- 4. What is Blockchain ?
- 5. In simple words if you ask ,I would say , “Block chain is decentralized database with strong consistency support.”
- 8. How Blockchain Works ?
- 11. 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
- 12. 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

- 18. Azure Blockchain as Service
- 19. 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

- 23. 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
- 24. 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.
- 25. 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

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 devicesDesigned to connect with existing apps and workflows Facilitates management with ledger- agnostic tools Enables customer choice in ledger technologies

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.
