About Stablecoins: Nature: Stablecoins are a type of cryptocurrency that attempt to maintain stable prices as they are pegged to an underlying asset, such as a basket of currencies or precious metals like gold. Terminology: Although the term “stablecoin” is commonly used, there is no guarantee that the asset will maintain a stable value in relation to the value of the reference asset when traded on secondary markets or that the reserve of assets, if there is one, will be adequate to satisfy all redemptions. Difference with cryptocurrencies: Stablecoins are designed for everyday use, offering price stability unlike volatile cryptocurrencies like Bitcoin. They enable easy value transfer, support financial services, and maintain stability through collateral reserves or algorithmic supply control.  Popular stablecoins like Tether and USD Coin are backed by the US dollar. Types of Stablecoins: There are primarily three types of stablecoins: fiat-collateralized, crypto-collateralized, and non-collateralized (algorithmic). Fiat-collateralized stablecoins are pegged to a specific asset, such as a fiat currency.  The entity behind the stablecoin maintains a reserve of the asset or assets backing the stablecoin, supporting the value of the digital currency.  On the other hand, non-collateralized (algorithmic) stablecoins use software algorithms to automatically adjust the supply of the stablecoin based on demand, aiming to maintain a stable price. Status of stablecoins in India: India does not currently recognise stablecoins, treating all cryptocurrencies as Virtual Digital Assets (VDAs) under Section 2(47A) of the Income Tax Act, 1961. In 2023, VDAs were brought under the Prevention of Money Laundering Act, 2002, to curb misuse and enhance oversight. Central Bank Digital Currency (CBDC) or ‘Digital Rupee’ is India’s official alternative to stablecoins, which allows programmable payments (e.g., Direct Benefit Transfer (DBT) schemes), tracking usage by expiry, location, or purpose. Source: The Hindu Banni Festival Category: History & Culture Context: Two people were killed and more than a hundred were injured at the annual Banni festival at Devaragattu in Kurnool district of Andhra Pradesh. About Banni Festival: Nature: It is a tradition in Andhra Pradesh where villagers fight with sticks to claim a deity’s idol on Vijayadashami. The objective of this event is to snatch the idols from the God’s team, leading to a fierce battle known as the Banni Fight. Occasion: It is celebrated on the night of Dussehra celebration (Vijaya Dasami) every year. Location: It is held on the premises of Mala Malleswara Swamy Temple (situated at the border of Andhra Pradesh and Karnataka). Linkage with Vijayanagara Empire: This festival was celebrated by people under the Vijayanagara Empire. Significance: It is celebrated on the account of the victory of Lord Mala Malleswara Swamy and Goddess Parvati over demonish Mani and Mallasura, who troubled the people at Devaragattu region. Rituals: The ritual takes place at midnight when the procession of idols of the ruling deities Malamma (Parvati) and Malleshwara Swamy (Shiva) are brought down the hill temple at Neraneki. Devotees carry long sticks or lathis with them for hitting each other with these sticks on the head. The basic idea of this fight is to capture the procession idol. Source: The Hindu Presumptive Taxation Category: Economy Context: The government think tank Niti Aayog suggested the introduction of a presumptive taxation scheme for foreign companies to provide certainty and simplicity. About Presumptive Taxation: Nature: It is a simplified tax scheme where income is calculated based on a presumed rate of profit rather than actual income. Need: Despite India’s inherent appeal and remarkable FDI growth, structural impediments such as ambiguous PE (permanent establishment), regulations introduce tax uncertainty and dampen investments. Objectives: To provide relief to taxpayers from the tedious work of maintaining regular books of account under certain circumstances. To provide tax certainty and reduce compliance burdens. To align with India’s goal of becoming a global manufacturing hub under initiatives like Make in India. Importance: The optional presumptive taxation scheme would help resolve disputes concerning PE (permanent establishment), simplifying compliance and protecting revenue. By adopting a presumptive taxation scheme, India can transform its tax regime from a ‘minefield’ into a ‘well-lit path.’ Impact on businesses: A company opting for this scheme can declare income at a prescribed rate; in lieu of that, it is relieved from maintaining books of accounts for audit by tax authorities. Source: The Hindu NATO Category: International Relations Context: A quarter of a century after it joined NATO, Poland will finally join the alliance‘s fuel pipeline network, amid rising tension on its eastern frontier. About NATO: Nature: The North Atlantic Treaty Organization (NATO) is an intergovernmental military alliance. Formation: It was established on April 4, 1949, with the signing of the North Atlantic Treaty in Washington, D.C. by 12 founding member countries from Europe and North America. Objective: It was established with the primary goal of providing collective defence against potential aggression, particularly from the Soviet Union during the Cold War era. Over the years, NATO has evolved to address a range of security challenges beyond its original mandate. Uniqueness: NATO’s primary mission is collective defence, as outlined in Article 5 of the North Atlantic Treaty. This article stipulates that an attack on one member country will be considered an attack on all, and the members will respond collectively. Founding members: The original 12 founding members of NATO were Belgium, Canada, Denmark, France, Iceland, Italy, Luxembourg, the Netherlands, Norway, Portugal, the United Kingdom, and the United States. Expansion: NATO has expanded since its founding, with new member countries joining in multiple rounds. The alliance currently consists of 32 member countries. Political Leadership: The North Atlantic Council (NAC) serves as NATO’s principal political decision-making body, composed of ambassadors from all member countries. Funding: In 2006, NATO Defense Ministers agreed to a commitment that 2% of their countries’ GDP would be allocated towards defence spending. However, the majority of NATO members do not meet this

Archives (PRELIMS  Focus) Sir Creek Category: International Relations Context: Defence Minister Rajnath Singh warned Pakistan that “any aggression by Pakistan in the Sir Creek area will be met with a resounding response that will change both history and geography.” About Sir Creek: Disputed area: Sir Creek is a 96-km strip of water disputed between India and Pakistan in the Rann of Kutch marshlands. Nomenclature: Originally named Ban Ganga, Sir Creek is named after a British representative. Acts as a boundary: The Creek opens up in the Arabian Sea and roughly divides the Kutch region of Gujarat from the Sindh Province of Pakistan. Importance: Apart from strategic location, Sir Creek’s core importance is fishing resources. Sir Creek is considered to be among the largest fishing grounds in Asia. Possibility of oil and gas: The area has possible presence of great oil and gas concentration under the sea, which are currently unexploited thanks to the impending deadlock on the issue. Background of dispute: The dispute lies in the interpretation of the maritime boundary line between Kutch and Sindh. Pakistan claims the entire creek as per paragraphs 9 and 10 of the Bombay Government Resolution of 1914 signed between then the Government of Sindh and Rao Maharaj of Kutch, which set the boundary as the eastern flank of the creek popularly known as Green Line. But India claims that the boundary lies mid-channel as depicted in another map drawn in 1925, and implemented by the installation of mid-channel pillars back in 1924. In its support, it cites the Thalweg Doctrine in International Maritime Law, which states that river boundaries between two states may be divided by the mid-channel if the water-body is navigable. UNCLOS favours India’s stand: Acceding to India’s stance would mean shifting of the land/sea terminus point several kilometres to the detriment of Pakistan, leading in turn to a loss of several thousand square kilometres of its Exclusive Economic Zone under the United Nations Convention on Law of the Sea (UNCLOS). Sources: The Hindu Kathakali Category: History & Culture Context: Kerala Kalamandalam, Cheruthuruthy, witnessed history when 16-year-old Sabri, became the first Muslim girl to perform Kathakali at the prestigious institution since its founding in 1930. About Kathakali: Origin: Kathakali emerged in the 17th century in the kingdom of Travancore (present-day Kerala). The art form was initially performed in temple precincts and later gained popularity in the royal courts. Based on ancient texts: Kathakali is based on Natya Shastra, the ancient treatise on dance, written by Sage Bharata. However, It relies on Hasthalakshana Deepika, another classical text for its hand gestures. Precursors: Dance-drama art form called ‘Krishnanattam’ and Ramanattam based on Mahabharata and Ramayana are precursor of ‘Kathakali’. Composition: Kathakali combines elements of dance, music, mime, and drama. Features of dance: The four aspects of abhinaya – Angika, Aharya, Vachika, Satvikaand the Nritta, Nritya and Natya are combined perfectly in this dance form. Features of music: Kathakali music follows the traditional sopana sangeet of Kerala. It is said to be the ritual singing of the Ashtapadis on the flight of steps leading to the sanctum sanctorum. Use of Mudras: The movements are highly stylized and include intricate footwork, rhythmic swaying, and various hand gestures called mudras. Emphasis on facial expressions: The dancers use their facial expressions, known as rasas, to convey emotions and tell stories. Downfall in 20th century: Kathakali was in peril and on the verge of extinction in the beginning of 20th century. Revival: Renowned Poet Vallaththol Narayana Menon and Manakkulam Mukunda Raja took the initiative to set up Kerala Kalamandalam, a centre of excellence for classical art forms for the revival of kathakali. Major exponents: Kavungal Chathunni Panicker and Kalamandalam Gopi are its most eminent representatives.

Source: The Hindu Partition of Bengal Category: History & Culture Context: Recently, Undivided Bengal’ emerged as the popular theme of Durga Puja in West Bengal. About Partition of Bengal: Background: The Partition of Bengal in 1905 was initiated by Lord Curzon, the then Viceroy of India, citing administrative efficiency due to the vast size and population of Bengal. However, the underlying motive was to weaken the growing nationalist movement by dividing Hindus and Muslims. Bengal was split into two provinces: Eastern Bengal and Assam (Muslim-majority) and Western Bengal (Hindu-majority). The move was widely opposed by Indian nationalists, who saw it as a strategy of “divide and rule.” The partition sparked widespread protests and gave rise to the Swadeshi Movement, eventually leading to its annulment in 1911.

Modern Internet dependence: Cloud infrastructure, dominated by few companies like Microsoft, is crucial for states but can also aid repression (e.g., in Palestine). Export control regimes: Agreements like the Wassenaar Arrangement aim to regulate export of sensitive goods and dual-use technologies to prevent misuse. Limitations of current framework: Focused mainly on physical exports (devices, chips, hardware). Struggles to regulate cloud services, APIs, and remotely accessed technologies. Leaves loopholes for “intrusion software” and surveillance misuse. India’s role: Joined in 2017, regularly updates control lists but faces challenges in ensuring compliance. Reform needs: Expand definitions to cover remote access, cloud exports, and digital surveillance. Introduce binding global treaties with clearer licensing and oversight. Create domain-specific controls for AI and high-risk digital tools. Global implications: Divergent national licensing can create loopholes. Stronger coordination needed to prevent misuse across borders. Possible measures: Tighter export scrutiny for cloud services. Binding international commitments. Technical expert committees to guide regulation. Conclusion: Existing arrangements are outdated; comprehensive reforms are essential to regulate 21st-century technologies without stifling innovation. Learning Corner: Wassenaar Arrangement (WA) Nature: A multilateral export control regime for conventional arms and dual-use goods and technologies. Established: 1996, in Wassenaar, Netherlands. Objective: To promote transparency and responsibility in transfers of arms and sensitive technologies. To prevent destabilising accumulations of weapons and technologies that could aid in proliferation or repression. Membership: 42 participating states (as of 2025), including India, the U.S., most EU states, Japan, etc. India’s membership: Joined in December 2017. Mechanism: States exchange information on transfers/denials of items listed in WA control lists. It is non-binding; decisions on licensing remain at the discretion of each state.

