Bisq: Bitcoin kaufen ohne KYC 🛡️
Du kaufst Bitcoin weil du frei sein willst. Raus aus dem kaputten Fiat-System, weg von der Kontrolle der Zentralbanken. Und was ist dein erster Schritt in diese angebliche Freiheit? Du scannst deinen Reisepass ein, machst ein braves Selfie für den Ident-Check und lädst beides bei einer zentralen Börse hoch. Fällt dir was auf?

Twenty-Four Words for an nsec
Every Nostr private key ever generated can be losslessly encoded as twenty-four words, recovered byte-for-byte forever, stamped onto Bitcoin steel plates.

Tails OS: The Amnesic OS for Digital Freedom
Every operating system you use leaves a trail. Browser history, file access logs, network connections, swap files — your computer is a diary you never meant to keep. Tails is the answer to that problem: a live operating system that remembers nothing, routes everything through Tor, and disappears without a trace the moment you pull the USB stick.

Tor Browser & Orbot: How to Disappear on Android
Your ISP sees everything you do online. A VPN just moves the problem. Tor eliminates it — by design, not by trust. Here's how Tor Browser and Orbot work, when to use which, and how to route your Bitcoin wallet through Tor.
Engpass — über die Architektur der Kontrolle
Überwachung braucht keine Totalerfassung. Ein einziger Datenpunkt am Eingang reicht. Warum Bitcoin und Nostr genau dieses Muster adressieren — und was das strukturell bedeutet.

Bitcoin-Privacy-Techniken: CoinJoin, PayJoin & Co. richtig kombinieren
CoinJoin allein reicht nicht. Welche On-Chain- und Off-Chain-Techniken es gibt, wie du sie kombinierst, welche Wallets wirklich privat sind – und die häufigsten Fehler, die einen guten Mix wieder zunichtemachen.

Nostr and Tor Against Big Data and Techno-Feudalism
Nostr and Tor are the architectural answer to techno-feudalism. On decentralization, cryptographic identity, and escaping Big Data's feudal grip.

Group messaging without a central server is a consensus problem. We stopped patching the symptoms and rebuilt the protocol from the state machine outward. Here's the full story.

European Parliament approves digital euro: introduction in 2029 one step closer

„Ich hab doch nichts zu verbergen“ – warum dieser Satz gefährlicher ist, als du denkst
Wer nichts zu verbergen hat, hat auch nichts zu befürchten? Die Wissenschaft sagt etwas anderes: Schon das Gefühl, beobachtet zu werden, verändert unser Verhalten – und unser Denken. Vom Panoptikum über das Asch-Experiment bis zu den messbaren Chilling-Effekten nach Snowden: Warum Überwachung uns alle verändert, ohne dass wir es merken.

How Nostr Chats Really Work
Ever wondered how private chats work on a public, decentralized network? This deep‑dive explains Nostr Kind‑4 (NIP‑04) encrypted direct messages – from the ECDH shared secret to AES‑256‑CBC encryption – and reveals what’s truly private (content) vs. what’s still public (metadata).

Dreimal abgelehnt, trotzdem beschlossen: Was die Chatkontrolle für deinen Messenger bedeutet
Am 9. Juli 2026 hat das EU-Parlament die Chatkontrolle passieren lassen – nachdem es sie dreimal abgelehnt hatte. Was wirklich beschlossen wurde, warum sich für Signal nichts ändert und was du jetzt in Ruhe tun kannst.
Zapstore: The Open App Store Built on Nostr
For decades the gate has been the same. A handful of corporations decide what software you are allowed to run. They sit between you and the developer. When an app vanishes, there is no explanation and no appeal. You are forced to trust a supply chain with hands you never see.

Warum dein Smartphone dir nicht gehört – und was Bitcoin damit zu tun hat
Du hast dein Handy bezahlt – trotzdem entscheidet ein Konzern, welche Software darauf laufen darf. Was Eigentum wirklich bedeutet, warum Googles neue Regeln das Gerät zur Leihgabe machen und weshalb Bitcoin-Sparer diese Frage längst kennen.

Die häufigste Sorge vor dem Umstieg auf GrapheneOS: Läuft meine Banking-App noch? Die kurze Antwort ist meistens ja. Wir erklären, warum manche Apps trotzdem zicken, was Play Integrity damit zu tun hat und wie du dein Setup zum Laufen bekommst.

Googles Developer Verification: Ist GrapheneOS betroffen?
Google will ab 2026 verlangen, dass sich alle App-Entwickler registrieren – sonst lässt sich ihre App nicht mehr installieren, auch nicht per Sideloading. Die Kampagne Keep Android Open läuft dagegen Sturm. Aber gilt das auch für GrapheneOS? Und rettet das Motorola-Handy alles? Eine nüchterne Einordnung.

