Internet　of　Things　(IoT)　is　a　promising　technology　that　attains　significant　consideration　in　diverse　industrial　areas,　i.e.,　agriculture,　engineering,　logistics,　trading,　ecological　examining,　security　surveillance,　energy,　and　healthcare.　IoT　gains　much　more　attention　with　the　rapid　advancement　of　wireless　communication　and　sensor　networks　as　millions　of　intelligent　devices　get　involved　in　IoT.　These　intelligent　devices＇　raw　data　must　be　captured　and　processed　to　support　decision-making.　However,　IoT　applications　trust　the　central　server　for　information　storage,　processing,　and　mediators　for　wireless　transmission.　Consequently,　it　can　leak　the　information　and　lead　to　high　costs　and　delays.　Hence,　data　security　is　the　leading　interest　for　the　IoT.　Blockchain　technology　can　be　deployed　to　overcome　the　security　and　effectiveness　of　the　gigantic　data　in　IoT.　Blockchain　is　studied　as　a　key　to　permitting　storing,　processing　and　sharing　of　data　in　an　efficient,　secure　manner.　In　addition,　reinforcement　learning　can　convene　the　high　data　rate　requirements.　It　will　help　us　to　optimize　the　performance　of　the　blockchain-enabled　IoT　framework.　©　2022　IEEE.
