Security Advisory: We are investigating reports of a potential issue affecting experimental features in Core Lightning that may impact user funds.
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

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.

本日Liquid上で起きたセキュリティインシデントについては、具体的な原因などが発覚次第また追加で共有します。
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.

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.

7/7 【まとめ】
HWウォレット利用者のうち、マルチシグを活用しているのは推定1%（約5万人規模）程度と推定。
単一障害点を避けるマルチベンダー構成において、他社端末とはアーキテクチャが異なるJade（Blind Oracle / Anti-exfil等）をクオーラムに組み込む実用的なメリットは大きいです。
6/7 【Liquid活用によるUTXO管理】
Liquid / L-USDTのコールド保管に対応する貴重な選択肢。
「取引所からLN出金 ➔ 手数料の安いLiquidで受取・積立 ➔ まとまったらメインチェーンへスワップ」という運用で、UTXOの断片化と将来の送金手数料を大幅に抑えられます。
5/7 【Anti-exfilとマルチシグ防御】
署名時のノンス操作攻撃（Chosen Nonce / Dark Skippy等）による秘密鍵漏洩を防ぐ「Anti-exfil」に対応。
また、Jade内にディスクリプタを登録できるため、お釣りアドレスすり替え攻撃の防止や、マルチシグ情報のバックアップとしても機能します。
4/7 【Blind Oracle】
Jadeは秘密鍵を端末内にそのまま保持せず暗号化して管理します。
復号鍵は「PIN＋Oracleサーバーのシークレット」で生成（PINはサーバーに送信しない）。 サーバー停止時もSeedQR等で直接復元でき、端末をステートレスに使ったマルチシグ切り替え署名にも適しています。
3/7 【エントロピー生成の柔軟性】シード生成は内部RNGだけでなく、室温やカメラノイズ、入力タイミングをアキュムレータ方式で集約。
さらにサイコロ（6面/16面等）やトランプ、コインを使った完全オフライン生成にも対応。Jadeを「最終単語のチェックサム計算だけ」に使う運用も可能です。
2/7 【進化するJadeのラインナップ】ユーザー層に合わせたラインナップ展開が進んでいます。
・Jade Classic：低価格なエントリーモデル
・Jade Plus：メタル筐体、大画面・高解像度カメラでQR運用を強化（SD更新対応）
・Jade Core（$99）：カメラを省き、スマホとのBLE連携に特化した入門機

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.
Boltzの停止を受け、LiquidとLightning間のスワップをするAqua Walletなどのサービスに影響が出ています。
Blockstreamではこの状況の早急な解決を目指し、以前から取り組んでいたBlockstream Swapを正式に公開しました。
詳細は以下の記事を確認ください。

Boltzが一時的にサービス停止になったことで、ライトニングとLiquid間のスワップも停止し、Aqua WalletなどのLiquid対応ウォレットにも影響が出ています。
Blockstreamではこの事態に対応するため、以前から準備をしていた「Blockstream Swap」の開発を優先し、近く公開する予定です。
First and foremost, we wish the @Boltzhq team the very best as they work through this situation.
They are excellent partners to Blockstream and the Bitcoin ecosystem, particularly at the intersection of layer-2 networks like Lightning and Liquid.
To strengthen ecosystem resilience and redundancy, Blockstream is launching a new swaps feature. This initiative was already in development as part of our broader effort to build a more resilient suite of tools for the Lightning and Liquid networks. This system is currently in beta testing with select participants.
This was not an effort to replace any one provider. We see Blockstream Swaps as a complementary implementation that adds much-needed redundancy and diversity to the ecosystem. These recent events have only reinforced that need, and we are accelerating efforts to bring Blockstream Swaps to market.
We welcome conversations with wallets, apps and other potential integration partners.
