3.8 PROOF OF STAKE (POS) 
Proof of Stake (PoS) is a consensus mechanism used in blockchain networks to validate transactions and 
secure the network. In PoS, network participants who stake their cryptocurrency are randomly selected to 
validate blocks of transactions. Those who successfully validate blocks are rewarded with additional 
cryptocurrency. 
Features of PoS: 
• Energy Efficient: PoS is a more energy-efficient and environmentally friendly alternative to Proof of 
Work (PoW), the consensus mechanism used by Bitcoin and Ethereum. 
• Scalable: PoS is also more scalable than PoW. Because PoS does not require miners to solve complex 
mathematical problems, it can process more transactions per second. 
• Handle High Volume Data: This makes PoS well-suited for blockchain networks that need to handle a high 
volume of transactions, such as those used for decentralized finance (DeFi) and non-fungible tokens (NFTs). 
 
Working of Proof of Stake: 
• Validate Blocks: In PoS, network participants who want to validate blocks must stake a certain amount of 
cryptocurrency. The amount of cryptocurrency that must be staked is determined by the network's protocol. 
• Validator: When a new block is created, a random number generator is used to select a validator from the 
pool of stakers. The validator who is selected is responsible for validating the block and adding it to the 
blockchain. 
• Reward : If the validator successfully validates the block, they are rewarded with additional cryptocurrency. 
However, if the validator fails to validate the block, they may lose some or all of their stake. 
• Incentives: This system incentivizes validators to behave honestly and to validate blocks correctly. If a 
validator tries to cheat or attack the network, they risk losing their stake. 
 
Advantages of Proof of Stake: 
• Energy efficiency: PoS is much more energy efficient than PoW. This is because PoS does not require miners 
to use powerful computers to solve complex mathematical problems. 
• Scalability: PoS is more scalable than PoW. This is because PoS does not require miners to solve complex 
mathematical problems, it can process more transactions per second. 
• Security: PoS is just as secure as PoW. This is because validators are incentivized to behave honestly and to 
validate blocks correctly. 
 
Disadvantages of Proof of Stake: 
• Centralization: PoS can lead to centralization of the network. This is because validators who have more 
stake have a greater chance of being selected to validate blocks. 
• Security: PoS is not as secure as PoW against 51% attacks. This is because a 51% attack in PoS only requires 
control of 51% of the stake, while a 51% attack in PoW requires control of 51% of the mining hashrate. 
 
Conclusion: 
PoS is a promising consensus mechanism that has the potential to replace PoW in the future. PoS is more energy 
efficient, scalable, and secure than PoW. However, PoS also has some disadvantages, such as the potential for 
centralization and security risks.

force can overcome the repulsive force of the protons in their nuclei. When this happens, the nuclei fuse 
together to form a new nucleus. 
• The mass of the new nucleus is less than the sum of the masses of the original nuclei. This difference in mass 
is converted into energy, according to Einstein's famous equation E = mc^2. 
 
Applications: 
• Nuclear fusion is the process that powers the sun and other stars. It is also the process that is being pursued 
as a potential source of energy on Earth. 
• Fusion reactors have the potential to produce large amounts of energy without producing greenhouse 
gasses. However, fusion reactors are still in the early stages of development.

the materials and components. Developing materials that can withstand high temperatures, intense 
radiation, and neutron bombardment while maintaining structural integrity is a significant challenge. 
• Cost and Scalability: Fusion energy currently requires significantinvestment and is not yet economically 
competitive with other forms of energy generation. Developing cost-effective fusion technologies and scaling 
them up for commercial power production is a major challenge. 
• Waste Management: While fusion reactions produce relatively little long-lived radioactive waste compared 
to fission reactions, managing and safely disposing of any waste generated by fusion reactors remains an 
important consideration. 
Conclusion: 
Fusion energy is a promising new source of energy with the potential to provide a clean, safe, and abundant 
source of energy for the world. However, there are still a number of challenges that need to be overcome before 
fusion reactors can be commercially viable. With continued research and development, it is possible that fusion 
energy will be a reality in the not-too-distant future. 
Additional Points:

million°C. While the duration and temperature alone aren’t recorded, the simultaneous achievement of 
heat and stability brings us a step closer to a viable fusion reactor. 
• China: China's "artificial sun" broke all records by generating extremely hot plasma for seven minutes 
on the night of April 12. The project, based on nuclear fusion, provides China with an unlimited energy 
source without producing residual waste. 
India and ITER: 
• Recognizing the significance of ITER in the development of fusion energy, India expressed its desire to 
join the project as an equal partner, alongside the existing six partners. 
• Following a series of steps and negotiations, India successfully became a partner in the ITER project. 
• As part of its contribution, India will provide equipment valued at approximately 500 million US dollars

