Solana Labs CEO Anatoly Yakovenko brought up the quantum computer threat regarding the security of blockchains. In a statement on social media platform X on May 2, 2026, he stated that current Ethereum Layer 2 solutions are not quantum safe. Yakovenko also pointed out the new technologies developed by the Solana ecosystem against this threat.
Quantum threat and blockchain security
As a leader from a developer background, Anatoly Yakovenko is the founding visionary of the Solana blockchain. As Solana, he manages a team that makes significant investments to develop long-term solutions against the latest risks in blockchain security.
Recently, the Solana Foundation announced that a critical milestone has been achieved in the field of post-quantum cryptography. In this context, it was announced that Anza and Firedancer, among the technical teams at Solana, preferred the digital signature algorithm called Falcon for post-quantum security and the first applications of this technology were shared on GitHub.
According to blockchain analysts, current security standards used by Ethereum Layer 2 solutions may not provide sufficient protection against attacks from advanced quantum computers. The majority of Layer 2 wallets are based on the secp256k1 curve and the Elliptic Curve Digital Signature Algorithm (ECDSA).
The fact that public keys become visible during the transaction means that quantum computers can crack these keys in the future. Experts stated that attackers could use the “collect now, decrypt later” method to decrypt transaction data with quantum technology at a later date.
Quantum technology that threatens existing encryption protocols is not limited to the Ethereum ecosystem; It is stated that large networks such as Solana and Bitcoin face similar risks. For now, it is reported that these threats are medium and long-term, but all blockchains have essentially the same vulnerabilities.
Solana’s strategic approach and road map
Solana Foundation announced that it has prepared a phased transition plan to prepare the network for next-generation quantum attacks. In the prepared road map, innovations will first begin with research and updates at the wallet level, and then progress to broader protocol updates.
Developer teams stated that thanks to the performance of the Falcon digital signature algorithm and short signature sizes, the high transaction volume and efficiency targets of the Solana network will not be compromised. However, there will be no sudden protocol changes in the Solana network yet; The developments will be gradually transferred to the system in parallel with the advances in quantum computers.
In the official statement made by the Solana Foundation, the statement was made: “Rather than rapid changes, our roadmap envisages first updates at the research and wallet level, and then, if necessary, broader transformations in the protocol.”
Layer 2 discussions and industry impact
Yakovenko also drew attention to the economic structure of Ethereum Layer 2 solutions. He noted that different rollups and on-chain layer solutions divide liquidity and fragment user communities. This may also negatively affect interaction and revenue distribution on the main chain.
Some names in the Ethereum ecosystem argued that Layer 2 systems were inevitable for the long-term growth of the network. Although it may bring some disadvantages in the short term, the view that it plays an important role in terms of performance and scalability is also accepted within the industry.
Blockchain developers have begun testing post-quantum cryptography solutions to achieve a new level of security. On the other hand, it is emphasized that the transition to completely new cryptographic standards in active and large networks is technically complex and time-consuming.
As a result, as quantum computers become more widespread, the security of the decentralized blockchain ecosystem seems to be driven by new discussions and technical developments across the industry.
