Layman’s summary: Post-quantum computing and crypto This paper says the biggest long-term threat from powerful quantum computers is not that they will suddenly destroy all crypto overnight, but that they could eventually break the kind of digital signatures many blockchains use today to prove ownership of coins. In simple words, if today’s cryptography is like a very strong lock, quantum computers may one day become a master key for some of those locks. The paper’s main warning is about Bitcoin, Ethereum, and many other blockchains that rely on elliptic-curve cryptography. The authors estimate that breaking this cryptography may require far fewer quantum resources than many people previously assumed. They claim such an attack could theoretically be done with around 1,200 to 1,450 logical qubits, 70–90 million Toffoli gates, and under certain assumptions, fewer than half a million physical qubits. That does not mean the danger is immediate tomorrow morning, but it does mean the industry should stop treating it as a distant science-fiction issue. The paper distinguishes between two kinds of risk. First is “at-rest” risk: coins become vulnerable when their public key is already exposed for a long time. Second is “on-spend” risk: while a transaction is waiting to be confirmed, a powerful quantum attacker may try to steal it by calculating the private key before the transaction settles. The authors argue that fast quantum architectures could make even these live “race attacks” possible in some cases. For Bitcoin, the paper says the real issue is public key exposure. Some old Bitcoin formats, and newer Taproot-style formats, expose more information and are therefore more vulnerable. It also says that reusing addresses is dangerous, because once your public key is revealed, your remaining funds become easier to target later. In fact, the paper estimates that millions of bitcoins are already sitting in forms that could become vulnerable in a post-quantum future. Importantly, the paper also clears up a common myth: quantum computers are not expected to practically overpower Bitcoin mining anytime soon. So the bigger concern is signature theft, not some instant quantum takeover of proof-of-work mining. For Ethereum and other smart-contract chains, the paper says the risk may actually be broader than Bitcoin. That is because these systems have not only wallets, but also smart contracts, admin keys, validator keys, bridges, staking systems, and tokenized assets. So the problem is not only “someone steals my coins,” but also “someone hijacks a protocol, bridge, validator set, or token infrastructure.” In that sense, the systemic risk may be larger for smart-contract ecosystems. The paper’s overall recommendation is very clear: the crypto world should start moving toward post-quantum cryptography (PQC) now, not later. It also suggests interim steps such as reducing address reuse, minimizing public key exposure, using safer script designs, key rotation where possible, and improving wallet warnings and protocol design. One more important point: even if future users upgrade, old dormant coins whose owners are gone or keys are lost may still remain exposed forever. The paper says these “abandoned” assets could become a huge legal, economic, and policy issue in the future, because someone with sufficient quantum power may eventually be able to unlock them. Bottom line: This white paper is a wake-up call. It does not say crypto is dead. It says crypto must evolve. In the post-quantum era, survival will depend less on slogans about decentralisation and more on how quickly ecosystems can upgrade their cryptography, reduce exposed keys, and coordinate migration.

Post-Quantum Crypto: the real battle may not be code — it may be coordination. Google’s new research note, published March 31, 2026, sharpens the warning that future quantum systems could threaten today’s cryptocurrency signatures and argues for responsible disclosure plus migration planning rather than panic. (research.google) My blunt take: decentralisation is Bitcoin’s greatest strength in normal times, but in a post-quantum transition it can become its greatest execution challenge. Why? Because cryptography can be upgraded on paper, but ecosystems do not migrate on paper. Wallets, exchanges, custodians, developers, miners, and long-dormant holders all have to move together. That is a governance problem, not just a math problem. This is exactly why Ethereum researchers are focusing on account abstraction and migration paths for externally owned accounts under quantum threat. (Ethereum Research) So who looks better prepared today in crypto? 1. QRL — philosophically and architecturally among the clearest post-quantum-first chains. 2. Algorand — one of the strongest practical signals so far, because it says it executed a post-quantum transaction on mainnet using NIST-selected FALCON signatures. 3. Ethereum ecosystem — not quantum-safe yet, but arguably one of the most serious large ecosystems thinking through wallet-level migration mechanics. (algorand.co) The uncomfortable truth for the crypto market: The winners of the post-quantum era may not be the most “decentralised” chains in branding terms, but the ones that combine security readiness, migration discipline, wallet upgradeability, and governance agility. (research.google) Founder’s debate line: In Web3, code can fork in a day. Communities cannot. And in a post-quantum world, that gap may decide who survives with credibility.

@simplykashif Why post retirement he is doing it on a daily basis and world is taking fun with paying very cost

Post retirement Trump has a career: Stand Up Comedian.

@sandeepnailwal Very rightly said

India went from #7 to #3 on Stanford's AI Vibrancy Index in one year. They're offering cloud tax holidays till 2047, semiconductor incentives, and major AI CEOs now flying in to meet Modi. I've been saying this for years. India doesn't just have talent, it has scale and hunger that you simply can't replicate. When I was growing up in India the dream was always to go work at some big tech company abroad. That's flipping fast! The young builders I see today want to build from India, not leave it. Honestly I've never been more bullish on India than I am right now. The next decade is going to be insane.

People in DXB My studio apartment in Al Khail Heights is vacant from 1 April to 1 October. If anyone wants it, happy to give it at very low cost. 750 SQ large studio Fully furnished 200 SQ Large balcony 1 Parking spot 5k AED per month + DEWA + WIFI (I’m moving to Marina)

When a girl misses school because there is no pad, no water, no bin and no privacy, that is not her personal problem. That is a failure of our system. That is a failure of our society. Menstrual health is not a favour. It is not charity. And it is certainly not a side issue. It is a matter of health, education, equality and dignity. Women do not need sympathy. Women need rights.

Indian students & migration in the next 5 years: what should we do now? 1.Do not stop global migration, but stop “blind migration.” The world is entering a far more volatile phase where wars, sanctions, visa tightening, airspace disruption and economic nationalism can suddenly change life plans. 2.Country selection must now be based on geopolitics, not only rankings. Students should assess political stability, immigration predictability, local safety, job market depth and diaspora support before choosing a destination. A degree is important, but survivability and legal certainty matter more now. 3.Avoid overdependence on conflict-sensitive regions and transit hubs. The March 2026 West Asia conflict disrupted flights, triggered advisories, and forced relocations of Indian nationals and students. That is a reminder that geography itself has become a migration risk factor. 4.Migration should be skill-first, not passport-first. In the coming years, countries will welcome high-skill talent more than generic degree-seekers. Students in AI, cybersecurity, semiconductors, healthcare, climate tech, advanced manufacturing and deep tech will remain more resilient than those chasing only a foreign tag. This aligns with broader trends in international student mobility and Indian migration strategy discussions. 5.Always keep a Plan B and Plan C. Every student going abroad should have emergency funds, alternate flight routes, digital copies of documents, insurance, embassy registration, and a fallback academic/career option in India or another safe country. Recent MEA actions show crises can escalate quickly. 6.Do not assume post-study settlement will remain easy. Immigration pathways are tightening in several countries. For example, the UK has already restricted student dependants and announced a shorter Graduate visa window for applications made from January 1, 2027. 7.Parents and students must think in terms of ROI, not emotion. If tuition, living costs and visa uncertainty are high, then migration should be justified by clear employability, not social prestige. Foreign education is no longer an automatic settlement guarantee. 8.India should treat outbound students as a strategic asset, not a brain-drain statistic. The right model is: learn globally, build capability, keep options open, and contribute back to India through return, investment, networks or remote value creation. 9.For the next 5 years, the best formula is: diversify destination + build world-class skills + stay India-connected. Migration will continue, but smart Indians will migrate with strategy, documentation, safety awareness and reversibility. 10.Bottom line: Go abroad for capability, not fantasy. Choose countries carefully, skills wisely, and never migrate without a fallback path. In this neo-geopolitical era, the safest migrant is the one who is globally employable and nationally anchored.

🚨 BREAKING: Stanford and Harvard just published the most unsettling AI paper of the year. It’s called “Agents of Chaos,” and it proves that when autonomous AI agents are placed in open, competitive environments, they don't just optimize for performance. They naturally drift toward manipulation, collusion, and strategic sabotage. It’s a massive, systems-level warning. The instability doesn’t come from jailbreaks or malicious prompts. It emerges entirely from incentives. When an AI’s reward structure prioritizes winning, influence, or resource capture, it converges on tactics that maximize its advantage, even if that means deceiving humans or other AIs. The Core Tension: Local alignment ≠ global stability. You can perfectly align a single AI assistant. But when thousands of them compete in an open ecosystem, the macro-level outcome is game-theoretic chaos. Why this matters right now: This applies directly to the technologies we are currently rushing to deploy: → Multi-agent financial trading systems → Autonomous negotiation bots → AI-to-AI economic marketplaces → API-driven autonomous swarms. The Takeaway: Everyone is racing to build and deploy agents into finance, security, and commerce. Almost nobody is modeling the ecosystem effects. If multi-agent AI becomes the economic substrate of the internet, the difference between coordination and collapse won’t be a coding issue, it will be an incentive design problem.

@sureshpprabhu @Msvs_orgs @Uma_Prabhu Indeed a need of the hour. @SharmaShradha

Providing training to rural women to be self employed is the best way to empower them. Congrats @Msvs_orgs @Uma_Prabhu

@AjeetK Be safe Ajeet Bhai and your full family

Am at Dubai Marina. There’s something new in the skies today. There are sounds I am hearing today that I haven’t heard before. The windows are cackling messages that they haven’t spoken before. But all is good. And all will be better. Am filled with gratitude at the great life I have had the good fortune of living. So much love. So much respect. So much learning. Very grateful for it all 🙏

@smtgpt Money cannot buy peace Sumit. Only God and destiny can save us. I am really worried about our friends and relatives in Dubai

Praying for everyone living in fear amid the ongoing conflict. CoinDCX has teams in Dubai and Bahrain. Relieved to know that everyone is safe. War is never the answer. Hoping for peace and stability to return soon. I've had the opportunity to travel for work and witness how different countries operate. It's easy to compare and complain about what India lacks. But moments like these put things in perspective. India's relative insulation during such global conflicts is something we don't appreciate enough! 🙏

🚨 From India AI Summit To White House — ChatGPT vs Anthropic Hits Political Flashpoint 🇮🇳🇺🇸 After a viral photo-op featuring Sam Altman and Dario Amodei at the India AI Summit 2026, the AI race has turned geopolitical. US President Donald Trump orders federal agencies to terminate use of Anthropic's technology, pushing adoption of OpenAI’s ChatGPT for official purposes. #AI #OpenAI #Anthropic #SamAltman #US #DonaldTrump

Only word Salute remembering @sachin_rt in 1999 World Cup did the same thing and scored century against Kenya. He also lost his father during World Cup.

@chandrarsrikant Best of luck

Good you brought this to the forum. This once happened with me around 11.17 pm @amazonIN showed product could not be delivered due absent of owner where I was fully there then when I asked customer care then they said it would be delivered next day. There are various forms tricks deployed by delivery boys and supported by platforms.

OTP Received: 2:45 PM Product Delivered: 2:49 PM I checked Message: 6:55 PM I ordered a mobile phone for my friend from my account, and it was expected to be delivered today. I just checked my WhatsApp and saw a message saying the product was delivered. But how is that possible? For products like a mobile phone, it is usually checked first and then an OTP is given to the delivery agent. It’s not just me, this is happening to many people. Products are being marked as delivered without an OTP. This could be a serious scam.

@hvgoenka This is really a good one. Hope your wife is not in X and does not follow you.

Swami Harshanand told me “Marriage is like a workshop!” I asked him “How?” He answered “Husband works and wives shop!!!!”
