Defi without latency: Inside Etherlink's instant confirmations
summary
Etherlink cuts transaction confirmation latency from ~500 ms to about 50 ms by having the sequencer commit each tx and followers execute them incrementally, yielding measured medians of 20–30 ms nearby and a demo at 20 ms; current rollout needs a node placed close to the sequencer with a config flag and uses the draft RPC central transaction sync or two websocket streams; ordering is first come first served, 95% under 50 ms today with a goal of 99%.
