Purpose

The present paper is aimed at 1) performing a systematic literature review (SLR) on applications in the perspective of sustainable agri-food supply chain (SC) of blockchain technology (BCT); 2) analyzing the selected literature, focusing on the advantages of the sustainable uses of the blockchain of the aforementioned SC and 3) presenting an outlook and research directions capable of addressing unresolved problems.

Design/methodology/approach

The SLR was conducted using detailed criteria to identify academic articles. Moreover, specific keywords and databases were used. The time frame considered included the years 2010–2020.

Findings

The review analysis indicates that the use of BCT or BCT supported by ICT/IoT contributes to sustainability of agri-food production. However, this technology can lead to several challenges such as scalability, privacy leakage, high cost and connectivity problems.

Research limitations/implications

The paper demonstrates that BCT can widely use agri-food supply chain due to its intrinsic characteristics. However, it is not excluded that the criteria chosen may not have identified important articles regarding BCT, the agri-food sector and sustainability.

Originality/value

Although the body of academic literature published on this topic is expansive, the effect of BCT on the agri-food SC's sustainability aspects has not yet been adequately analyzed. Thus, the article is aimed at investigating how BCT is used in the SC. In particular, the article is intended to update information about BCT and its impact on sustainability.

可持续农业食品供应链的区块链技术

目的

本文旨在1）从区块链技术（BCT）的可持续农业食品供应链（SC）的角度对应用进行系统的文献综述（SLR）; 2）分析所选文献，重点关注上述SC的区块链可持续利用的优势，以及3）提出能够解决未解决问题的前景和研究方向。

设计/方法/方法

使用详细标准进行SLR识别学术文章。此外，使用了特定的关键字和数据库。所考虑的时间范围包括2010-2020年。

发现

审查分析表明，使用BCT或ICT / IoT支持的BCT有助于农业食品生产的可持续性。但是，该技术可能会导致一些挑战，例如可伸缩性，隐私泄漏，高成本和连接性问题。

研究局限/意义

本文证明，BCT由于其固有的特性而可以广泛地使用农业食品供应链。但是，不排除所选择的标准可能尚未确定有关BCT，农业食品部门和可持续性的重要条款。

创意/价值

尽管有关此主题的学术文献广泛，但BCT对农产品SC可持续性方面的影响尚未得到充分分析。因此，本文旨在研究如何在SC中使用BCT。特别是，本文旨在更新有关BCT及其对可持续性的影响的信息。
