中本聪就“来源未知”的处理回复 Mike Hearn（2009 年 4 月 18 日）
首次公开证据
打开首次公开证据收到了 50。
发送到比特币地址的交易总会显示“来源：未知”。交易只会说明它发送给谁。通过比特币地址发送有一些问题，但能够把它作为备用选项，向任何人发送，无论对方是否在线，这一点非常好。之后可以尝试一些改进方案。目前，如果事情发展得像现实世界一样——绝大多数交易都是与商家进行的——那么他们几乎总会确保设置为通过 IP 接收。点对点文件共享网络在让相当大比例的用户设置防火墙转发端口方面，似乎相当成功。
“已生成（未接受）”通常发生在两个节点几乎同时找到一个区块时，其中一个不会被接受。这是正常且不可避免的。我计划在 v0.1.6 中隐藏这些记录，因为它们只会让人困惑和烦恼，用户没有理由必须看到它们。在网络还像现在这样规模很小时，如果你无法接收传入连接，就会处于更不利的地位，因为你无法直接接收区块公告。

Got the 50.
Transactions sent to a bitcoin address will always say "from: unknown". The transaction only tells who it's to. Sending by bitcoin address has a number of problems, but it's so nice having the fallback option to be able to send to anyone whether they're online or not. There are a number of ideas to try to improve things later. For now, if things work out like the real world where the vast majority of transactions are with merchants, they'll pretty much always make sure to set up to receive by IP. The P2P file sharing networks seem fairly successful at getting a large percentage of their users to set up their firewalls to forward a port.
The "Generated (not accepted)" normally happens if two nodes find a block at close to the same time, one of them will not be accepted. It's normal and unavoidable. I plan in v0.1.6 to hide those, since they're just confusing and annoying and there's no reason for users to have to see them. While the network is still small like it is now, if you can't receive incoming connections you're at more of a disadvantage because you can't receive block announcements as directly.
