Table 1

Comparison of logistics traceability solutions.

Literature	Important method	Solution
TPLI: A Traceable Privacy-Preserving Logistics Information Scheme via Blockchain [1]	Development prototype verification traceability	Implementing a prototype system using hyperledger
Blockchain-Based Supply Chain Traceability: Token Recipes Model Manufacturing Processes [2]	Proposing the token to calculate the gas cost	A linear relationship between gas cost and the product is proposed to define the relationship between ingredients and products
Research on Traceability Algorithm of Logistics Service Transaction Based on Blockchain [3]	Traceability algorithm of logistics service transaction	Through the proposed algorithm, the end-to-end traceability service of logistics service is realized
