Ethereum Layer-2 Blockchain Linea Halted After Hack: Importance of Decentralization, Says Matter Labs CEO

The recent hack on Ethereum layer-2 blockchain Linea has sent shockwaves through the crypto community, prompting discussions on the importance of decentralization in the space. The decision to halt block production after the hack has raised concerns about the security of layer-2 firms and the need to prioritize decentralization.

According to Alex Gluchowski, CEO of Matter Labs, the incident highlights the urgency for layer-2 firms to decentralize sooner rather than later. The hacker managed to exploit Linea-based decentralized exchange Velocore, resulting in the transfer of over $2.6 million in Ether. While Linea has since resumed block production, Gluchowski emphasized the importance of decentralizing the sequencer to prevent such incidents in the future.

In response to Gluchowski’s comments, Linea’s product lead, Declan Fox, acknowledged the need for decentralization but assured that the network is on a solid path towards achieving it. The firm recently announced its campaign to increase the total value locked on Linea to $3 billion, despite criticism from some observers in light of the recent hack.

The Linea team described the decision to halt block production as a “last resort” action to protect users on the platform. They were notified of the hack by Hexagate and took immediate steps to prevent further funds from being bridged out. The hacker exploited Linea-based DEX Velocore, moving a significant amount of Ether off the platform via a third-party bridge.

Despite the incident, Linea remains committed to decentralizing its network in the future, including the sequencer, to prevent similar attacks. Velocore has also pledged to work with external networks to reimburse impacted victims.

The hack on Linea serves as a reminder of the risks associated with centralized layer-2 solutions in the crypto space. As the industry continues to evolve, the need for decentralization and security measures becomes increasingly crucial to protect users and their funds.
