Liquid Network Restarts After $320 Million Bitcoin Exploit
Liquid Network, a Bitcoin sidechain developed by Blockstream, lets users transact with LBTC, a token meant to be backed one-for-one by bitcoin held by the network's federation. A critical vulnerability allowed attackers to remove nearly 4,000 bitcoin, worth about $320 million, from the network. The breach raised questions about the adequacy of Liquid's reserves, the security of the bridge linking it to Bitcoin's main chain, and the safeguards protecting assets moved off the base layer.
Liquid halted block production after the incident emerged around Sept. 8, while major exchanges suspended LBTC deposits and withdrawals. The attackers, who described themselves as white hats, later returned 3,400 bitcoin, leaving roughly 598 bitcoin valued at about $47 million outstanding. Blockstream confirmed the returned funds on-chain and said negotiations over the remainder continue. Block production has since resumed after emergency fixes, but the episode underscores how much trust bridge designs still require from users.
Why it made the coverWe lead with it because recovery mechanics matter more to readers than the theft itself: the reopening sets a precedent for how federated chains handle catastrophic loss.
