Description

Technical Field

[0001] The present invention relates to the technical field of government data tracing systems, and in particular to a government data tracing system based on smart contracts. Background Art

[0002] Smart contract (English: Smart contract) is a computer protocol designed to disseminate, verify or execute contracts in an information-based manner. Smart contracts allow for trusted transactions without a third party, which are traceable and irreversible. The concept of smart contracts was first proposed by Nick Szabo in 1994. Smart contracts are in digital form, which means that the contract has to be written into computer-readable code. This is necessary because as long as the parties reach an agreement, the rights and obligations established by the smart contract are executed by a computer or a computer network.

[0003] Smart contracts are standardized. Based on computer code, smart contracts can minimize the ambiguity of language and present it through a strict logical structure. The content and its execution process are transparent and visible to all nodes, which can observe, record and verify the contract status through the user interface.

[0004] Irreversibility. Once the conditions are met, the contract will automatically execute the expected plan. Given the factual input, the smart contract will inevitably output the correct result and be visualized in the display horizon.

[0005] Non-default. The transaction information on the blockchain is open and transparent. Each node can trace the transaction process recorded on the blockchain, and the probability of default is extremely low.

[0006] Anonymity. Based on the cryptographic principles of asymmetric encryption, zero-knowledge proof, ring signature, blind signature and other technologies, on the blockchain, although the transaction process is public, the two parties to the transaction are anonymous.

[0007] However, the existing carrier system for smart contracts is not convenient to move, and its structural stability and integration are average. Summary of the invention
