To address the storage capacity limitations and high costs inherent in the existing single-chain storage model of blockchain-based traceability systems, a strategy combining on-chain and off-chain storage using IPFS as an alternative storage architecture is proposed. The goal is to enhance the storage model while ensuring data storage stability. Storing frequently accessed information off-chain helps alleviate the excessive pressure on the blockchain caused by high-frequency queries, while ensuring the security and immutability of on-chain data. Additionally, IPFS technology expands storage capacity and reduces storage costs through its distributed storage, thereby improving data storage and retrieval efficiency. Experimental validation shows that compared to traditional single-chain traceability models, this storage optimization approach can reduce data storage time by 8.05% and data retrieval time by 30.97%.
