$SOL Solana (SOL) and Ethereum (ETH) have significant differences in design and goals.

Solana pursues high performance and adopts a unique Proof of History (PoH) consensus mechanism, which has fast transaction speed and low cost. However, the degree of decentralization is relatively weak, and the network has been interrupted many times.

Ethereum focuses on decentralization and security, provides wider decentralized application support through Proof of Stake (PoS), and has a mature developer community, but transaction speeds are slower and fees are higher.

The applicable scenarios of the two are different. Solana is suitable for high-frequency transactions, while Ethereum is more suitable for complex DApp ecology.
