实际上，它确实是一次下载 500 个区块，然后在验证区块时，计数器会逐个计数。
让比特币下载并验证区块的好处是，你不必信任向你提供下载的人。如果你从某个网站下载 blk*.dat 文件，就必须信任那个网站，因为你会在未亲自验证的情况下接受这些数据。如果你是从自己的另一台计算机复制 blk*.dat，那应该没问题。
你的初始区块下载要花多长时间？

It does in fact download 500 blocks at a time, then the counter counts one at a time as it verifies the blocks.
The advantage of letting bitcoin download and verify the blocks is that you do not have to trust the person you're downloading them from. If you downloaded the blk*.dat files from some site, you would have to trust that site, since you would be accepting the data without verifying it yourself. If you're copying blk*.dat from another computer of yours, that should be fine.
How long is the initial block download taking for you?
