#Bitcoin is #halal because it’s built on truth: no pre-mine, no insiders, no yield from passive holding. You earn it through real work — energy, computation, time. It’s scarce, transparent, and #permissionless. No rulers, no rent-seekers. #Altcoins? Most are centralised, pre-mined, VC-funded yield schemes. They print tokens, hand them to insiders, and call it “innovation.” You stake, they inflate. You hold, they dilute. You earn yield from nothing — that’s potentially #riba (and in some cases, it definitely is). Bitcoin is a monetary system grounded in #thermodynamics and justice. Altcoins are Ponzi tech wrapped in buzzwords. If you care about halal, sovereignty, and truth — there’s only one chain worth your time. #BitcoinIsHalal #RibaFree #ShitcoinAlert

🔥 #Thermodynamics & #Bitcoin Mining: The Core Connection Thermodynamics is deeply linked to Bitcoin mining — not just metaphorically, but physically and mathematically. Here's how: ⚙️ 1. Proof of Work = Physical Work - Bitcoin mining involves solving SHA-256 puzzles by brute-force. - This requires electrical energy to perform billions of hash computations per second. - That energy is converted into heat — a direct manifestation of the First Law of Thermodynamics (conservation of energy). > Mining is not symbolic “work” — it’s literal energy expenditure, measurable in joules and watts. 🌡️ 2. Entropy & Information Theory - Mining reduces entropy by organising information (valid blocks). - But this comes at a thermodynamic cost: irreversible computation generates heat. - According to Landauer’s Principle, erasing or processing information has a minimum energy cost — Bitcoin mining operates far above this bound. 🔁 3. Heat as a Byproduct - Mining rigs dissipate massive heat, often through air or liquid cooling. - Some setups recover this heat for secondary use — e.g., heating water or buildings. - This aligns with the Second Law of Thermodynamics: energy transformations are never 100% efficient. 🛡️ 4. Security Through Energy - Bitcoin’s security is thermodynamic: altering the blockchain requires re-doing all the work — i.e., expending equivalent energy. - This makes attacks economically and physically infeasible, anchoring Bitcoin’s immutability in the laws of physics. 🧠 Why This Matters - Bitcoin is the first monetary system grounded in thermodynamic reality. - Its scarcity and security are not based on trust or decree, but on energy expenditure. - This gives it a unique ethical and physical integrity — unlike fiat or PoS systems, which rely on abstract consensus or inflationary models. #ProofOfWork #PoW

🔐 What Is the Nonce in #Bitcoin Mining? The nonce (short for number used once) is a 32-bit field in the block header that miners adjust during the mining process. Its sole purpose is to help miners find a valid hash that meets the network’s difficulty target. ⚙️ Function of the Nonce 🎯 1. Solving the Proof-of-Work Puzzle - Bitcoin uses SHA-256 to hash block headers. - The goal is to find a hash that is numerically lower than the current difficulty target. - Since SHA-256 is deterministic but unpredictable, miners must brute-force different inputs to find a valid hash. 🔁 2. Nonce as a Variable Input - The nonce is the only field in the block header that miners can freely and rapidly change. - By incrementing the nonce, miners generate new hash outputs without altering the block’s contents. - If all nonce values are exhausted (i.e., 0 to 4,294,967,295), miners must change other fields (like the timestamp or transaction set) to continue. 🧩 3. Ensuring Uniqueness - Each block must have a unique hash. - The nonce contributes to this uniqueness, ensuring that even identical transaction sets can yield different block hashes. 🧠 Why This Matters - The nonce is not symbolic — it’s the core mechanism that enables the probabilistic search for a valid block. - It’s what makes Bitcoin’s PoW verifiable and secure: anyone can check the hash and confirm it meets the difficulty target. - It’s also what makes mining non-trivial — you must expend real computational effort to discover the correct nonce. 🧪 Analogy (but not gold mining!) Think of it like trying to crack a safe: - You know the combination must produce a certain result (a hash below the target). - You keep trying different combinations (nonces) until one works. - The nonce is your dial — the thing you spin to try new outcomes.

