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.

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. 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. 🔗 https://blockstream.com/app/utxo-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 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/
