Abstract

The invention discloses a smart contract protection system based on a trusted environment, including a client, block chain nodes, a data provider, a trusted environment, a non-trusted environment, a smart contract information processing module (A), a block chain node information transmission module (B) (such as a node interaction interface in the Ethereum), an input data transmission module (C), a smart contract execution module (D), a local contract information storage pool (E) and a block chain smart contract storage pool (F). The client is in communication connection with the block chain nodes. The data provider is in communication connection with the block chain nodes. The block chain nodes are in communication connection with one another. The technical problem that the copyright of smart contracts cannot be protected and the rights and interests of smart contract users are damaged due to the fact that the information of smart contracts may easily leak in the existing smart contract system and the technical problem that data may be stolen due to data leakage are solved.

Description

technical field [0001] The invention belongs to the field of smart contract security, and more particularly relates to a method and system for protecting smart contracts based on a trusted environment. Background technique [0002] Smart Contracts are a set of commitments defined in digital form, which control digital assets and stipulate the rights and obligations of contract participants. Smart contracts are automatically executed by computer systems. The execution process of smart contracts is the process of data processing . Essentially, a smart contract is an if-then way of interacting with real-world property in a computer system. Although the concept of smart contracts was proposed earlier, due to the lack of systems or technologies that can support the characteristics of smart contracts, the goal of smart contracts is difficult to achieve. [0003] Blockchain (Blockchain) technology is widely used in the financial field because of its decentralization, transparent ...
