Blockstream Demands Return of 4,000 Bitcoin from Liquid Network Exploiters

Blockstream publicly demanded the return of remaining Bitcoin from exploiters who drained over 4,000 BTC from its Liquid Network sidechain, rejecting claims for a "white hat" reward. This ultimatum anchors a significant dispute over the substantial funds taken from the Bitcoin sidechain. ## Liquid Network Exploit Details The incident involved the compromise of Blockstream's Liquid sidechain, leading to the unauthorized exfiltration of over 4,000 bitcoin. The exploiters have identified themselves as "white hat hackers" and expressed intent to keep a portion of the stolen assets, a position Blockstream disputes. While specific technical details of the vulnerability were not disclosed, the outcome was the successful transfer of funds. Blockstream's public demand signals a firm stance against the exploiters' terms, indicating a lack of negotiation regarding a reward. The company is actively pursuing the full recovery of the remaining funds. This event shows persistent security risks associated with sidechains and cross-chain bridges within the broader crypto market. ## Bitcoin Market Reaction Bitcoin (BTC) trades at $77,376 as of 2026-09-11, data.
