Ebay, OLX and OpenBazaar are all examples of websites/protocols where two people can trade goods. To prevent fraud, parties usually use an escrow or a middleman who takes decisions when things go wrong. Devery is a blockchain based system to make this process more reliable and trustworthy. Devery aims to protect both brands and customers from fraud. It does this by associating products with a unique id which is stored on the blockchain. Customers can scan products and verify it with the blockchain using the Devery mobile app. Devery works on top of Ethereum. EVE tokens will be used by suppliers to pay for creating and storing unique identifiers of products on the blockchain.
