The Blockchain Trilemma states that you can typically only optimize for two of three features: Decentralization, Security, and Scalability. Each Layer 1 tackles this trilemma differently.
The Top Layer 1s Visualized
Ethereum (ETH): Optimized for Security and Decentralization. Relies on Layer 2s for Scalability. The undisputed king of DeFi and TVL liquidity settlement.
Solana (SOL): Optimized for Scalability. Monolithic design processes thousands of TPS on the main chain. Extremely cheap, favored for retail trading, DePIN, and high-frequency use cases.
XRP Ledger (XRP): Optimized for Global Payments and FX. Federated Consensus algorithm means it doesn't need PoW or standard PoS. Settles in 3 seconds at a fraction of a cent. The undisputed king of cross-border institutional transfers.
Avalanche (AVAX): Optimized for Subnets. A highly customizable architecture allowing enterprises to deploy their own blockchains (subnets) that inherit Avalanche's consensus.
