Managing a Lightning node used to mean living in the command line. The Core Lightning app puts your channels, fees, and peer control in one screen. Your node, your rules. Core Lightning runs at home in one click on @Umbrel ☂️ or @Start9. Run the app from source:

Everyone you've orange-pilled is still leaving their coins on an exchange. The best way to teach self-custody is to hand someone the keys. Jade Core makes it a five-minute conversation, not a lecture. Bring someone in this week. https://store.blockstream.com/products/blockstream-jade-core

Hashcash, invented by @npub1qg8j...24kw, is cited in the Bitcoin whitepaper. Yet in 2013, watching bitcoin pass $100, he thought he had missed the boat. Own your bitcoin from day one. Download the Blockstream app:

Self-custody got a reputation for being hard. Jade Core is here to end it. Serious protection for your bitcoin, with a setup simple enough that "I'll do it later" stops being a reason. https://store.blockstream.com/products/blockstream-jade-core

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. The fallback needs no state, so a lost device is never a lost wallet. More expensive to spend from, but always accessible. Blockstream Research Director Jonas Nick on building a post-quantum scheme that stays safe even when hardware fails:

OP_CHECKSHRINCS: A Hash-Based Signature Opcode for Post-Quantum Bitcoin

OP_CHECKSHRINCS is a proposed Bitcoin opcode for post-quantum signatures whose security rests on SHA-256, the hash function Bitcoin already uses.

Getting off an exchange shouldn't be hard. Jade Core is the simplest way to hold your own bitcoin, built for anyone taking self-custody for the first time. @npub1qg8j...24kw on the thinking behind it.

Satoshi chose secp256k1 for Bitcoin’s cryptography. Jonas Nick and Blockstream Research are among the co-maintainers of libsecp256k1, the library every Bitcoin node runs to implement it. Researching what comes next is a natural extension of that work.

The Blockstream Explorer API is home to one of the fastest ways to sync a Bitcoin wallet. With QuickSync, you send one descriptor and get the complete history back in a single response. Grab an API key and see it for yourself. 🔗

Q2 was Blockstream moving from research to release. Blockstream Research took post-quantum Bitcoin from a live deployment on the @Liquid Network to OP_CHECKSHRINCS, a signature opcode the whole network can evaluate. Blockstream Jade became a three-model lineup, with the new Jade Core turning self-custody into a five-minute move off an exchange. Liquid published a roadmap that puts 0-conf and a trust-minimized bridge on the calendar. Core Lightning strengthened node architecture with bwatch, while the Explorer API kept blockchain data fast and dependable at enterprise scale. Blockstream's Q2 2026 Quarterly Update is live.

Blockstream Quarterly Update - Q2 2026

From a proposed post-quantum opcode to a reimagined Jade lineup and a Liquid roadmap with dates, here's what Blockstream shipped in Q2 2026.

Bitcoin started as a discovery, not an invention. @npub1qg8j...24kw explains why on Bitcoin Suisse AG, plus the post-quantum migration and how Blockstream Research is preparing Bitcoin for it with OP_CHECKSHRINCS.

Under 1 million addresses hold a whole bitcoin. There are about 59 million millionaires. The math does not allow one each. Every sat counts when there aren't enough whole coins to go around. Buy and self-custody in the Blockstream app

The world is already migrating to post-quantum schemes. SSH clients warn when a server can't negotiate one. Browsers are defaulting to post-quantum TLS where available. Jonas Nick of Blockstream Research on why a quantum threat to banking is no reason to leave Bitcoin unsecured.

"Ultimately people can only sell once and the number of coins left on exchange is diminishing." - Adam Back on Bitcoin supply dynamics. Coins on exchanges are diminishing. The ones who move first stack the most.

Blockstream Local came to Pontarlier BTC in France for an evening on Bitcoin basics. Attendees walked away with bitcoin self-custody knowledge and Blockstream Jade, hardware wallets to put theory into practice. Register your meetup with Blockstream Local to get educational resources and hardware wallets to support your community.
