  11. 11. © 2016 IBM Corporation 11 Use Case – Blockchain Internet of Things and Government earthquake sensor network What? • Record seismic data from individual sensors in a public ledger (Blockchain) How? • Seismic model will verify timestamped recordings by sensors in the network to be belonging to the same earthquake event Benefits 1. No trusted third party required for registering and verifying individual seismic events 2. Easier to relate new damage to specific seismic event 3. events transparent to all network members

  13. 13. © 2016 IBM Corporation 13 Use Case – Smart Refrigerator What? • Value of connected smart devices limited by ability to interact with business systems How? • Blockchain to manage automated interactions with the external world • ordering and paying for food to arranging for its own software upgrades and tracking its warranty. Benefits 1. business value from connected technology 2. efficiencies in network and supply chains. 3. status transparent to all network members http://www.scribd.com/doc/252917347/IBM-ADEPT-Practictioner-Perspective-Pre-Publication-Draft-7-Jan-2015

  15. 15. © 2016 IBM Corporation 15 Use Case – Business to Business Contracts What? • Buyer wants efficient way of converting a purchase order into validated, self executing contract updated to reflect the status of the supply. • Agreement must be visible to the buyer, the seller, banks, logistics partners and other stakeholders. How? • Blockchain provides a shared record of the contract status which is updated as the contract progresses. • Available to all parties to the agreement, their banks and partners. Benefits 1. increased efficiency and transparency across the supply chain. 2. risk management improved through the near real time update of all contracts. Why?

  17. 17. © 2016 IBM Corporation Blockchain – not for all . . . POSITIVE Indicators 1. Managing contractual relationships 2. Complex business logic 3. Identity is important 4. Transactions need to be private 5. Market Approach needed 6. More than two parties 7. Looking to reduce costs 8. Want to improve discoverability NEGATIVE Indicators 1. Need high performance (millisecond) transactions 2. One organization involved (no business network) 3. Looking for a database replacement 4. Looking for a messaging or general transaction processing
  18. 18. © 2016 IBM Corporation 18 Summary 1. Blockchain is a shared, replicated ledger technology 2. Linux Foundation Hyperledger project: an open standards, open source, open governance Blockchain 3. Blockchain can open up business networks by taking out cost, improving efficiencies and increase accessibility 4. Blockchain addresses an exciting and topical set of business challenges, which cross every industry 5. Start identifying the value of blockchain technology in your business network
