Blockchain & AI
Artificial Intelligence-
driven analysis are
performed directly on
the blockchain, cross-
checking a myriad of
regulations and records
as well as supply chain
and IoT data, including
time, date stamps and
geospatial, as well as
visual information.

Other examples of blockchain
Example of an unpermissioned, public ledger:
• The first blockchain application
• Defines an unregulated shadow-currency
• Bitcoin uses public-key cryptography, in which
two cryptographic keys, one public and one
private, are generated.
• Resource intensive
Blockchains for business are generally
permissioned and private, and prioritize:
• Identity over anonymity
• Selective endorsement over proof of work
• Assets over cryptocurrency

Blockchain for business explained…..
Blockchain
for
Business
A shared,
replicated,
permissioned
ledger
14. 14
Businesses never operate in isolation. They are
participants in a Business Network.
Business Networks benefit from connectivity
• Participants are customers, suppliers,
banks, partners , etc
• Cross geography and regulatory boundary
Wealth is generated by the flow of goods
and services across business network in
transactions and contracts
Markets are central to this process:
• Public (fruit market, car auction), or
• Private (supply chain financing, bonds)
15. 15
Transferring Assets, building value…
Ownership of assets pass across the network in return for payments, and
governed by contracts.
Anything that is capable of being owned or controlled to produce value, is an asset
Two fundamental
types of asset
Intangible assets
subdivide
Cash is also
an asset
• Tangible, e.g. a house
• Intangible, e.g. a mortgage
• Financial, e.g. bond
• Intellectual, e.g. patents
• Services performed
• Digital, e.g. music
• Has property of anonymity
16. 16
Blockchain is a distributed ledger that creates a permanent and
shared record of transactions
“At its core, blockchain is a
shared ledger that allows
participants in a business
network to transact assets
where everyone has control
but no one person is in
control.”
Leanne Kemp
CEO and Founder, Everledger

18. 18
Shared ledger
Records all transactions across
business network• Shared between participants
• Participants have own copy through
replication
• Permissioned, so participants see only
appropriate transactions
• THE shared system of record
19. 19
Smart contract
Business rules associated
with the transaction
• Verifiable, signed
• Encoded in programming
language
• Example:
– Defines contractual conditions
under which a bond transfer
occurs
20. 20
Privacy
• Participants need:
– Appropriate privacy and confidentiality
between subsets of participants
– Identity not linked to a transaction
• Transactions need to be authenticated
• Cryptography is central to these
processes
The ledger is shared, but
participants require privacy and
confidentiality
21. 21
Proof
The ledger is a provable source
of information• Participants endorse transactions
– Business network decides who will
endorse transactions
– Endorsed transactions are added to the
ledger with appropriate confidentiality
• Assets have a verifiable audit trail
– Transactions cannot be modified,
inserted or deleted
• Achieved through consensus,
provenance, immutability and finality
