Blockchain has received the largest amount of attention in the analysed articles, the technology has been linked to the concepts of traceability and transparency very often [2,4,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28], moreover, smart contracts have been proposed by several articles as a companion technology for blockchain [15,29,30,31]. Although this technology has been the attention of many recent studies [8,17,32], most of these publications were mainly a bibliometric review of blockchain and supply chain papers, and propositions of blockchain benefits and applications that remained at demonstration and pilot study stages where an actual prototype implementation is still missing.…”
