宣布比特币首次发布。这是一种新型电子现金系统，使用点对点网络来防止双重支付。它完全去中心化，没有服务器或中央机构。
Announcing the first release of Bitcoin, a new electronic cash system that uses a peer-to-peer network to prevent double-spending. It's completely decentralized with no server or central authority.

目前仅支持 Windows。包含开源 C++ 代码。
Windows only for now. Open source C++ code is included.
如果你能持续运行一个接受传入连接的节点，就能为网络提供很大帮助。你需要开放防火墙的 8333 端口，才能接收传入连接。
If you can keep a node running that accepts incoming connections, you'll really be helping the network a lot. Port 8333 on your firewall needs to be open to receive incoming connections.
软件仍处于 alpha 实验阶段。虽然我已尽力加入可扩展性和版本控制，但无法保证将来必要时不必重新启动整个系统的状态。
The software is still alpha and experimental. There's no guarantee the system's state won't have to be restarted at some point if it becomes necessary, although I've done everything I can to build in extensibility and versioning.
你可以让别人给你一些币，或打开 Options->Generate Coins，运行节点并生成区块。我把初始工作量证明难度设得低得离谱，所以刚开始的一小段时间里，普通 PC 只需几小时就能生成币。当竞争使自动调整机制提高难度时，就会困难得多。生成的币必须等待 120 个区块，成熟后才能花费。
You can get coins by getting someone to send you some, or turn on Options->Generate Coins to run a node and generate blocks. I made the proof-of-work difficulty ridiculously easy to start with, so for a little while in the beginning a typical PC will be able to generate coins in just a few hours. It'll get a lot harder when competition makes the automatic adjustment drive up the difficulty. Generated coins must wait 120 blocks to mature before they can be spent.
有两种汇款方式。如果收款人在线，你可以输入他的 IP 地址，软件就会连接过去，获取一个新公钥，并发送附有备注的交易。如果收款人不在线，你可以向他的比特币地址付款，这个地址是他提供给你的公钥哈希。下次他连接网络，获取包含该交易的区块时，就会收到这笔交易。这种方式的缺点是不传送备注信息，而且如果一个地址被多次使用，可能损失一点隐私；但如果双方无法同时在线，或收款人不能接收传入连接，它就是一种有用的替代方式。
There are two ways to send money. If the recipient is online, you can enter their IP address and it will connect, get a new public key and send the transaction with comments. If the recipient is not online, it is possible to send to their Bitcoin address, which is a hash of their public key that they give you. They'll receive the transaction the next time they connect and get the block it's in. This method has the disadvantage that no comment information is sent, and a bit of privacy may be lost if the address is used multiple times, but it is a useful alternative if both users can't be online at the same time or the recipient can't receive incoming connections.
总流通量将为 21,000,000 枚币。它们会在网络节点创建区块时分配给节点，分配数量每 4 年减半。
Total circulation will be 21,000,000 coins. It'll be distributed to network nodes when they make blocks, with the amount cut in half every 4 years.
最初 4 年：10,500,000 枚币接下来 4 年：5,250,000 枚币接下来 4 年：2,625,000 枚币接下来 4 年：1,312,500 枚币依此类推……
first 4 years: 10,500,000 coins next 4 years: 5,250,000 coins next 4 years: 2,625,000 coins next 4 years: 1,312,500 coins etc...
这些币发完后，系统可以在需要时支持手续费。这基于公开的市场竞争，而且很可能始终会有节点愿意免费处理交易。
When that runs out, the system can support transaction fees if needed. It's based on open market competition, and there will probably always be nodes willing to process transactions for free.
