Blockchain technology has emerged as a potentially disruptive technology built around the concept of a distributed consensus ledger maintained on a distributed network. A blockchain allows for a digital ledger of transactions to be created and shared on a distributed network without a central authority by using cryptography. Key elements include the distributed nature of the ledger based on an agreed consensus mechanism, which allows for near real-time automated transactions with strong fraud controls.

2. Over the last few years, a major IT
innovation known as blockchain
technology has emerged as a
potentially disruptive technology.
The core of this innovation is built
around the concept of a
distributed consensus ledger,
where the ledger is kept and
maintained on a distributed
network of computers.

3. A blockchain is a data structure that
makes it possible to create a digital
ledger of transactions and share it
among a distributed network of
computers. It uses cryptography to
allow each participant on the network
to manipulate the ledger in a secure
way without the need for a central
authority.

5. The key elements of a
blockchain-based ledger is
distributed nature of the
ledger base on the existence
of an agreed-upon consensus
mechanism. These make it
possible to automate
transactions, providing for
close to real-time settlement,
while maintaining strong
controls against fraud.

7. Use Case: Payments through Bitcoin
• Bitcoin is a digital currency created in 2009
by an unknown person using the
alias Satoshi Nakamoto. It can be used to
buy or sell items from people and
companies that accept bitcoin as payment
using Blockchain Technology.
• How to get Bitcoin :
 Buying or Selling through websites like
Coinbase,Zebpay
 Mining :By using computers to solve complex
math puzzles.
• Bitcoin / USD exchange rate:
 July 17, 2010 1 Bitcoin = $0.05
 October,25 2018 1 Bitcoin = $6,393.76

8. Use Case: Smart Contracts

9. Use Case: Online Identity Management

10. Benefits
1. Trustworthy system
2. Transparency
3. Faster transactions
4. Reduced transaction costs

11. Challenges
1. Cost of Initiation, Implementation,
and Maintenance
2. Modifications of Data
3. Literacy Requirements
4. Blockchain Regulations
5. Dependability on Computers
