Embodiment Construction

[0030] Preferred embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Details and functions not necessary for the present disclosure are omitted in order not to obscure the understanding of the present disclosure.

[0031] Note that similar reference numbers and letters refer to similar items in the figures, so that once an item is defined in one figure, it need not be discussed in subsequent figures.

[0032]In this disclosure, the term "blockchain" includes, but is not limited to, technologies related to distributed storage, peer-to-peer networks, consensus mechanisms, encryption algorithms, and the like. The term "consortium chain" usually refers to a blockchain formed by multiple organizations or institutions in the form of a consortium. Trust and consensus mechanisms have been established between consortium participants through contracts or other forms, and the functions of constructing blocks and links are l...

Abstract

The present disclosure relates to a method of conducting transactions via a two-layer consortium chain. A method for conducting transactions via a double-layer consortium chain including multiple witness nodes and multiple business nodes, comprising the following steps: the witness node receives from the transaction receiver business node via the transaction initiator and receiver business node The two sign, and process the transaction data that hides at least part of the business data through zero-knowledge proof; transaction witness; push the witnessed transaction data including the transaction data signed by the witness node directly to the initiator and receiver of the transaction node; generating fingerprint data by calculating the hash value of the transaction data and signing the hash value of the transaction data, and broadcasting the fingerprint data to the two-layer consortium chain; and sending the fingerprint data The blocks of are broadcast to the two-layer consortium chain.

Description

technical field [0001] The present disclosure relates to a method, a device and a double-layer alliance chain system for conducting transactions via a double-layer alliance chain. Background technique [0002] In recent years, instead of the traditional centralized trading system, new trading methods based on blockchain technology and distributed ledger technology (DLT: Distributed Ledger Technology) have been developed. [0003] When using blockchain technology for transactions, transactions are packaged into corresponding blocks, and all nodes on the blockchain have a public ledger of transactions recorded in chronological order. According to the nature of the blockchain, the blocks on the blockchain are locked and connected, which makes it impossible to tamper with the data recorded in the block without modifying other blocks in the blockchain. However, when it comes to critical business data that needs security protection or isolation, it can only be logically isolated ...
