3. INTRODUCTION
Blockchain technology is a revolutionary concept that has the
potential to transform various industries. It is essentially a
decentralized, distributed ledger that records transactions in a
secure and transparent manner.
The beauty of blockchain technology lies in its ability to eliminate
the need for intermediaries in transactions. This means that
parties can transact directly with each other without the need for
a middleman such as a bank or government institution. This not
only reduces costs but also enhances efficiency and security

1. Bitcoin
The primary application of Blockchain
is in Cryptocurrencies like Bitcoin.
Bitcoin is a decentralized digital
currency introduced by Santoshi
Nakamoto.
2. Banking :
Nowadays, Blockchain is also
replacing the existing, or we can say
overtaking the current Banking
system. With the help of Blockchain,
we can transfer the fund from one
person to another in a second
because the transaction’s validation
will take place through Blockchain and

2. Government:
Governments can start implementing distributed ledger
technology (DLT) systems to replace traditional paper-based
systems.
3. Finance – Banking:
El Salvador adopted Bitcoin as legal tender in 2021, possibly
because of global inflation and high costs of financial
intermediaries. Cryptocurrencies may soon be accepted by
developing nations, according to experts.
1. Cybersecurity:
Data tampering is a challenge for businesses today. Blockchain is a promising area for cybersecurity growth. It
secures data, prevents tampering, and allows file authenticity verification.

11. WE BELIEVE THAT BLOCKCHAIN TECHNOLOGY WILL HAVE
MANY TRANSFORMATIONS IN THE TECHNOLOGY AND IT
SECTORS IN THE COMING YEARS, SIMILAR TO WHAT THE
INTERNET DID TO THE WORLD IN THE 90S AND THE EARLY
2000S”. THUS, BLOCKCHAIN WILL BE INCREASINGLY
IMPROVED IN THE FIELD OF TECHNOLOGY AND APPLIED
MORE DEEPLY IN A VARIETY OF FIELDS AND INDUSTRIES.

12. SUMMARY
Presentation title 12
A blockchain is a decentralized,
distributed and public digital ledger that is
used to record transactions across many
computers so that the record cannot be
altered retroactively without the alteration
of all subsequent blocks and the
consensus of the network.
