Why isn't the #Bitcoin mailing list on #nostr yet?! 📨 It’s the perfect public, decentralized solution - and could be a catalyst for new development. @BLUESKY and @Rijndael lay out the opportunity in BR095.

Plugins are coming to Electrum! 👀👀

Plugins are coming to Electrum: ✅ NIP47 support: Remote control Electrum’s Lightning wallet over Nostr ✅ Budgets & expiry dates for safe client connections ✅ Third-party user-space plugin architecture @BLUESKY and @Rijndael break down the risks and rewards in BR095.

Is the lack of dark market adoption a failure of Lightning, or simply a signal that cheap and fast payments (not privacy) is the primary need? @BLUESKY and @Rijndael discuss dark markets and LN privacy challenges in BR095.

Humans love round numbers - and #bitcoin transactions reflect it. UTXOracle analyzes rounded dollar transaction amounts to calculate the bitcoin price. (Written as a single Python file!) @Simple Steve's clever design is discussed by @BLUESKY , @Rob Hamilton & @Rijndael in BR095.

BIG COLDCARD update 🚀 ✅ Multisig TX finalization & PushTX ✅ Signed multisig export files ✅ NFC export retries ✅ CCC: policy enclave, daily limits, whitelists, web 2FA ✅ Key Teleport ✅ Delta PIN wipes @BLUESKY shares the new features with @Rob Hamilton & @Rijndael in BR095.

#nostr brings a social graph to #bitcoin. ⚡ (Now discontinued) Mutiny Wallet was one of the first to use nostr to connect payments & people. 👥 Cashu & @Fountain continue to demonstrate the power of the nostr social graph. @BLUESKY , @hodlbod , @jb55 & @miljan discuss in BR078.

Zaps are going mainstream. ⚡️ @miljan explains how @primal built a Strike-powered custodial Lightning wallet, allowing anyone to zap on #nostr in just a few clicks. [BR083]

The VC model rewards sitting on inventions. #Nostr flips that and creates a compounding innovation loop - what you build benefits everyone (not just you). @BLUESKY and @calle break it down in BR083.

What if your COLDCARD could manage UTXO state updates without ever going online? 🔐 @Rob Hamilton , @BLUESKY & @Paul explore how snapshotting UTXO state and secure serialization can enable vault-like behavior - offline, fully air-gapped, and even across borders. [BR094]

Want to share a seed or SSH key securely across borders? Meet Key Teleport: a new protocol by @Coinkite to transfer secrets without trusting phones, computers, or comms. All via QR, NFC, and BBQr. @BLUESKY & @Rob Hamilton discuss the new protocol and its applications in BR094.

@BLUESKY is calling for better accounting software for #bitcoin companies! Accountancy for a Bitcoin business means rethinking: – Spending privacy – Invoicing without doxxing – Tax-aware coin control. Are you building it? Get in touch! [BR094]

Harbor RC2 is almost here! 🚀 Fedimint and Cashu with multi-mint support ✅ Rust-based ✅ Desktop-first ✅ No JavaScript! ✅ @Paul discusses the current state of development with @BLUESKY & @Rob Hamilton in BR094.

We love Zaprite! And the Bitcoin Review gang is also rooting for it evolve... A desktop app? More local APIs? Integration with tools like Sparrow& @ZEUS ? BIP329 labels? Just some of the ideas floating around in @BLUESKY's feature request corner in BR094.

Could OMEMO be a solution to #nostr DM privacy? ✅ Forward secrecy ✅ Offline messages ✅ Ephemeral sessions @BLUESKY , @Paul , and @Rob Hamilton dig into nostr secure comms in BR094.

Screenshots to code! 📸 Front end dev @Paul shares his vibe coding workflow using Figma combined with AI tools. But with AI bridging Figma's limitations, could it soon be rendered obsolete? [BR094]

Is vibe coding creating knowledge debt? @Paul , @Rob Hamilton and @BLUESKY warn of AI-generated code that's hard to maintain and lacking a high level *human* understanding. Do we have something to learn from the military approach to software development? [BR094]

Privacy wallets on #Bitcoin have taken a hit in recent years, and UX often still trails traditional banking. @BLUESKY , @Paul and @Rob Hamilton discuss the evolving Bitcoin ecosystem, and some potential solutions on the horizon, in BR094.

Privacy for businesses shouldn’t be a bolt-on - it should be default. Joinmarket’s peer-to-peer coinjoin offers a rare escape, but few businesses use it. @BLUESKY , @Paul and @Rob Hamilton discuss the potential for embedded privacy (that doesn't break accounting) in BR094.
