Jade doesn’t use a physical secure element. We just published a full post on how the Virtual Secure Element works: https://blog.blockstream.com/jade-virtual-secure-element/ Your recovery phrase sits encrypted on the device. Unlocking it needs the PIN you type on Jade and a key share from a blind oracle. Neither is enough by itself. The oracle never sees the real PIN or any wallet data. It only gets a scrambled version that includes a secret unique to that particular Jade. Three wrong PINs and both sides wipe. Device and oracle. After that the encrypted data is permanently unusable without the recovery phrase. A locked Jade holds nothing an attacker can use alone. Everything is open source, firmware, hardware, and the oracle. You can run the oracle yourself, or skip it completely and use SeedQR or type the recovery phrase.

A passphrase adds an advanced layer of protection to the Bitcoin self-custody setup you already have, with nothing to buy. Your existing funds don't move on their own. Back up the passphrase as carefully as your recovery phrase, then send them across. https://youtube.com/shorts/XdhNn5cIEd8 Lose the passphrase and the funds are gone, even if you still hold your recovery phrase. It isn't a password you can reset, it's part of the key. Jade shows an 8 character fingerprint each session. If it doesn't match, you've typo'd. Passphrases are the BIP-39 standard, not a Jade feature, so the same one works on any wallet that supports it. Case and spaces count.

The curve behind every Bitcoin signature has a weakness to quantum computers, understood since the 1990s. The only thing missing is the machine. Quantum is the Bitcoin Security Consortium's first focus, and Jonas Nick explains why we build for that adversary now instead of betting it never arrives. https://youtube.com/shorts/tPA_e3j2Ugc?si=5Fji3bBFqO2f64gH

New research from Kyrylo Riabov and Artem Chystiakov. This Blockstream paper explores enforcing asset rules onchain with a Simplicity covenant on the . Ordinary transfers need no issuer signature, and the holder keeps their own keys. https://github.com/Arvolear/research-papers/blob/master/simplicity/DAMP.pdf

Post-quantum signatures aren't new, they've existed for about 45 years. on why OP_CHECKSHRINCS proposed by Blockstream Research 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. https://youtube.com/shorts/_oGgAEfwo-E?feature=share

Proud to be a founding member of the @BTCconsortium. Bitcoin’s long-term security has always been core to what we do, from open-source research to practical post-quantum work like OP_CHECKSHRINCS. Supporting the independent developer community that keeps the network resilient is a natural extension of that mission.

Hashcash, invented by , is cited in the Bitcoin whitepaper. Yet in 2013, watching bitcoin pass $100, he thought he had missed the boat. https://youtube.com/shorts/52_LhzOOIIQ?feature=share Own your bitcoin from day one. Download the Blockstream app: https://blockstream.com/app/

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
