Liquid Network Resumes Block Production After $320M Bitcoin Withdrawal

Outage and Recovery

Liquid Network halted and then resumed block production Thursday following a $320 million Bitcoin withdrawal that depleted its reserves by 95%, according to updates from the sidechain's operators. Functionary nodes—the validators responsible for confirming transactions—began producing blocks again, though the network did not immediately process pending transactions during the initial restart phase.

What the Incident Exposed

The withdrawal and subsequent halt highlight structural vulnerabilities in Liquid's federated consensus design, where a limited set of functionaries control block production and asset custody. The near-total reserve drawdown in a single event raises questions about the adequacy of Liquid's security model and the concentration risk inherent in sidechain architectures that rely on a federation rather than a dispersed validator set.

Network Status and Next Steps

The cause of the $320 million withdrawal and the timeline for resuming normal transaction processing were not detailed in available statements. Liquid Network is a Bitcoin sidechain operated by Blockstream and used primarily for faster settlement and confidential transactions among institutional participants and exchanges.
