Gnosis Chain Hard Fork Recovers Millions Lost in Balancer Exploit
The Gnosis Chain executed a hard fork on December 22 to recover around $9.4 million in frozen funds after November's Balancer exploit.
The attack, which affected liquidity pools across multiple networks including Ethereum and others, resulted in a $128 million loss for Balancer.
Gnosis initially implemented a soft fork to freeze the stolen funds on its network, but this was insufficient to recover the assets. The hard fork activated at 16:11 UTC following a governance-approved proposal and included penalties for validators who failed to upgrade their nodes, ranging from suspended staking rewards to potential slashing.
The decision sparked debate within the crypto community over blockchain immutability principles, with some arguing that it compromised these principles while others saw it as necessary to protect affected users. According to Philippe Schommers, Gnosis' head of infrastructure, the team aimed to enable fund recovery by Christmas and maintained that the hard fork required 'relatively minor changes that do not affect chain history.'
