OSA Decentralized (OSA DC) is a real-life blockchain and AI application for retail, the world’s biggest industry. The decentralized marketplace provides AI-driven solutions to retailers, manufacturers, and consumers. More than 10 global retailers and manufacturers already use the solution, which may become part of OSA DC decentralized marketplace in the future. Systematic inefficiencies cost the retail industry approximately $500 billion annually. OSA DC neutralizes these inefficiencies by uniting disconnected parties (manufacturers, retailers, consumers, and third parties) within a single Ecosystem, thus fixing three major issues that hinder the retail industry today: 1 - Inventory tracking Inventory tracking: the blockchain will reduce overstocking and understocking, problems that cost retailers $400 billion every year. 2 - Consumer trust Consumer trust: the blockchain’s immutable ledger will provide more reliable product data to prevent businesses from abusing consumer trust. 3 - Product waste Product waste: OSA DC will minimize supply chain product waste that loses retailers $100 billion in potential profits annually.
