HashrateUp - A Bitcoin Mining Podcast

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

Understanding Bitcoin Mining doesn’t have to be complicated. In this episode, I break down the entire process using the famous “dice analogy” from Braiins. It’s the simplest way to grasp what miners actually do, why the difficulty adjusts every 2016 blocks, and how Proof-of-Work keeps Bitcoin secure and permissionless.We walk through:• How Bitcoin Mining is basically massive-scale number guessing• Why block time targets stay at 10 minutes• How difficulty goes up or down based on hashrate• Why more miners joining makes the game harder• Why Proof-of-Work can’t be faked• What today’s difficulty adjustment means for miners• Why low hashprice pushes machines offlineBy the end, you’ll understand Bitcoin Mining through a real-world metaphor anyone can follow.If this helped you, share it with someone who wants to understand Bitcoin Mining without the technical jargon.🛠 Sponsored byHashbranch – Hosting & hardware made simple.Code: HASHRATEUP100https://hashbranch.comSoloMining – Home & solo mining made easy.Code: HASHRATEUPhttps://solomining.deAltair Technology – Buy Bitcoin Mining Solutions.https://altair.technology📲 HASHRATEUP HARDWARE DEALSHardware sales, advisory, hosting & site brokerage.Telegram: https://t.me/hashrateup

In this episode, recorded at the Africa Bitcoin Conference in Mauritius, Erik Hersman (CEO of Gridless) breaks down the newly announced open-source Jua Kali miner — a DC Bitcoin miner designed to run directly on 12V solar and turn excess energy into a scalable Solar “Money Battery.”We discuss how Jua Kali repurposes old hashboards, solves the global stranded-solar problem for 5–100 kW sites, and enables farmers, workshops, and rural communities to monetize energy that would otherwise be wasted. In the second half of the conversation, Blaise from the Gridless engineering team opens the unit and explains the full hardware stack so anyone can build, adapt, and deploy it using off-the-shelf components.Topics include decentralized mining, second-life ASIC hardware, rural electrification, small-scale solar economics, and how open-source hardware could spread Bitcoin mining across Africa and the world.Sponsored byHashbranch – Hosting & hardware made simple.Code: HASHRATEUP100https://hashbranch.comSoloMining – Home and solo mining made easy.Code: HASHRATEUPhttps://solomining.deAltair Technology – Buy Bitcoin mining solutions.https://altair.technologyHashrateUp Hardware DealsTelegram: https://t.me/hashrateupFollow HashrateUpWebsite: https://hashrateup.comSpotify: https://open.spotify.com/show/6At5Inqb2JHVl4k9VuPO8tTwitter: https://twitter.com/HashrateUpInstagram: https://www.instagram.com/hashrateupbtc/TikTok: https://www.tiktok.com/@hashrateupLinkedIn: https://www.linkedin.com/company/hashrateup

Firmware has become one of the most important levers for miners operating in today’s low-hashprice environment — and in this HashrateUp Focus episode, Jesse breaks down exactly why.He explains how firmware fundamentally changes the way an ASIC performs its calculations, why underclocking can keep older-gen machines profitable, and how overclocking unlocks additional revenue when market conditions improve. Using BrainsOS and LuxOS as concrete examples, Jesse compares default firmware to custom setups and shows how miners can improve efficiency, boost hash-rate output, and optimize joules per terahash with just a simple software flash.The episode also covers warranty considerations, dev-fee economics, pool discount structures, and why hosters can often install firmware for you with minimal downtime. From S19J Pro tuning to squeezing extra performance out of S21 units, this breakdown gives miners a practical framework for deciding when custom firmware makes sense — and how to use it responsibly.Whether you’re running a single machine at home or optimizing a larger fleet, this episode offers a clear, actionable guide to extracting more value from your ASICs.🛠 Sponsored byHashbranch – Hosting & hardware made simple.Code: HASHRATEUP100https://hashbranch.comSoloMining – Home & solo mining made easy.Code: HASHRATEUPhttps://solomining.deAltair Technology – Buy Bitcoin Mining Solutions.https://altair.technology📲 HASHRATEUP HARDWARE DEALSHardware sales, advisory, hosting & site brokerage.Telegram: https://t.me/hashrateup
