| 4 |  Braiins OS. Ethernet. Southwest Airlines. Messi’s first contract with FC Barcelona.
What do they all have in common?
They all started with a napkin.
Eight years ago, our co-founder Jan Čapek was sitting in a Prague restaurant with his baby son and Marian, our ASIC/FPGA guru.
They wanted to give the stock firmware monopoly some real competition.
Beer in one hand, baby in the other, Jan started sketching how their own firmware could work.
“Tough beginnings, I would say,” Jan recalls.
One month later, Braiins OS was released.
Eight years on, Braiins OS runs on 3 GW+ of machines, helping their owners mine more bitcoin.
Here’s to many more 🍻🍼

| 7 |  📣 Braiins Toolbox 26.08 is out
This release brings a faster device list, support for more miners, and a native Apple Silicon build.
What’s new:
1️⃣ Faster device list. Filtering, sorting, and search now happen on the backend and update live. This keeps Toolbox responsive even with large fleets.
2️⃣ More miner support. Toolbox now supports Auradine Teraflux miners and Antminers running MARAFW in both the CLI and GUI.
3️⃣ Native Apple Silicon build. Toolbox now runs natively on M-series Macs.
4️⃣ Better scans. You can cancel a scan before it finishes. Scans also no longer conflict with actions already running on the same devices.
🍏 Mac users: Toolbox 26.08 supports Apple Silicon only. Existing macOS installations cannot detect this release through the in-app updater, so download the new build manually. Intel Macs are no longer supported.
Download Braiins Toolbox for free 🔥 | 1 695 |
| 8 |  UPGRADE: Braiins OS 26.08 is live 💥
New hashboard health view, redesigned graphs, and support for the S21++.
1️⃣ Hashboard health overview
• New table shows the health of every hashboard at a glance
• Chip level data for each board, no digging through logs
• Spot a failing board before it costs you hashrate
2️⃣ Redesigned dashboard graphs
• History now persists, so you can look back instead of starting from zero
• Time range selector from 10 minutes up to 7 days
• New power graph and a new overall status graph
3️⃣ New hardware support
• Antminer S21++
• Antminer S19j XP hashboard variant BHB56807
4️⃣ Miner status reporting. The GUI and Public API now tell you why a miner is stopped, starting, or stopping. No more guessing.
5️⃣ Refitted power and efficiency models for the S19 XP Hyd, S19 XP+ Hyd, S19 Pro+ Hyd and U3S21EXPH. These miners will retune after upgrading to pick up the new optimizations.

| 10 |  Did Braiins spam bitcoin?
Since 2010, our job has been simple: help miners mine more bitcoin.
But every once in a while, we’ve used a block to mark something worth remembering:
668,634 · Clubhouse 31/Jan/2021 I am a supporter of Bitcoin ... Elon Musk
671,176 · 18/Feb/2021 NASA Perseverance and Ingenuity landed on Mars
686,604 · Diario El Salvador 6/Jun/2021 Bitcoin tendra validez legal
785,389 · This block was mined by a zero emission bitcoin mining computer.
824,131 · Happy 15th birthday, Bitcoin!
Then our CMO, Kristian, made one personal.
883,395 · Will you be my queen, Summer?
Her answer:
885,166 · 883,395 - YES
Congratulations, Kristian and Summer.
Block 883,395 will always be one of our favorites 🧡 | 1 520 |

| 13 | Braiins Pool Networking Outage ⚠️
We're experiencing partial networking issues with our hosting provider, causing the Pool website to fail to load. Share collection is not affected; mining continues as normal. We don't have a timeframe yet, and this may delay payouts for today.
We'll update you as soon as the issue is resolved. | 62 |

| 15 |  Off-Grid mining is seriously cool.
Today’s case study comes from Barefoot Mining.
They run 10+ off-grid sites across the US where power is limited, temperatures are extreme, and machine repairs can mean long trips to remote locations.
This is exactly where running the right firmware matters.
Barefoot tested Braiins OS on S19J Pro+ hardware at one site.
⚡️ After experiencing the performance gains, they rolled Braiins OS out across all of their sites.
Braiins OS helped them:
• Control power use per machine
• Keep miners hashing optimally in high heat
• Shut off damaged hashboards while keeping the machine online with the good hashboards
🟧 In simple terms, Braiins OS helped Barefoot mine more bitcoin without buying new machines or upgrading site infrastructure.
Read the full case study for more on how Barefoot keeps its remote sites hashing with Braiins OS, and how Braiins OS could do the same for yours:
