Episode notes
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.
Performance Limits Drive Network Issues
- Many problems on Solana, like transaction reordering or delay tactics, stem from performance limitations tied to compute unit constraints.
- Increasing compute limits can reduce gaming of block production and improve network latency and capacity.
Protocol and Social Fixes
- Problems like excessive block time are best solved at the protocol level with explicit mechanisms like Alpenglow's block timing votes.
- Social consensus and transparency also help reduce issues like sandwich attacks where protocol fixes are lacking.
