What is 
Blockchain?
 Blockchain technology is an advanced database  
mechanism that allows transparent information  
sharing within a business network. A blockchain  
database stores data in blocks that are linked  
together in a chain.Blockchain enables the real-time 
 recording of data about any event or transaction  
through a distributed, decentralized, peer-to-peer  
ledger that is immutable and replicated across  
numerous nodes connected by a network. It is made 
 up of links in a chain that are used to securely 
record  digital assets. A digital chain composed of  
unchangeable data blocks stored on a 
decentralized  and dispersed network of computers.
Basic Concept of 
Blockchain
What are The 4 Types 
of  Blockchain?
Public Blockchain
It is a distributed ledger that  anyone can join and use to complete transactions. Every computer in the network has a  
copy of every other node or block in the network. We can also carry out transactions or record verification. Anybody 
with  access to the internet and a computer with decent hardware can take part  in this open blockchain.
Traditional financial systems can be replaced by public blockchains because they are secured by proof of work or proof 
 of stake. The smart contract that  allowed this blockchain to support decentralization represents its more advanced 
side.
Bitcoin and Ethereum are two examples of public blockchains.
Private Blockchain
A blockchain network operates in a private setting, such as a restricted network, or is managed by a single identity. 
only  selected nodes can participate in the process, making them more secure than the others.
This blockchain, with proper security and maintenance, is a great asset for securing information without exposing it 
to  the public eye. As a result, businesses use them for internal auditing, voting, and asset management.
Hybrid Blockchain
Companies that  want the best of both worlds use a hybrid blockchain, which combines the benefits of both private 
and  public blockchains. some parts are controlled by one organization and others are made visible as a public 
blockchain.
It offers a more comprehensive solution to the healthcare industry, government, real estate, and financial firms. 
It  provides a solution when data must be accessed publicly but must be protected privately.
Consortium Blockchain
A consortium blockchain, also known as a federated blockchain, has both private and public blockchain features, 
similar  to how a hybrid blockchain does.
How 
blockchain  
works?
As each transaction occurs, it is recorded as a “block” of data
Those transactions show the movement of an asset that can be tangible (a 
product)  or intangible (intellectual). The data block can record the information of 
your choice:  who, what, when, where, how much and even the condition — such as 
the  temperature of a food shipment.
Each block is connected to the ones before and after it
These blocks form a chain of data as an asset moves from place to place or  
ownership changes hands. The blocks confirm the exact time and sequence of  
transactions, and the blocks link securely together to prevent any block from 
being  altered or a block being inserted between two existing blocks.
Transactions are blocked together in an irreversible chain: a blockchain  
Each additional block strengthens the verification of the previous block and 
hence
the entire blockchain. This renders the blockchain tamper-evident, delivering 
the key  strength of immutability. This removes the possibility of tampering by a 
malicious  actor — and builds a ledger of transactions you and other network 
members can  trust.
Benefits of 
 
blockchain
What needs to change: Operations often waste effort on duplicate record keeping and  
third-party validations. Record-keeping systems can be vulnerable to fraud and  
cyberattacks. Limited transparency can slow data verification. And with the arrival of  
IoT, transaction volumes have exploded. All of this slows business, drains the bottom 
line
— and means we need a better way. Enter blockchain.
Greater trust
With blockchain, as a member of a members-only network, you can rest assured that  you are receiving accurate and  
timely data, and that  your confidential blockchain records will be shared only with network members to whom you 
have  specifically granted access.
Greater security
Consensus on data accuracy is required from all network members, and all validated transactions are 
immutable  because they are recorded permanently. No one, not even a system administrator, can delete a 
transaction.
More efficiencies
With a distributed ledger that  is shared among members of a network, time-wasting record reconciliations are  
eliminated. And to speed transactions, a set of rules — called a smart contract — can be stored on the blockchain 
and  executed automatically.
