Cardano (ADA), Ethereum (ETH), and Solana (SOL) represent three distinct visions for the future of blockchain technology. Ethereum, the earliest of the trio, pioneered smart contracts and remains the foundation for a vast ecosystem of decentralized applications, DeFi protocols, and NFTs. Its transition toward proof-of-stake has aimed to improve scalability and reduce energy consumption while maintaining strong security and decentralization.
