-
Debate Over Security: Vitalik Buterin defends Ethereum’s Layer-2 networks, asserting that a 51% validator collusion wouldn’t lead to asset theft, while acknowledging limitations in custom control tasks.

Yakovenko’s Counterpoint: Anatoly Yakovenko disputes Buterin’s claims, stating that Ethereum’s L2s do not inherit true security and emphasize the inherent risks and complexities that compromise decentralization and auditability.
-
Multisig and Off-chain Risks: Yakovenko highlights security vulnerabilities in multisig setups and off-chain execution, which can centralize control and create potential for fund mismanagement without user consent.

Proposed Bridge Solution: Yakovenko suggests Ethereum operate as a Layer-2 on Solana through a dedicated bridge, facilitating asset movement without modifying the blockchain structure.
Vitalik Buterin and Anatoly Yakovenko Clash Over Ethereum’s Layer-2 Security
A public exchange between Ethereum co-founder Vitalik Buterin and Solana co-founder Anatoly Yakovenko has drawn significant attention in the crypto community. This debate highlights the security concerns surrounding Ethereum’s Layer-2 (L2) networks.
First, Buterin defended Ethereum’s L2 architecture on X. He argued that, even if 51% of validators collude or encounter a software bug, they cannot steal user assets. However, he recognized limitations when validators manage tasks beyond the chain’s control. In such cases, collusion could lead to false outputs without recourse.
Conversely, Yakovenko challenged Buterin’s views. He asserted that the belief that L2s inherit Ethereum’s security is incorrect. He stated, “The promise of L2s != the reality of L2s.” He cited issues with L2 implementation, noting that five years into the roadmap, Wormhole ETH on Solana faces similar risks as ETH on Base, despite generating comparable revenues for Ethereum Layer 1 (L1) stakers.
Yakovenko identified inherent flaws in L2 networks, emphasizing how complex codebases create broad attack surfaces that are hard to audit. He added that multisig custody setups can enable fund transfers without user approval when signers cooperate or are compromised. Furthermore, he expressed concern that off-chain execution systems concentrate too much power in a few hands, contradicting the decentralization that blockchain aims to achieve.
In a striking proposal, Yakovenko suggested establishing a dedicated bridge that would allow Ethereum to function as a layer-2 on Solana. This move could facilitate smoother asset transfers between the two platforms without necessitating changes to the blockchain itself. He noted that as zero-knowledge proving advances, the implementation would become increasingly feasible.
Proponents of Ethereum, like crypto lawyer Gabriel Shapiro, argue that the vast validator base—over one million active validators—reinforces its security. He clarified that L2s are more than just simple servers running a blockchain. Since they are linked to Ethereum, certain transactions can be enforced within blocks, minimizing the need for decentralization at the L2 level.
This ongoing discussion emphasizes the continuous evolution of blockchain technology. As developers address security and decentralization challenges, innovative solutions could reshape the future of decentralized finance.
