment
