Blockstream

Today in Lugano with STOKR and Fulgur Ventures we’re hosting Bitcoin’s brightest minds for the Bitcoin Capital Summit. Where capital meets cryptography and balance sheets turn Bitcoin-native. ⚡

Bitcoin adoption keeps growing. Each wave brings new users and new expectations. We just shipped a new release of the Blockstream app, focused on advanced user flows. Making air-gapped hardware wallet custody and 2FA-enhanced security smoother while keeping everything fast, focused, and open source. 🧵⬇️ https://blossom.primal.net/f71127162a3f35b7cfbc73512f1b6b113322075abec56e4eba3a0c1cd3f4d2fd.mp4 Partially Signed Bitcoin Transactions (PSBTs) are what power air-gapped self-custody. Now fully supported for watch-only BTC wallets compose a transaction on your mobile, export it using native iOS or Android tools, sign it offline with your Jade, then bring it back to broadcast. Also compatible with Bitcoin Core and Sparrow Wallet. Two-factor authentication in Bitcoin multi-signature setups is a powerful, modern security method that Blockstream pioneered years ago. In this release, 2FA (on Android) is faster to configure, easier to recover, and more clearly organized improving security while removing friction for everyday use. Better UX is key to our mission of making the Blockstream app the complete Bitcoin platform. This release offers a cleaner, more intuitive UI for more advanced flows like watch-only wallets.
