An introductory presentation on Corda along with a demo of an application based on a supply chain problem.

Transcript

1. Meeting Corda: A blockchain platform built for the JVM Dimos Raptis
2. Agenda • Problem description & current landscape • High-level overview of Corda & key concepts • Demo • Analysis of the CorDapp
3. What is Corda Corda is a platform for executing distributed applications (called CorDapps), which allow multiple mutually distrusting nodes to transact with each other safely and as seamlessly as possible The platform is written in Kotlin and runs on the JVM. CorDapps can be developed in any JVM language, but they are mostly written in Java or Kotlin.
4. Current landscape
5. A sample problem - supply chain Some issues: • N2 integration problem • Business consensus • Authentication between parties • Dispute resolution • The cost of introducing a new organisation Distributor A Distributor B Distributor C
6. Corda overview
7. The network Main operations: - Permissioning / identification - discovery
8. The ledger Data shared on a need-to-know basis
9. Corda states
10. Transactions
11. Transaction chains
12. Contracts
13. Consensus 2 forms of consensus • Uniqueness consensus • Validity consensus
14. Flows
15. A supply chain CorDapp
16. Demo
17. Architecture
18. State structure
19. Flow structure
21. Benefits • Easier integration via shared protocol • Business consensus via shared logic & notaries • Authentication provided out-of-the-box by the network • Easier dispute resolution via digital signatures • Low barrier to entry for a new participant
