The Commerce CO-OP, the first brand and shopper consortium, is an Ethereum-based blockchain protocol that supports the free exchange of data across the retail supply chain, spanning suppliers, manufacturers, distributors, retailers, shoppers and logistics providers; the network of parties that make, move, and sell products shoppers enjoy. With the Commerce CO-OP, external entities currently entrenched between supply chain participants will no longer be able to exploit their leverage over the ecosystem.
