Blockchain technology is a distributed database, an innovation tool in the agri-food supply chain in processes such as production, distribution, marketing. In this research work, the blockchain technology application in agri-food security processes was evaluated, establishing the best conditions for its adoption in companies, this proposal synthesizes the contributions as a disruptive technology, for this, the information was collected from the period 2018-2020 from the Scopus and Web of Science bases, performing an analysis of the information using the Atlas TI 8.4 software, establishing the focus of the research on a network of codes suggested by some authors. It was found that the contribution of Blockchain for the years of study was traceability 26%, supply chain 17.5%, technological development 10.4%, trust 9.8%, among others. It is concluded that establishing the theoretical link between technology and traceability processes in supply chains, traceability in the agri-food sector is essential to certify information of interest to the stakeholder group. This is because traceability is the transcendental element of the food safety system that allows guaranteeing control in the supply chain when processes are being recorded and enriching the databases, which can be available to the final consumer to check the details of the production cycle and that technological elements generate competitiveness in companies with blockchain in their procedures, promote high levels of transparency, data security, decentralization, among other terms associated with trust, and a better relationship with the consumer is developed and a greater number of sale increasing profitability.
