"Bitcoin is more a discovery than an invention. People had the rough idea of how a decentralized electronic cash could work. Satoshi figured out the rest.” - Blockstream CEO @Adam Back on Fox Business with Liz Claman

The results are in from the Blockstream Turin Simplicity Hackathon. 20 developers spent a weekend building real smart contracts on Simplicity covenant DEXs, inheritance tools, post-quantum wallets, and more. First place goes to: PQ Liquid Wallet, taking home $3,000 in bitcoin: PQ Liquid Wallet is the first wallet to test Blockstream's research on protecting Bitcoin from future quantum computers. Second and third place each take home a Blockstream Jade for every team member. Full breakdown of all six submissions on the blog.

Stefan Keller, Blockstream's Director of Delivery, takes the Main Stage at The Crypto Valley Conference on May 28 on building the new Swiss banking infrastructure. If you're running or evaluating institutional Bitcoin operations across custody, tokenization, and settlement, this is the session to be in the room for.

From self-custody to institutional settlement, Blockstream builds on Bitcoin without compromising on security. Our CMO Peter Bain joined The Block to share how that shapes everything we build.

Optimized stateful hash-based signatures can offer better trade-offs than the standard schemes available today. SHRINCS is live on the @Liquid Network in production today via Simplicity. Jonas Nick at OPNEXT on why this may allow Bitcoin to operate in a post-quantum world without betting on specific future software. Full technical writeup: https://blog.blockstream.com/op_checkshrincs-a-hash-based-signature-opcode-for-post-quantum-bitcoin/

There is no concrete post-quantum signature scheme for Bitcoin today. But over the last year Blockstream Research has been working on exactly this. Director Jonas Nick lays out the proposal: OP_CHECKSHRINCS, a hash-based signature opcode for post-quantum Bitcoin. SHRINCS reaches up to 3 TPS on the compact path. 580-byte signatures from a dedicated signing device. A stateless fallback always available. Already demonstrated on the @Liquid Network . The C++ implementation, Simplicity verifier, and draft spec are all on GitHub. https://blog.blockstream.com/op_checkshrincs-a-hash-based-signature-opcode-for-post-quantum-bitcoin/

The next bull run isn't waiting for you to get your self-custody sorted. In the latest Exit Manual, @Julian Figueroa brings a message from the future explaining where we are in the cycle and why you'll need a Jade in your hands.
