The invention relates to the technical field of
data processing, in particular to an ecological credit
traceability system based on a block chain, and is characterized in that an equipment entity trust source is established through a physical anchoring registration module, and an equipment composite
fingerprint including an environment data hash value, an equipment operation state abstract and a
quantum signature is generated through a
quantum enhancement packaging module; and forming a
quantum enhanced
metadata packet in combination with the time anchor points. The dynamic purification module outputs a purification
data set with a credibility
score and a purification track proof, and the polymorphic
verification contract module generates a dynamic confidence coefficient. The double-chain storage engine generates spatio-temporal anchor points. And the three-
channel integration module generates a final value integral. And the entropy reduction feedback center forms a recursive
verification closed loop. And the enterprise credit rating engine embeds the dynamic confidence coefficient into an ecological value dimension to realize cross-domain
coupling of
environmental data and enterprise credit, and finally solves the problem of end-to-end credible
traceability of data under a chain in scenes such as
industrial emission monitoring and the like.
