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

**PUZZLE CARD WORKSHOP - FREE EVENT - ARTS & CRAFTS!** February 26 Přístav 7, Holešovice (V Přístavu 24) From 7:00 PM Before love notes were instant, they were folded. Carefully. With intention. In the 18th and 19th centuries, people used Victorian puzzle purses to hide poems, romantic messages, and tiny keepsakes — sometimes even a lock of hair — inside beautifully folded paper. You had to open them step by step to get to the heart of it. The idea comes from Japanese Tato origami, and later became a popular (and very personal) way to court in England and America. No envelopes, no seals — just clever folds keeping the secret safe. In this workshop, we’re giving this old tradition a modern life. You’ll make your own puzzle purse using beautiful paper, and turn it into a card, a love note, or a small gift wrapper that actually feels special. No experience needed. Just hands, paper, and a bit of curiosity.
