3/ Multi-key load balancing has enabled VRF nodes to parallelize VRF fulfillments.
In short, this means that instead of writing one fulfillment on-chain and waiting for completion, a single node can now write up to four fulfillments at the same time.
3/多键负载平衡使VRF节点能够并行化VRF实现。
简而言之，这意味着一个节点现在可以同时写入多达四个履行，而不是在链上写入一个履行并等待完成。
