Anatoly Yakovenko, co-founder of Solana, recently voiced strong criticism of Ethereum's Layer 2 scaling solutions, labeling the model as "fundamentally broken" in a series of posts on X (formerly Twitter) on October 26-27, 2025. This assertion has ignited significant debate within the cryptocurrency industry regarding the security and decentralization of these scaling mechanisms.
Yakovenko's claims directly challenge the perceived security guarantees of Ethereum's Layer 2 solutions, potentially leading to technical discussions and market volatility affecting Ethereum (ETH), Solana (SOL), and various Layer 2 governance tokens.
Yakovenko: L2 Models Pose Security Risks
Anatoly Yakovenko, a prominent figure in the blockchain space, has raised concerns about Ethereum's Layer 2 security. In public Twitter posts, he criticized L2 models for failing to guarantee secure decentralization.
Yakovenko stated that Layer 2 solutions rely on complex codebases and multisignature (multisig) arrangements, which introduce inherent security risks. This critique of Ethereum's scaling approach has spurred new debates among developers and market participants. He further elaborated, "The claim that L2s inherit eth security is erroneous. 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. It’s wrong no matter how you slice it."
Security Concerns May Influence Trade Strategies
Yakovenko's critique is expected to impact the perception of Ethereum's scalability solutions. Concerns over the security of Layer 2 networks could influence trading strategies between Ethereum and Solana, potentially affecting their respective asset valuations.
Industry stakeholders are reportedly reassessing Layer 2 security, which may lead to shifts in institutional and retail market allocations. The criticism highlights the potential for a move back towards high-throughput alternatives, such as Solana.
Bridge Exploits Highlight L2 Vulnerabilities
Criticisms regarding Layer 2 security are not a new phenomenon. Past incidents, including bridge exploits and concerns about centralization, have previously brought these issues to the forefront. These ongoing debates reflect persistent tensions within the blockchain industry concerning the development of secure scaling solutions.
Potential outcomes from these discussions could include a migration to alternative networks or the implementation of enhanced Layer 2 security protocols. Historical trends suggest that such criticisms may prompt technological advancements or increased regulatory scrutiny.
