Blockchain is a type of distributed ledger that enables a network of participants to record, store, and share information in a secure manner. Because blockchain-based data sharing is peer-to-peer, there is no centralised authority controlling the ledger. In a nutshell, blockchain has enormous potential in retail because of its ability to increase transparency and trust among retailers, consumers, supply chain participants, and payment gateways. Blockchain enables all retail network participants to see what is going on in the system in near real-time without granting control to a single party. https://www.dunitech.com/Blokhain-in-retail.aspx