5.4 TRANS FATS 
Trans fats are unsaturated fats that have been artificially altered to make them solid at room temperature. 
They are created by adding hydrogen to liquid vegetable oils, a process known as hydrogenation. Trans fats 
are often used in processed foods to improve texture, shelf life, and flavor. 
About Trans Fats: 
• Trans fats are considered to be unhealthy, Trans fat is solid at room temperature and is often used in 
processed foods to improve texture and shelf life. They raise LDL (bad) cholesterol and lower HDL (good) 
cholesterol. This can increase the risk of heart disease, stroke, and type 2 diabetes. 
• The World Health Organization (WHO) recommends that people consume no more than 2 grams of trans 
fat per day. 
• WHO and Indian initiatives combat antimicrobial resistance (AMR) through awareness programs, 
surveillance systems, promoting rational use of antibiotics, and strengthening infection prevention and 
control measures.112 
 PRAHAAR ReDEFINED 3.0: Science & Tech 
Types of trans fats: 
• Naturally occurring trans fats are found in small amounts in some animal products, such as beef, lamb, 
and dairy products. 
• Industrially produced trans fats are the type of trans fat that is most harmful to health. They are found in 
a wide variety of processed foods, including fried foods, baked goods, snack foods, and frozen dinners. 
Government Initiatives: 
• The Food Safety and Standards Authority of India (FSSAI) has issued directives to reduce the trans fat 
content in food products. The directives come into effect from January 1, 2022. 
➢ The maximum limit of industrially produced trans fat in food products is 2% by mass of the total fat 
content. 
➢ This means that a food product that contains 100 grams of fat can have no more than 2 grams of 
industrially produced trans fat. 
➢ The directives also state that food products that contain more than 0.5 grams of industrially produced 
trans fat per 100 grams of fat must be labeled with the following statement: "Contains industrially 
produced trans fat." 
• The World Health Organization (WHO) recommends that people consume no more than 2 grams of trans fat 
per day. 
 
Significant step towards reducing the trans-fat by FSSAI: 
• The directives apply to all food products that are sold in India, including packaged foods, restaurant food, 
and food prepared in homes. 
• Food businesses that violate the directives could face penalties, including fines and imprisonment. 
• The FSSAI has created a helpline for businesses that have questions about the directives. The helpline 
number is 1800-11-4056. 
Additional Information: 
"WHO calls on governments to use the REPLACE action package to eliminate industrially-produced trans-fatty 
acids from the food supply,"said WHO Director-General, Dr Tedros Adhanom Ghebreyesus. "Implementing the 
six strategic actions in the REPLACE package will help achieve the elimination of trans fat, and represent a 
major victory in the global fight against cardiovascular disease." 
 
REPLACE provides six strategic actions to ensure the prompt, complete, and sustained elimination of 
industrially-produced trans fats from the food supply. 
• REview dietary sources of industrially-produced trans fats and the landscape for required policy change. 
• Promote the replacement of industrially-produced trans fats with healthier fats and oils. 
• Legislate or enact regulatory actions to eliminate industrially-produced trans fats. 
• Assess and monitor trans fats content in the food supply and changes in trans fat consumption in the 
population. 
• Create awareness of the negative health impact of trans fats among policy makers, producers, suppliers, 
and the public.

6.9 INTELLECTUAL PROPERTY RIGHTS (IPR) 
Intellectual property rights (IPR) are legal protections granted to individuals or entities for their 
intellectual creations, such as inventions, artistic works, and symbols used in business. 
• These rights bestow upon creators exclusive control and benefits over the use of their creations for a specific 
duration. 
• The concept of IPR is rooted in Article 27 of the Universal Declaration of Human Rights, which upholds 
the right to safeguard moral and material interests derived from scientific, literary, or artistic authorship. 
• The significance of intellectual property was initially acknowledged in two key international agreements: 
the Paris Convention for the Protection of Industrial Property (1883) and the Berne Convention for 
the Protection of Literary and Artistic Works (1886). 
• Both treaties are overseen by the World Intellectual Property Organization (WIPO), an international 
body that promotes the protection and enforcement of intellectual property rights on a global scale. 
• These conventions and the subsequent development of various national and regional laws aim to 
incentivize innovation, creativity, and economic growth by ensuring that creators can reap the rewards 
of their intellectual endeavors while fostering a balance between the interests of rights holders and the 
wider public. 
 
Intellectual property rights encompass two primary domains: 
• Copyright and Related Rights: This category safeguards the rights of authors, creators, and artists in their 
literary and artistic works. These works include books, writings, musical compositions, paintings, 
sculptures, computer programs, and films. Copyright protection extends for a minimum duration of 50 years 
after the author's demise.

Protection of Distinctive Signs: 
• This aspect focuses on safeguarding trademarks and geographical indications. 
• Trademarks serve to differentiate the goods or services of one company from those of its competitors. 
• Geographical indications (GIs) are employed to identify goods that possess specific qualities primarily 
associated with their geographical origin. 
• Protecting such distinctive signs aims to foster fair competition, empower consumers to make informed 
choices, and ensure their well-being. 
• The duration of protection for these signs can be indefinite, provided they retain their distinctiveness. 
 
Industrial Designs and Trade Secrets: 
• This category revolves around the protection of various forms of industrial property with the core 
objective of encouraging innovation, design, and technological advancements. 
• It includes inventions (shielded by patents), industrial designs, and trade secrets. 
• Patents grant exclusive rights to inventors for a specified period, fostering innovation and allowing 
inventors to capitalize on their creations. 
• Industrial designs encompass the aesthetic and ornamental aspects of objects, while trade secrets 
safeguard valuable confidential information that provides a competitive edge.
