In　the　past　few　years,　blockchain,　the　underlying　technology　of　Bitcoin,　has　received　considerable　attention　from　academia　and　industry.　It　is　widely　accepted　that　blockchain　technology　causes　disruptive　changes　in　supply　chain　operations　that　can　overcome　supply　chain　difficulties　encountered　in　realizing　information　sharing,　maintaining　traceability　in　the　entire　process　and　improving　operational　efficiency.　However,　the　application　of　blockchain　technology　in　the　supply　chain　field　is　still　in　its　infancy,　which　limits　an　understanding　of　its　potential.　This　article　uses　descriptive　and　content　analysis　to　review　publications　related　to　blockchain-based　supply　chains　between　2017　and　2020　inclusive.　To　fully　explore　research　on　blockchain-based　supply　chains,　four　well-designed　questions　are　proposed　and　addressed,　namely,　the　value　of　blockchain　in　supply　chains,　the　attraction　of　scholars　to　particular　supply　chain　themes,　the　development　of　research　methodologies　and　illustration　types　in　adopting　blockchain　in　supply　chains,　and　the　types　of　industries　involved　in　blockchain-based　supply　chains.　The　results　reveal　that　there　is　growing　interest　in　applying　blockchain　technology　to　supply　chain　operations.　A　detailed　analysis　of　findings　is　provided　to　identify　the　future　opportunities　of　blockchain-based　supply　chains,　including　prospects　for　tertiary　industries　and　concerted　efforts　that　are　necessary　to　explore　sustainability　themes.　This　article　provides　valuable　information　to　help　scholars　and　practitioners　better　determine　the　relevant　research　topics　to　accelerate　the　development　of　blockchain-based　supply
