Gulf Stream
Plain English
Instead of waiting for transactions to be included in a block, Gulf Stream forwards them directly to upcoming block producers ahead of time. It’s like calling ahead to reserve a table at a restaurant instead of waiting in line when you arrive.
Technical
Mempool management protocol that pushes transactions to validators before they become leaders. Clients forward transactions to expected leaders based on the leader schedule, allowing validators to execute transactions ahead of time and reduce confirmation latency. This eliminates traditional mempool backlogs and enables sub-second confirmation times.
