Liquid restored one-to-one Bitcoin backing for LBTC two months after an exploit; Blockstream CEO Adam Back listed new cold-storage authorization keys, disabled validation caches, hardened consensus rules, and third-party audits as safeguards.
The Liquid Network said it had entered the final recovery stages after an inflation bug let attackers create unauthorized LBTC and exchange it for real Bitcoin. Blockstream said most of the stolen funds were returned through a white-hat operation, but the attackers kept about 600 Bitcoin; the network was working to restore one-to-one backing and re-enable authorized peg-outs.
Keon said an attacker withdrew roughly 4,000 BTC from Liquid, returned about 3,600 BTC, and kept roughly 400 BTC as a claimed bounty. Liquid’s blocks were running again, but normal peg-outs remained unavailable after 30 days; Keon said Blockstream could restore the peg, take a haircut from users, or leave funds trapped.
Marty Bent criticizes Blockstream for poor crisis communication during the Liquid Network exploit. The incident, paired with Coldcard's move away from open-source licensing, underscores how restricting code access limits independent security developer audits.
Blockstream's post-mortem of the September 6 exploit revealed that a patch for a 2018 range-proof cache bug introduced a secondary vulnerability. The attacker used this flaw to mint L-BTC, pegging out 3,996 Bitcoin through the SideSwap interface.
The Liquid network remains roughly six hundred Bitcoin short following a security incident, with peg-outs to on-chain Bitcoin remaining paused. Blockstream stated that redemptions will not resume until the one-to-one asset backing is verified and audited.
Blockstream's federated Liquid Network experienced a hack of 4,000 Bitcoins, with a white hat returning 3,400 Bitcoins. Simon Dixon claims the subsequent network freeze highlights the core differences between decentralized Bitcoin and centralized, federated scaling solutions.
Blockstream's Liquid Network suffered a hack of 4,000 Bitcoin, exposing security vulnerabilities in federated sidechains. A white-hat hacker returned 3,400 Bitcoin, leaving a 600 Bitcoin deficit that required Blockstream to freeze the network to negotiate.
Francis Hunt links Adam Back's linguistic style and Blockstream's early Jeffrey Epstein-connected funding to Satoshi Nakamoto. Simon Dixon counters that cryptographer Len Sassimon is a more plausible candidate, having committed suicide shortly after Gavin Andresen met with the CIA.
Simon Dixon confirms that Blockstream, founded by Adam Back in 2014, received early funding connected to Jeffrey Epstein through MIT's Joi Ito. Simon Dixon notes that Back has never publicly refuted allegations of visiting Epstein's private island with co-founder Austin Hill.
Liquid Network attackers returned 3,400 of the 4,000 stolen Bitcoin but kept nearly 600 coins as a ransom. Adam Back confirmed the Liquid peg will remain fully covered one-to-one, while Blockstream refuses to negotiate with the hackers.
Blockstream communicated with the Liquid hacker via PGP-encrypted onchain messages before the attacker threatened to publish negotiations in plain text. Blockstream plans to pursue every legal avenue to recover the remaining 600 stolen Bitcoin.
Security researcher Cali publicly claimed Blockstream could have avoided the Liquid exploit by answering red team emails. Keon criticizes this as clout-chasing influencer behavior, arguing that effective security work must be conducted quietly.
Ezra Regreira reports that Blockstream refused to pay a 10% ransom to hackers who exploited the Liquid Network federation wallet. The hackers initially withdrew 4,000 Bitcoin but returned 3,400 after Blockstream patched the affected bridge nodes.
Blockstream Liquid was hacked for 4,000 BTC after an attacker exploited an inflation vulnerability. The exploit resulted from a flawed code patch released on September 1, 2024, which attempted to fix an older 2018 range proof vulnerability.
Adam Back announced the Liquid network peg will remain one-for-one. Blockstream and its partners are plugging the remaining 600 BTC deficit after the hacker returned 3,400 BTC through encrypted OP_RETURN negotiations, keeping 15 percent as an unsolicited bounty.
The attacker communicated with Blockstream via on-chain OP_RETURN and PGP-encrypted messages, claiming they would return the funds once all nodes are patched. Max remains skeptical of a return, while q and a expects the attacker to comply.
Jack Mallers explains that Blockstream's Liquid sidechain suffered a $300 million exploit of 4,000 BTC due to a caching bug, not a failure of Bitcoin's core cryptography. The attacker has since returned 3,400 BTC.
Blockstream's 2014 white paper proposed sidechains to test features like confidential transactions without modifying Bitcoin. Jack Mallers notes this allows experimental layers to fail safely without jeopardizing Bitcoin's core monetary rules.
Alleged white-hat hackers moved 4,000 Bitcoin out of Blockstream’s Liquid sidechain, representing roughly 95% of the total pegged-in funds. Marty Bent and John Arnold emphasize that while the situation remains active, it has not yet resulted in a permanent loss of funds.
Marty Bent highlights Blockstream's ongoing development of BIP Shrinks, a proposed quantum-resistant signature scheme. John argues that establishing multiple cryptographic schemes is vital to eliminate single points of failure in Bitcoin's security model.
Blockstream researchers Jonas Nick and Mikhail Kudinov proposed Shrinks, a cryptographic signature scheme designed to protect Bitcoin against quantum computing. The protocol generates signatures using SHA-256 and maintains higher transaction speeds than generic post-quantum alternatives.
John Carvalho questions Blockstream's commercial viability, noting that its sidechain project Liquid has low market adoption. He suspects Blockstream's actual strategy is holding Bitcoin while building free infrastructure to drive asset appreciation.
Wuckert Jr. describes Tether and Bitfinex as the Tetheral Reserve. He argues their massive investments in block size status-quo entities like Blockstream allow them to leverage unbacked token issuance to consolidate power.
