With　the　intelligent　development　of　terminal　devices　and　the　growing　applications　of　device-to-device(D2D)communication　technology,　terminal　devices　can　share　resource　through　a　direct　link.　To　improve　the　overall　service　capabilities　of　the　network　edge,　a　blockchain-based　D2D-assisted　multi-access　edge　computing　architecture(BD-MEC)for　resource　sharing　is　proposed.　In　BD-MEC,　considering　the　factors　of　the　delay,　energy　consumption,　and　payment　overhead,　an　offload　decision-making　based　on　game　theory　for　multi-user　scenario　is　proposed　to　meet　the　needs　of　different　users.　Moreover,　in　view　of　the　malicious　behaviors　such　as　denial　of　service　or　payment,　a　smart　contract-based　resource　sharing　protocol　and　dispute　handling　method　are　proposed,　which　uses　the　blockchain　to　force　the　sharing　parties　to　comply　with　the　resource　sharing　protocol　to　achieve　safe　resource　sharing.　Simulations　show　that　BD-MEC　can　effectively　the　reduce　delay,　energy　consumption,　and　payment　of　computing　tasks.　©　2021,　Editorial　Department　of　Journal　of　Beijing　University　of　Posts　and　Telecommunications.　All　right　reserved.
