3. What is Blockchain?
Popularized
Concept of Block
Transparency
Introduced in 2008 with the
concept of Bitcoin.
Cryptographically signed
transactions grouped into blocks.
Designed to provide
transparency, security, and trust
between participants in a system.
Blockchain is defined as a tamper-
evident and tamper-resistant digital
ledger that records transactions in a
decentralized fashion, meaning it
operates without a central repository
or authority like a bank or
government. Transactions are
grouped into blocks, cryptographically
linked to previous ones, creating a
secure, immutable chain.

4. Decentralization
No Central Authority
Distributed Nodes
Enhanced Security
Operates without intermediaries.
Every node in the network
maintains a copy of the
blockchain, ensuring redundancy.
Decentralization minimizes risks
of failure or control from a single
point.
Decentralization in blockchain refers
to the distributed nature of its
architecture. Instead of being
managed by a single entity, control
and decision-making are shared
among participants in the network.

5. Distributed Ledger
Transparency
Resilience
Cryptographic Security
All participants have access to the
same data, fostering trust.
Multiple copies ensure data
persistence and protection
against loss or tampering.
Transactions are validated and
linked using cryptographic
methods, ensuring integrity.
A distributed ledger is the
fundamental architecture of
blockchain where the ledger (record
of transactions) is shared and
synchronized across multiple nodes in
the network.

6. Enhancing Supply Chain Visibility Real-Time Visibility
Preventing Fraud Future of Blockchain in SCM
Blockchain improves supply
chains by making them more
transparent, trackable, and
secure, ensuring that every
transaction is trustworthy and
can't be changed.
Enables tracking of goods across
the supply chain, ensuring
product quality, authenticity, and
timely delivery, while reducing
inefficiencies.
Blockchain keeps data secure and
unchangeable, preventing fraud
and ensuring honesty in
operations.
Integrating blockchain with IoT
and cloud computing will
enhance scalability,
interoperability, and cross-
industry collaboration, making
supply chains more efficient.

7. Maersk’s TradeLens
Improved shipping by
allowing real-time data
sharing, reducing delays, and
making communication more
transparent.
Walmart:
Walmart uses Hyperledger
Fabric blockchain to
securely track products in
its supply chain, improving
traceability, safety, and
accountability.

8. Impact on Remittance Costs &
Time:
Enhancing Remittance with
Crypto Wallets:
Reduce the cost of
remittances?
Future Opportunities for
Blockchain in Remittance:
Blockchain addresses high costs
and slow transaction times in the
remittance industry by offering
faster, secure, and decentralized
value transfers.
Blockchain enables transactions
using only crypto wallets,
reducing settlement times
through rapid block
confirmations.
Blockchain reduces remittance
costs by eliminating
intermediaries, enabling direct
peer-to-peer transfers with lower
fees and faster processing times.
Blockchain creates opportunities
such as issuing stablecoins,
removing middlemen in currency
exchange, and developing new
business ideas in the remittance
industry.
Harness The Power Of Blockchain In
Remittance Industry

9. Stellar:
Stellar blockchain helps cut
down remittance fees and
transaction time by working
with financial and nonprofit
partners for global money
transfers.
Ripple:
Ripple's blockchain technology
enables faster and cheaper cross-
border payments, which has been
adopted by various financial
institutions for remittance
services.
