**3. Blockchain technology**

Blockchain is an innovational technology that enhances customer service, drives end-to-end value, and increases the efficiency of operations [25]. Additionally, it allows distrusting or unfamiliar stakeholders to create shared and secure data records [26]. In sum, when an exchange of valuable data and goods is necessary, blockchain technology expedites transactions, streamlines the process, enhances transparency, reduces waste, and, ultimately, reduces cost [27]. Consequently, new types of internet and associated business models have been built off of this robust technology [22]. Blockchain promises to be the primary driver of secure and efficient economic and social systems in the future.
