The guideline demonstrates how multiple GS1 Standards can be utilized in a blockchain ecosystem to optimize data sharing. For example, the EPCIS (Electronic Product Code Information Services) standard allows supply chain partners to capture transactional information about supply chain events (e.g., when a product was shipped and when it was received) and share that information with their trading partners. EPCIS is in use today across various industries and helps document product chain of custody across trading partner networks when used for blockchain. Common use cases for blockchain in the supply chain include food and drug traceability, product sourcing transparency and order-to-cash process automation in retail.
