Slide 4

This slide illustrates the multiple types of blockchain such as public, private, consortium, and hybrid.

Slide 5

This slide illustrates the concept of public blockchain technology. It also provides information regarding the definition and examples of the public blockchain.

Slide 6

This slide illustrates the features of public blockchain technology. It also provides information regarding its characteristics such as full transparency, no regulations, true decentralization, immutable, anonymous nature, and open environment.

Instructor’s Notes:

The different characteristics of public blockchain are as follows:

Full Transparency:

• Public blockchain provides full access and allows individuals to see the ledger anytime
• Anyone can maintain the ledger and participate in consensus. This ensures that indulging in corruption is near-impossible

No Regulations:

True Decentralization:

• In a public blockchain, no centralized system is involved
• It is individuals' responsibility to maintain the nodes and update the ledgers in the blockchain network
• A public blockchain has no centralized system to track activity, which gives complete freedom to join the blockchain

Immutable:

Anonymous Nature:

• In a public blockchain, all the individual identities are anonymous, and it is not required to use real names
• Individual identities stay hidden, and it is not easy to track human behind the transactions

Open Environment:

• Public blockchain is open to all and any individual can participate in it

Slide 7

This slide illustrates the benefits of public blockchain technology, such as higher security, greater transparency, decentralized structure, and user empowerment.

Instructor’s Notes:

The multiple advantages of public blockchain are as follows:

• Higher Security: A blockchain system is not easy to hack. The larger the blockchain is, the more difficult it is for anyone person or entity to influence it
• Greater Transparency: All transaction records are shared with every member of the blockchain system in a distributed digital ledger resulting in more transparency
• User Empowerment: Any person with an internet connection can download a copy of the blockchain and can participate in maintaining the ledger

Slide 8

This slide showcases the multiple limitations of public blockchain technology, such as privacy limitations, lack of regulations and governance, public perception, cost of setup, and huge consumption of energy.

Instructor’s Notes:

The different challenges of public blockchain are as follows:

Privacy Limitations:

• Total security in the public blockchain is a tricky concept
• Data in the public blockchain is secure as long as it is not single-handedly controlled/influenced by some individual/entity
• The moment only one entity can unduly influence public blockchain data, the system loses its security. This is a logical possibility in newer or smaller blockchains

Lack of Regulations and Governance:

• The essential feature of Blockchain Technology is that it lacks regulatory oversight
• It allows peer-to-peer transactions, which leads to cutting off intermediaries
• It does not require governance from statutory bodies
• No one can be held accountable for maintaining the network standard, thus adding an element of skepticism to the entire system

Public Perception:

• Lack of supportive public perception is a significant hurdle to blockchain success
• Popular public opinion towards blockchain is that it is not a sustainable technology
• Features like lack of governance, easy access to public blockchain membership, and lack of regulation add to the unreliable public image of the blockchain technology

Cost of Set-Up:

• Establishing the entire blockchain Technology system is expensive due to:
  • High set-up cost
  • Limited skilled talent
  • Training costs

Huge Consumption of Energy:

• Blockchain's energy consumption for a cryptocurrency exchange is an important area of concern
• The Proof-of-Work mechanism consumes a lot of energy while solving complex mathematical problems

Slide 10

This slide illustrates the concept of private blockchain technology. It also provides information regarding the introduction, and examples of the private blockchain.

Slide 11

This slide illustrates the characteristics of private blockchain technology such as access, high transaction rate, security, and consensus algorithms.

Instructor’s Notes:

The different characteristics of private blockchain are as follows:

Access:

Higher Transaction Rate:

Security:

• A private blockchain is more susceptible to hacking, and data breaches
• It is easy for imperfect players to put the entire blockchain network at risk. Hence, it is less secure

Consensus Algorithms:

Slide 12

This slide illustrates the characteristics of private blockchain technology such as privacy, high efficiency, and better scalability.

