  1. 1. Presenter Name Presenter Title Date IBM Blockchain based on Hyperledger Fabric
  2. 2. What is a Blockchain network? 2 A set of nodes or peers … ... running a p2p CONSENSUS protocol ... ... to maintain a common record of transactions: the BLOCKCHAIN
  3. 3. 3 Introducing Blockchain for Business… Blockchain for Business Shared, replicated, permissioned ledger
  4. 4. © 2018 IBM Corporation Blockchain technologies can remove business frictions and reveals new opportunities for business transformation 4 Company A Company B Company C Institution D Regulator E Company D Saves time Transaction time from days to near instantaneous Removes cost Overheads and cost intermediaries Increases trust Through shared processes and recordkeeping Reduces risk Tampering, fraud & cyber crime
  5. 5. 5 Other types of blockchain exist – The first blockchain application – Defines an unregulated shadow-currency – Resource intensive • Blockchains for business are generally permissioned and private, and prioritize: – Identity over anonymity – Selective endorsement over proof of work – Assets over cryptocurrency is an example of an unpermissioned, public ledger:
  6. 6. © 2018 IBM Corporation 6 Hyperledger: A Linux Foundation project • A collaborative effort created to advance cross-industry blockchain technologies for business • Announced December 2015, now over 150 members • Open source, open standards, open governance • Five frameworks and three tools projects • IBM is a premier member of Hyperledger www.hyperledger.org Brian Behlendorf Executive Director Blythe Masters Board Chair Chris Ferris TSC Chair “A broad, cross-industry and open source approach is critical to advance the potential for blockchain and make it mainstream. Even beyond building out standards, creating common code will allow organizations to focus on creating industry-specific applications that enhance the value of this technology.” Arvind Krishna, Senior Vice President and Director of IBM Research

  18. 18. 18 Business Network definition
  19. 19. 19 – Domain specific APIs very attractive to mobile and web developers. Resources and operations are business- meaningful – Composer exploits Loopback framework to create REST APIs: https://loopback.io/ – Extensive test facilities for REST methods using loopback – Secured using JS Passport, giving >400 options for authentication – Composer provides back-end integration with any loopback compatible product – e.g. IBM Integration Bus, API Connect, StrongLoop – Outbound and Inbound (where supported by middleware) Systems of Record Integration
  20. 20. Open Governance Anyone can join or contribute Built from the ground up for enterprise With a maturity model to help companies move to production Performance Supports up to 1000 tps* Confidentiality and privacy Built-in channels for isolation and membership services for signing and encryption. Supports IBM Blockchain Platform. Modularity and flexibility Choice of consensus algorithms and programming languages Why Hyperledger Fabric?
