Blockchain technology is a digital innovation that can significantly impact financial markets in the next few years. It allows for trustworthy and secure transactions through a distributed ledger maintained across a peer-to-peer network. A blockchain uses cryptography to record transactions in blocks that are chained together, making past records unalterable. While still developing, blockchain offers opportunities for trust and security across industries through features like smart contracts and distributed data storage. It remains to be seen how widely blockchain will be adopted and what applications may emerge in the future.

2. BLOCK CHAIN TECHNOLOGY
•Overview
•Development
•Working
•Future Applications

3. PARTICIPANT EXPOSURE!
How many of you :
• Have Heard of Cryptocurrency?
(Like Bitcoin,Etherum,Litecoin,Ripple)
• Did You ever felt like having your own
Cryptos?
• Have you ever thought of involving in Projects
based on Block Chain Technology?

4. BLOCK CHAIN OVERVIEW
• Block Chain Technology is a Digital
Innovation that is having an ability to
significantly Alter financial markets
within the next few years , that has
Potential to be trust worthy and
improve Cyber Security Systems.

5. WHAT IS ACTUALLY BLOCK CHAIN?

7. EVOLUTION OF BLOCK CHAIN

8. A Digital timestamp is the time
at which an event is recorded
by a computer.

9. In year 2008, an individual or group
writing under the name of “Satoshi
Nakamoto” published a paper
entitled “Bitcoin: A Peer-To-Peer
Electronic Cash System”

10. 2008
• August 18 Domain name
"bitcoin.org" registered
• November 09 ​Bitcoin
project registered at
SourceForge.net

11. 2009
• January 3 Genesis block
established.
• January 9 Bitcoin v0.1 released and
announced on the cryptography list.
• January 12 First Bitcoin transaction,
in block 170 from Satoshi to Hal
Finney.

12. Bitcoin is a cryptocurrency and
worldwide payment system.It is
the first decentralized digital
currency.

13. Coming back to what is Block Chain?

14. A Distributed Ledger is a database that is shared
across network and spread across multiple sites such
as Institutions

15. FRONT END:
HTML-Creating Webpages.
CSS-To add colors and graphics to it.
JAVA SCRIPT-To design interactive
windows etc.

16. BACK END:
C++, Golang and Python- for Coding
Database-Block Chain itself is a
Distributed Ledger database

21. Consider a Chain of 3 Blocks

22. Matching of Hash Code to Previous Block

24. Suppose in case of Intruder Activity

25. Changes occur to the affected block’s
Hash Code

27. WHO SAID HASH CODE
CANT BE CRACKED???

29. In Such Cases,
Block Chain Developers have
come up with another idea.

30. That is
Peer to Peer
Network

32. A chain of 3 blocks are considered

34. Adding of New Authentic Block to the Block Chain

35. All the P2P users are in
agreement with the new
Block addition

36. In Addition to this,Block Chain users
have their own Private Key and Public
Key.
Public Key is Known to every one and
Private Key is the “Decrypt of Hash
Code and Respective Address of the
Block”.

38. Medical reports of
high profile are sent
through block chain
E-notary are
digitally signed to
avoid breach of data
Few Countries
have started
collecting taxes

39. PRESENT SCENARIO
Block Chain Technology is so influential
that even our Indian Entrepreneur
have started working on India’s First
Cryptocurrency LAXMI Coin that is
going to be launched by this
February for which I am eagerly
Waiting to Invest!

40. FUTURE USES:
•Stock Market Trading
•Multiple Transactions
•Smart Contracts : It is a computer
protocol intended to digitally verify the
performance of a contract.
•File Storage

41. IMPACT ON SOCIETY
•Although this Technology is still in development (ie) in
Starting Stages Boundless Opportunities exist.
•Features that could create Trust Achievable to every
industry.
•Burden on Security systems will be reduced but this may
still take to implement.
•IOT projects can also be developed using this Tech.

42. STILL DOUBT HOW SECURE THE
BLOCK CHAIN TRANSACTION IS ?

43. WHAT WOULD BE RUNNING IN A
HACKERS MIND?
Hack Something Which
Either Gives Him Fame Or
Money
And
Never Get Caught..!!!

44. MAY 2017
WANNACRY RANSOMWARE ATTACK
This was a worldwide CyberAttack by the
WannaCry Cryptoworm, which targeted
computers running the Microsoft
Windows operating system by Encrypting data
and demanding payments in
the Bitcoin cryptocurrency, So that they cant be
tracked through Transactions…!!

46. Very Secure
Right??

47. Though This wasn’t a good
sign towards development
of Technology and a Total
Misuse of both Time and
Skill.

48. CONCLUSION
To Conclude
There is enormous interest in
BlockChain based business applications
and hence numerous Start-ups working
on them.
So now its time to think about future
plan on how to adopt this new
technology!

49. Thank You….!!!!!
