Solana Founder Raises Concerns About Ethereum L2 Security — Is It a Real Threat or Just Competition?

Anatoly Yakovenko, one of Solana Labs' founders, recently raised concerns about the security of Ethereum layer 2 solutions.
According to him, Ethereum L2 solutions may not be fully protected against future quantum threats. He even went as far as to say that “we should forget any hope for an easy fix,” indicating that the problem might be deeper than many think.
He also pointed to greater fears — the possibility that advanced artificial intelligence systems could eventually break post-quantum cryptographic signatures (PQC) in the future. If that happens, it could impact not only Ethereum L2 but the security of the entire blockchain.
This statement sparked a new debate in the crypto space about how secure current systems are and whether the industry is truly prepared for future technological threats like quantum computing and artificial intelligence.
Now, the big question:
Is he really raising valid concerns, or is he just attacking Ethereum L2 because of competition?
In reality, it involves both.
On one hand, competition between ecosystems like Solana and Ethereum naturally leads to criticism.
On the other hand, the risks of quantum computing and AI are real discussions already ongoing across the entire blockchain industry.
So, instead of dismissing them as mere competition, it’s better to see them as a wake-up call — a reminder that blockchain security must continue to evolve with technological advances#f
