Blockstream Tells Hackers To Return Remaining Bitcoin Stolen in Liquid Theft

Blockstream has called on white-hat hackers who targeted its Liquid sidechain to return the Bitcoin still held from the incident. The hackers took over 4,000 BTC during the theft and have indicated that they want to keep part of the funds as a reward. Blockstream has rejected that position and is seeking the return of the remaining Bitcoin. The development was reported by Bitcoin Magazine on September 11, 2026. Liquid is a Bitcoin sidechain associated with Blockstream, while the incident involves BTC held through the network. No further details about the amount still outstanding or the terms of any proposed reward were provided in the available report. The dispute leaves the recovery of the stolen Bitcoin unresolved and remains relevant to market participants monitoring BTC-related infrastructure and security incidents.
