4. What is Blockchain Technology?
A blockchain is a distributed database or ledger
that is shared among the nodes of a computer
network. As a database, a blockchain stores
information electronically in digital format.
Blockchains are best known for their crucial
role in cryptocurrency systems, such as Bitcoin,
for maintaining a secure and decentralized
record of transactions. The innovation with a
blockchain is that it guarantees the fidelity and
security of a record of data and generates trust
without the need for a trusted third party.

5. Fundamentals of Blockchain
1. Public Distributed Ledgers
• A blockchain is a decentralized public distributed ledger that is used to record transactions
across many computers.
• A distributed ledger is a database that is shared among the users of the blockchain
network.
• The transactions are accessed and verified by users associated with the bitcoin network,
thereby making it less prone to cyberattack.
2. Encryption
• Blockchain eliminates unauthorized access by using the cryptographic algorithm (SHA256)
to ensure the blocks are kept secure.
• Each user in the blockchain has their key.

6. 3. Proof of Work
Proof of work (PoW) is a method to validate transactions in a blockchain network
by solving a complex mathematical puzzle called mining.
Note: Users trying to solve the puzzle are called miners.
4. Mining
In Blockchain, when miners use their resources (time, money, electricity, etc.) to
validate a new transaction and record them on the public ledger, they are given a
reward.
Note: As a reward, the miner gets 12.5 BTC (bitcoins)

7. Introduction To Connected Vehicle
Information Network
1.Connected Vehicles: This term generally refers to vehicles equipped with
internet connectivity and communication technologies. These vehicles can
exchange data with other vehicles, infrastructure, and cloud-based services to
enhance safety, efficiency, and the overall driving experience.
2.Information Network: This might suggest a network or system that collects,
processes, and disseminates information related to connected vehicles. Such a
network could involve data from various sources, including vehicle sensors,
traffic management systems, and user devices.

8. How Does CVIN Work?
Vehicle Connectivity: Connected vehicles are equipped with various sensors, communication modules, and
onboard computers. These components enable the vehicle to collect data about its own operation, location, and
environment.
Data Collection: The connected vehicle continuously collects data from its sensors, which can include information
about speed, location, acceleration, braking, engine performance, and more. Some vehicles may also have
cameras and other sensors to capture visual and environmental data.
Data Processing: The data collected by the vehicle's sensors are processed locally within the vehicle's onboard
computer. This processing can involve aggregating and formatting the data for transmission.
Communication: The vehicle uses its communication module (often cellular or Wi-Fi) to transmit the processed
data to a central server or cloud-based platform. The data can also be exchanged with other nearby vehicles
(Vehicle-to-Vehicle or V2V communication) or with roadside infrastructure (Vehicle-to-Infrastructure or V2I
communication).

9. Information Dissemination: Once the data is processed and analyzed, relevant
information is sent back to connected vehicles and, in some cases, to traffic management
centers, transportation agencies, and navigation systems. This information can include
real-time traffic updates, road closures, weather conditions, and more.
User Interface: The information is presented to drivers through user interfaces such as in-
car displays, mobile apps, or navigation systems. Drivers can receive alerts, navigation
guidance, and other information to improve their driving experience and safety.
Applications and Services: Various applications and services can be built on top of the
CVIN, such as traffic management, predictive maintenance for vehicles, remote
diagnostics, emergency services coordination, and more.

11. V2V (Vehicle-to-Vehicle) Communication
V2V, which stands for Vehicle-to-Vehicle communication, is
a crucial component of a Connected Vehicle Information
Network (CVIN). It refers to the capability of vehicles to
communicate directly with other nearby vehicles on the
road. V2V communication allows vehicles to exchange
information about their speed, location, direction, and
other relevant data in real-time. One of the primary
purposes of V2V communication is to enhance road safety.
By sharing information about their positions and
movements, vehicles can help each other avoid collisions
and potentially dangerous situations. For example, if a
vehicle detects that another vehicle is rapidly approaching
an intersection without stopping, it can send a warning to
nearby vehicles.

12. V2I, or Vehicle-to-Infrastructure
communication, is another important
component of a Connected Vehicle
Information Network (CVIN). V2I
communication involves the exchange of data
between vehicles and roadside infrastructure
such as traffic lights, signs, sensors, and
other infrastructure elements. V2I
communication plays a vital role in traffic
management and optimization. Infrastructure
elements can provide data on traffic flow,
congestion, and road conditions to connected
vehicles. In turn, vehicles can send data to
the infrastructure to provide information on
their location, speed, and traffic behavior.

14. CVIN vs. Blockchain
Immutable Data Records: Blockchain can be used
to create a tamper-proof ledger of all data
transactions within the CVIN. This ensures that
data related to vehicle-to-vehicle (V2V) and
vehicle-to-infrastructure (V2I) communication,
traffic data, and other information remains
unchanged and trustworthy.
Data Encryption: Blockchain networks often
implement robust encryption methods to secure
data. This is crucial for protecting sensitive
information exchanged within the CVIN, such as
location data and personal information.

15. 1.Collision Avoidance: CVINs enable real-time communication between vehicles, allowing for collision
avoidance systems to warn drivers and take autonomous actions to prevent accidents.
2.Emergency Services: In the event of an accident, CVINs can automatically transmit critical data to
emergency services, reducing response times and potentially saving lives.
3.Dynamic Routing: CVINs offer drivers real-time information on traffic conditions, road closures, and
alternative routes, allowing for more efficient navigation.
4.Fuel Efficiency: Reduced idling and smoother traffic flow through CVINs contribute to fuel efficiency,
lowering fuel consumption and emissions.
5.Automatic Crash Notification: CVINs transmit data about accidents to emergency services, facilitating
quicker response times for first responders.
6. Urban Planning: CVIN data informs urban planners about traffic patterns, congestion hotspots, and
infrastructure needs, contributing to more efficient and sustainable city development.

16. 1.Privacy Concerns: CVINs collect a vast amount of data, including location and driving behavior, raising
concerns about the privacy of individuals. Unauthorized access or misuse of this data can be a significant
issue.
2.Cybersecurity Risks: CVINs are vulnerable to cyberattacks, including hacking, data breaches, and
malware. A breach in the network's security can compromise the safety and privacy of connected vehicles
and their occupants.
3.Infrastructure Costs: Building and maintaining the necessary infrastructure for CVINs, including roadside
sensors and communication equipment, can be costly. Smaller municipalities may struggle to afford these
investments.