GrapheneOS vs. /e/OS vs. LineageOS: Der Vergleich 2026

AI claimed four of nine releases, all framework or library patches. No models. Privacy logged Whonix and Proton Mail Android. Nostr shipped Zap Store 1.1.0 with device keys and background auto-updates, plus a Mostrix point release. Bitcoin contributed a single Ledger Live Desktop build. The day carries no protocol changes, no security advisories, no Lightning. Operators running Mistral tooling, llama.cpp, or Buffa have updates staged.

Fri, Jul 17, 2026
AI claimed half the wire, shipping six infrastructure releases spanning model runtimes, CLI tooling, and mobile SDKs. No model weights, no protocol changes. Privacy logged three items: FreeTube shipped feature work, Nostr VPN and Logseq posted routine builds. Bitcoin added two wallet updates. Self-hosting contributed one Nextcloud Android RC. No clustering within beats, no security advisories, no Lightning. Operators running llamafile, llama.cpp, or Transformers have patches waiting.

Private KI statt Datenkrake: Lumo, Maple & Co. im Vergleich – wie vertraulich sind KI-Chats wirklich?
ChatGPT, Claude und Gemini lesen mit – per Gerichtsbeschluss sogar gelöschte Chats. Wir vergleichen die privaten Alternativen Lumo, Maple AI, Duck.ai und Venice, erklären ehrlich, was „Ende-zu-Ende-Verschlüsselung“ bei KI wirklich bedeutet, und klären, ob eine davon mit Claude Opus mithalten kann.

A slow day across beats. Self-hosting delivered the only security work: BorgBackup 1.4.5 patches a low-severity issue alongside feature additions. Privacy logged two client updates, Trilium notes and Yattee video. AI contributed two llama.cpp commits within the same build window. No protocol changes, no Lightning, no Bitcoin core. Operators running Borg should stage the update; the rest is maintenance.

How Do You Delete a Nostr Account? The Answer Might Surprise You 🔑
"How do I delete my Nostr account?" It's one of the first questions many people ask after trying Nostr. If you're used to Facebook, X, Instagram, or Reddit, you expect to find a Delete Account button somewhere in the settings. But on Nostr, that button doesn't exist. Not because the developers forgot to add it, but because Nostr was designed differently from the very beginning. Understanding why there is no Delete Account button also helps you understand one of Nostr's most important ideas: your identity belongs to you, not to a platform.

Two Lightning security disclosures, three quiet releases
Security day on the Lightning side. Ride The Lightning ships a dependency patch with zero production vulnerabilities. Delving Bitcoin surfaces twin memory exhaustion DoS vectors in Core Lightning. The rest of the wire is maintenance: Bitcoin Safe rebrand and BDK 3.0 bump, Radicale MIME fix, Qwen Code point release. No protocol changes, no bitcoin-core, no infrastructure alerts. Operators running RTL or CLN should read the disclosures; the remaining updates are low-urgency.

Privacy day: five releases, one tablet feature
Privacy tools dominated the wire. Five of thirteen items came from the Privacy beat, led by Signal Android adding tablet linking, Thunderbird for Android shipping an incognito keyboard setting, and maintenance releases for Anytype and NewPipe Extractor. AI projects released three library updates with minimal operational detail. Nostr saw Amber improve multi-request approval grouping and Wisp add tracking-param stripping. Bitcoin releases were routine: Cake Wallet added home-screen upgrades and Zcash updates, Liquid GDK bumped dependencies, and Fedimint Web issued a canary build. No Lightning. No protocol patches. Operators running Signal or Thunderbird on Android gain new privacy controls; the rest is dependency churn.

Two security patches, nine AI releases, quiet protocols
Security work centered on Element Android and Bitwarden Server, both addressing file-handling and data-handling issues. AI infrastructure saw nine releases, led by LangChain's reasoning-effort parameter additions for Anthropic and OpenAI integrations, Cline Desktop's first public macOS agent client, and InvokeAI's security patch. Privacy tooling contributed seven items, including Tuta timezone support and Notesnook Android and Bitwarden client updates. Bitcoin delivered three wallet releases: BlueWallet 8.0.1 with iOS 26 Liquid Glass design and BC-UR v2 air-gap support, Trezor Suite 26.7.1 with Tron staking and EVM transaction cancellation, and a Vexl patch. Nostr added Sidecar 1.5.0 on Firefox, strfry 1.1.1, and Ditto 2.32.0. No Lightning, no protocol CVEs beyond the two patches.
