You accept Lightning at your conference booth. Every payment lands as LBTC in your Jade-secured wallet on the Blockstream app. Not a hot wallet. Cold storage. Back at the hotel, you retrieve your BlockstreamJade from the safe, sign an on-chain swap, and settle the day's earnings to the Bitcoin base layer. Lightning speed in, base-layer finality out.

Heading to the Japan Bitcoin Future Forum in Yokohama this week? Get hands on with Jade, the only Bitcoin cold wallet that interacts with Lightning. See it in person with the Metaplanet team and Blockstream Japan. 🇯🇵

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.

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. https://blog.blockstream.com/blockstream-research-demonstrates-quantum-resistant-transaction-signing-on-liquid-using-simplicity-smart-contracts/

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.

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. 🔗

Users can now protect their Liquid Bitcoin and issued assets against future quantum computer attacks. Blockstream Research has deployed post-quantum signature verification on the @Liquid Network using Simplicity - a first on a production Bitcoin sidechain. Opt-in quantum protection, available today. No consensus changes required. How it works: Simplicity smart contracts enable custom spending conditions on Liquid. Lock your coins to a contract that requires post-quantum signatures to spend. There are now real transactions on Liquid mainnet using SHRINCS, our optimized hash-based signature scheme. The verifier library is open source and available now for wallet developers to integrate: https://blog.blockstream.com/blockstream-research-demonstrates-quantum-resistant-transaction-signing-on-liquid-using-simplicity-smart-contracts/
