As　a　new　generation　of　information　technology,　blockchain　plays　an　increasingly　prominent　role　in　social　operation,　bringing　significant　changes　to　the　economic　process,　social　organization　and　governance.　Blockchain　application　scenarios　are　complex　and　diverse,　with　many　computing　nodes,　scattered　locations　and　dynamic　topology　changes.　Security　threats　have　become　an　essential　factor　restricting　blockchain　development,　and　various　security　problems　have　become　increasingly　prominent.　The　blockchain　network　lacks　an　effective　security　management　mechanism,　resulting　in　the　frequent　flow　of　illegal　data　on　the　chain　and　malicious　attacks,　which　seriously　affects　the　operation　order　and　healthy　development　of　the　blockchain　network.　Based　on　trusted　computing　technology,　this　paper　carries　out　the　research　on　the　blockchain-oriented　management　platform,　constructs　a　distributed　blockchain　management　center,　carries　out　system　management,　security　management　and　audit　management　of　the　blockchain,　and　provides　a　safe　and　reliable　guarantee　for　the　stable　operation　of　the　blockchain　network.　©　2021　IEEE.