What happens when we switch to a #Bitcoin Standard? Let’s break it down — for families, businesses, and governments. TL;DR: The Bitcoin Standard means… – Families save without fear – Businesses grow without banks – Governments govern without inflation – Humanity transacts without permission It’s not utopia. It’s a choice. And it’s already happening. 1. For Individuals & Families — Western & Global South 🔹 Short-term: – Escape inflation & currency collapse – Send/receive money without banks – Save in money that holds value over time 🔹 Medium-term: – Build generational wealth in a deflationary asset – Teach kids real financial literacy – Reduce reliance on unstable fiat systems 🔹 Long-term: – True financial sovereignty – No confiscation, no censorship – Plan for the future without fear of debasement > In Lebanon, Nigeria, Argentina — families use BTC to survive. > In the UK, US, EU — they use it to opt out of broken systems. 2. For Businesses — Especially SMEs 🔹 Short-term: – Accept BTC payments with lower fees – Attract global customers – Avoid chargebacks & fraud 🔹 Medium-term: – Hold BTC as a treasury asset – Hedge against inflation & fiat volatility – Pay vendors & staff globally, instantly 🔹 Long-term: – Build on Lightning for microtransactions – Operate borderlessly – Future-proof against central bank instability > Small businesses don’t need Wall Street. > They need stable money, fast payments, and global reach. 3. For Governments 🔹 Short-term: – Diversify reserves beyond USD, GBP, CHF & EUR – Hedge against inflation & geopolitical risk – Attract Bitcoin tourism & investment (see El Salvador 🇸🇻) 🔹 Medium-term: – Reduce reliance on IMF/World Bank debt cycles – Build sovereign wealth in a scarce asset – Enable financial inclusion for the unbanked 🔹 Long-term: – Fiscal discipline: no money printer bailouts – Transparent, auditable reserves – Strategic edge in the digital economy > Bitcoin is not just a hedge. > It’s a foundation for a new kind of governance. 4. Why It Matters Bitcoin is: ✅ Permissionless ✅ Borderless ✅ Scarce ✅ Censorship-resistant ✅ Globally accessible It’s not just a better currency. It’s a better system. #BitcoinStandard #SoundMoney #BTCAdoption

🧵 Why #Fiat #Currency is #Ribawi: 1/ What do you call a system where money is born out of #debt, backed by nothing, and inflated endlessly? Fiat currency. And according to many Islamic scholars: it’s inherently ribawi. Here’s why. 👇 2/ Debt-Driven Creation Fiat isn’t printed out of thin air — it’s loaned into existence. Every pound, dollar, or yen in circulation began as a debt contract. Banks create money when they issue loans, not when governments print notes. 3/ Interest at Its Core (#Riba) That debt accrues interest. Meaning: the money you borrow must be repaid with more. This surplus — interest — is riba, strictly prohibited in #Islam. Fiat requires this process to function. 4/ Perpetual #Inflation Because #money is created with interest, there’s always more debt than currency. To repay old debt, new debt is needed. This leads to inflation, loss of purchasing power, and systemic inequality. A cycle of economic violence. 5/ Money as a Moral Instrument In Islam, money should be a store of value, medium of exchange, and unit of account—without injustice. Fiat violates all three when: - It loses value over time - It’s manipulated through interest - It favours debt-based profit 6/ Who Benefits? Commercial banks, governments, and debt-holders. Who suffers? The poor, the unwaged, and future generations. Fiat channels wealth upward, perpetuating #usury on a global scale. 7/ We Now Have An Alternative Model #Bitcoin can be used to avoid Riba and break free from the logic of debt-based currency. 8/ Fiat ≠ Neutral Many Muslims think using fiat is just “practical.” But we must ask: if the money itself is born in riba, does every transaction carry its stain? This isn’t just economics—it’s ethics. 9/ So What Can We Do? - Learn how fiat works - Educate yourself and your family and opt into Bitcoin as a non-ribawi financial system - Question what we use, not just how we use it 10/ Fiat currency isn’t just inconvenient. It’s a system built on compounding debt and institutionalised riba. As Muslims and people who believe in ethics and justice in money matters, let’s reclaim economic integrity— one concept at a time.

