3. Today’s Agenda
o Why Blockchain ?
o Blockchain basics
o AvailableBlockchainFrameworks
o AzureBlockchainasService
o AzureBlockchainworkbench
o Demo

4. Why Blockchain ?

5. In a‘trust gap’
environment ,you
introduce athird
party thateveryone
should trust.
Problem :Difficult to Track Asset Transfer in Business Network
The third party
introduces fees.
Inefficiencies in data
reconciliation
..Inefficient ,Expensive ,Vulnerable

 Consensus
 Immutability
 Provenance
 Finality

7. How Blockchain Works ?

9. By supporting multi-party workflows on a shared network

10. Blockchain Usecase for
KYC & International
Trade
Blockchain Usecase for
KYC & International
Trade

11. 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.

12. Know your customer(KYC)

13. Know your customer(KYC)

16. 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.

17. Mining
Miners collect transactions into blocks
Then submit a proposal for a block after solving a cryptographic puzzle

22. Azure Blockchain as Service

23. 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

27. And makes developing an end-to-end blockchain
app a huge undertaking
Manually deploy

Orchestrate
signing, hashing
and routing
Store smart

reference data
Synchronize data
with off-chain DB
Ingest messages
and events
Extend

Manage keys
Customize

Build web

Integrate with
existing business
apps
Configure
consortium
network
Link identities to
federated systems
Write business
logic

28. 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.

29. Everything required to create an app in one simple interface
But not with Azure Blockchain Workbench
Simplify

Accelerate

34. 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.

35. Azure Blockchain
Service
Deploy, manage and scale
permissioned blockchain
networks with a fully-
managed service
