‍#Gate广场五月交易分享 Solana Foundation Announces Post-Quantum Security Step; Concerns Rise for Ethereum Layer 2 (L2) The Solana Foundation has launched the Falcon signature algorithm on its network for post-quantum security. The current security structure of Ethereum Layer 2 wallets may be vulnerable to powerful quantum computers. This innovation on the Solana network is a first step towards addressing quantum threats while maintaining high transaction capacity. Critical point: The $SOL ecosystem is following a strategic roadmap in preparation for next-generation attacks. Solana CEO Anatoly Yakovenko raised the issue of quantum computer threats to blockchain security. In a statement on social media on May 2, 2026, he stated that current Ethereum Layer 2 solutions are not secure against quantum attacks. Yakovenko also pointed to new technologies developed by the Solana ecosystem to address this threat. Quantum Threat and Blockchain Security Anatoly Yakovenko, a developer by profession, is the founding visionary of the Solana blockchain. At Solana, he leads a team that makes significant investments in developing long-term solutions to address the latest emerging risks in blockchain security. Recently, the Solana Foundation announced a critical milestone in post-quantum cryptography. In this context, it was revealed that Anza and Firedancer, technical teams at Solana, have chosen the Falcon digital signature algorithm for post-quantum security, and the first applications of this technology have been shared on GitHub. According to blockchain analysts, the 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 rely on the Elliptic Curve Digital Signature Algorithm. The fact that public keys become visible during transactions means that quantum computers could potentially crack these keys in the future. Experts state that attackers could use a "gather now, decrypt later" method to decrypt transaction data using quantum technology at a later date. Quantum technology, which threatens current encryption protocols, is not limited to the Ethereum ecosystem; large networks like Solana and Bitcoin are also said to face similar risks. Currently, it is stated that these threats are medium to long-term, but all blockchains fundamentally share the same vulnerabilities. Solana's strategic approach and roadmap The Solana Foundation announced that it has prepared a phased transition plan to prepare the network for next-generation quantum attacks. The roadmap outlines that innovations will begin with research and updates at the wallet level, then progress to broader protocol updates. Development teams stated that thanks to the performance of the Falcon digital signature algorithm and short signature sizes, the high transaction throughput and efficiency goals of the Solana network will not be compromised. However, there will not be an abrupt protocol change on the Solana network yet; developments will be gradually implemented in parallel with advancements in quantum computing. An official statement from the Solana Foundation said, "Our roadmap envisions research and wallet-level updates first, and then broader protocol transformations if necessary, rather than rapid changes." Layer 2 discussions and industry impact Yakovenko also drew attention to the economic structure of Ethereum Layer 2 solutions. He stated that different rollups and on-chain layer solutions divide liquidity and fragment user communities. This situation can also negatively affect interaction and revenue distribution on the main chain. Some figures in the Ethereum ecosystem, however, argued that Layer 2 systems are inevitable for the long-term growth of the network. While they may bring some short-term disadvantages, the view that they play a significant role in terms of performance and scalability is also gaining traction within the industry. Blockchain developers have begun testing post-quantum cryptography solutions to achieve a new level of security. However, it is emphasized that transitioning to entirely new cryptographic standards on active and large networks is technically complex and time-consuming. Consequently, as quantum computers become more widespread, the security of the decentralized blockchain ecosystem appears to be driven by new discussions and technical advancements across the industry. ‍$SOL
