$FOGO’s 40ms block target with the Firedancer client isn’t the headline.
Permissionless validator co-location is.
When physical proximity determines latency, infrastructure access becomes advantage. On most chains, searchers pay for private co-location. FOGO makes low-latency positioning protocol-defined and public.
That shifts builder assumptions.
Instead of designing around partial execution risk, where step one succeeds, step two times out, and step three reverts, composable DeFi can assume atomic cross-program execution either completes fully or fails cleanly.
SVM enables parallel execution.
What matters more is whether multi-step transactions feel deterministic under load.
With 40ms block cadence and colocated validators, FOGO is betting execution certainty matters more than peak TPS.
Early activity remains measured. Validator participation is expanding, but public DeFi deployments are still selective. That is normal. Serious teams stress-test infrastructure before adversarial MEV dynamics emerge.
Benchmarks prove throughput.
Adversarial flow proves architecture.
Speed is easy when there is no economic incentive to break composability. Real validation comes when profit is on the line and atomicity still holds.
