“You can look at Bitcoin as is one of these multi-Millennia inventions so the discovery of a better monetary technology than gold itself and the reason for that is it is mathematically scarce.” - Blockstream CEO @Adam Back Gold supply reacts to price. Bitcoin supply is mathematically fixed. Download the Blockstream app today and hold the most scarce monetary asset in history on your phone. http://blockstream.com/app

They tried to ban this code by calling it a munition. Now it secures bank accounts, messages, and laid the cryptographic foundation for the Bitcoin network. Turns out you can't stop math by writing laws about it. The shirt back displays shortened RSA encryption code in Perl. Under 1990s export laws, this made it classified munitions. The kind of thing authorities preferred you didn't wear so @Adam Back printed it on a tshirt. Live on the Blockstream Store. https://store.blockstream.com/products/rsa-t-shirt-2025-limited-edition

Is your Bitcoin really safe on the exchange? Take self-custody with Jade Plus: open-source, Bitcoin and @Liquid Network native. 12-word recovery phrase → Genuine Check → verify addresses on-device. Withdraw Bitcoin and USDt directly to cold storage.

Our CEO @Adam Back sat down with Blockchain North to discuss Bitcoin cycles, institutional adoption, and why this phase could play out differently.

Real transactions. Real production sidechain. Blockstream Research is running SHRINCS, an optimized hash-based signature scheme, on the @Liquid Network right now. This is what preparing Bitcoin infrastructure for the post-quantum era looks like.

When the headlines get hysterical, it's historically been the best time to buy Bitcoin. @Julian Figueroa has 10 years of receipts to prove it in the latest Exit Manual. Keep your stack in cold storage bull or bear with Jade.

How Blockstream Jade works with Unchained: You hold two keys. Unchained holds one recovery key. To spend, two signatures are required. You stay in control. Unchained is your safety net.

The Blockstream Jade is the first Bitcoin hardware wallet to interact with Lightning. Exchange → Lightning → @Liquid Network → mainchain cold storage. All signed offline with Jade. Your keys never touch an internet-connected device.

The Blockstream Research team is developing and deploying post-quantum security for Bitcoin. Director of Research Jonas Nick joined the @TFTC pod to talk about making sure Bitcoin stays resilient to the most powerful adversaries and what that effort would mean. Simplicity is already live on the @Liquid Network and able to quantum secure LBTC and Liquid assets. Get hands-on with the high assurance smart contract scripting language in the Simplicity Office Hours every Tuesday 8am PT. Ask questions, share ideas, see what developers are building.

A typed, combinator-based, smart contract language for Bitcoin-like blockchains.

Our CMO Peter Bain discusses quantum computing and its implications for cryptography on FINTECH TV Global, a longer-term challenge the industry is actively preparing for, with Blockstream Research leading the way.

How does Jade work with Lightning if it's a hardware wallet? The @Liquid Network is the bridge. When someone sends a Lightning payment to your Blockstream app wallet, it arrives as LBTC in your Jade-secured wallet. When you pay a Lightning invoice, your LBTC swaps out over Lightning. Addresses are generated offline. Jade signs every transaction. Private keys never touch an internet-connected device. See exactly how much you could keep in your DCA stack by utilizing Lightning to Liquid swaps. Check out Blockstream's new UTXO fee calculator. 🔗

Weekly DCA: buy bitcoin on an exchange, withdraw over Lightning to the Blockstream app. It lands as LBTC in your Blockstream Jade wallet instantly. Once a month, when on-chain fees dip, sweep everything to mainchain bitcoin. Minimize fees, maximize security. Download the Blockstream app:
