2. Introduction
Blockchain is a type of distributed leader for maintaining a permanent and
tamper-proof record of transaction data.
A blockchain functions as a decentralized database that is managed by
computers belonging to a peer-to-peer (P2P) network.
Each of the computers in the distributed network maintains a copy of the
ledger to prevent a single point of failure (SPOF) and all copies are updated
and validated simultaneously.

Current Situation
* Highly Centralized
* Time Consuming
* Transaction Fee
* No Transparency

4. Building Blocks Of Blockchain
Genesis Block
(Block 0)
Block
HASH
Data = abc
Block Hash = 7f72
Prev. Hash = 0000
Data
Prev.Hash
Valid Block
Block 1

Prev.Hash
Data = def
Block Hash = 2e82
Prev. Hash = 7f72

Invalid Block
Block 2
Data = fsdfds
Block Hash = 68a6
Prev. Hash = 3e24

Normal Nodes : Submit transactions
Mining Node : Validate transactions
and produce a hash for block and
perhaps submit the block to
propagate across the network.

6. Jargons We Deal With
BlockTime : Time taken by the network to generate a new block.
Block Hash : Each block is having unique calculated by use of previous has and
the data written into the block.
Example MD5 and SHA1 (One way encryption algorithms)
Hard Fork : When the developers cannot agree on a certain set of rules in
blockchain network they split the block chain from that point.
Example Bitcoin Cash is recently created hardfork of bitcoin.

8. Virtues That Blockchain Brought
Decentralization
Transparency
Security and Privacy Over Internet
Cost Effective
Faster Dealing

9. The Other Side of the Coin
 Its still “Technical Toy” that not many people understand
 Technical Problems are also evolving as we explore blockchain say “51%
attack”
 Blockchain size problem say “BTC 140+ GB”

10. Life Story Of Blockchain (History)

11. Cryptocurrency : Bitcoin, Etherium, Litecoin and 800+ “Something
Coin”
Smart Contracts : IFTT Contracts.
Digital Identity : Anonymous nodes prove the identity of a person
Blockchain Voting : A project (followmyvote.com) is in
development
Where We are Today With Blockchain

12.  Decentralized DNS
 Decentralized Hosting
 Decentralized Storage
 Copyrighting Images
 Healthcare
 Crowdfunding
 Banks
Where We are Going from Here(Future of Blockchain)
