Description

technical field [0001] The invention relates to the technical field of digital commodity transactions, in particular to a digital transaction system for financial derivatives based on trusted computing and smart contracts. Background technique [0002] Most of the current digital commodity trading platforms use centralized data storage and store all transaction details in a centralized manner, resulting in insufficient security and stability of transaction data between buyers and sellers. Once an irreversible error occurs on the platform, data may be lost, tampered with, or leaked Personal privacy, resulting in irreparable loss. In a fully centralized system, users' transaction data and personal privacy cannot be fully guaranteed in front of the platform's agreement, and it is difficult to truly get the recognition of both users. [0003] The third-party center also has the problem of untrustworthiness. Since the data of the digital commodity provider flows through the data...

Problems solved by technology

[0002] Most of the current digital commodity trading platforms use centralized data storage and store all transaction details in a centralized manner, resulting in insufficient security and stability of transaction data between buyers and sellers. Once an irreversible error occurs on the platform, data may be lost, tampered with, or leaked Personal privacy, resulting in irreparable loss

In a fully centralized system, the user's transaction data and personal privacy cannot be fully guaranteed in front of the platform's agreement, and it is difficult to truly get the recognition of both users

[0003] The third-party center also has the problem of untrustworthiness. Since the data of the digital commodity provider flows through the data trading platform, it may cache the provider's data without the data provider's permission, or even resell the provider's data, which affects Benefits of digital commodity providers from data transactions

[0004] In addition, because the blockchain cannot actively obtain real-world data, it brings a lot of inconvenience in some application scenarios, such as financial derivatives transactions, stable currency transactions, etc., which are extremely sensitive to off-chain real-time market application scenarios. Caused troubles, chronically damaged the interests of the platform, and was not conducive to the prosperity of the market
