HashrateUp - A Bitcoin Mining Podcast

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...

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...

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...

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: h...

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 m...

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...

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...

Finland is emerging as one of the most attractive Bitcoin mining destinations in the world — and in this episode, Jesse sits down with Daniel Jonsson (MGMT) to unpack why. They discuss how Finland’s unique energy mix of 41% nuclear baseload, fast-growing wind capacity, and strong hydro creates some of the most miner-friendly power dynamics in Europe. Daniel explains how flexible operations and grid balancing can outperform traditional 100% uptime mining, why older-gen ASICs suddenly make sense again, and how miners can benefit from zero or even negative power prices. The conversation explores Finland’s development pipeline, second...

Hashprice is down, Bitcoin is under $100k, and many miners are stressed. In this episode, Jesse talks with Tom Merkle from Hashbranch about how good operators survive these conditions — and why low hashprice can actually create better entry points. (At release, hashprice even sits at $36/PH/day — Nov 20, 2025.) Tom explains what Hashbranch really does for hosting sites: filling rack space, handling support tickets, coordinating deployments, and fixing the communication problems that often hurt both hosts and clients. They also walk through the “core four” of mining: planning your numbers, finding the right host, getting machines set up the righ...

In this HashrateUp Focus episode, Jesse wraps up the Proof of Prudence framework with the final three rules every miner needs to master: precision billing, affordable repairs, and choosing the right pool.
