Ethereum ( #ETH ): The largest smart contract platform, transitioning fully to energy-efficient proof-of-stake. Huge developer ecosystem.

Solana ( #SOL ): High-speed, low-fee transactions. Popular for gaming and DeFi projects.

Avalanche (#AVAX ) & Polygon (MATIC): Focused on scalability and cheaper transactions.
