Explain BlockChain technology Transactions
You can describe BLOCKCHAIN
technology as a chain containing
information from blocks. The technique is designed to time stamp digital
documents in such a way that they can not be backdated or tempered.
Blockchain's purpose is to solve the problem of double records without needing
a central server.

The blockchain is used for secure
transfer of items such as money, property, contracts, etc. without requiring an
intermediary of a third party such as bank or government. When data is recorded
inside a blockchain, it's very hard to change it.
The blockchain is a protocol to
the applications (like SMTP for email). But without the Internet, Blockchains
could not be run. It is also called meta-technology, since other technologies
are affected. It consists of several pieces: a database, application software,
some related computers, etc.
Process of Blockchain
technology Transactions
Blockchain technology is a
digital ledger that records all transactions occurring on a peer-to - peer
network. All information transferred via Blockchain is encrypted and every
occurrence is recorded, making it impossible to alter the information. As a
decentralized network, no central or certifying authority is required by the
Blockchain networks. Because of this, these networks can be relied on for much
more than currency transfer; in fact, contracts, records and other types of
data can be shared across the Blockchain network. Encrypted information can be
exchanged between different providers without risking a violation of privacy.
Blockchain has become immensely
popular due to these attributes.
• Blockchain networks are
internet distributed ledgers.
• Each action is visible to all;
only lines can be added, and also after consensus.
• 'Peer to peer': No third party
is required to complete transactions.
• Unbreakable cryptographic
hashing guaranteed.
Step 1)
Somebody asks for a transaction,
Crypto-currency, contracts, documents or other details may be part of the
transaction.
Step 2)
With the aid of
nodes, the requested transaction is transmitted to a P2P network.
Step 3)
With the help of known algorithms the node
network validates the transaction and the user status.
Step 4)
The new block is then added to
the existing blockchain once the transaction is complete. That is permanent and
inalterable in such a way.
Need for Blockchain
technology transactions
Here are some reasons why the
technology of Blockchain transactions has become so popular.
Resilience:
Blockchain are often
architectural replications. Most nodes still operate the chain in case of a
massive assault on the system.
Time reduction:
In the financial sector,
blockchain can play a vital role by allowing quicker trading settlement, as it
does not entail a lengthy authentication, settlement and clearance process
since a single version of agreed-upon share ledger data is available for all
stakeholders.
Reliability:
Blockchain certifies the
identities of interested parties and verifies them. This removes double
records, lowers the rates and speeds up transactions.
Unchangeable
transactions:
Blockchain certifies the
unchangeability of all operations by registering transactions in chronological
order, which means that it cannot be removed or modified when any new block has
been added to the ledger chain.
Prevention of fraud:
You can share the information and
consensus concepts to prevent potential losses due to fraud or
misappropriation. As a monitoring mechanism in logistics-based industries,
blockchain acts to reduce costs.
Security:
Attacking a traditional database
means bringing a specific target down. Each party holds a copy of the original
chain with the help of Distributed Ledger Technology so the system remains
operational, even with the large number of other nodes falling.
Transparency:
Updates to public blockchains are
available to everyone. This gives more transparency and all transactions are
unchangeable.
Collaboration
It allows the parties to work
directly with each other without the need for third party mediation.
Decentralized:
Standards are in place on how
each node shares information on blockchain. This method ensures authentication
of all transactions, by adding all valid transactions one by one.
Versions of Blockchain
technology
Blockchain 1.0: Devise
The DLT (distributed ledger
technology) implementation led to its first and obvious application:
cryptocurrencies. This allows for Blockchain technology-based financial
transactions. It is used in payments and in currencies. The most prominent
example in this segment is Bitcoin.
Blockchain 2.0: Smart
Transactions
The new key concepts in the
blockchain are Smart Contracts, small computer programs that "run."
They are free computer programs that automatically execute and test earlier
specified conditions such as facilitation, verification of compliance. This
serves as a substitute for conventional contracts.
DApps: Blockchain 3.0
DApps is an abbreviation for
decentralized use. It has their backend code running on a peer-to - peer open
network. A DApp can have frontend code and user interfaces written in any
language, like conventional Apps, that can make a call to its backend.
Variants to blockchain
technology
PEOPLE:
Ledgers are available to everyone
on the internet in this form of blockchains. It lets anyone search the
blockchain and add a block of transactions. Public networks have incentives to
join and are free for use. Anyone could use a network of public blockchains.
Domestic:
In a single organization, the
private blockchain is in. It allows checking and attaching transaction blocks
only to unique individuals of the organization. All on the internet, however,
are usually allowed to access.
Consortium:
Within this Blockchain type,
transactions can only be checked and implemented by a group of organisations.
The ledger can be opened here, or limited to select groups. Cross-organisation
consortium blockchain is used. It's controlled only through pre-authorized
nodes.
Real-life use cases in
Blockchain technology
1.Dubai: The Trendy City
Blockchain strategy was
introduced by smart Dubai office in the year 2016. Entrepreneurs and businesses
using this technology will be able to connect with investors and leading
companies. The aim is to implement a blockchain base system that favors the
development of different types of industries to make Dubai 'the happiest city
in the world.'
2. Keeping Incent
Customer
Incent is the Blockchain-based
CRaaS (Consumer Retention as a Service). It is a loyalty program based on
generating token for business that is affiliated with its associated network.
Blockchain is exchanged instantly in this method, and it can be stored in
user's phone digital portfolios or accessed via browser.
3. Humanitarian Aid
Blockchain
This is a project called
humanitarian aid that was initiated by the United Nations world food programme.
The project was being developed in rural areas of Pakistan's Sindh region.
Using the Blockchain technology, beneficiaries receive money, food and all
types of transactions are registered on a blockchain to ensure that this
process is safe and transparent.
Limitations of
Blockchain technology Transactions
Higher costs:
Nodes pursue higher incentives
for completing transactions in a company that operates on the supply and demand
principle.
Slower transactions:
Nodes prioritize higher-reward
transactions, transaction backlogs build up
Smaller ledger:
A full copy of the Blockchain is not feasible,
potentially affecting the immutability, consensus, etc.
Transaction costs, network speed:
Bitcoin's transaction costs are quite high after being proclaimed 'nearly free'
in the first few years.
Risk of error:
As long as the human factor is involved there is always a risk of error. In the
event that blockchain functions as a database, all incoming data must be of
high quality. Human involvement, though, can resolve the error quickly.
Wasteful:
Any node running the blockchain
has to keep consensus across the blockchain. This offers very low downtime and
makes the data stored on the blockchain un-changeable forever. All this,
however, is inefficient, since each node repeats a task to reach consensus.
