🚀 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 ⚙️
Stratum V2 reduces bandwidth usage by roughly 60% for pools and 70% for miners.
It replaces JSON with a binary protocol and uses push-based job delivery, resulting in lower latency and fewer stale shares.

Security & privacy 🔐
Mining traffic is fully encrypted.
This prevents hashrate hijacking, credential interception, ISP inspection, and network-level attacks.

Miner autonomy (optional) 🧱
Miners can optionally build their own block templates.
Pools remain in place, but miners gain more control and reduce single points of failure.

Production-ready 🏗️
Stratum V2 is backwards compatible via translation proxies.
It has native support in Bitcoin Core v30+ and works with all common pool payout models such as FPPS and PPLNS.

📈 Real-world case studies show profit increases of up to 7.4%, alongside significant improvements 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 and vendor-neutral
• Maintained by an independent industry working group
• Version 1.0 released in March 2024
• Already live or being tested by major miners, pools, and firmware providers

Timelapse of the Sun in the West, one picture every 24 hours. Watch as the Sun traces out a figure 8 in the sky each year from 2015 to 2018. The shape of this path is known as the solar analemma.

Why does the position of the Sun change each day? The Earth spins and revolves around the Sun, but the Earth's spin is tilted compared to its orbit. Sometimes the Earth's North Pole tilts toward the Sun, and sometimes it tilts away. This makes the Sun appear to shift North and South from one day to the next and creates the north-south motion in the analemma.

It takes the Earth about 23 hours and 56 minutes to spin once, but because it is also moving in its orbit, the Earth has to spin a few minutes more for the same side to face the Sun. The Earth's orbit is elliptical, and the Earth moves faster in its orbit when it is closer to the Sun. So sometimes the Earth has to spin more to return the same side to face the Sun, and sometimes it takes less time. This creates the east-west motion in the analemma.

This video was made from a series of pictures that were each taken 24 hours apart by the HPWREN cameras at the Mount Laguna Observatory in San Diego County over a 3 year period.

Fun fact:
Sawdust has a carbon to nitrogen ratio of about 400:1, the highest of any material.
It makes it perfect for eg. composting toilets, or any composting of high nitrogen to carbon ratio materials (like food waste) without foul odours.
