The Monolithic Scaling Philosophy
While Ethereum scales modularly through Layer-2 rollups and external data availability layers, Solana scales at the base layer. By executing transactions in parallel on high-performance validator hardware, Solana achieves sub-second finality and high transaction throughput without rollup fragmentation.
How Local Fee Markets Protect Normal Users
On traditional single-fee blockchains, a popular NFT mint or meme-coin surge drives up gas prices across the entire network. Solana’s local fee market architecture charges higher priority fees only on transactions interacting with the congested account, keeping standard peer-to-peer transfers inexpensive.
Client Diversity and the Firedancer Upgrade
Historically, Solana relied primarily on a single validator client implementation. The introduction of Firedancer, a C++ validator client engineered from the ground up for high-frequency financial performance, provides independent client diversity and protects the network against single-codebase outages.
