Embodiment 1

[0071] figure 1 This is a schematic flowchart of the off-chain one-to-many payment method with decentralization in Embodiment 1 of the present invention. like figure 1 As shown, the off-chain one-to-many payment method with decentralization in this embodiment includes the following steps:

[0072] Step 100: Generate public parameters, a first private key, a first public key, a second private key and a second public key of the blockchain system. The public parameters of the blockchain system are generated by the issuer; the first private key is the private key generated by the payer, the first public key is the public key generated by the payer; the second private key is a private key generated by the payee, and the second public key is a public key generated by the payee.

[0073] Entering the security parameters into the blockchain system can automatically output the public parameters of the system. According to the public parameters and security parameters of the system,...

Embodiment 2

[0097] This embodiment is the system corresponding to Embodiment 1, figure 2 It is a schematic structural diagram of the off-chain one-to-many payment system with decentralization in Embodiment 2 of the present invention, such as figure 2 As shown, the off-chain one-to-many payment system with decentralization in this embodiment includes: an initialization module 210 , a channel establishment and coin deposit module 220 , a verification module 230 , a payment module 240 , a payment module 250 , and a settlement module 260 .

[0098] The initialization module 210 is used to generate public parameters, a first private key, a first public key, a second private key and a second public key of the blockchain system; the public parameters of the blockchain system are generated by the issuer; The first private key is a private key generated by the payer, the first public key is a public key generated by the payer; the second private key is a private key generated by the payee, and ...

Embodiment 3

[0152] Figure 4 This is a structural diagram of the off-chain one-to-many payment system with decentralization in Embodiment 3 of the present invention. like Figure 4 As shown, this embodiment includes three types of entities: nodes, payers and payees. Among them, the public and private keys of the payer and the payee can be expressed as (SK, PK).

[0153] Figure 5 This is a schematic diagram of the off-chain one-to-many payment system and basic cryptographic tools with decentralization in Embodiment 3 of the present invention. like Figure 5 As shown, in this embodiment, the initialization is completed independently by the node, the payer and the payee, the channel establishment and coin deposit are independently completed by the payer, the verification is completed by the node, the payment is completed by the payer, and the payment is completed by the payee Done, settlement is done by the payer and the payee. Each process involves cryptographic tools and basic crypt...

Abstract

The invention discloses a one-to-many payment method and system with a decentralization characteristic under a chain. The method comprises the following steps: generating a public parameter, a payer private key, a public key, a payee private key and a public key of a block chain system; a payer generation channel establishing a coin-pressing transaction bill, and locking the advance payment amountand the freezing amount; the node of the block chain system verifying the effectiveness of the advance payment amount, the freezing amount and the channel establishment and the currency pressing request transaction order; if yes, storing the channel establishment and the mortgage transaction list in a block chain system; if not, rejecting the channel establishment and the mortgage transaction bill; the payer signing the payment amount and sending the payment sign to the payee; the payee verifying the effectiveness of payment; if yes, the payee accepting the transaction; if not, the payee rejecting the transaction; and the payee carrying out settlement with the node of the block chain system, and extracting the collection amount to the account address of the payee. According to the method,problems of low flexibility and centralization of off-chain payment in a payment system can be solved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a one-to-many payment method and system under the chain with decentralization characteristics. Background technique [0002] Electronic payment systems try to provide users with a payment method that is as flexible and efficient as possible. Electronic payment usually advocates the use of a principal, that is, a trusted third party is used to complete transactions and provide users with a flexible service. The existence of trusted third parties, although flexible, also exposes certain preferences of users and reduces user privacy protection. For application scenarios with high privacy protection, a decentralized blockchain system has been developed. In 2008, Satoshi Nakamoto proposed the blockchain and used it to serve Bitcoin's public transaction ledger. [0003] Blockchain systems have the following five key advantages: 1. Blockchain facilitates online transactions throug...
