The　supply　chain　is　a　system　that　comprises　multiple　entities　such　as　suppliers,　manufacturers,　carriers,　customers,　etc.　Data　sharing　safely　between　these　entities　is　vital　for　the　success　of　a　supply　chain.　This　paper　proposes　a　secure　supply　chain　data　sharing　scheme　based　on　blockchain　and　IPFS,　including　decentralized　architecture,　data　management　of　capability-based　access　control　mechanism　and　message　acquisition　mechanism　based　on　the　publish-subscribe　model.　Further　more,　a　BIZi　storage　method　is　proposed　to　enhance　the　reliability　of　the　above　solution　and　streamline　the　backup　of　data　by　combining　smart　contract,　the　Bitswap　protocol　of　IPFS　and　the　Zigzag　code.　Finally,　a　prototype　of　a　supply　chain　platform　is　implemented　based　on　the　Ethereum.　The　performance　test　shows　that　BIZi　can　save　more　storage　resources　at　the　same　fault　tolerant　rate.　©　2023　SPIE.
