What if Bitcoin needs to switch to post-quantum signatures? Our CEO and Bitcoin OG @Adam Back explains how Taproot already gives us this capability.
Living 100% on Bitcoin isn't theoretical anymore. @Julian Figueroa and @Joe Nakamoto cover the full ecosystem. Level one: a Jade hardware wallet for cold storage and the Blockstream app for instant Lightning payments. 🔒⚡️
This code implements RSA encryption—the foundation of secure communication. In the 90s governments classified it as a weapon & tried to ban its export. Bitcoin uses digital signatures, applying these same public-key cryptographic principles to secure the network. Math won. image Wear the math they couldn't ban. Support the principles that Bitcoin is built on. Limited edition RSA t-shirt available now. https://store.blockstream.com/products/rsa-t-shirt-2025-limited-edition
Fiat debt traps don't fix themselves, but Bitcoin offers an exit. @Roberto Rios (Peruvian Bull) exposes how deep the $1.7 trillion student debt crisis runs. Secure your opt-out with Blockstream Jade.

@Adam Back joined Yahoo Finance’s Market Catalysts this morning to break down: 🔹 Why Bitcoin’s 2025 price action looks “lackluster” on the surface 🔹 Why Bitcoin treasury companies are becoming a compelling investment theme 🔹 How today’s landscape compares to when he first got involved in 2013 A great overview of where Bitcoin stands heading into 2026.

In the 1990s, governments tried to ban strong encryption. Cypherpunks printed RSA code on t-shirts to prove a point: you can't stop math. Three decades later, Bitcoin proves they were right: you can't stop math. You can't ban freedom. image When @Adam Back printed the original RSA code t-shirt in 1995, he showed that mathematical truth can't be banned. Today's limited edition version carries that spirit forward. Wear the code that challenged authority just by existing. https://store.blockstream.com/products/rsa-t-shirt-2025-limited-edition
