Bitcoin sidechain Liquid halts after white hats withdraw $320M BTC

This incident underscores the fragility of federated sidechains, where a single exploit can freeze network operations and force reliance on the goodwill of anonymous actors. The pause affects all Liquid users and issuers of assets on the chain, highlighting custodial and technical risks inherent in this design. The key question is whether the promised return of funds materializes and how quickly Blockstream can coordinate a patch across all parties, as the outcome will set a precedent for trust in similar Bitcoin layer-2 solutions.
