Since mid-2024, Blockstream Services USA and Blockstream Services Canada have not been under the ownership, control, or management of Blockstream Corp. The businesses were spun out as part of the Blockstream Mining business and have since operated as separate companies, with no shared equity ownership or management with Blockstream Corp. Following the separation, they retained the Blockstream name for a limited period under a brand licensing agreement.

We have published the technical security assessment of the September 6 Liquid incident, which details the root cause and mechanics of the exploit, an incident timeline, and the engineering and security changes being implemented in response. blog.blockstream.com/liquid-…

To those responsible for the theft of bitcoin from the Liquid Network: Blockstream will not pay a ransom for the return of stolen funds. Taking assets without authorization and withholding their return is a crime, not responsible disclosure. It is not white-hat activity. It is theft. We have engaged in good faith in an effort to secure the return of stolen user funds and protect the broader Bitcoin community. That effort should not be mistaken for acceptance of the actions taken nor of the terms being demanded. We will not be a party to the precedent that open-source software developed for the good of the Bitcoin community should subject its developers to paying a ransom that far exceeds their economic participation. Bitcoin is hard money and can’t be minted without costs, Bitcoin doesn’t haircut users to pay a ransom. To the Bitcoin community: We are fighting for what we believe in, for the users whose funds were taken, and for the principles on which Bitcoin was built. The community has demonstrated incredible resolve with teams of people dedicating their time in support of each other to identify and patch vulnerabilities in each other's products and systems. We are all driven by the mission that Bitcoin is the single best asset, for every person, company, and institution on the planet to invest, use, and build on. The world is a different place with the advancements of AI, and the Bitcoin community has responded with force to combat that threat. Damage has been done, battles have been lost, but on the whole the Bitcoin community is gaining ground in the war with bad actors. We want to thank the community for those efforts, for your support in hardening the network, helping users recover funds, and for your support in our assertion that crime does not deserve rewards. To those holding the stolen bitcoin: There is still an opportunity to resolve this responsibly. The bitcoin can be returned and we can revert to the standard of white-hat principals. However, if the funds are not returned, we will pursue every lawful avenue available to us. We will work with law enforcement, exchanges, service providers, forensic specialists, and other relevant parties to trace and recover the assets and identify those responsible. More importantly, Bitcoin is transparent by design and the community is made up of the most sophisticated engineers, cryptographers, and white-hat hackers globally. Transactions do not disappear, and neither does the evidence they leave behind. We will not pay for the return of stolen property. We will not abandon our users. The Bitcoin community will not stop pursuing the funds. Return the bitcoin.

Security Notice & Phishing Alert Following the recent Liquid Network incident, scammers are impersonating Liquid and Blockstream and urging users to "take action." Don't.

Never - Send funds to a "recovery" address Never - Enter your seed on a "migration" site Never - Install firmware or software from an email link Never - Reply to unsolicited DMs Treat as scams: "mandatory security update" emails and portals, refund / re-peg / "claim L-BTC" sites, fake support DMs, lookalike domains, and unsolicited "white-hat" or bounty outreach.

Following the recent incident affecting the Liquid Network and the movement of funds, Blockstream, as Liquid’s technical provider, and the Liquid Federation have been working diligently to resolve the ongoing situation and ensure the return of assets. Updated software has been deployed as the Federation members prepare the network for a coordinated restart. Our teams remain focused on further hardening the network. We want to thank the broader Bitcoin community for their patience, support, advice, and assistance throughout this process. We will continue to provide updates as progress is made.

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.

OP_CHECKSHRINCS in full, from @blksresearch: blog.blockstream.com/op_chec…

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.

If Bitcoin had to choose a lattice signature today, it would be Falcon-1024. @blksresearch has published a full report on Dilithium, Falcon and Hawk: what each costs on-chain, how hard each is to implement safely, and which assumptions you are trusting. blog.blockstream.com/lattice…

When sellers run out, price moves. Don't FOMO back in later. Stack now directly to self-custody. blockstream.com/app/

“The amount of Bitcoin buying is much higher than Bitcoin being mined So it's just a question of when the sellers run out of Bitcoin to sell or decide they don't want to sell any more.” Blockstream CEO @adam3us
