"Another initiative worth watching is Provenance, an open data project spearheaded by designer and technology strategist Jessi Baker.The name pretty much says it all. Her idea is to “tag” products with certified data identities about origin that both businesses and consumers can trust.Central to this is blockchain, the secure transaction processing technology that underlies bitcoin.You can think of blockchain as a digital footprint that keeps track of transactions or status changes along a path of relationships. It works across decentralized networks, which makes managing supply chain data one natural application, Baker said. Her idea: Every product has a story to tell."
