Ethereum's biggest competitor is currently considered to be Binance Smart Chain (BSC). BSC is a blockchain platform that runs parallel to the Binance Chain and aims to provide a high-performance infrastructure for decentralized applications (DApps) and smart contracts. BSC has gained popularity due to its lower fees and faster transaction processing times compared to Ethereum. Other notable competitors include Cardano, Polkadot, and Solana, which also offer scalability and flexibility for decentralized applications.
