[p2p-research] Bitcoin P2P e-currency v0.1 released
P2P Research List · 2009-02-13 18:52:41 UTC
宣布发布比特币，一种全新的开源点对点电子现金
系统，完全去中心化，没有中央服务器或可信方。用户自己持有加密
密钥来保管自己的钱，彼此直接交易，并借助点对点网络
检查双重支付。
支持 Windows NT/2000/XP/Vista。附带开源 C++ 代码。

- 把文件解压到一个目录
- 运行 BITCOIN.EXE
- 它会自动连接到其他节点
如果你能让一个接受入站连接的节点保持运行，你就真的在
帮网络大忙了。你防火墙上的 8333 端口需要开放，才能接收入站连接。
你可以通过别人给你转账来获得币，或者打开
Options->Generate Coins，让一个节点运行并生成区块。我把
工作量证明难度一开始设得非常非常低，所以在最初的一小段时间里，
一台普通的电脑只需几个小时就能生成币。当竞争加剧，自动
调节推高难度时，难度会难得多。生成的币必须等待 120 个区块成熟，
之后才能花费。
发送货币有两种方式。如果接收方在线，你可以
输入他们的 IP 地址，它会连接，获取一个新的公钥，然后带着
评论发送交易。如果接收方不在线，可以发送到他们的比特币地址，
也就是他们给你的其公钥的哈希。他们下次连接并获取到
包含这笔交易的区块时，就会收到这笔交易。这种方式的缺点
是没有评论信息被发送，而且如果一个地址被多次使用，可能会
损失一点隐私，但如果双方不能同时在线，或接收方无法接收
入站连接，这是一个实用的替代方案。
总流通量将是 21,000,000 币。它们将随着区块的生成分发给
网络节点，每 4 年减半一次。
前 4 年：10,500,000 币
后 4 年：5,250,000 币
再后 4 年：2,625,000 币
再后 4 年：1,312,500 币
依此类推……
当分发完毕后，如有需要，系统可以支持交易费。
它是基于公开市场竞争的，很可能永远都有愿意免费
处理交易的节点。

英文原文
Announcing the release of Bitcoin, a new open source peer-to-peer
electronic cash system that's completely decentralized, with no central
server or trusted parties. Users hold the crypto keys to their own
money and transact directly with each other, with the help of the P2P
network to check for double-spending.
Windows NT/2000/XP/Vista. Open source C++ code is included.

- Unpack the files into a directory
- Run BITCOIN.EXE
- It automatically connects to other nodes
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.
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.
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.
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.
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...
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.
