Big moment for Solana—Firedancer, the high-performance validator client that's been in development for 3 years, just went live on Solana Mainnet. The early validators running it have already clocked 100 days of continuous operation, successfully producing 50,000 blocks.

For those not following the technical side: Firedancer is essentially a ground-up rebuild of the validator infrastructure, designed to handle higher throughput and lower latency compared to the original Agave client. Jito's team led this effort, and it's basically what enables Solana to push toward those massive TPS numbers people keep talking about.

The fact that it's been running stable for 100 days on mainnet validators is the real story here—that's not a testnet flex, that's production-grade validation. This kind of infrastructure upgrade is the boring but critical work that actually moves blockchains forward.
