HashrateUp - A Bitcoin Mining Podcast

In this HashrateUp Focus episode, Jesse breaks down how Bitcoin miners are actually built — using a real Antminer S9 and modern ASIC designs to explain what’s inside a mining machine.The episode walks through the core components of an ASIC miner, including the chassis, airflow, fans, control board, firmware, power delivery, hashboards, and the individual ASIC chips themselves. Jesse explains how air cooling works, how control boards manage hashboards, and why chip density and layout matter for thermal performance.The second half compares older-generation miners with modern designs, covering integrated power supplies, hot-swappable fans, removable hashboards, and modular layouts that improve reliability and serviceability.This episode is a hardware-first explainer for anyone who wants to understand Bitcoin mining beyond hash rate and efficiency numbers — from beginners to experienced operators looking for a clearer mental model of ASIC hardware.🛠 Sponsored byHashbranch – Hosting & hardware made simpleCode: HASHRATEUP100https://hashbranch.comSoloMining – Home & solo mining made easyCode: HASHRATEUPhttps://solomining.deAltair Technology – Buy Bitcoin Mining Solutionshttps://altair.technology📲 HashrateUp Hardware Deals💬 Telegram: https://t.me/hashrateup🌐 Website: https://hashrateup.com🐦 Twitter: https://twitter.com/HashrateUp📸 Instagram: https://www.instagram.com/hashrateupbtc/🎵 TikTok: https://www.tiktok.com/@hashrateup💼 LinkedIn: https://www.linkedin.com/company/hashrateup

In this HashrateUp FOCUS episode, Jesse explains demand response from the ground up — and why it has become one of the most critical concepts for modern electricity grids.The episode begins with the fundamentals: why electricity must be consumed the moment it’s generated, how grid frequency reflects the balance between supply and demand, and what actually causes blackouts and cascading grid failures.Jesse then connects these concepts to today’s reality: grids with growing shares of wind and solar, wasted energy through curtailment, costly grid interventions, and real-world examples such as load shedding in South Africa and blackouts in Europe.Finally, the episode explains why Bitcoin mining is uniquely suited for demand response. Instant flexibility, fast shutdowns, location independence, high power density, and the ability to monetize electricity without traditional infrastructure make Bitcoin mining a grid tool unlike any other.This episode is designed to give you a clear, intuitive understanding of demand response — without assuming prior knowledge of energy markets or grid engineering.🛠 Sponsored byHashbranch — Hosting & hardware made simpleCode: HASHRATEUP100👉 https://hashbranch.comSoloMining — Home & solo mining made easyCode: HASHRATEUP👉 https://solomining.deAltair Technology — Buy Bitcoin mining solutions👉 https://altair.technology📲 HashrateUp Hardware Deals💬 Telegram: https://t.me/hashrateup🌐 Website: https://hashrateup.com🐦 Twitter: https://twitter.com/HashrateUp📸 Instagram: https://www.instagram.com/hashrateupbtc/🎵 TikTok: https://www.tiktok.com/@hashrateup💼 LinkedIn: https://www.linkedin.com/company/hashrateup

Recorded live at the Africa Bitcoin Conference in Mauritius, Jesse sits down with Skot, the instigator of the Bitaxe project, to discuss why open source could become the most important frontier in Bitcoin mining.The conversation explores both the philosophy and the practical realities of open-source mining hardware and firmware. Skot explains how Bitaxe began as a personal side project, why he chose to open-source the entire stack, and how it unexpectedly evolved into a global ecosystem with manufacturers, builders, and tens of thousands of devices in the wild.They talk about why large miners increasingly want full firmware control, how proprietary firmware creates hidden operational risks, and why open source aligns more naturally with Bitcoin’s incentive structure. The episode also touches on solar and off-grid mining in Africa, second-life ASICs, home mining, competition among miner manufacturers, and how Bitmain’s dominance shapes the industry.This episode is for anyone interested in Bitcoin mining, open-source hardware, firmware sovereignty, and the long-term resilience of the Bitcoin network.🛠 Sponsored byHashbranch — Hosting & hardware made simpleCode: HASHRATEUP100👉 https://hashbranch.comSoloMining — Home & solo mining made easyCode: HASHRATEUP👉 https://solomining.deAltair Technology — Buy Bitcoin mining solutions👉 https://altair.technology📲 HashrateUp Hardware Deals💬 Telegram: https://t.me/hashrateup🌐 Website: https://hashrateup.com🐦 Twitter: https://twitter.com/HashrateUp📸 Instagram: https://www.instagram.com/hashrateupbtc/🎵 TikTok: https://www.tiktok.com/@hashrateup💼 LinkedIn: https://www.linkedin.com/company/hashrateup

In this HashrateUp Focus episode, Jesse breaks down one of the most fundamental concepts in Bitcoin mining: what a hash actually is.Building on the previous Focus episode about the dice-roll analogy and difficulty adjustment, this episode explains how SHA256 hashing works and why Bitcoin mining is essentially large-scale brute-force guessing.You’ll learn:What a hash is and why it’s one-wayHow SHA256 is used everywhere on the internetWhy miners make trillions of guesses per secondWhat a nonce is and why it keeps changingWhy valid Bitcoin blocks need hashes with leading zerosHow proof of work is verified by the networkThis episode is designed to give you an intuitive, practical understanding of how hashing powers Bitcoin mining, without unnecessary math or jargon.If you’re new to Bitcoin mining, make sure to listen to the previous Focus episode first — both episodes are meant to be consumed together.🛠 Sponsored byHashbranch – Hosting & hardware made simpleCode: HASHRATEUP100https://hashbranch.comSoloMining.de – Home & solo mining made easyCode: HASHRATEUPhttps://solomining.de📲 HashrateUp Hardware DealsTelegram: https://t.me/hashrateup🌐 Website: https://hashrateup.com🐦 Twitter: https://twitter.com/HashrateUp📸 Instagram: https://www.instagram.com/hashrateupbtc/🎵 TikTok: https://www.tiktok.com/@hashrateup💼 LinkedIn: https://www.linkedin.com/company/hashrateup

In this episode of HashrateUp, Jesse sits down with Jaran Mellerud from Hashlabs, to break down what actually determines mining profitability in 2025: hashprice pressure, realistic ROI modeling, heat reuse constraints, demand response tradeoffs, ASIC pricing (USD vs BTC), and why “tax tricks” don’t replace a real edge.Jaran also explains why Finland is one of the best risk-adjusted places to mine if you can sell heat into district heating networks — and why the industry is converging toward two survival models: deep energy integration in the West vs. structurally advantaged large-scale miners in emerging markets.Guest: Jaran Mellerud (Hashlabs)🌐 Hashlabs: https://hashlabs.io🐦 X: https://x.com/jmellerud🛠 Sponsored byHashbranch – Hosting & hardware made simple.Code: HASHRATEUP100👉 https://hashbranch.comSoloMining – Home & solo mining made easy.Code: HASHRATEUP👉 https://solomining.deAltair Technology – Buy Bitcoin Mining Solutions.👉 https://altair.technology📲 HASHRATEUP HARDWARE DEALS💬 Telegram: https://t.me/hashrateupFOLLOW HASHRATE UP🌐 Website: https://hashrateup.com🎧 Spotify: https://open.spotify.com/show/6At5Inqb2JHVl4k9VuPO8t🐦 Twitter: https://twitter.com/HashrateUp📸 Instagram: https://www.instagram.com/hashrateupbtc/🎵 TikTok: https://www.tiktok.com/@hashrateup💼 LinkedIn: https://www.linkedin.com/company/hashrateup
