PANews reported on October 27th that Solana co-founder Toly, in a post on the X platform, pointed out that the current Layer 2 network has fundamental security issues. He believes that building a complete Layer 2 network code is complex and has a wide attack surface, making it difficult to guarantee vulnerability-free and fully functional. To this end, existing Layer 2 networks generally adopt upgraded multi-signature mechanisms, but this renders all security guarantees meaningless. Toly emphasized that Layer 2 and the cross-chain bridge Wormhole face the same extreme risk: multi-sig can mobilize all bridged funds. In contrast, even if validators on chains like Sui achieve 100% staked support, they cannot unilaterally change the state without coordination from major exchanges and RPC nodes. However, Layer 2 multi-sig can directly upgrade bridge contracts and transfer funds. He explicitly refuted the claim that "Layer 2 inherits Ethereum's security," pointing out that five years after the L2 roadmap is implemented, Ethereum funds bridged by Wormhole on Solana face the same extreme risks as Ethereum funds on the Base chain, while generating comparable returns for Ethereum L1 stakers. Toly believes that Layer 2 has insurmountable security issues, which is why it has not achieved true security in the past five years.