rchives (PRELIMS  Focus) Soilification Category: AGRICULTURE Context:  Researchers in Rajasthan successfully grew wheat in desert land using an indigenous bioformulation-based soilification technology, showing potential to stop desertification and boost agriculture in arid regions. Experiment site: Conducted by Central University of Rajasthan (CUoR) at Banseli village, Ajmer district. Technology: Used desert ‘soilification’ with indigenous bioformulation to convert desert sand into soil-like structure. Water efficiency: Wheat required only 3 irrigations (vs. 5–6 normally) due to high water retention. Key features: Bioformulation enhanced water retention, improved soil structure, stimulated microbial activity, and increased crop stress resistance. Pilot results: 13 kg wheat seeds yielded 26 kg harvest per 100 sq. metres in April 2025. Higher yield: Experimental field with bajra, guar gum, and chickpea showed 54% higher yield in bioformulation-amended sand. Support: Facilitated by Krishi Vigyan Kendra (KVK) and Rajasthan Horticulture Department. Impact: Reduced water input, higher productivity, and potential to curb desertification in Thar desert region. Future plan: Expand technology to crops like millet and green gram in Rajasthan’s dry regions. Learning Corner: Soilification Meaning: Soilification is a process of transforming loose, infertile sand (desert soil) into soil-like material that can support plant growth. How it works: Uses polymers, bioformulations, or natural binders to cross-link sand particles. Improves soil aggregation and water retention capacity. Enriches the substrate with microbial activity to provide nutrients and resilience to crops. Key Objectives: Convert arid, barren desert land into productive agricultural fields. Reduce irrigation demand by retaining more water in sandy soils. Combat desertification and land degradation. Applications: Tested in Rajasthan’s Thar Desert for wheat, bajra, guar gum, and chickpea cultivation. Used in dry and semi-arid regions globally (China, Middle East, Africa) to reclaim deserts. Significance: Provides a sustainable land restoration method. Helps ensure food security in desert-prone countries. Supports climate change adaptation by reclaiming degraded lands.

Disease: H3N2 is an Influenza A subtype virus causing respiratory illness. Current trend: Hospitals report rise in cases; August saw ~80, September ~100 cases. Symptoms: Fever, body ache, cough, sore throat, congestion; symptoms more intense this year. Spread: Transmitted through coughing, close contact, and contaminated surfaces. Vulnerable groups: Elderly, children, pregnant women, people with diabetes, asthma, heart/kidney disease, or low immunity. Illness duration: Typically lasts 5–7 days; cough and weakness may persist for weeks. Complications: Risk of secondary bacterial infection in those with comorbidities. Precaution: Avoid close contact, wear masks, maintain hygiene, get vaccinated. Challenge: Difficult to confirm if H3N2 cases are rising due to inadequate surveillance. Doctors’ advice: Urgent need for vaccination, especially for high-risk groups. Learning Corner: Avian Influenza (Avian Flu)  A zoonotic viral infection caused by Influenza A viruses that primarily affect birds but can infect humans and other animals. Classified into Low Pathogenic Avian Influenza (LPAI) and Highly Pathogenic Avian Influenza (HPAI) depending on severity in poultry. Major Types / Strains H5N1 First detected in humans in 1997 (Hong Kong). Highly pathogenic; causes severe respiratory illness with high fatality rate. Endemic in parts of Asia and Africa. Limited human-to-human transmission. H7N9 First reported in humans in China (2013). Usually low pathogenic in birds but can cause severe illness in humans. High mortality among reported human cases. H5N6 Reported in poultry outbreaks in Asia. Sporadic human infections (mostly in China). Causes severe respiratory disease in humans. H9N2 Low pathogenic in birds. Human infections are usually mild. Important because it can mix with other influenza viruses, acting as a “gene donor” for new strains. H10N3 / H10N8 Rare human cases reported in China. H10N8 caused fatal cases in 2013. Still considered sporadic but monitored for pandemic potential. H3N2 (variant of concern for humans, not birds alone) Causes seasonal influenza in humans, but also linked with zoonotic spillover. Not classified as a classic “avian flu,” but shares cross-species transmission risks.

