thanks for sharing. I still have hard times understanding how blockchain can be used efficiently and trust minimised for supporting supply chains. Where d

I have struggled with this concept for 2 years, probably because I have no dealings with supply chains (other than coffee). I'm not sure how most currently work. But big ideas I've gathered from people working on this seem to be around getting good, structured, and interoperable data, which is not just a more streamlined database with reliable data but also allows for better models to be built around that data. Obviously when more people have root access to better data good things can be built. Similar to what we see now with Instagram/Twitter/Lens: The data for who liked your first post exists in each of these. The data for who your top supporters are exists in each of these. Only Lens gives you root access to all your data and we're seeing amazing things being built which could never happen in the first two because of that data. So applying this to a coffee industry example: If I buy a bag of coffee from a local coffee shop I must rely on them to give me information about the beans. Most places provide very little information (if any). When I buy green coffee and roast it myself I get an **incredible** amount of information from the importer. Attached are some images of what I mean. It's too much for the average consumer, but some people want to know some of this data. So what would happen if everyone along the way posted their information to Ethereum? Coffee supply chains typically work like this: Individual farms grow and pick a small number of beans Collectives bundle everything together Processors turn the coffee into something which can be roasted Exporters gather this coffee and sell it worldwide Importers buy and distribute locally to roasters Roasters sell to brands, cafes, restaurants, and directly to consumers. Consumers buy a cup or bag they know very little about. So take what we're doing with root access in Lens (building apps, building social networks, etc), and apply it to all of the potential data above. Composable data, making things exponentially easier for each participant in the chain (including the end consumer) and enabling new things to be built. All that to say nothing of sustainable payments! Whew, thank you for coming to my TED Talk 🙏
