“Y si tu frigo te hace la compra en el supermercado más adecuado?”

  1. 1. A Connected Fridge could do the shopping for your entire household Use case presentation for Blockchain Madrid
  2. 2. 2 © Worldline 2017 Who am I? – Passionate about what you can do with technology, not with technology itself • Worldline (Atos): European leader in Payments & Digital Transformation • Member of the Blockchain Workforce Group and global SPOC for Blockchain projects • Focus on leveraging technologies to improve current services/business lines or create new ones. • Let’s share an example of a Blockchain-based solution; approached via the use case, not the technology manuel.machado@worldline.com @twManuelMachado
  3. 3. 3 © Worldline 2017 • Smart Shopper Program • Why we would use Blockchain • How would it work • Value proposition & Business Model • Q&A & Next Steps Agenda
  4. 4. 4 © Worldline 2017 Home Appliance Innovators face 2 critical challenges Stand out (from an ocean of constant design & functional innovation) Stand out (from an ocean of constant design & functional innovation) + Strengthen customer engagement (buy more BSH appliances and services in between purchases) Customer perceives a differential value both in the short & long-term (make their daily life easier so customers are interested in increasing engagement) Image designed by Freepik
  5. 5. 5 © Worldline 2017 Smart Shopper Program – A solution to attract new customers & increase engagement with your brand Monitor groceries in the fridge Monitor technical functioning Monitor to … ...be smarter Learn from Purchasing Behavior Define Purchasing Profile Search Best Provider Generate Smart Shopping List Connect all appliances Monitor Cycles of Consumption Image designed by Asierromero / Freepik
  6. 6. 6 © Worldline 2017 Smart Shopper Program – Customers feel empowered, in control of what is purchased but unloaded of admin tasks Image designed by Asierromero / Freepik “I forget to check on maintenance or supplies for all my appliances. I get notified if anything is required and if I validate, everything happens automatically” “I decide my purchasing profile, which products I want to add to my shopping list automatically and which are my priorities (total basket price, Km 0, local shops, response time, …)” “My shopping list is automatically populated with all products I have chosen to monitor (dish-washer pads, milk, mayonnaise, etc.). I can modify it and launch an order to looks for the best supplier ” “The system learns from my monitoring and purchasing behavior , even of non-monitored products, so my shopping list is each time more accurate”
  7. 7. 7 © Worldline 2017 Smart Shopper Program – Principles to be both successful & feasible Customer satisfaction • Facilitate daily life • User in control • Independent ecosystem • Transparency Security • Participants to be approved • Total privacy protection (data to improve service) • Secure & fast transactions Common Core Platform • Core platform worldwide, customized locally: − Localization − Active functionalities − Local participants Background image designed by Freepik
  8. 8. 8 © Worldline 2017 Smart Shopper Program – Product range targeted in the short, medium & long term Short term Consumables & groceries linked to monitoring capacity of devices Medium term Home related services (home supplies, security, domotics, insurance, etc) not necessarily linked to monitoring. Long term Any service or product that may provide value to Program users (i.e. travel offers, family activities, etc.).

  10. 10. 10 © Worldline 2017 Blockchain - A shared database with specific characteristics Shared Publicly Decentralized Trusted Automated Secure Definition based on data from Autonomous Research “Blockchain Back-office Blockbuster” paper • Servers (nodes) maintain the entries (blocks) • Every node has a copy of the ledger and sees the new transaction data store in the blocks when created • No central authority require to approve transactions or rules • Anonymous user (permission-less) or not (permissioned) • Data is encrypted, need private key to see transaction content • Once recorded on a BC, data is immutable & irreversible. i.e. secured from tampering and revision. • New blocks are created only by network consensus. • It allows transactions to occur among unknown parties. • Software does not allow conflicting or double transaction to be added to the Blockchain. • Transaction can occur automatically once consensus reached. “A distributed database that maintains a continuously growing list of records, called blocks. Blocks contain validated transactions” (P2P)
  11. 11. 11 © Worldline 2017 Blockchain – Consensus to add Block to the Chain New block New Block Candidate Proof of Work Proof of Stake Vs Consensus Algorithm Network Consensus Blockchain Origin block Hash to spot fake blocks in the chain New Block as unique version of truth Network power to defend from attack Hashing Nothing-at- Stake Energy Consumption
  12. 12. 12 © Worldline 2017 Blockchain – Fits the use case (IoT + ecosystem) Easy to create a rich and autonomous ecosystem of suppliers. Fast and inexpensive transactions, even more with Smart Contracts. Transparent but protecting privacy. The lack of central control ensures scalability and robustness by mutualizing nodes resources, eliminating many-to-one traffic flows, decreases delay and overcomes the problem of a single point of failure. Security: BC realizes a secure network over untrusted parties which is desirable in IoT with numerous and heterogeneous devices. Fit & Challenges based on Seminar on “Seminar of Web Security and Privacy” by Prof. Alberto Marchetti-Spaccamela
  13. 13. 13 © Worldline 2017 Blockchain – Challenges for the use case (IoT + ecosystem)  Proof of Work: it implies too much processing power (computing power and electricity consumption) and longer response times.  Scalability: BC scales poorly as the number of nodes in the network increases. and IoT networks may contain a large number of nodes.  Storage: the BC ledger has to be stored on the nodes themselves and it will increase in size as time passes. That is beyond the capabilities of a wide range of smart devices such as sensors, which may have very low storage capacity. Fit & Challenges based on Seminar on “Seminar of Web Security and Privacy” by Prof. Alberto Marchetti-Spaccamela

  16. 16. 16 © Worldline 2017 High-level functional flow – Private BC, PoS, devices validated by customer New device to request participation in BC User to validate the new device via app User to fill purchasing profile Monitoring (cycles, functionality, Groceries,…) Automated generation of Shopping List User corrects Shopping List & Validates Appliance /Home Node searches for right Supplier The node finds the right SC issued by a Supplier The supplier node may look for a SC for delivery Delivery closes open SC & triggers payment Payment done via wallet or direct debit Learning from Behavior SC: Smart Contract
