What exactly is a blockchain client? It's the software layer that enforces all the blockchain's rules and keeps every node connected and synchronized across the network.

Firedancer stands out as a lightning-fast implementation of this client, purpose-built for Solana's ecosystem. The architecture is optimized for throughput and speed.

Then there's Fogo, which takes things further by running its own customized fork of Firedancer. This allows for specialized optimizations tailored to their specific needs.
