The Liquid Federation is excited to share two recent growth milestones: the successful election of 2025 governance boards and the addition of five new member companies to the Federation, bringing total membership to 81. Together, these developments reinforce the Federation’s commitment to supporting decentralization, driving Liquid’s global reach and building Bitcoin-native capital markets.

The latest release of Elements (23.3.0) enables Liquid functionary operators to begin signaling support.
Similar to how a soft fork works in Bitcoin, Elements requires a certain threshold of acceptance over the course of an epoch. In this instance, activation requires 100% support from all functionary operators over a window of 10,080 blocks.
Today, two more functionaries began signaling for support. Keep an eye on the Simplicity tracker below and follow as it unfolds in real-time!

Dear Liquid community,
On Monday, Liquid functionaries plan to activate a Dynamic Federations (DynaFed) transition as part of ongoing HSM upgrade work.
Following the transition, Liquid’s new proof-of-reserves address will be: bc1qdlld6antmv4xug242ed83q7k4rqw50cwfns38szx4qu2f4jwaxxsuhwxxr
The team maintaining liquid.network (Mempool) has also been notified so that its proof-of-reserves display can be updated accordingly.
Most users and integrations will not need to take any action, and Liquid is expected to continue operating normally throughout the transition.
Only integrators that rely on a hardcoded fedpegscript will need to update their systems to use the current script, which is being signaled in Liquid block headers.
For those new to the Liquid community, DynaFed transitions are planned, on-chain updates to the federation’s operating parameters. They allow functionaries to rotate keys, upgrade infrastructure, or update the federation’s operator set, without disrupting network operation.
Please feel free to reach out with any questions.
LIQUID NETWORK UPDATE: INCIDENT REPORT
Status as of September 8, 2026, 19:10 UTC
What Happened?
On September 6, 2026 at 15:53:10 UTC (Liquid block 4,050,336), a vulnerability in the open-source Elements software related to how Liquid nodes cache range proof verifications was exploited, resulting in the creation of ~4,000 LBTC that were not backed by bitcoin held in reserve.
The individual(s) responsible for the exploit then used the SideSwap service, a Liquid Federation member that holds a peg-out authorization (PAK) key, to convert the unbacked LBTC to BTC via Liquid’s standard peg-out mechanism. Because the validation failure occurred at the transaction level before the peg-out was initiated, both SideSwap’s node and the Liquid Network’s globally distributed functionary nodes accepted the LBTC as valid. The functionaries processed the peg-out as authorized, releasing approximately 4,000 BTC through SideSwap’s whitelisted bitcoin address, which SideSwap then forwarded to the address specified by the exploiters. Before the incident, the Liquid reserve held approximately 4,205 BTC. Following this peg-out and additional peg-outs processed before operations were halted, the reserve balance fell to 197 BTC.
Key Clarifications
No keys were compromised. The Liquid Federation functionaries were not hacked, and no private keys were compromised. The peg-out mechanism that authorizes withdrawals to whitelisted addresses operated as designed.
Other Liquid-issued assets were not affected. USDT and other tokens issued on the Liquid Network were not impacted by the vulnerability, though they are temporarily unavailable while the network remains paused.
Investigation is ongoing. As is common in complex critical-system failure investigations, this incident arose from the convergence of several individually low-probability factors that interacted in ways that ultimately defeated the system's built-in redundancies. More detail will be shared in forthcoming communications.

LIQUID NETWORK UPDATE: NEW RELEASE
Status as of September 9, 2026, 13:10 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.
https://github.com/ElementsProject/elements/releases
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
There are reports of scammers attempting to exploit the situation through fraudulent update sites and messages. Please rely only on official Liquid Network and Blockstream channels. Never send funds or disclose private keys or seed phrases in response to unsolicited communications.
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: 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: ECOSYSTEM ACTIVITY
Status as of September 17, 2026, 21:05 UTC
Network and Ecosystem Status
Since resuming on September 10, block production and network transactions, including LBTC transfers, have operated normally. Peg-out operations remain paused while work continues with Federation members and partners toward their safe restoration. Markets and services across the ecosystem are back online.
Mifiel has resumed the issuance and transactions of its digital promissory notes, with batches confirming normally. At the exchange level, BTSE reports that its platform has re-enabled USDT-Liquid transfers and the asset is unaffected by the incident.
AQUA reports that Liquid asset transfers and peg-ins are available. Its new swap feature, Indra, is also live, enabling swaps between LBTC and Lightning BTC, although liquidity remains limited.
Other wallets are restoring core functionality as well. Bull Bitcoin and the Blockstream App report that Liquid asset transfers are available, although LBTC<>BTC and LBTC<>Lightning swap routes on those services remain unavailable until peg-outs are restored.
Meanwhile, non-LBTC swap services are returning, with SideShift re-enabling cross-chain swaps for USDT and DEPIX on Liquid.
Please note service availability varies by provider, and users should confirm deposit, withdrawal and swap availability through each provider’s official channels.
BTC Recovery and Peg-Outs
As previously reported, 3,400 BTC of the ~4,000 BTC withdrawn on September 6 has been returned to the Federation reserve. Approximately 600 BTC remains unreturned, and efforts to pursue its recovery continue.
We understand that the central question for LBTC holders is when peg-outs will resume. While we are not yet able to provide a firm date, peg-outs will resume only after full 1:1 BTC backing for LBTC has been confirmed and all required software updates, testing and independent security reviews have been completed.
The Liquid Federation memb
Blockstream’s technical security assessment of the September 6 Liquid incident is now published on the Liquid blog. It covers the exploit’s root cause and mechanics, the incident timeline, and the engineering and security changes being made in response.
The Federation continues to work closely with Blockstream and its members through the staged recovery, as well as on the security improvements and governance work following the incident. We encourage users to continue relying on official Liquid and Blockstream channels for updates. Thank you to the Liquid community for your patience and support throughout the recovery.
