The great advantage of blockchain technology in the trust mechanism makes it quite popular in the production field in recent years. With the research purpose of enhancing the trustworthiness of blockchain technology in the consumer market, this paper constructs a blockchain-based product traceability model by integrating core elements such as ledger-splitting technology, smart contract, and cross-ledger event notification mechanism. Meanwhile, for the problem of heavy data communication burden in the product production process, we introduce the sharding technology in the PBFT consensus algorithm and propose the SHT-PBFT algorithm. In the design work of traceability and production information protection scheme, Hyper ledger Fabric is selected as the underlying technology platform, and the smart contract based on BLAKE2 algorithm is used to process the data. Combined with the transaction process of the product supply chain, the blockchain-based information protection scheme is established. Under the proposed information traceability model and information protection scheme, consumer recognition and adoption are set as independent variables and relevant independent variables are selected to construct a model for regression analysis. Among them, Blockchain technology’s own advantages (Technicaladvantages) (6.169*) and high cost (Highcost) (8.901*) positively influence consumers’ perception of sustainable packaging and brand credibility of Blockchain technology.
