About us
We are a software, energy, and finance company founded in 2010.
We build infrastructure across bitcoin mining, energy systems, and financial markets. Our work spans from firmware running directly on ASIC miners to mining pool infrastructure and large-scale fleet management software. Over time, we expanded into energy and capital markets.
We organize different types of events throughout the year: technical, business, and educational.
THE EVENTS WE HOST
🟧 1. Industry Networking
- Meetups around conferences and local hubs bringing together miners, operators, manufacturers, energy professionals, and investors.
🟧 2. Technical Lectures
- Focused sessions on systems we build and operate: firmware, distributed architecture, mining stack design, performance optimization, reliability, and energy integration.
🟧 3. Educational Events
- Structured talks for those who want a solid understanding of bitcoin mining, energy, and capital markets. We publish industry books and make selected resources available for free https://braiins.com/books
We do not run a single format. Events vary by topic and audience.

Analýza BIP-110: Časová osa, detaily a dopady. Může to fungovat? 🇨🇿
ambasáda.cz, Pod kaštany 12, Praha, CZPřed několika měsíci vyústila vyostřená debata o filtrech a Core vs Knots v kontroverzní návrh BIP-110, původně známý jako “BIP-444”, neboli Reduce Data Temporary Soft Fork, který má za cíl dočasně omezit časté způsoby vkládání netransakčních dat na bitcoin. Je tento návrh efektivní? Jaké kroky navrhuje? Co se musí stát pro jeho aktivaci a jaká je situace dnes?
Lukáš, náš expert na Rust a bitcoin, vám podrobně přiblíží tento problém z každého hlediska.
🦀 PREZENTACE
Tato přednáška představuje BIP-110 v kontextu debaty Knots VS Core, tedy o spam filterech. BIP-110 se snaží se vypořádat se s domnělým i reálným spamem změnou pravidel Bitcoin konsensu, tím že zakáže použití určitých op-kódů a omezí maximální velikosti dat u jiných opcodes. Na BIP-110 se podíváme- Z pohledu technického: Co přesně se snaží změnit a proč, kterým metodám se snaží zamezit, a zda zabraňuje některým legitimním použitím bitcoinu
- Z pohledu časové osy a komunity: Kdy a kým byl BIP-110 vytvořen, kdy se aktivuje a jaké podmínky pro aktivaci musí splnit, jak fungují User-Activated Soft Forky, co se může stát, pokud k jeho aktivaci dojde, a co se může stát, pokud ne
- Z pohledu efektivity: Jak zapadá do existujících způsobů vkládání netransakčních dat na blockchain, kterým způsobům nezamezuje, a jak se to projeví na ceně vkládání dat
🦀 NETWORKING
Po přibližně 60minutové prezentaci a Q&A zůstáváme na networking u piva. Zůstáváme do 22:00.- Registrace je zdarma.
- Bude pití i něco k jídlu.
- Odměny za nejlepší otázky.
- Knihy od Braiins zdarma.

ENGLISH 🇺🇸
Analysis of BIP-110: Timeline, Details and Impacts. Can it work?
A few months ago, a heated debate about filters and Core vs Knots culminated in the controversial proposal BIP-110, originally known as 'BIP-444', or Reduce Data Temporary Soft Fork, which aims to temporarily restrict common methods of inserting non-transactional data onto Bitcoin. Is this proposal effective? What steps does it propose? What needs to happen for it to be activated, and what is the situation today?
🦀 THE PRESENTATION
This lecture presents BIP-110 in the context of the Knots vs Core debate, specifically about spam filters. BIP-110 attempts to deal with both alleged and real spam by changing Bitcoin consensus rules, by banning the use of certain op-codes and restricting the maximum data sizes of other opcodes. We will look at BIP-110 from:- A technical perspective: What exactly it tries to change and why, which methods it tries to prevent, and whether it blocks some legitimate uses of Bitcoin
- A timeline and community perspective: When and by whom BIP-110 was created, when it activates and what conditions it must meet for activation, how User-Activated Soft Forks work, what may happen if it is activated, and what may happen if it is not
- An effectiveness perspective: How it fits into existing methods of inserting non-transactional data onto the blockchain, which methods it does not prevent, and how this will be reflected in the cost of inserting data
🦀 THE NETWORKING
After about a 60min presentation and Q&A we will stay to network over a beer, we stay until 22:00.- Register here for free entry.
- Drinks and snacks provided.
- Giveaways for the best Q&A questions.
- Braiins Bitcoin books for free.
