Abstract

The invention discloses a Fabric-based delivery payment application method and a Fabric-based delivery payment application system, and relates to the technical field of block chains. The method comprises the steps that a buyer transaction terminal generates a pre-payment address and a composite key, pays pre-payment to the generated pre-payment address and then sends the pre-payment address and the composite key to a seller transaction terminal, and both the pre-payment address and the composite key contain cargo information and preset cargo delivery time; the seller transaction terminal receives the advance payment address and the composite key, and delivers goods after the information contained in the advance payment address and the composite key passes the verification; and if the buyertransaction terminal confirms that the goods are received within the preset goods delivery time, the seller transaction terminal sends the composite key to the buyer transaction terminal, the buyer transaction terminal carries out signature assignment on the composite key, then the buyer transaction terminal sends the composite key after signature assignment to the seller transaction terminal, and the seller transaction terminal owns advance payment and ends the transaction. The method can effectively guarantee the safety of advance payment.

Description

technical field [0001] The present invention relates to the technical field of block chain, in particular to a method and system for cash on delivery application based on Fabric. Background technique [0002] Blockchain technology originated from the paper "Bitcoin: A peer-to-peer electronic cash system" written by Satoshi Nakamoto. It has attracted widespread attention due to its characteristics of decentralization, collective maintenance, openness and transparency, non-tamperability, and traceability. [0003] In Bitcoin, there are four payment types, namely P2PK (Pay to Public Key), P2PKH (Pay to Public Key Hash), MS (Multiple Signature) and P2SH (Pay 2Script Hash), among which P2SH is the most flexible, which locks The hash value of the script is used as the receiving address. In the P2SH payment type, when spending money, the unlocking script and the locking script are put together and interpreted and executed by the virtual machine. If the result is true, the unlockin...
