Recently,　the　Industrial　Internet　of　Things　plays　a　vital　role　in　the　new　round　of　technology　innovation　and　industry　competition,　where　the　identity　resolution　system　is　its　key　component.　However,　there　are　some　problems　in　the　existing　Handle-based　identity　resolution　architecture.　Therefore,　a　trusted　identifier　co-governance　architecture　is　proposed,　and　a　prototype　system　is　designed　and　implemented　in　this　article.　Specifically,　we　design　a　blockchain-based　decentralized　framework　for　identifier　service,　identifier　life　cycle　management　based　on　smart　contract,　and　a　data　storage　mechanism　for　a　trusted　identifier.　The　whole　architecture　could　solve　the　problems　of　single　point　of　failure,　data　tampering,　and　governance　deviation,　and　reduce　the　trust　cost　in　the　process　of　data　circulation.　The　simulation　results　reveal　that　the　system　has　achieved　good　results　in　terms　of　delay　and　throughput.　©　1979-2012　IEEE.
