Blockchain is a secure digital ledger that eliminates the need for a central authority and has many applications. Using blockchain requires defining a problem, choosing a platform, developing a smart contract, creating a network, integrating an application, testing, deploying, and maintaining/updating. Expertise may be needed. Blockchain offers benefits such as decentralized control, security, transparency, efficiency, traceability, and the ability to automate complex transactions with smart contracts. It can be used in various industries to enhance security, efficiency, and transparency. Blockchain advantages: Decentralization, security, transparency, efficiency, traceability, and smart contracts. These make it an attractive solution for various industries like finance, supply chain management, healthcare that need enhanced security and transparency. https://login360.in/courses/blockchain-training-in-chennai/

2. Introduction
Recently, there has been a lot of interest in the innovative
invention known as blockchain technology.
It is a digital ledger that securely logs and authenticates
data or transactions that is decentralised and open-source.
Blockchain-based peer-to-peer transactions are efficient
and secure since they do not need middlemen.
Thanks to its potential to completely transform a variety
of industries, blockchain holds out the promise of greater
transparency, trust, and efficiency in the digital age.

3. Blockchain is a decentralised, open-source digital
ledger technology that logs transactions and other data
securely and impenetrably.
It eliminates the need for a centralised authority and
offers increased security and trust for a variety of
applications.
What is blockchain

4. How it's working
Blockchain is powered by a decentralised computer
network that controls a central ledger.
Collections of transactions or data are grouped together
as blocks, each of which has a unique hash and a
reference to the block preceding it.
Consensus procedures validate and verify blocks before
they are added to the chain in order to preserve
immutability and security.

5. Who invented blockchain
An unidentified person or group called Satoshi
Nakamoto developed the blockchain technology.
The Bitcoin whitepaper, which introduced the
blockchain concept for a peer-to-peer electronic
payment system, was published in 2008 by
Nakamoto.
Both technology and money have been
significantly impacted by Nakamoto's contribution.

6. How developed the blockchain
Unknown person or group Satoshi Nakamoto
invented the blockchain technology.
Nakamoto was the author of the 2008 Bitcoin
whitepaper, which introduced the idea of a
decentralised digital currency and the blockchain.
Since then, the innovation of Nakamoto has been
enhanced and expanded by a global community,
resulting in its widespread adoption and application
in a variety of industries.

7. Where it is used
Globally, a wide range of businesses use blockchain
technology.
It can be used in cryptocurrencies, finance, healthcare,
and supply chain management.
It may also be used in the fields of real estate,
intellectual property, energy, and others.
Due to its transparency and security, many processes
gain from greater efficiency, traceability, and
confidence.

8. Conclusion
In conclusion, blockchain technology has the ability to
fundamentally alter a range of industries because it is
open, safe, and decentralised.
With applications in finance, healthcare, supply chain
management, and more, it promotes enhanced efficiency
and trust.
As the technology advances, it still has a lot of room for
innovation and disruption.
