我想把状态栏显示的区块数减 1。这样程序第一次加载时，会显示 0 个区块而非 1：
I'd like to reduce the number of blocks displayed in the status bar by 1. When you first load the program, it'll display 0 blocks instead of 1:
"0 connections 0 blocks 0 transactions"
"0 connections 0 blocks 0 transactions"
它一直是 "nBestHeight + 1"，因为把创世区块也数了进去。严格来说，是的，创世区块是一个区块。它是你出发时就带着的硬编码区块。你不可能没有创世区块。也许可以把它想成一枚基准币，其他币都拿它来衡量。人们想看的区块数，其实是他们下载到的区块数量。
It's always been "nBestHeight + 1" because it's counting the genesis block. Technically, yes, the genesis block is a block. It's a hardcoded block that you start out with. You can't not have the genesis block. Maybe think of it as a reference coin that you measure other coins against. The block count people are looking for is the number of blocks they've downloaded.
主要的好处是区块数会等于当前最佳区块的区块号。如果区块数是 10，那么你拥有的最高区块号就是 10。意味着你有 10 号区块，没有 11 号区块。
The main benefit is that blocks will be equal to the block number of the current best block. If blocks is 10, then the highest block number you have is 10. It means you have block 10 and you don't have block 11.
它能减少我们在这里遇到的困惑：
It would reduce the confusion we had here:
其他参与者原话kencausey原帖 ↗我自己也在这上面犯过迷糊，后来在 #bitcoin-dev 问清楚了：
I had some confusion on this myself and got clarification in #bitcoin-dev:
坏区块是 74638 号，最后一个好区块是 74637 号。编号从 0 开始，所以当你的客户端显示有 74638 个区块时，意味着你拥有到 74637 号为止的区块，也就是最后一个好区块。
The bad block was number 74638, the last good one was 74637. The numbers start at 0, so when your client shows there are 74638 blocks then that means you have up to block number 74637, the last good one.
