A Model of Decentralised Distribution Line Using Layer 2 Blockchains.

At least one-third of the food produced for human consumption is lost and wasted due to inefficient perishable product distribution plans. Currently used distribution plans are static and centralised as a single entity decides on a distribution plan where products may move along a predefined path. In this paper, we developed a dynamic distribution plan generation algorithm where distribution paths are dynamic. We used blockchain offline channels to develop decentralised, secure, and privacy-preserving dynamic distribution plans in a multi-party supply chain. Our algorithm generates distribution plans using real-time quality information about perishable goods so that products may be sold before their shelf life expires. Our algorithm ensures the privacy of all actors in a supply chain as inventory and order information of all actors remains privacy-preserved.
