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 transacting via a two-tier federation chain. A method of transacting via a two-layer federation chain comprising a plurality of witness nodes and a plurality of service nodes, comprising the following steps: receiving signatures of both the initiator and the recipient service nodes of the transaction from the recipient service node of the transaction by the witness node, and processing the transaction data with at least part of the service data hidden by the zero-knowledge proof; Transaction witness; pushing the witnessed transaction data includingthe transaction data signed by the witness node directly to the originator and recipient service nodes of the transaction; generating fingerprint data by calculating a hash value of the transaction data and signing the hash value of the transaction data, and broadcasting the fingerprint data to the two-layer federation chain; and broadcasting a block of the fingerprint data to the two-layer federation 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 ...
