This invention discloses a trusted
carbon footprint storage and intelligent
traceability system for gold recycling based on
blockchain and AI technologies, belonging to the intersection of green finance technology and
environmental protection technology. The
system adopts a four-layer architecture: the
data acquisition layer binds batch IDs through GS1 encoding and integrates multi-
source data through IoT sensors, a
mobile app, and edge preprocessing; the AI
processing layer accurately calculates the
carbon footprint based on a dynamic LCA model, optimizes process parameters through deep
reinforcement learning, and simulates emission
reduction potential; the
blockchain storage layer uses a consortium
blockchain (PBFT
consensus) + IPFS storage, deploying smart contracts for storage and
verification to automatically generate CDCEER carbon credits; the
application layer provides
traceability queries, ESG dashboards, regulatory audits, and green finance interfaces. This invention solves the problems of data fragmentation, inefficient calculation, and difficulty in value conversion, achieving trusted management and value conversion of the entire
carbon footprint process, helping enterprises reduce costs and increase efficiency, comply with emission reduction regulations, and promote the green upgrading of the recycled precious
metals industry.
