2. Abstract
Blockchain is a system of recording
information in a way that makes it difficult or
impossible to change, hack, or cheat the
system. A blockchain is essentially a digital
ledger of transactions that is duplicated and
distributed across the entire network of
computer systems on the blockchai

3. CENTRALIZED SYSTEM
• Centralized systems are
systems that use
client/server architecture
where one or more client
nodes are directly
connected to a central
server.

4. BLOCK CHAIN
• Blockchain is a
system of recording
information in a
way that makes it
difficult or
impossible to
change, hack, or
cheat the system.

5. GENERAL LEDGER
• A general ledger, is a
bookkeeping ledger in
which accounting data is
posted from journals and
aggregated from
subledgers, such as
accounts payable,
accounts receivable, cash
management, fixed assets,
purchasing and projects.

6. DISTRIBUTED LEDGER
• Distributed ledger
technology (DLT) is a
digital system for
recording the
transaction of assets
in which the
transactions and their
details are recorded in
multiple places at the
same time.

7. BENEFIT OF BLOCK CHAIN
• As there is no Intermediate third
party in between the transaction, it
can widely help in many ways like,
no service charges, the processing
time is reduced and many more
benefits can be attained

8. WHY IT IS CALLED BLOCK CHAIN
• Blockchain owes its name
to the way it stores
transaction data—in blocks
linked together to form a
chain. As the number of
transactions grows, so does
the blockchain.

9. HOW DOES IT WORK?
HashValue is a combination of
alphabet and numbers that are
assigned with the information
about the transaction details
given. These HashValue can’t
be changed. If they are
attempted to be changed the
will be rejected by the
distributed system

10. HOW DOES IT WORK
Each block contain the
it, hashvalue of
Previou block which
thus form a chain, by
attempting to include
another block
inbetween it, 2 blocks
the continuity breaks,
and the changes is
rejected

12. Conclusion
• Smart contracts
are simply
programs stored
on a blockchain
that run when
predetermined
conditions are
met.

Is there anything doubts??