rchives (PRELIMS  Focus) Agni-Prime (Agni-P) ballistic missile Category: SCIENCE AND TECHNOLOGY Context:  India successfully test-fired the Agni-Prime (Agni-P) ballistic missile from a rail-based mobile launcher, marking a strategic milestone.  The Defence Research and Development Organisation (DRDO) tested the Agni-P missile from a rail-based launcher, placing India among a select group of nations with such “canisterised launch systems.” Rail-based platforms enhance second-strike capability by providing mobility, concealment, and survivability against enemy surveillance compared to vulnerable fixed silos. They are cheaper and easier to scale than submarine-based systems, leveraging India’s extensive railway network. Agni-P, a two-stage solid-fuel missile with a range of 1,000–2,000 km, succeeds Agni-I with improved guidance, propulsion, and warhead technology. Learning Corner: Agni-P (Agni-Prime) missile: Type: New-generation, medium-range ballistic missile (MRBM). Developer: Defence Research and Development Organisation (DRDO). Range: 1,000 – 2,000 km. Propulsion: Two-stage, solid-fuel propulsion system. Launch Platforms: Canisterised system—deployable from road and rail-based mobile launchers, enhancing mobility and survivability. Features: Advanced navigation and guidance system. Improved accuracy compared to earlier Agni variants. Lighter composite materials, making it more efficient. Strategic Importance: Enhances India’s second-strike capability. Provides flexibility to evade enemy surveillance by using mobile launchers. Cheaper alternative compared to submarine-launched ballistic missiles (SLBMs). Successor: Designed as a successor to Agni-I with modernised systems. Integrated Guided Missile Development Programme (IGMDP) Launch: 1983, by DRDO, under the leadership of Dr. A.P.J. Abdul Kalam. Aim: To make India self-reliant in missile technology and develop a series of indigenous guided missiles. Significance: Reduced dependence on foreign technology (especially due to MTCR restrictions), created a strong base for future missile projects, and strengthened India’s defence preparedness. Closure: Officially declared completed in 2008, after most projects achieved their objectives. Missiles Developed under IGMDP Prithvi – Surface-to-surface short-range ballistic missile (SRBM); first missile developed under IGMDP. Agni – Initially a technology demonstrator for re-entry vehicles; later evolved into a family of medium to intercontinental range ballistic missiles (MRBM → ICBM). Akash – Medium-range, surface-to-air missile (SAM); inducted into the Indian Air Force and Army. Trishul – Short-range, quick-reaction surface-to-air missile; served mainly as a technology demonstrator. Nag – Third-generation, fire-and-forget anti-tank guided missile (ATGM); inducted after extensive trials. Source: THE INDIAN EXPRESS Article 304(a) Category: POLITY Context : The Supreme Court struck down Rajasthan’s 2007 VAT exemption on locally made goods, ruling that taxation cannot discriminate against goods from other states. The Supreme Court quashed a Rajasthan notification that exempted VAT on locally manufactured asbestos sheets and bricks, which disadvantaged goods imported from other states. The bench held this violated Article 304(a) of the Constitution, which prohibits states from imposing discriminatory taxes on out-of-state goods. The Court emphasized that taxation cannot be used as a tool to restrict trade or create unfair advantages for local products, reaffirming the principle of free and non-discriminatory trade across India. Learning Corner: Article 304(a) of the Constitution: Provision: Article 304(a) of the Indian Constitution allows State Legislatures to impose taxes on goods imported from other States or Union Territories, but such taxation cannot discriminate between imported goods and similar goods produced within the State. Objective: To ensure free trade, commerce, and intercourse throughout India (as guaranteed under Article 301) while permitting States to levy taxes for revenue purposes. Key Principle: Taxes must be non-discriminatory—i.e., goods from other States should not be treated unfavorably compared to locally produced goods. Judicial Interpretation: The Supreme Court has consistently held that taxation cannot be used as a weapon to create economic barriers or protectionism within a State. Discriminatory tax laws violate the spirit of national economic unity.
