Top 20 Layer 1 Projects for 2025
1. Bitcoin (BTC)
Bitcoin remains the gold standard for decentralized digital currency, prioritizing security and scarcity. Its PoW consensus ensures robustness, though newer Layer 1s challenge its scalability.
2. Ethereum (ETH)
Ethereum’s transition to PoS (Ethereum 2.0) enhances scalability and reduces energy use, solidifying its position for DeFi and smart contracts.
3. Solana (SOL)
Solana’s hybrid PoH+PoS mechanism enables ~65,000 TPS, making it ideal for high-frequency dApps and NFT marketplaces.
Selection Criteria for Top Projects
- Scalability: High TPS without compromising decentralization.
- Security: Audited protocols and attack-resistant consensus.
- Ecosystem Growth: Vibrant developer communities and dApp adoption.
- Sustainability: Energy-efficient mechanisms like PoS.
