マルチシグを、もっとシンプルに。@BlockstreamApp なら、数タップでビットコインに2つ目の鍵を追加できます。追加の設定は不要で、完全なセルフカストディのままです。 https://t.co/G4GJhqg6In

Multisig, minus the complexity. The @BlockstreamApp is the easy way to get started: add a second key to your bitcoin in a few taps, with nothing extra to set up and full self-custody.

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 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.

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。

2 months ago

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. You can monitor the situation via @mempool's https://t.co/M46Zhn8nlY site below: https://t.co/B8j9u4j6i4

SideSwap

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。

Owning your money outright is a financial edge that's hard to take away. @kinetic_finance lays it out in Exit Manual Episode #45, and the Blockstream app makes it real.

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.
