A double blockchain-based consumption model using a gamification social environment

The quality of food goods is one of the main characteristics that a supply chain have to satisfy in a highly competitive market. The Covid-19 pandemic is changing the rules of consumption, especially encouraging online purchasing methods, whereby consumers are more oriented to consult safe and certified information regarding the quality of products and/or each member of supply chain. In fact, there are still many people who have distrust of e-commerce platforms and systems, especially for perishable products such as food, precisely because they should be forced to trust information that in general may not reflect the truth. To face these issues, we propose a new consumption model based on the combined use of a permissioned and permissionless blockchain, integrating social gamification mechanisms to enable engagement and rewarding mechanisms. In particular, the idea is to define an always connected production and consumption cycle orchestrated by the two blockchains, where the permissioned one is applied to the supply chain in order to manage and activate the relationship between its members using the technology of smart contracts, while the permissionless one is applied and publically visible at the consumer level and allows notarizing consumers’ feedback, opinions, etc. about the quality of the products and the members itself. The previous “social” elements are completed with some gamification rules enabling the consumers to get a specific status within the referred community and tangible rewards to spend in that supply chain and, at same time, increasing the trust level in quality of products and processes.
