As an experienced blockchain analyst, I believe the recent suspension of block production on Consensys’ Linea Layer 2 blockchain following a security compromise is a necessary yet unfortunate step to safeguard user assets and preserve network integrity.
Notable occurrence in the blockchain realm: Consensys’ Linea, a Layer 2 blockchain solution, has halted block creation temporarily after a security breach resulted in the theft of funds valued at millions. This action aims to shield user assets from further exploitation and uphold the network’s authenticity.
Based on the TOBTC trading platform’s report, there are plans to restart production and decentralize Ethereum‘s network soon. However, this event underscores the importance of Ethereum layer-2 solutions such as Linea to strengthen decentralization initiatives.
Linea Blockchain Swoops In To Save The Day
On June 2, 2023, I identified an incident involving the Velocore decentralized exchange, which operates on the Linea network. A hacker exploited vulnerabilities in this platform and executed a malicious action through a third-party bridge. The result was the successful extraction of over 700 Ethereum (ETH), equivalent to approximately $2.6 million, from the blockchain.
Hexagate was the initial discoverer of the hack in Linea’s observation, revealing the culprit’s addresses, exposing vulnerable smart contracts, and tracing the pilfered funds. Unfortunately, the disparity in time zones impeded immediate contact between the blockchain and Velocore’s team.
As a researcher studying blockchain technology, I’ve encountered an instance where the platform momentarily halted the production of new blocks. This pause revealed the vulnerabilities of centralized control in mitigating further damage. In response to this exploit, with no other viable options, our team had to temporarily shut down the sequencer to prevent any more funds from being transferred out.
Linea implemented a ” emergency measure” to temporarily halt the fabrication of blocks at positions 5081800 and 5081801, ensuring the safety of its users from potential further harm.
During the intermission, the blockchain enabled Velocore’s team to examine the vulnerability. They also concealed the identities of the hackers, significantly reducing harm to Linea consumers’ ecosystem. As other L2 platforms, we are in the ‘learning phase,’ providing us with protective measures.
“Linea aims to decentralize its network, which includes the sequencer. Once the network becomes fully decentralized and censorship-resistant, the team will no longer have the ability to halt block creation or restrict specific addresses.”
The Decision Was Not Taken Lightly
As a crypto investor, I’ve noticed that most L2 (Layer 2) solutions, including Linea, still rely on centralized technical operations for their functioning. This means that there are entities with the power to make decisions and safeguard the ecosystem. While this approach may offer security, it goes against the very essence of Linea’s founding principles – a permissionless, censorship-resistant environment where everyone is in control. Making the decision to move away from centralized technical operations was not an easy choice for me, given these conflicting priorities.
The platform highlighted a major concern leading to its shutdown of the sequencer: the hacker’s obtaining of tokens followed by their sale into Ethereum. This breach not only emptied the liquidity pool but also posed potential risks for users within the ecosystem.
As an analyst, I’ve noticed that our team has emphasized its dedication to ensuring user safety by enhancing comprehensive threat surveillance and defense systems. These advanced measures were effectively implemented during the recent cyber attack.
