Solana co-founder Anatoly Yakovenko challenged the security and decentralization claims of Ethereum’s layer 2 scaling networks during a heated debate on X on Sunday. He argued that these networks face significant security vulnerabilities and centralization issues that contradict their stated benefits.

Yakovenko contended that layer 2s feature massive attack surfaces with code bases too large for proper software bug audits. He added that user funds can be moved from L2s without consent because these networks rely on multi-signature custody arrangements.

“The claim that layer 2s inherit Ethereum security is erroneous,” Yakovenko stated. He added that “5 years into the L2 roadmap, wormhole eth on solana has the same worst case risks as eth on base and generates as much revenue for eth L1 stakers.”