Instructor’s Notes:

The different characteristics of private blockchain are as follows:

Privacy:

• In a private blockchain, the primary focus is on the privacy of all individuals
• A private blockchain is more centralized, so it is easy to maintain the confidentiality of the individuals

High Level of Efficiency:

• The efficiency of the private blockchain depends upon the number of nodes in the blockchain
• In a private blockchain, only limited pre-authorized nodes are added to the system, therefore the system works with better efficiency and speed

Energy Efficient:

Better Scalability:

• Since nodes and services can be added on-demand, it is far easier to achieve scalability in the private blockchain
• Due to limited nodes, the system does not slow down which results in reduced fees and faster transactions, leading to greater scalability

Slide 13

This slide illustrates the demerits of private blockchain technology, such as trust, high energy consumption and limited security.

Instructor’s Notes:

The different disadvantages of private blockchain are as follows:

Trust:

• Trust is a substantial issue for a private blockchain
• The credibility of a private blockchain network depends on the credibility of the authorized nodes
• The nodes have to be trustworthy as they verify and validate transactions
• The validity of records can’t be independently verified in a private blockchain

Security:

• Security is another concern with a private blockchain 
• Due to fewer nodes, it is easier for hackers to control the network
• In private blockchains, the risk of being hacked or having data manipulated is higher

Slide 15

This slide illustrates the concept of consortium blockchain technology. It also contains information regarding the introduction, and examples of consortium blockchain.

Slide 16

This slide illustrates the characteristics of consortium blockchain technology, such as faster speed, lower transaction costs, lower energy consumption, and no risk of 51% attack.

Instructor’s Notes:

The different characteristics of consortium blockchain are as follows:

• Faster Speed: The consortium blockchain provides a faster output compared to public blockchains. This is an improvement over public blockchains
• Lower Transaction Costs: Everything in the consortium blockchain is regulated, so the fee remains the same no matter how many users are on the network
• Lower Energy Consumption: In consortium blockchain, verification of all transactions and documents requires lower energy consumption than the public blockchain
• No-Risk of 51% Attack: The consortium blockchain offers greater degree of security and protection against the 51% attack

Slide 17

This slide showcases the benefits of consortium blockchain technology, such as control, security, and privacy.

Instructor’s Notes:

The different advantages of consortium blockchain are as follows:

Control:

• The consortium blockchain is controlled by multiple groups and is protected from monopoly
• Each member in the consortium blockchain settles and enables them to establish their own rules, change or cancel incorrect transactions, modify balances, and perform other actions

Security:

• Only selected members do validation and verification of nodes to avoid the 51% of attack
• Individuals violating rules are identified immediately and charged with penalties

Privacy:

• The information shared in the consortium blockchain is kept private and not disclosed to the public 
• It creates a significant level of trust and confidence for clients of the platform

Slide 18

This slide illustrates the demerits of consortium blockchain technology, such as unstable relationships, lack of economic model, flexibility issues.

Instructor’s Notes:

The different disadvantages of consortium blockchain are as follows:

Unstable Relationships:

Lack of Economic Model:

Flexibility Issues:

• The process of launching the consortium blockchain is susceptible
• All members must give their approval to the protocol for communication
• Since enterprises have little flexibility in making changes independently, thus that a broad network exists between enterprises is often significantly delayed

Slide 20

This slide illustrates the concept of hybrid blockchain technology. It also delivers information regarding the introduction, and example of hybrid blockchain.

Slide 21

This slide illustrates the characteristics of hybrid blockchain technology, such as secure, transparent, immutable, and decentralized.

Instructor’s Notes:

The different characteristics of hybrid blockchain are as follows:

Secure:

• Members in hybrid blockchain technology are selected to verify nodes
• In the hybrid model, any individual violating rules is identified immediately and charged with high fines

Transparent: 

• Trust is a more substantial issue for hybrid blockchain technology
• Transparency leads to trust generation in the system
• The credibility of a hybrid blockchain network depends on the credibility of the authorized nodes
• The nodes are trustworthy as they verify and validate transactions end-to-end

Immutable:

Decentralized:

Slide 22

This slide showcases the benefits of hybrid blockchain technology, such as works in closed ecosystem, flexibility in changing rules, protection from 51% attack, protecting privacy, and lower transaction cost.
