A　trusted　distributed　industrial　data　governance　solution　was　designed　based　on　blockchain　technology　in　order　to　address　the　issue　of　the　lack　of　a　unified　product　data　sharing　service　in　current　industrial　systems,　which　limited　users’　access　to　credible　product　traceability　information.　This　solution　enabled　efficient　and　secure　product　data　sharing　and　governance.　Product　data　was　compressed　and　encrypted　off-chain　by　the　data　generator　before　it　was　submitted　to　the　blockchain　system.　The　system　supported　off-chain/on-chain　data　access　through　two　types　of　blockchain　transactions　(producer　transactions　and　data　transactions)　in　order　to　ensure　the　availability　of　product　data　during　the　off-chain　process.　A　hybrid　access　control　mechanism　was　implemented　to　encrypt　product　data　and　share　secret　keys　exclusively　with　authorized　data　users.　This　solution　effectively　protected　the　privacy　of　product　data,　provided　fine-grained　access　control,　and　ensured　end-to-end　traceability　of　the　entire　product　data　generation　process.　Performance　tests　showed　that　the　computation　and　communication　costs　during　the　key　generation　phase　did　not　exceed　81.592　ms　and　2.83　kB　respectively　on　the　secp256k1　elliptic　curve　(providing　128　bit　security).　The　data　submission　phase　incured　cost　of　no　more　than　50.251　ms　and　3.59　kB,　the　data　update　phase　did　not　exceed　251.596　ms,　and　the　data　retrieval　time　remained　under　311.104　ms.　Performance　comparisons　with　similar　schemes　confirmed　the　efficiency　of　this　solution.　©　2025　Zhejiang　University.　All　rights　reserved.
