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. 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

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.

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. 🔗
