In this HashrateUp Focus episode, Jesse explains what mining shares are, why pools use them, and how stale and rejected shares directly impact miner payouts.
The episode breaks down how pools verify work without checking every hash, what causes stale shares, and why share efficiency is a key metric for running a clean and profitable mining operation.

🚀 Why Stratum V2 Matters for Bitcoin Mining
In this episode of HashrateUp, Jesse speaks with Pavel Moravec, co-creator of Stratum and long-time Stratum V2 contributor, and Gabriele, lead maintainer of the Stratum V2 Reference Implementation (SRI), about why Stratum V2 is one of the most important infrastructure upgrades in Bitcoin mining.
Stratum V2 is the upgrade to the original Stratum (SV1) mining protocol from 2011. It is designed for modern mining operations and improves efficiency, security, privacy, and miner autonomy — without changing Bitcoin’s consensus or the pooled mining model.
⚡ What Stratum V2 improves
Efficiency ⚙️ – ~60% less bandwidth for pools, ~70% less for miners, lower latency, fewer stale shares
Security & privacy 🔐 – Encrypted mining traffic, protection against hashrate hijacking and ISP surveillance
Miner autonomy 🧱 – Optional miner-built block templates, reduced pool single points of failure
Production-ready 🏗️ – Backwards compatible, native Bitcoin Core v30+ support, works with all payout models
📈 Real-world case studies show profit increases of up to 7.4%, alongside major gains in operational security and efficiency.
🧩 What is SRI?
SRI (Stratum Reference Implementation) is the free, open-source, production-grade implementation of Stratum V2.
MIT-licensed, vendor-neutral, maintained by an independent industry working group.
Version 1.0 released in March 2024 and already live or being tested by major miners, pools, and firmware providers.

📄 NiceHash Annual Bitcoin Mining Report
👉 https://www.nicehash.com/annual-bitcoin-mining-report
In this episode of HashrateUp, Jesse sits down with Nico Smid, founder of Digital Mining Solutions, to break down the NiceHash Annual Bitcoin Mining Report and what it reveals about the current state of Bitcoin mining.
They unpack key insights from the report, including hashrate growth, compressed hashprice, ASIC pricing dynamics, manufacturer self-mining, and why AI and HPC competition is pushing miners toward the fringes of the energy system.
Topics covered include:
Why mining economics remain under pressure

What falling ASIC prices really mean for operators

Public vs private miners and consolidation risk

Why solo mining and home mining still matter

How the next halving could impact hashprice and miner behavior

This episode is a data-driven deep dive into Bitcoin mining fundamentals — not narratives.

In this episode of HashrateUp, Jesse sits down with Kris Konicki from Altair Tech to break down what it really means to scale past home mining and turn Bitcoin mining into a serious investment.
They walk through Altair’s typical customer journey — from first exposure via small home miners like the Nano or Avalon Q, to deploying real capital into hosted or larger-scale operations. Kris explains why education, hands-on experience, and transparency matter before committing meaningful money to mining.
The conversation also covers current network conditions, hashrate stagnation, limited visibility outside North America, and how new hardware releases can distort short-term hashrate trends. On the hardware side, Kris shares which ASICs sold best in 2025, why efficiency mattered more than raw hashrate this cycle, and why consumer-friendly home miners are becoming a critical on-ramp for new operators.
Topics include:
Scaling beyond home mining without getting burned

Why 120V mining matters and what the trade-offs are

Inventory risk, tariffs, and hardware price volatility

Why Altair avoids Telegram and WhatsApp backdoor sales

Supplier selection, RMAs, and parts strategy

Education as the bridge from hobby mining to real investment

This episode is for miners who are done experimenting and are thinking seriously about capital allocation, infrastructure, and long-term participation in Bitcoin mining.

In this episode of HashrateUp, Jesse sits down with Alen Makhmetov, Co-Founder of Hashlabs, to unpack what Bitcoin mining in Russia actually looks like beyond headlines and speculation.
Alen shares firsthand experience operating mining infrastructure across Kazakhstan, Russia, and Northern Europe. He explains how mining regulation evolves in practice: rising power prices, changing tax regimes, import duties, curtailment, FX risk, and why governments rarely ban mining outright — instead, they make it gradually unprofitable.
In the second half, the conversation goes deep into Bitcoin mining heat reuse. Using real-world projects in Finland, Alen breaks down how miners integrate with district heating systems, why sites must be sized to summer baseload demand, and why 80°C heat output is the critical threshold for making heat reuse economically viable at scale.
