We urge all Core Lightning users running experimental features to disable them immediately while we investigate.

LIQUID NETWORK UPDATE: TRANSACTIONS RESUMED, PEG-OUTS DISABLED
Status as of September 10, 2026, 19:55 UTC
Recovery Status
The Liquid Network has entered into its next recovery phase. Block production has resumed, and functionary nodes are signing and validating blocks. Transactions on the network have resumed, while peg-outs remain disabled as a precautionary measure while the final stage of recovery continues.
Rigorous testing, AI-assisted code scanning, and continuous network monitoring are underway by internal and external teams. Further information on the resumption of peg-outs will be shared once available.
Important: What You Should Know
Users do not need to take any proactive steps at this time. If you operate a Liquid node, please update to Elements v23.3.4 immediately.
Reminder: Beware of Scams
There are reports of scammers attempting to exploit the situation through fraudulent update sites and messages. Please rely only on official Liquid Network, Blockstream Jade, and Blockstream channels. Never send funds to unfamiliar addresses, transfer assets to unknown channels, or disclose private keys or seed phrases in response to unsolicited communications.
More Updates Soon
Updates will be shared through official Liquid Network and Blockstream channels. The Liquid Federation and Blockstream again sincerely thank the broader Bitcoin community for its continued assistance and support during this recovery.
LIQUID NETWORK UPDATE: OPERATIONS RESUMED, RECOVERY ONGOING
Status as of September 10, 2026, 10:00 UTC
Recovery Status
The Liquid Network has entered the next phase of its controlled resumption. As a precautionary measure, block production has resumed without transactions while the network is monitored to confirm full stabilization.
Blockstream confirms that the required functionary and bridge node updates have been successfully deployed. Functionary nodes are signing and validating blocks as intended.
Peg operations, including PAK-authorized peg-outs, remain suspended while work continues on the final recovery stage: restoring the BTC/LBTC reserve is in progress.
Reminder: Beware of Scams

Thank You
The Liquid Federation and Blockstream sincerely thank the broader Bitcoin community and security teams for their assistance and continued support during this challenging time.
Safely restoring full operations remains the highest priority.

LIQUID NETWORK UPDATE: NEW RELEASE
Status as of September 9, 2026, 13:30 UTC
Update to Elements v23.3.4
The emergency Elements v23.3.4 release is now available. Functionary nodes are being updated immediately and we recommend all Liquid node runners do the same. This release addresses the proof-verification cache vulnerability, hardening the cache keys used for range proofs.
Elements v23.3.4 has undergone multiple rounds of internal and external review, including by the Bitcoin Red Team, Alpen Labs and others. Blockstream sincerely thanks these teams for their valuable review and collaboration.
Liquid Network Recovery Plan
The recovery plan remains under active development and may be revised as testing and validation continue. Based on current assessments, the anticipated stages are:
1) Resume block production while peg operations remain suspended.
2) Replay transactions verified as valid.
3) Resume peg operations once the network state has been fully restored including a return of funds.
Blockstream is testing the procedures for the first two stages in parallel. While the current plan anticipates proceeding in the order above, the sequencing and implementation may be adjusted based on the results. No stage will proceed until it is considered safe to advance.
Beware of Scams
There are reports of scammers attempting to exploit this situation by misleading users with fake update sites. This is a reminder to only rely on official Liquid Network and Blockstream channels, and never send funds or disclose private keys or seed phrases in response to unsolicited messages.
We again thank the broader Bitcoin community and our research collaborators for their continued support and assistance. Safely restoring normal operations remains the highest priority for the Liquid Federation and Blockstream.

Re today's Liquid incident: the ~4,000 BTC peg-out went through SideSwap's peg-out service on a customer order. As @Liquid_BTC confirmed, our PAK was not compromised. The L-BTC came from an Elements bug, not from any SideSwap system. Peg-in/out paused while Liquid is. Updates here.
We are aware of a security incident on @Liquid_BTC. Purported white-hat hackers have withdrawn ~4,000 BTC (~$320 million) from the Liquid Federation wallet. The @Blockstream team is working on contacting them on-chain with a signed message.
What we know so far is that the funds were withdrawn via the SideSwap PAK (Peg-out Authorization Key), but that key was not compromised, nor were any others.
Exchanges have been notified and have already paused (or will pause) LBTC deposits and withdrawals. Other Liquid assets such as USDT, DePix, and RWAs are unaffected by this security incident.
Bridge nodes have been temporarily disabled, so no new transactions can be submitted to the network. Effectively, the Liquid sidechain is paused until this issue is resolved.
Liquid wallets will be impacted, and we're sorry for any inconvenience. Federation members are actively working on resolving this so we can restore normal network activity.

Owning your money outright is a financial edge that's hard to take away.

Liquid has reached its 4 millionth block. 🎉
Born from the OG sidechain whitepaper in 2014, developed and announced alongside the first sidechain, Elements Alpha, in 2015, and launched in production in 2018, Liquid has quietly become an important piece of infrastructure for bitcoin over the years.
It enables confidentiality by default, native asset issuance, 0-conf, and, more recently, high-assurance Simplicity smart contracts and a growing DeFi ecosystem.
Today, Liquid supports more than $5B in tokenized real-world assets, spanning stablecoins like USDT and DEPIX, tokenized stocks, private credit, and gold funds.
Four million blocks down. Bitcoin’s financial layer is just getting started.

In-app swaps in the Blockstream app are temporarily unavailable due to a service interruption with our swap partner @Boltzhq.
Only the swaps are affected. @Liquid_BTC is unaffected, and your funds remain fully secure under your control. Send, receive, and all other core features continue to work normally.
We’ll share updates as soon as swaps are restored.

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.

“What Satoshi solved is the difficulty adjustment. Dynamic difficulty in the mining so that it reacts to the market. Letting the market set the price but fixing the rate of supply and the total supply. The now-famous 21 million limit. Those were Satoshi's additions."
