2. Blockchain is a decentralized ledger of all transactions across a
peer-to-peer network. using this technology , participants can
perform transactions without the need for a central certifying
authority. Potential applications include fund transfers , settling
trades , voting and manyothers.
Business Networks benefit from connectivity – Connected
customers, suppliers, banks, partners.
Wealth is generated by the flow of goods & services across
business network.
Anything that is capable of being owned or controlled to
produce value, is an asset.
Two fundamental types of asset – Tangible, e.g. a house –
Intangiblee.g. a mortgage.

3. HOW TRANSACTIONS ARE DONE?

4. 1. is unregulated, censorship-resistant shadowcurrency.
2. Blockchain ensures “cash like” coin passing
•unique,
•immutable,
•Final.
3. Bitcoin is the first Blockchain application.
4. Digital currencies different from cyptocurrency.

5. BitPesa
It is adigital foreignexchangeand paymentplatform for
frontier markets.
Storj
It is a crypto currency and digital paymentsystem and is also
a blockchain-based digital storageand data retrieval method.
Riot Blockchain
Formerlya biotech companycalled Bioptix, thecompany
rebranded and is now listed on the NASDAQ exchange under
ticker symbol RIOT, making it the first purely Blockchain
focused public US stock.

6. Golem
Golem is a global, open source, decentralized supercomputer
thatanyonecan access. It is made upof the combined powerof
users’ machines, from PCs toentiredatacenters.
Open Bazaar
It is one of the first marketplaces that accepts cryptocurrency
for transactions. Think of it like a hybrid of eBay and Etsy that
runson cryptocurrency and charges no fees.
Chronicled
The coolest featuresallow for bettersupply chain control and
managementand anti-fraud opportunities to protect brand
integrityaround theworld.

7. Transparency
Users or developers have the opportunity to
modify itas they see fit. This makes blockchain a
particularly secure technology.
Reduced transactioncosts
Blockchain allows peer-to-peer and business-to-
business transactions to becompleted without the
need fora third party. it means theycan actually
reducecosts to the useror businesses overtime.

8. Faster transaction settlements
Blockchain technology is working 24 hoursa day,
seven days a week, meaning blockchain-based
transactions processconsiderably morequickly.
Decentralization
Blockchain actually allows individual
transactions to have theirown proof of validity
and the authorization to enforce those
constraints.

9. User-controlled networks
Rather than having a third party run the show, users
and developers are the ones whoget to call the shots.

10. Smart Contracts
The Project is a decentralized platform that runs smart
contracts: applications that run exactly as programmed
without any possibilityof downtime, censorship, fraud or
third party interference.
Cloud Storage
Simply using excess hard drive space, users could store
the traditional cloud 300 timesover.

11. Supply-Chain Communications & Proof-of-
Provenance
Most of the things we buy aren’t made by a single entity, but by a
chain of suppliers who sell theircomponents (e.g., graphite for
pencils) to a company that assembles and markets the final
product.
Paying Employees
payments madevia Bitcoin can save both moneyand time for
employersand employees.
 ElectronicVoting
Delegated Proof of Stake (DPOS) is the fastest, mostefficient, most
decentralized, and most flexible consensus model available.

12. Blockchain isa shared, replicated ledger.
IBM supportsan open standards, open source, open
governance Blockchain.
Blockchain can open up business networks by taking out
cost, improving efficienciesand increase accessibility.
Blockchain addressesan exciting and topical set of
businesschallenges, which cross every industry.
