Ethereum’s dominance in DeFi is currently substantial, but it faces growing threats from emerging blockchains. Challengers like Solana, Avalanche, and layer-1 solutions offer higher throughput and lower transaction costs, addressing Ethereum’s scalability issues. These networks are attracting developers and users with their advanced features and user-friendly environments. However, Ethereum is not standing still. With the transition to Ethereum 2.0 and the implementation of sharding, it aims to significantly improve scalability while maintaining its robust security and decentralization. While emerging blockchains pose a threat, Ethereum’s established ecosystem, extensive developer community, and ongoing upgrades make it resilient. The future may see a multi-chain DeFi landscape, but Ethereum’s position remains strong
