This　research　study　aims　to　reveal　the　role　of　supply　chain　parameters　approved　by　blockchain　technology　toward　firm　performance　through　trust.　This　study　has　also　examined　the　moderating　role　of　government　support　between　trust　and　firm　performance.　The　underlying　theories　reinforce　the　usefulness　and　flexibility　of　a　supply　chain　in　regulating　daily　fluctuations　and　uncertainties　in　supply　and　demand.　Blockchain　technology　adoption　with　supply　chain　tactics　provides　a　more　suitable　environment　for　better　firm　performance.　Governments　address　legal　and　security　concerns　related　to　blockchain　technology　and　provide　clear　guidelines　and　standards　for　its　use　in　supply　chains,　which　build　trust　among　firms　and　stakeholders.　A　conceptual　model　has　been　developed　with　the　assistance　of　past　empirical　research　studies　and　associated　theories.　This　research　study　has　examined　the　following　relationships　from　a　sample　of　465　employees　from　textile　industrial　firms　listed　on　the　Pakistan　Stock　Exchange.　The　current　research　study　assesses　these　parameters　using　the　partial　least　squares　structural　equation　modeling　(PLS-SEM)　method.　The　analysis　showed　that　supply　chain　parameters　(alignment,　agility,　adaptability)　approved　by　blockchain　technology　positively　correlate　with　firm　performance.　Trust　positively　mediated　the　relationship　between　supply　chain　parameters　approved　by　blockchain　technology　and　firm　performance.　Furthermore,　government　support　positively　moderated　the　relationship　between　trust　and　firm　performance.　The　study　would　provide　directions　for　further　research.　These　findings　will　give　the　global　supply　chain　industry　valuable　insights　into　blockchain　technology　for　firm　performance.　In　theory,　this　research　study　would　contribute　to　the　scientific　literature　by　answering　how　trust　and　government　support　affect　the　overall　firm　performance.
