6. Question: !
What is new and profound in Blockchain that cannot
be done with traditional database servers? !
©2018DSAPPSINC

1. Look at what blockchain technology consists of.!
2. Compare a server update with a ledger update and understand benefits of shared ledgers.!
3. Examine how cryptographic chaining of data blocks in a blockchain ledger boosts trust.!
4. Understand why the elimination of intermediaries revolutionizes the world of computing.!
5. Examine several use cases and blockchain’s immense benefits to the world of edge computing.!

7. Goal of blockchain technology is to build and maintain
trust through shared distributed, immutable and highly
trustable ledgers that enable multiple parties to prove
ownership, achieve consensus and transact automatically
through smart contracts without need for intermediaries !

8. Distributed ledgers more
trustable than a central server!
We made a commitment and acted on it, !
We pushed the button and told the server!
We made a commitment and acted on it, !
We recorded in a highly trustable and
distributed blockchain ledger!
Server update! Ledger update!
The server was down.
Did we really act?

9. Commitments and
actions are recorded and
set in stone, in an
immutable ledger.
Blockchain Basics!

10. Blockchain technology provides the ability for N parties
to directly record and execute a trusted agreement !
without an intermediary, institution, escrow agent,
broker, supervisor or the cloud!
dsapps

11. Without blockchain
Blockchain changes the world of contracts, the foundation of
business and living commitments since humans have existed !

12. Blockchain Requirements!
Immutable Distributed Ledger
Trusted, Visible, Verifiable
Transactions
Smart Contracts

13. A highly trusted app from
the last century!
I cannot trust the bank,
but I can always trust
my passbook!
All financial transactions
require the bank – deposits,
withdrawals, bill payments,
revenue receipts etc.!

Purpose! For B2C and public facing apps! For B2B businesses!
Currency! Ether! None!
Mode of participation! Public/private and permissionless network! Private and permissioned network!
Consensus mechanism! Proof of work! Pluggable consensus algorithm!
Cost of operation! Every smart contract is executed globally and has
a cost for the account!
Privately controlled. No public charge.!
Programming language! Solidity! Chaincode written in Golang!
Governance! Ethereum Alliance! Linux foundation!
Transaction visibility! Everyone has total transparency! Controlled!
Performance! Poor performance and scalability! Can be scaled up easily adding
unlimited nodes!
Ease of use! Simple allows easy development of smart contracts! Complex and powerful platform!

21. In summary Ethereum is fully decentralized with each node
running the Ethereum Virtual Machine. Centralization of
computing though is forced with users having to pay a
transaction fee where they are charged for every smart contract
execution. !
Hyperledger platform is decentralized with nodes
independently executing a copy of the hyperledger fabric.
Networks have a choice of connecting to the cloud of a major
vendor such as IBM, Oracle, SAP, AWS etc to ensure network
control, governance and integrate with legacy applications.!

Blockchain Use Cases!
Mastercard Blockchain facilitates new commerce opportunities for the digital transfer of value by allowing businesses and
financial institutions to transact on a distributed ledger. Our technology can power multiple use cases and can help take
time, cost and risk out of financial flows. For example, use cases may include:!
!
Proof of provenance!
Counterfeiting costs 7 percent of global economic output, or $1.7 trillion per year, and is rising at 15 percent per annum.
Today, there is no efficient and effective way to prove that goods and services are what they claim to be and that they have
not been altered, forged, reproduced or duplicated in any way. Leverage the Mastercard Blockchain and Authorization
Network to easily track high value pharmaceuticals, art, luxury goods as they are created, transferred, purchased and re-
sold. For example, use a Mastercard plastic card with a standard payment terminal to record that the asset arrived at a
location on the Blockchain.!
!
Cross-border B2B Payments!
When two parties agree to transfer funds they write a settlement request to the Blockchain. The Mastercard Settlement
Network reads the Blockchain and will transfer the funds between two banks. It then writes a confirmation of transfer to the
Mastercard Blockchain.!
!
Mastercard Blockchain APIs!
Blockchain Core API!
Run your own blockchain nodes, define your own transaction types, and manage your participation in a blockchain network.!
Smart Contracts API!
Write custom scripts using Mastercard’s Smart Contract language for use in your custom blockchain applications.!