The final installment of our #Bitcoin-inspired cyberpunk fiction is out now! THE LEDGER OF DUST AND LIGHT - Part 3: The Ripple and the Reckoning "The first drone smashed through a reinforced wall with a screech of grinding metal and tearing rock. It was a monstrous, multi-limbed machine, its optical sensors glowing with cold, relentless purpose. They fought back with desperation born of conviction. The clang of metal on metal, the whine of energy weapons, the roar of the drone filled the hab-unit. They were fighting against machines animated by the spirit of Riba, instruments of a system that valued resource extraction and control above all else." 🔗 https://medium.com/@abdul.ashik/the-ledger-of-dust-and-light-5d0fbcc96003

🕶️ Most people aren’t ready to unplug. Because comfort is addictive. Because the system teaches obedience, not freedom. #Fiat isn’t just #money—it’s engineered #debt, #Riba dressed as progress. #Bitcoin asks you to question everything: What is money? Who controls it? Why is perpetual debt normalised? Unplugging isn’t just technical—it’s spiritual. It means rejecting Riba, reclaiming sovereignty, choosing justice. Like Neo hesitating before the red pill, most pause… Not because Bitcoin is unclear— But because truth is terrifying when illusion feels safe. 🧠🔌📀

Read the second part of our exciting new #Bitcoin-inspired cyberpunk short story series. THE LEDGER OF DUST AND LIGHT Part 2: The Crucible of Code "The repurposed hab-unit hummed with a low, resonant energy. Wires snaked across the floor, connecting salvaged power converters to the heart of their operation: a cluster of antique server racks glowing with cool blue light, running parallel processing algorithms that pushed their ancient hardware to the brink. This was their ‘Crucible’, the makeshift data centre where the Anti-Riba Protocol was being tested, refined, and shielded against potential Nexus counter-analysis." https://medium.com/@abdul.ashik/the-ledger-of-dust-and-light-6426defd9fb5

🤔 What does it mean to “orange pill” someone? It is #Bitcoin slang for waking them up to the philosophy, potential, and urgency of Bitcoin — much like Neo taking the red pill in The Matrix, but with a Bitcoin twist. Here’s what it typically means: 🧠 Philosophical Awakening - It’s not just about buying Bitcoin — it’s about seeing the world through a Bitcoin lens. - You help someone recognise the flaws in fiat money: inflation, centralisation, debt-based systems. - They begin to understand Bitcoin as sound money, digital property, or even freedom tech. 🔄 Shift in Perspective - The person starts questioning traditional financial systems and exploring decentralised alternatives. - They might begin learning about low time preference, self-custody, and censorship resistance. 💬 Cultural Meme - The term is inspired by Bitcoin’s orange logo and the red pill metaphor from The Matrix. - Bitcoiners often say things like “I orange-pilled my cousin” — meaning they sparked curiosity or converted someone to the Bitcoin mindset. 🧩 It’s Not One-Size-Fits-All - Some people are orange-pilled by economic instability. - Others by tech innovation, ethical finance, or even spiritual alignment with Bitcoin’s principles. It’s a mix of education, storytelling, and empathy. You’re not just selling an asset — you’re inviting someone to rethink money, power, and possibility. Would you say your own orange pill moment was gradual or sudden?

New Bitcoin-inspired Cyberpunk fiction is out! Overture In the desolate, dusty, low-gravity landscape of Mars, the legend of Satoshi Nakamoto takes on a new life - the digital and physical realms blur. After releasing the revolutionary Bitcoin protocol to the world, Satoshi vanished into the shadows, leaving behind a legacy that would forever alter the course of human history. The year is 2140, all 21 million bitcoin have been mined, and the world is unrecognisable. The over-a-century-old unholy alliance between centralised powers, namely central banks, mega corporations, corrupt politicians and secret agents, all now controlled by an omnipotent Artificial Intelligence named The Nexus. Together, they seek to maintain their grip on the world by suppressing the decentralised revolution that Satoshi Nakamoto sparked. This is a story of censorship resistance, innovation, resilience and the unyielding pursuit of freedom. https://medium.com/@abdul.ashik/the-ledger-of-dust-and-light-41df37abe229 #cyberpunk #sciencefiction #fantasy #islamicfiction #AI
