Doing our piece to scale Solana for all builders - latency, throughput and scale at the RPC layer! Thank you @afscott for the opportunity to chat!
If you're building on Solana today, this convo is for you. 💥 Our CTO @gponcin joined @afscott to break down: - Why Solana outgrew its infra - What it really takes to build reliable, multi-region RPC - Hidden pain points with latency, archive data & missing blocks - How infra

We slashed transaction latency from 5.5s → 3.75s. At 7.3M txns/week, that’s cumulative ~147 days of user wait time saved—every week. Fun example of engineering wins at scale.
