In recent years, traceability systems have been developed as practical tools for improving supply chain (SC) transparency and visibility, especially in health and safety-sensitive sectors like food and pharmaceuticals. Blockchain-related SC traceability research has received significant attention during the last several years, and arguably blockchain is currently the most promising technology for providing traceability-related services in SC networks. This paper provides a systematic literature review of the various technical implementation aspects of blockchain-enabled SC traceability systems. We apply different drivers for classifying the selected literature, such as (a) the various domains of the available blockchain-enabled SC traceability systems and relevant methodologies applied; (b) the implementation maturity of these traceability systems along with technical implementation details; and (c) the sustainability perspective (economic, environmental, social) prevalent to these implementations. We provide key takeaways regarding the open issues and challenges of current blockchain traceability implementations and fruitful future research areas. Despite the significant volume and plethora of blockchain-enabled SC traceability systems, academia has so far focused on unstructured experimentation of blockchain-associated SC traceability solutions, and there is a clear need for developing and testing real-life traceability solutions, especially taking into account feasibility and cost-related SC aspects.

Agri-food supply chains have a multitude of roles for the mankind. Among others, they encompass the primary, secondary and tertiary sectors of the economy; they are responsible for feeding the planet; they are associated with various environmental and social impacts. Therefore, their operation, efficiency and performance are crucial in many contexts. In this paper we investigate the transitions of agri-food supply chains towards two different goals: circular economy and resilience. Circular economy has been a focal priority in the EU and global agenda, which aims at redefining the patterns that have been associated with linear economy models in order to meet environmental, social, and economic challenges of our era. On the other hand, supply chain resilience is the capacity of supply chains to be prepared for unexpected risk events, act and recover promptly to probable disruptions, and return to their original position or move to a better ideal condition. In particular, we focus on the enablers and barriers for both goals and identify possible convergences and deviations. The former are expected to lead to win-win opportunities, whereas the latter will lead to trade-offs.
