According to Crypto Rover, Vitalik Buterin emphasized that Ethereum Layer 1 scaling must enhance transaction speed while maintaining node usability, signaling a strategic focus from the Ethereum Foundation on both performance and decentralization (source: Crypto Rover on Twitter, May 19, 2025). This development is highly relevant for ETH traders as it suggests potential upgrades aimed at increasing network throughput without sacrificing the ability of individual users to run full nodes, which is crucial for security and decentralization. Improved scalability could drive higher transaction volumes and enhance Ethereum's competitiveness against other smart contract platforms, impacting ETH price action and market sentiment.
