Layer-1 Blockchains Compete for Dominance**

Next-generation **Layer-1 networks** are challenging Ethereum’s hegemony. **Solana** remains a top contender due to its high-speed transactions (3,500+ per second) and low fees, with developers voting on protocol upgrades to improve staking rewards and inflation controls. Meanwhile, **Sui Network**, built by Meta’s former Diem team, uses parallel processing and the Move programming language to achieve unmatched scalability. Its ecosystem has seen explosive growth in DeFi and NFT applications, with speculation about a potential SUI ETF. **Avalanche** and **Cardano** are also gaining traction, focusing on eco-friendly consensus mechanisms and institutional-grade smart contracts.
