Liquid Network Attackers Pledge to Return 4,000 BTC After Vulnerability Patch

In the early hours of a seemingly quiet trading session, whispers spread through the Bitcoin ecosystem like an unconfirmed order in the mempool. Reports surfaced that attackers had exploited a vulnerability on Liquid Network, the Bitcoin sidechain developed and operated by Blockstream. They made off with roughly 4,000 BTC before publicly committing to return the vast majority after the team would fix the flaw. The news hit fast—too fast for traditional media to confirm details, too slow for the market to ignore. This is no simple rug pull. This is a pressure test on one of the most discussed infrastructure layers in Bitcoin finance.
