The Blockchain Trilemma
Security, scalability, and decentralization — you can only fully optimize two. Ethereum prioritizes security and decentralization. Solana bets on speed and scalability, with some tradeoffs.
Transaction Speeds
Ethereum Layer 1 handles ~15 TPS. With Layer 2 rollups, this scales to thousands. Solana claims 65,000 TPS but has faced outages raising reliability concerns.
Developer Ecosystem
Ethereum wins hands down on tooling, documentation, and developer community. Solana is catching up fast but still has years to go.
