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. 🇯🇵

Pay a Lightning invoice...from cold storage. Your Jade holds LBTC. The Blockstream app handles the swap to Lightning. You sign the transaction offline on your Jade. The invoice gets paid. Forget hot wallet security holes. Get all the speed and all the security with Jade. https://youtube.com/shorts/_w4hgpCdr4M Download the Blockstream app: https://blockstream.com/app/ Secure your bitcoin with Jade: https://store.blockstream.com/products/jade-plus

Is your Bitcoin really safe on the exchange? Take self-custody with Jade Plus: open-source, Bitcoin and native. 12-word recovery phrase → Genuine Check → verify addresses on-device. Withdraw Bitcoin and USDt directly to cold storage. https://youtube.com/shorts/5fOhkHbZz_8

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.

New post-quantum signature scheme from Blockstream Research: SHRIMPS brings 2.5 KB hash-based signatures across multiple devices. h/t Jonas Nick, Mikhail Kudinov, Oleksandr Kurbatov https://delvingbitcoin.org/t/shrimps-2-5-kb-post-quantum-signatures-across-multiple-stateful-devices/2355

Every post-quantum upgrade for Bitcoin brings significant trade-offs: larger signatures, slower verification, new assumptions, statefulness. Blockstream Research led by Jonas Nick is pioneering the research and implementation space to inform potential upgrade paths. https://youtube.com/shorts/rLuT4AA8daA Hash-based signatures offer a promising post-quantum alternative for Bitcoin. Jonas Nick and Mikhail Kudinov at Blockstream Research explore parameter optimization specifically for Bitcoin's requirements. https://eprint.iacr.org/2025/2203.pdf

Real transactions. Real production sidechain. Blockstream Research is running SHRINCS, an optimized hash-based signature scheme, on the 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. https://blog.blockstream.com/blockstream-jade-now-supported-by-unchained/

How does Jade work with Lightning if it's a hardware wallet? The 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.

“With Bitcoin you have an early stage adoption story so it's effectively like buying internet companies stocks in like the early 90s.“ - Blockstream CEO https://youtube.com/shorts/cXATaj0YJeQ Bitcoin is early-stage adoption. Hold it on your phone with the Blockstream app: http://blockstream.com/app

All the speed. All the security. Blockstream app v5.2.0 lets you seamlessly swap across all three layers of bitcoin, all while being protected by Blockstream Jade: ⚡ Receive Lightning payments directly into cold storage ⚡ Pay Lightning invoices from cold storage 🔄 Swap seamlessly between Lightning, , and on-chain Convenience and control, all within the Blockstream app. https://youtube.com/shorts/ABvcLlv457k?feature=share Lightning ↔ Liquid swaps arrived in December. On-chain ↔ Liquid swaps land today. With this update, Blockstream Jade is the first hardware wallet with full access to the Bitcoin stack: ⚡ Lightning for speed 🌊 Liquid for flexibility ⛓️ On-chain for finality https://blog.blockstream.com/jade-lightning-payments-are-here/ Download the Blockstream app https://blockstream.com/app/ Secure your bitcoin with Jade https://store.blockstream.com/products/jade-plus

Congratulations to the Blockstream Research team. A well-earned acceptance. https://x.com/blksresearch/status/2031667618298605930

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 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/

Happy Monday everyone!
