Episode notes
Firedancer's Dual Client Journey
- Firedancer has two components: Frankendancer, live with around 10% stake, and the full Firedancer still in development.
- The biggest challenge has been ensuring conformance, making sure both clients produce identical results to avoid network halts.
Conformance Challenge Complexity
- Solana's ecosystem moves rapidly with frequent protocol changes, making client conformance a moving target.
- Lack of formal specification means developers must reverse-engineer behaviors, including Rust-specific nuances, to match Solana's validator behavior exactly.
TPS vs Economic Value
- TPS is best measured by economic value, proxied by fees users pay, not just transaction count.
- Current compute unit limits cap TPS around 1-2k transactions per second despite Firedancer's ability for much higher throughput.
