A talk given by Jessi Baker of provenance.org at OuiShare 2015. Every product has a story. Provenance was founded to help us understand our material world through empowering great producers of products to make product supply chains more transparent. There is a huge opportunity for decentralised applications - powered by the blockchain, to help bring transparency and traceability to product supply chains. The blockchain presents a huge opportunity to build powerful tools for social and environmental justice. Products are more than the metrics we shop by. Provenance started as a project - Project Provenance - set up to try and help make making transparent, starting with the world’s best makers willing to adopt a transparent approach. But what actor or organisation could be trusted to broker all data about every product’s supply chain in order to facilitate making salient information transparent? The truth is that no single organisation can ever do this. Until recent years a centralised system with a governing third party was the only conceivable way to achieve data and transaction transparency along supply chains. The blockchain - a computing system that gives power to a crowd of even conflicted actors to cooperate in trading anything - including information, in a transparent, secure, decentralised way. No one organisation has control, identity can be protected and history can always be audited - never deleted. We believe the blockchain can revolutionise what we can know about products and how we can keep track of materials. We are building a Dapp - Decentralised Application - on the Ethereum Blockchain to give businesses the individuals a system to make information about how products are made transparent. The Provenance Dapp can facilitate end-to-end transparency by passing information along the supply chain securely on the blockchain.
