In　recent　years,　the　research　and　application　of　blockchain　applied　in　e-government　has　been　increasing.　The　characteristics　of　blockchain,　such　as　non-tamper,　verifiable　and　inspirable,　have　been　well　applied　in　confirming　the　rights,　accountability,　and　assessment　of　government　data　resources,　and　other　unresolved　problems　over　the　years.　Well,　the　decentralized　feature　is　naturally　inconsistent　with　the　strong　central　feature　of　the　government　so　that　the　application　of　common　blockchain　technology　in　e-government　cannot　support　the　government　regulatory　mechanism　effectively.　To　solve　this　problem,　this　paper　proposes　a　strong　supervision　model　of　blockchain　based　on　the　Threshold　Ring　Signature　algorithm　(TRS).　Further　experiments　show　that　the　process　and　results　of　signature　voting　by　using　this　model.　Compared　with　the　common　blockchain,　the　strong　supervision　model　can　control　the　error　rate　of　the　chain　information　and　increase　the　flexibility　of　blockchain　so　as　to　enhance　the　integration　application　of　blockchain　and　e-government.　©　2020　IEEE.
