2% allocation. If Bitcoin doesn't perform, the portfolio recovers. If it continues toward $200T, the effect is outsized. @adam3us on why pension funds don't need to form an opinion on how far Bitcoin goes, just stay the course and don't rebalance.

Quantum-ready Bitcoin in practice: To get ready, you send to a new Taproot address. With OP_CHECKSHRINCS by @blksresearch, it holds a Schnorr key and a post-quantum key. You keep spending with Schnorr at today's cost. When a quantum computer arrives, you spend with the post-quantum key.

Sync an entire Bitcoin wallet in seconds. QuickSync is a new open-source wallet scanning protocol by Blockstream that turns hundreds of address lookups into one descriptor request, dramatically cutting sync time when using the Blockstream Explorer API.

Self-custody does not have to wait for shipping. Create a wallet in the Blockstream app, write your recovery phrase on paper, set a PIN, and you can start to receive bitcoin securely. Fully open source and reviewed in the open, from a team building on Bitcoin since 2014.

Buy bitcoin on an exchange and it sits as a balance on their books. Until you withdraw, it is not bitcoin you hold. In the Blockstream app, every purchase lands in a wallet you control, in self-custody from the first second.

Post-quantum signatures aren't new, they've existed for about 45 years. @adam3us on why OP_CHECKSHRINCS proposed by @blksresearch is designed as a minimal, provable change to Bitcoin, and why starting the migration now means more real-world data before it's actually needed.

Today, the best quantum hardware can just about factor 21 (3 x 7). @blksresearch hired @kudinov_mikhail, one of the cryptographers behind NIST's post-quantum signature standard, and we have already proposed OP_CHECKSHRINCS, an optimized hash-based signature opcode for Bitcoin.

Reusing a bitcoin address links your transactions and weakens your privacy. The Blockstream app gives you a fresh receive address every time, and your funds stay in self-custody from the moment you buy.

OP_CHECKSHRINCS uses one public key with two ways to spend. The first path keeps signatures small by having the device track how many times it has signed. The second path doesn't track anything and is always available as a safety net. If your device is lost or replaced, you restore with your recovery phrase and fall back to that second path. It's more expensive to spend from, but you are never locked out. This is how SHRINCS works.

Today, losing your hardware wallet is fine. Your recovery phrase gets you back in. In a post-quantum signing setup, the device also holds state: a running count of how many times it has signed. That state matters for security. SHRINCS is designed so that if the device is lost, the recovery phrase loads into a new one and falls back to a path that needs no state at all.

After 7 years, Blockstream Research Director @n1ckler is stepping back as a libsecp256k1 maintainer, leaving the library in the strong hands of its other long-time maintainers. @blksresearch remains a key contributor. Learn more about this cryptographic library that secures every Bitcoin and @Liquid_BTC transaction. ⬇️
libsecp256k1 is the cryptographic library that secures every Bitcoin transaction and @blksresearch is one of its key contributors and maintainers. They also maintain libsecp256k1-zkp, the extended fork that powers @Liquid_BTC's Confidential Transactions, MuSig2, and zero-knowledge proofs. The team has just brought the zkp fork up to date with 2.5 years of upstream improvements.

Bitcoin’s 200-week moving average just hit $62K, making current levels an attractive entry point for capital. In a recent interview, Blockstream CEO @adam3us broke down why the current market dip is a value trade driven by institutional focus, falling exchange supply, and rising Bitcoin dominance. As tourists rotate into other sectors, smart money is building a lower cost basis. Watch the full breakdown below.

A post-quantum upgrade to Bitcoin that collapses network throughput is not a real upgrade. SHRINCS sits well above the existing standard candidates on the throughput scale, without relying on newer and less proven cryptographic assumptions.
