3. What isblockchain?
Blockchain is basically a chain like
structure in which each block
stores all the transactional details
and records of the owner. This
storage structure is referred to as
6Digital ledger7.

5. Why blockchain?
In digital transactions blockchain brings a trust,
transparency and accountability. If a system built
on the blockchain will not take much time to
process transactions and it also requires many
more times the resources like processing,
electricity and data transfer.
6. Blockchain is an open distributed ledger which can
record transactions safely in a efficient way. It is
distributed so it is typically managed by a peer-to-
peer network which is working together to solve many
complex mathematical problem in order to validate
fresh blocks.

APPLICATIONS OF BLOCKCHAIN:
9. A cryptocurrency is a digital or virtual
currency that is secured by cryptography,
which makes it nearly impossible to
counterfeit or double-spend. Many
cryptocurrencies are decentralized networks
based on blockchain technology—
a distributed ledger enforced by a disparate
network of computers. A defining feature of
cryptocurrencies is that they are generally not
issued by any central authority, rendering
them theoretically immune to government
interference or manipulation.
CRYPT OCURRENCIES:
10. Cryptocurrencies are basically designed to behave as
medium of exchange which is created and stored
electronically in blockchain.Blockchain cryptocurrencies
works on digital channels and they are sticked to strong
cryptography to secure financial transaction which
occur through online.
Several types of blockchain cryptocurrencies are
Bitcoin, Litecoin, Ripple etc.
Due to this Blockchain currency it became possible to
create things that is not possible to be duplicated and it
can sent easily and directly from one person to the
another.
The value and the supply of cryptocurrencies are
controlled by the activities of their users and highly
complexed protocols which are built into governing
codes.
Blockchain Cryptocurrencies:
11. Blockchain and Cryptocurrency
are not same
Blockchain currency is referred to the online mode of
transactions and blockchain is the technology underlying it.
Blockchain drives the concept of cryptocurrency as the
whole. The note is that the Blockchain was basically
designed to manage the crypto currencies. Blockchain
stores all the data on a distributed ledger in which all the
transactional details for every activity is stored and
maintained . Cryptocurrency is another type of data
which can be stored on a blockchain.
How Blockchain is used in
Cryptocurrency?
Blockchain allows Cryptocurrencies to operate without the
need of the central authority by spreading its operation across
a network of computers. This reduces risks and also eliminates
the processing and transaction fees of many.
13. Decentralization
In blockchain, decentralization refers to the transfer of control
and decision-making from a centralized entity (individual or
group of organization) to a distributed network.
Why Decentralization ?
When building a technology solution, three primary network
architectures are typically considered centralized, distributed,
and decentralized.
While blockchain technologies often make use of
decentralized networks, a blockchain application itself cannot
be categorized simply as being decentralized or not. Rather,
decentralization is a sliding scale and should be applied to all
aspects of a blockchain application. By
decentralizing the management of and access to resources in
an application, greater and fairer service can be achieved.
14. TRANSPARENCY:
TRANSPARENCY IN REAL LIFE MEANS SOMETHING WITH ZERO OPACITY.
In Blockchain, it means that blockchain has zero privacy to
be exact when we talk about transactions, all the transactions
are public and can be viewed by anyone on the network.
One area where blockchain technology truly shows off its
transparency is through Bitcoin casino sites. While in any
casino, the house will always have the advantage, provably
fair games allow users to actually check the server seeds of
the game to ensure that the results they are receiving are
genuine and fair. This is a truly revolutionary aspect to online
gaming and is something that other casino sites and gaming
platforms are looking at integrating in order to develop a new
level of trust between the site and their players.
15. Immutability:
Immutability can be defined as the ability of a blockchain
ledger to remain unchanged, for a blockchain to remain
unaltered and indelible. Data in the blockchain cannot be
altered.
Each block of information, such as facts or transaction
details, proceed using a cryptographic principle or a hash
value. That hash value consists of an alphanumeric string
generated by each block separately. Every block not only
contains a hash or digital signature for itself but also for the
previous one. This ensures that blocks are retroactively
coupled together and unrelenting. This functionality of
blockchain technology ensures that no one can intrude in the
system or alter the data saved to the block.
16. Prerequisite Skills Required to be a Blockchain Developer
Fundamental skill and Knowledge in
Technical Field
There are a few skills that one should learn to become a blockchain developer.
An individual should have a good knowledge of Information technologies,
Information security, and computer science. The basic understanding of an
aspiring blockchain developer should be clear in distributed systems,
networking, cryptography and data structures.
WHO CAN LEARN
BLOCKCHAIN?
17. Append only . Validated transactions.
Once information is recorded it cannot be reversed or
changed.
Before blocks are recorded,transactions must be validated.
Data stored on
private keys
Reliable security.
blockchain can only be accessed with
Empowered users : users are in control of all the
information and transactions.
High quality data : blockchain data is complete consistent
timely accurate and widely available..
ADVANT AGES:
18. Human error.
If used as a database information must be of immense
quality.
Many governments are still exploring the need for
blockchain.
Lack of full-scale adoption. Uncertain regulatory status.
Businesses worldwide are still unsure about adopting
blockchain.
Data immutable: Blockchain cannot go back as as data is
immutable.
Integration : Its hard to integrate into Legacy systems.
DISADVANT AGES:
