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

SHRIMPS: 2.5 KB post-quantum signatures across multiple stateful devices

Abstract: SHRINCS achieves very small hash-based signatures using a stateful signer while still allowing for static backups. However, its efficient...

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.

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. 🇯🇵

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:
