App Development using Azure Blockchain as Service

In this session we covered blockchain overview ,architecture and use-cases using Azure Blockchain as Service. We have discussed how we can create consortium ,invite nodes using Azure Blockchain as Service and use Azure workbench as integration tool with existing application.

3. Today’sAgenda o Why Blockchain ? o Blockchain basics and Dapps o Available Blockchain Frameworks o Azure Blockchain as Service o Azure Blockchain workbench o Demo
4. Why Blockchain ?
5. How Blockchain Works ?
9. Problem No one trusts anyone else Solution Accept proposals for transaction order and reward winning proposals Consensus Different ordering can lead to double spending Agreement on the order of transactions
10. Mining Miners collect transactions into blocks Then submit a proposal for a block after solving a cryptographic puzzle Block 4561 Hash of 4560 Block 4562 Hash of 4561
12. Smart contract ledgers Ethereum
13. By supporting multi-party workflows on a shared network Buyer Appraiser Insurer Lending bank Property inspector Land registry Seller’s agent PROPERTY PURCHASE Cross-organizational workflow Multiparty auditing Asset transfer and provenance
14. Ethereum Platform Client application Server-side application Ethereum Network Code web3j API Data
15. Smart Contract Development and Deployment
16. Azure Blockchain as Service
17. Azure Blockchain Service (PREVIEW) o Deploy fully managed blockchain networks in a few simple clicks. Offload network management so you can focus on application logic o Govern at scale with built-in governance and codeless consortia management o Build blockchain apps with confidence using the dev tools you love and the apps you rely on today o Capture, react to, and store ledger data off-chain

Sensors and IoT (unstructured) Transaction Builder (Logic Apps) Logs (unstructured) Service Bus Azure Blockchain Service Media (unstructured) Files (unstructured) Business/custom apps (structured) Power BI Azure IoT Central Application Insights Key Vault Virtual Networking Azure AD Power Apps Event Grid Flow READ AND ROUTE ATTEST TRANSFORM INGEST Blockchain data manager DATA MANAGEMENT Functions Logic Apps SQL Cosmos DB MySQL Machine Learning Studio Apps PostgreSQL
19. Azure Blockchain Data Manager
20. Azure Workbench
21. And makes developing an end-to-end blockchain app a huge undertaking Manually deploy ledger Orchestrate signing, hashing and routing Store smart contract reference data Synchronize data with off-chain DB Ingest messages and events Extend capabilities API management Manage keys Customize integrations Build web client Integrate with existing business apps Configure consortium network Link identities to federated systems Write business logic
22. Challenges 1. Months of development time and hundreds of thousands of dollars to create a PoC 2. Difficult to connect to our existing IT infrastructure. 3. Spending all of my time scaffolding together an infrastructure, not writing smart contracts. 4. Sensitive data on an unsecure platform.
23. Everything required to create an app in one simple interface But not with Azure Blockchain Workbench Simplify development Accelerate time to value Innovate with confidence
24. It connects with common business tools Data platform (Ml/bi) Secure off- chain execution Monitoring and security 3rd party services Federated identity Identity and key management Enterprise ledger Horizontal SaaS and adapters Client apps and devices Designed to connect with existing apps and workflows Facilitates management with ledger- agnostic tools Enables customer choice in ledger technologies
25. Setup Process Setup Ethereum POA network Register Azure AD tenant Deploy Azure Work Bench Deploy Blockchain Applications
26. Consortium architecture
27. Azure Work Bench
28. Useful services from Azure that we used Azure Active Directory Storage Blob Logic APP Event Grid AAD was used for User management as the user didn’t need to worry about his blockchain public address or private key. AAD also helped with role management, as we could define a hierarchy of roles in AAD, which propagates to what a specific user is allowed to do in workbench. The logic app helped our application to execute some actions based on some events received in the events grid e.g. send email notifications, create scheduled jobs etc. The Storage Blob was used to help manage storage of the physical location of the financial instrument document. The app can access the files through a hashed link to the location on the Storage Blob. The event grid contained all actions and events that have occurred in the blockchain. We used the logic apps in conjunction with the event that is read from the event grid to send notifications and create scheduled jobs based on the event type.
29. Azure Blockchain Service Deploy, manage and scale permissioned blockchain networks with a fully- managed service Blockchain Data Manager Integrate with the data sources and applications you already use to manage multi-party workflows Azure Blockchain Tokens Create, deploy and manage TTI-compliant tokens with a fully- managed service Azure Blockchain Development Kit Integrated IDE experience using the Ethereum tools you already know and love Develop confidently with a rich portfolio from Microsoft
30. Blockchain Usecase for KYC & International Trade
31. Compliance (KYC,AML) Problems & deficiencies ✓ Work done in collecting KYC information unnecessary replicated by multiple institution . ✓ Isolated view of customer and their transaction insufficient to detect money laundering. ✓ Uncertainty in knowing if implemented practices are sufficient (over stringent policy hurtful for business.) ✓ AML process are too fragmented and dependent on subjective human decision.
