Blockchain for the Enterprise
- 1. Blockchain for the Enterprise Iemke Kooijman Martijn Hulshof 25-11-2017
- 4. Experis Ciber and emerging technologies Blockchain Research questions: • What is blockchain: capabilities, strengths and limitations • What does the blockchain field look like (public/private blockchain): Key players • What scenarios legitimate blockchain technology? How: • Tech first approach, application driven • Multidisciplinary teams • Agile development Aim: • Build knowledge and share expertise • Identify valuable use cases for business
- 5. Goals & Agenda Session goal: Introduce core capabilities of blockchain technology and application in an enterprise context Agenda: Part 1: • What is blockchain? • SAP & Blockchain • Use case Part 2: • Hyperledger Fabric overview • Sample transaction flow • POC demonstration
- 6. What is Blockchain The purpose of blockchain is to enable secure value transfers across a distributed network without a need for trusted third parties. Key properties: • Decentralized (P2P) • Consensus • Cryptography for authentication & immutability • Programmable Blockchain is NOT: • Bitcoin • Internet 2.0
- 7. Gartner Hype Cycle - 2017
- 8. What is blockchain – Public deployment 1200+ Cryptocurrencies, $250.000.000.000 Market cap
- 9. What is Blockchain – Private deployment The quest for enterprise grade ‘blockchains’ • Reuse/modification of proven technologies • Focus on business networks (B2B) • Scaling benefits for transaction processing • Registration/enrollment procedures: Security and authorization concepts • Large open source communities driven by software vendors • Blockchain-as-a-Service PaaS offerings

- 12. Typical use case: Supply Chain Management
- 13. Typical use case: Supply Chain Management
- 14. Conclusion - Part 1 Making the case for blockchain • Blockchain is bleeding edge technology, still high on the ‘hype cycle’ • There is an increasing business interest into the capabilities of blockchain for driving standardization and process integration in business networks • Blockchain fits to the digital transformation paradigm; technological means to redesign business models and processes
- 15. Part 2 – Hyperledger Fabric Introduction • Fabric initially developed in-house by IBM • Code base contributed to Hyperledger foundation, which is hosted by The Linux Foundation since January 2016. Mission statement (excerpt): ‘Create an enterprise grade, open source distributed ledger framework and code base, upon which users can build and run robust, industry-specific applications, platforms and hardware systems to support business transactions.’ ‘Create an open source, technical community to benefit the ecosystem of HLP solution providers and users, focused on blockchain and shared ledger use cases that will work across a variety of industry solutions’ • Next to Fabric, Hyperledger also hosts other blockchain projects like Sawtooth and Burrow
- 16. Hyperledger Fabric - Basic Architecture
- 18. Hyperledger Fabric – Sample transaction flow • Scenario: - 2 organizations: Org A, Org B - 2 Peer nodes - A user from Org A wants to submit a Purchase Order transaction • Client A submits a proposal to write to the ledger via a signed ‘propose message’ to Endorsing Peers A and B. Source: http://hyperledger- fabric.readthedocs.io/en/latest/txflow.html
- 19. Hyperledger Fabric – Sample transaction flow • The Endorsing Peers (Peer A, Peer B) verify - If transaction proposal is well formed - If transaction has not been submitted before - If the signature is valid - Client authorization (write operation) Inputs are ‘processed’ against current state and a signed response value (read/write set) is send back as a ‘response message’. • The client inspects and compares the results
- 20. Hyperledger Fabric – Sample transaction flow • The client assembles endorsements into a transaction payload via ‘transaction message’. • Transaction send to Ordering Service Nodes (OSN) • OSN deliver blocks to Peer Nodes, which verify: - Endorsement policy conditions - No intermediate state changes for variable set If okay; Tx = validated, if not Tx = invalid
- 21. Hyperledger Fabric – Sample transaction flow • Peer nodes append block with tx’s to their chain. - Immutable via hash chain • Valid transactions update (write) the current state database • Peer emits event to client after commit; - ‘Transaction is added’ and - Is ‘validated’ or ‘invalidated’ • Org A now purchased the radices and the transaction is immutably stored in the ledger
- 22. Hyperledger Fabric – POC Perishables SCM • Objectives: - Accurately track perishable products accross globalized end-to-end supply chain - Use smart contract to process payments depending on contractually agreed shipping conditions • Participants: Grower, Quality official, Customs office, Shipper, Importer, Supermarket, Consumer • Notes: - IBM Bluemix (Cloud) BaaS trial used: including a CA, 1 peer node, 1 ordering node, client - Hyperledger composer - Playground
- 23. Hyperledger Fabric – POC Demo
