DataArt Innovation Showcase Blockchain Billing

  1. 1. New York USA London UK Munich Germany Zug Switzerland New York USA London UK Munich Germany Zug Switzerland TAD Summit 2017 Blockchain Micropayments Demo
  2. 2. •Blockchain (few slides…)
  3. 3. Blockchain When do we need it? • Blockchain (distributed ledger) is a network that records ownership through a shared registry • It eliminates the need for central authorities to authenticate and clear transaction • Can be open, verifying anonymous transactions, or closed and requiring actors to be authenticated CENTRAL DATABASE CENTRALIZED LEDGER DISTRIBUTED LEDGER
  4. 4. Blockchain How it works
  5. 5. • Mobile banking and micropayments, including MI and IoT use cases • Device identity & authentication, data time-stamping and asset management • Contract-as-a-Service for enterprise-facing telcos • Manage SLAs for CSPs' own network services • An efficient billing system that accurately tracks usage of services and instantaneously charge their subscribers • NFV monetization, fraud prevention, wholesale reconciliation and data-integrity protection Blockchain Suggested Use Cases
  6. 6. Blockchain Technologies
  7. 7. •Blockchain Micro-Payments – Idea
  8. 8. • Create simple and efficient billing system that can accurately track subscribers' use of the services and instantaneously charge their subscribers • Streamline operational and business processes by adopting hybrid blockchain networks • Overwhelm blockchain scalability limitations • Building blocks: Telestax Restcomm, Speech Recognition AI, µRaiden Blockchain Demo Idea
  9. 9. • An open source payment channel framework for fast & free off-chain ERC20 token transfers between two parties • Complementary to the Ethereum blockchain • Business models involving frequent payments between the client and the service provider are not efficiently possible on current blockchains due to slow confirmation times and high transaction fees. • Using µRaiden, service providers can comfortably cover Pay-per-Use scenarios (APIs, digital content and utilities) via micropayments in Ethereum based tokens µRaiden read: Micro Raiden
  10. 10. •Demo
  11. 11. • Restcomm App requests for speech recognition services • Restcomm Media Server pays tokens for each word recognized by external Speech Recognition Service • µRaiden implements the ERC20-based authentication and micropayments • Everything works in the Kovan or Ropsten Revival testnets Blockchain Demo Architecture SIP MGCP RTP/UDP Speech API (wrapper) Restcomm RCML Media Server Ethereum Blockchain
  12. 12. • Part of the network of unidirectional payment channels • Managed by dedicated smart contract that works as an escrow* • No need to transact every micro-payment on the blockchain, so do not cost any gas • Transfers are secured and trustless, backed by an on-chain deposits • Few parameters: GAS Price, Channel Lifetime in Blocks, Deposit in Tokens • Can be closed by sender and receiver at any point in time *third party that holds and regulates payment required for two parties involved in a given transaction Blockchain Demo µRaiden Micropayment Channel
  13. 13. 1. Client ("sender") opens a micropayment Channel with the provider ("receiver") using Ethereum Wallets 2. Sender funds the channel and creates Deposit with a certain number of Tokens 3. Consuming the service, Sender sends signed Cheque (balance proof) to Receiver 4. Receiver verifies signature on the Cheque and decides on the further provisioning of service (Steps 3 and 4 can be repeated) 5. Receiver may decide to claim the collected Tokens from the channel and cashes the Cheque 6. Receiver closes the Channel Blockchain Demo Process BlockchainSender Receiver Channel Deposit Cheque 53 4 2 1
  14. 14. Three main parts: Driver, Billing Service, VR Service. • Driver – VR Service: binary format for communication through Java NIO Netty server • Driver – Billing Service: REST Spring Boot with embedded Tomcat • Billing Service – VR Service: REST, JSON format Spring Boot with embedded Tomcat • WebSocket is used for push notifications from Backend to UI in Billing Service (when a new Cheque generated) and in VR Service (when the new Cheque received) • UI for both applications implemented on Angular 2 Blockchain Demo Implementation
  15. 15. 1. Started with 1810, 2. Opened Channe#1 and deposit 50 balance is 1760 3. Spent 2 and 4 (one and two words are recognized) 4. Opened Channel#2 and deposit 50 balance is 1710 5. Creating new channel Sender informs Receiver that he may cashe the cheque 6. Closed the Channel#1, signed cheque and got back deposit minus 6, balance is 1754 Blockchain Demo Recording…
  16. 16. 1. Started with 1810, 2. Opened Channe#1 and put 50 as deposit, balance is 1760 3. Spent 2 and 4 from Channel#1 deposit, 4. Opened Channel#2 and put 50 as deposit, balance is 1710 5. Creating new channel Sender informs Receiver that he may cashe the cheque 6. Closed the Channel#1, signed cheque and got back deposit minus 6, balance is 1754 Blockchain Demo An Explanation… Channel 1 50 TKN, -2 TKN, -4 TKN Channel 2 50 TKN 1810 171050 2 4 50 441760 1754
