Nowadays　traditional　techniques　of　living　and　earning　are　being　transformed　to　modern　smart　technologies,　taking　their　inspiration　from　the　emerging　trends.　Agriculture　and　its　supply　chain　are　also　one　of　the　major　domains　of　research　that　need　attention　for　its　growth　especially　in　developing　countries　like　Pakistan.　Food　safety　and　its　supply　are　drawing　the　world＇s　attention　towards　its　importance　and　people　are　focusing　on　it　because　of　health　hazards.　This　research,　presents　a　Combo　smart　model　with　a　novel　scheme　for　the　transformation　of　traditional　agriculture　to　smart　agriculture,　taking　into　consideration　both　blockchain　and　Internet　of　Things　(　IoT)　characteristics.　The　system　proves　to　be　reliable,　automatic,　open,　and　biological　food　tracks　built　with　the　features　of　Blockchain　IoT　devices.　This　system　provides　equal　opportunity　to　all　stakeholders　involved　in　the　agricultural　food　supply　chain;　even　they　are　not　familiar　with　each　other　and　may　not　trust.　IoT　devices　are　added　to　the　smart　model　to　reduce　human　interference　for　data　recording　and　verification.　For　validation　purposes,　the　proposed　scheme　is　compared　to　our　own　scheme,　which　uses　only　IoT　devices　deployed　in　the　monitoring　field　without　a　blockchain.
