Building a blockchain for business with the Hyperledger Project



Hyper ledger is one of the fastest-growing open-source blockchain communities anyone can help lead it and dozens of companies are working together building a blockchain fabric that can support production business networks the work started last year with a simple framework to test the interaction between applications and secure blockchain networks and it's allowed us to test use cases in supply chain Capital Markets manufacturing and healthcare here's what we learned first we learned that permission blockchain networks that require every peer to execute every transaction maintain a ledger and run consensus can't scale very well and they can't support true private transactions and confidential contracts so the hyper ledger community designed fabric v1 to deliver a truly modular scalable and secure foundation for industrial blockchain solutions the most notable changes that peers are now decoupled into two separate runtimes with three distinct roles endorser committer and concentr here's how it works say you run an organic market in California and I grow radishes on my farm in Chile you and I are in a blockchain network that supports transactions between various markets growers shippers banks and others say I agree to sell you my radishes at a special low price but I need the other markets that buy for me to continue buying at the standard price they shouldn't be able to execute our confidential agreement and find out the details of our deal in fact if they aren't part of the deal the transaction shouldn't appear on the ledger fabric v1 handles all this my app looks up your identity from a membership service and then sends the transactions only to our peers both of our peers will generate a result in this two-party agreement the transaction requires both of us to render the same result but in transactions with more parties other rules can apply then the peers send the validated transaction back to the application which sends it to a consensus cloud for ordering and then the ordered transactions are sent back to the peers and committed to the ledger but to get my radishes to your market there are many other parties involved some need to know that my radishes have been verified and checked into a shipping container others need to handle bills of lading customs inspections financing insurance but most of these parties don't need to know about our special price now think about our transaction running out of network handling all the markets all the farms shippers facilitators the whole supply chain this is the same pattern needed by many industries anywhere we need to manage confidential obligations to each other without passing everything through a central authority b1 delivers one network with everyone working together while ensuring confidentiality scalability and security and that's what we're building right now and we could use your help so how do we get there go to hyper letter to find out
