Bitcoin Knots a podobné implementace se snaží vynucovat content policy na úrovni mempoolu a odmítají transakce považované za nežádoucí (označované za spam). Lukáš, náš expert na Rust a bitcoin, vám osvětlí tento problém v teorii i v praxi. **🦀 18:00 - 19:00: PREZENTACE** Tato přednáška vysvětluje, proč je filtrování transakcí na základě obsahu neúčinné v jakékoli vrstvě bitcoinového protokolového stacku. Představí dva vzájemně se doplňující argumenty. 1. Z pohledu topologie sítě: v gossip síti, kde i malá menšina uzlů zůstává permisivní, transakce s vysokou pravděpodobností obejdou filtrované uzly. 2. Z pohledu informační teorie: každý protokol, který je dostatečně expresivní, aby byl užitečný, nutně umožňuje steganografické kódování. Prostor platných transakcí je natolik velký, že do něj lze vložit libovolná data způsobem nerozlišitelným od běžné ekonomické aktivity. Filtrování na základě obsahu tak čelí protivníkovi s větším počtem stupňů volnosti než má samotný filtr. **🦀 19:00 - 19:30: LIVE DEMO + Q&A** Součástí prezentace bude živá ukázka agresivního relay uzlu napsaného v Rustu, běžícího na mainnetu, která v reálném čase ukáže tok transakcí napříč různými implementacemi uzlů. **🦀 19:30** **\- 22:00: NETWORKING** Po přibližně 60minutové prezentaci a Q&A zůstáváme na networking u piva, zhruba do 22:00. * **Vstup s registrací zdarma.** * **Pivo zdarma** pro prvních 50 hostů. * **Odměny** za nejlepší otázky. * **Knihy** od Braiins **zdarma**. **🦀 PŘEDNÁŠEJÍCÍ** Lukáš Hozda je expert na Rust, autor knihy Building Bitcoin in Rust a lektor Rust kurzů na Univerzitě Karlově. Přes den pracuje v pražské bitcoinové softwarové společnosti Braiins, kde jeho oficiální pracovní titul zní Braiins Superman. * Stáhněte si jeho eBook [Building Bitcoin in Rust zdarma](https://braiins.com/books/building-bitcoin-in-rust). * Sledujte Lukáše na X: [https://x.com/LukasHozda](https://x.com/LukasHozda) Pokud vás zajímá seriózní Rust engineering, přidejte se k nám. 🔗 https://braiins.com

This session turns to the epicenter of Milton’s poem: temptation, choice, and consequence. In Books IX and X, the Fall finally unfolds, and with it the unraveling of innocence, intimacy, and cosmic order. We’ll read closely and ask difficult questions. What actually changes in Adam and Eve? Is the Fall a tragedy, a liberation, or something more complicated? Where does responsibility truly lie? And how does Milton want us to judge - or not judge - what happens? As always, this is a shared inquiry discussion. No lectures, no summaries. Just careful reading, real questions, and collective thinking around the table. Come ready to wrestle with the text.

An immersive evening created by the Czech Expat Club to move out of the dark Czech winter and back into light. We begin with grounding yoga, followed by a cacao ceremony, and then a full ecstatic dance journey. No choreography, no phones, no talking on the dance floor. Move how you feel. Food, drinks, and a curated pop up market outside the space. Come as you are. Move freely.

Some people go to pubs. Some people conquer galaxies, build empires, trade spices, or outsmart dragons. Nerdy Fridays are our open board game nights for anyone who prefers strategy over small talk and dice over disco lights. Come solo or bring your crew.

There is a small organisation fee of 20 crowns for all players to participate in this event. Racquets can be rented for 50 crowns.

(Note: RSVPing here on meetup does NOT reserve your seat. To do that, you’ll need to register at our website, **[HERE](https://www.coreerocks.com/Events.aspx?ID=Columbus-in-person-chapter-meeting-Your-2026-Buy-Box-Successful-Rentals-101-14-3-3-2026)**.) Let’s be honest. In 2026, you can’t use 2023 strategies and “hope” a deal works out. Demand for rentals, wholesale deals, retail deals, and even loans has changed, and that means that the most active, experienced investors have changed the way they do deals (and maybe even the kinds of deals they’ll do). Here at COREE, our job is to shortcut your learning curve by introducing you to the people and concepts you need to take the shortest path from here to financial freedom, and we think you’ll agree that this meeting is a no-brainer, if you’re serious about making wealth-building deals this year. Here’s the detailed agenda: From 6:00–7:00 p.m., From 7:30–9:00 p.m., Agenda: 5:00–6:00 p.m. Complimentary Light Dinner & Networking 6:00–7:00 p.m\*\*. New Investor Meeting: Basics of Making Money in Rentals with Vena Jones-Cox\*\*. If you’re planning to buy rentals today, you have to know how to evaluate the REAL income and expenses before you make an offer. If you’re new, you’ll finally understand how rentals really produce profit. If you’ve been around a while, you’ll see how today’s numbers change the math. 7:00 –7:30 **Buy-Sell-Trade (Members Only)** Bring your deals, money, buyer lists, referrals, and requests. Fast-moving. Bring flyers or business cards. Guests get a quick orientation with Executive Director Vena Jones-Cox. 7:30–9:00 p.m. **Main Meeting: Your 2026 Buy Box: What Experienced Investors are Buying in 2026 (and what they won’t touch).** Our panel of active, experienced investors will lay out their 2026 buy boxes. Not hypotheticals. Not “in theory.” What they are actually buying—and what they won’t touch. They’ll share: * What property types investors are actively pursuing * What strategies they’ve stopped using * The exact numbers they require before they say yes * How insurance, taxes, and rates have tightened the buy box * What instantly disqualifies a deal in today’s market * How to define your own 2026 buy box based on capital and risk tolerance Members and non-members at any level of knowledge and experience are welcome—as long as you’re serious about real estate, value experience-based, no B.S. education, and want to give as much as you get.
