币界网报道：Ethereum developers and industry leaders gathered at the Ethereum Summit in Cannes to discuss the network's scalability challenges and the growing role of rollup technology in addressing them. Key speakers highlighted that Ethereum's current throughput limitations remain a critical bottleneck, especially with rising demand for decentralized applications (dApps) and DeFi protocols. Rollups, particularly Optimistic and ZK-Rollups, were emphasized as the most promising short-to-medium-term solutions to enhance transaction speed and reduce gas fees. Vitalik Buterin reiterated the importance of Layer 2 scaling, noting that Ethereum's roadmap prioritizes rollup-centric development while the community awaits the full implementation of sharding. Several projects showcased rollup-based solutions at the summit, with StarkWare and Arbitrum presenting case studies demonstrating significant improvements in transaction throughput. Panelists also debated the trade-offs between security, decentralization, and scalability, acknowledging that no single solution perfectly balances all three. The event concluded with a call for greater collaboration between developers, validators, and dApp builders to accelerate rollup adoption and ensure seamless interoperability across Layer 2 networks.
