Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings.

[0043] First, the manual mentions the basic concepts related to the practical proxy chain system for further explanation

[0044] (1) Practical proxy chain

[0045] The utility proxy chain is a blockchain system that supports smart contracts and is the key entity of the entire system. It consists of five entities: Transaction Operator (TO), Transaction Operator Group (TOG), Client, Smart Contract and User. T0 is an organization or individual who wants to provide token exchange services and get paid through token exchange; TOG is a group of multiple TOs, which is the smallest unit for declaring token exchange services. Suppose all T in TOG o s are all rational. Clients are participants who wish to exchange assets with other clients on different blockchain systems. Smart contracts include proxy contracts and token contracts: proxy ...

Abstract

The invention discloses a novel cross-chain system based on an intelligent contract and a trusted computing technology, and the system comprises a system setting module which is used for deploying a token contract and a DO system; a TOG setting module which is used for establishing a TOG; a token generation module which is used for transferring a certain amount of deposit to an effective TOG deposit pool and putting the transaction record and a certain amount of service charge into a proxy contract; a token exchange module which is used for exchanging tokens among other clients on an actual proxy chain according to an existing fair exchange protocol by using an original key pair (PKiEC, SKiEC) of the client on the EC; and a token withdrawing module which is used for supporting the customer to withdraw the token on the practical agent chain. According to the novel cross-chain system based on the smart contract and the trusted computing technology, a cross-block chain asset exchange function can be effectively realized.

Description

technical field [0001] The invention belongs to the field of cryptography in information security, and more specifically relates to a new type of cross-chain system based on smart contracts and trusted computing technology. Background technique [0002] Since Satoshi Nakamoto proposed Bitcoin in 2008, the concept of blockchain has attracted worldwide attention. As an open ledger system, blockchain effectively combines cryptography and distributed consensus mechanisms to ensure data transparency and tamper-proof modification. Due to the excellent characteristics of the blockchain system itself, it is considered to be the core technology of digital currency. So far, the blockchain has supported thousands of digital currency projects, and the value of the top 100 digital currencies has exceeded $1 trillion. In addition, blockchain technology is widely used in many fields, such as Internet of Things, file storage, and digital rights management (DRM). [0003] However, due to ...
