Blockchain is a digital ledger of transactions that is programmed to record all types of valuable transactions in a verifiable and permanent way. It works by distributing the ledger across a network of computers that must approve transactions before they are added to the chain in blocks. This allows transactions to be recorded in a transparent yet secure manner. Blockchain has the potential to transform business by enabling applications for money transfer, taxes, micropayments, smart contracts, and more. Several companies are experimenting with blockchain technology for uses in financial services, property records, healthcare data sharing, and tracking valuable assets like diamonds.

“ Blockchain is the brainchild of a person or group of people
known by the pseudonym, Satoshi Nakamoto.”
HISTORY

5. WHAT IS BLOCKCHAIN?
“Blockchain is an incorruptible shared digital ledger of
economic transactions that can be programmed to record not
just financial transactions but virtually everything of value.” Don
Tapscott

6. DISTRIBUTED NETWORK

7. SHARED NETWORK
Like Google Docs, this network is essentially a chain of shared
computers that must all approve an exchange before it can be
verified and recorded

8. HOW BLOCKCHAIN WORKS
Transaction is
represented online as
block
Those in the
network approve
the transactions
Block is added to the
chain which provide a
transparent record of the
transaction
The Money
moves from A to
B
A wants to
send money
to B

TRANSFORM BUSINESS?

10. UNLIMITED APPLICATIONS
Almost limitless: applications from money transfer, collecting taxes
to enabling migrants to send money back to family in countries where
banking is difficult.

11. TRANSPARENCY
Providing transparency for almost
every type of transaction involving
value, including money, goods and
property

12. SECURE DATA
Secure transactions, reduced hacking

13. Open to
Micropayments

14. SMART CONTRACTS BUILT IN
Verifiable, signed & encrypted

15. TRUST
Consensus Trust improves effectiveness

16. USER CASES

17. WHO’S USING IT?
Only a very small proportion of global GDP (around 0.025%, or $20
billion) is held in the blockchain, according to a survey by the World
Economic Forum’s Global Agenda Council.
Companies racing to adapt blockchain include here in the UK,
Barclays, Bank of Ireland, UBS, Microsoft, IBM and PwC. The Bank of
Canada is also experimenting with the technology.

18. ETHEREUM
Ethereum is a decentralized platform that runs smart contracts:
applications that run exactly as programmed without any possibility
of fraud or third party interference. on a custom built blockchain
This enables developers to create markets, store registries of debts or
promises, move funds in accordance with instructions given long in
the past (like a will or a futures contract) and many other things that
have not been invented yet, all without a middle man or counterparty
risk.

19. FINANCIAL SERVICES
Low cost cross-border frictionless payments, low transaction risk,
near instant settlement, easy to use no third party. Example: Coinc.ph

20. PROPERTY
Blockchain applications can help record, track, and transfer land titles,
property deeds and helps ensure the documents are accurate and verifiable.
Example: www.Ubitquity.io

21. HEALTHCARE
Blockchains can allow hospitals and other parties in the healthcare
value-chain to share access to their networks without compromising
data security and integrity.
Example gem.co

22. RETAIL- PROVENANCE
Provenance use
digital tools power
transparent
businesses and
traceable products.
We use technology to
help us all make
purchases that are
meaningful and
more informed.

23. EVERLEDGER
global, digital ledger
that tracks and protects
valuable assets like
diamonds throughout
their lifetime journey.
