也很希望看到一种无需提供和 管理货币的支持。这样维护起来会更容易、成本更低， 而且无论何时何地，都能拥有足够的货币。 没有稀缺，没有过剩，始终恰好是合适的数量， 自组织。
这是可以做到的。可以通过编程让它遵循任何一组规则。
如果你想实现像 Marc 的想法以及这里讨论的其他想法那样的可编程 P2P 社会货币，我认为比特币是一个基础和第一步。首先需要让普通、基本的 P2P 货币运转起来。一旦它建立起来并得到验证，动态智能货币就是顺理成章且容易实现的下一步。
我很喜欢虚拟的、非地域性社区试验新经济范式这个想法。
这让我想起：
- AardRock » Wizard Rabbit Treasurer http://wiki.aardrock.com/Wizard_Rabbit_Treasurer；以及
- AardRock » Pekunio http://wiki.aardrock.com/Pekunio
确实，从把每笔交易的冗余副本散发给网络中若干对等节点这一概念来看，它很像 Pekunio，但其实现并不是 Wizard Rabbit Treasurer 那样的信誉网络。事实上，比特币根本不使用信誉。它把网络视为一大群人，并不太在意自己在和谁交谈，也不在意是谁告诉它某件事，只要其中至少有一个节点会转发正在整个网络中广播的信息即可。它之所以不在意，是因为没有办法对它撒谎。你要么向它提供某件事的密码学证明，要么它就忽略你。
你熟悉 Ripple 吗？
在各种信任系统中，Ripple 的独特之处在于把信任分散开来，而不是将其集中起来。
比特币是否也有协议规范（以便支持不同的 语言绑定和实现；在规范上联合，在 实现上竞争）？
最好参考 C++ 源代码。我计划实现一些接口，以便用任何语言使用该软件发送和接收交易，这样服务器端代码就能轻松地把它用于基于 Web 的电子商务网站。

That's do-able. It can be programmed to follow any set of rules.
I see Bitcoin as a foundation and first step if you want to implement programmable P2P social currencies like Marc's ideas and others discussed here. First you need normal, basic P2P currency working. Once that is established and proven out, dynamic smart money is an easy next step.
I love the idea of virtual, non-geographic communities experimenting with new economic paradigms.
Reminds me of:
- AardRock » Wizard Rabbit Treasurer http://wiki.aardrock.com/Wizard_Rabbit_Treasurer; and
- AardRock » Pekunio http://wiki.aardrock.com/Pekunio
Indeed, it is much like Pekunio in the concept of spraying redundant copies of every transaction to a number of peers on the network, but the implementation is not a reputation network like Wizard Rabbit Treasurer. In fact, Bitcoin does not use reputation at all. It sees the network as just a big crowd and doesn't much care who it talks to or who tells it something, as long as at least one of them relays the information being broadcast around the network. It doesn't care because there's no way to lie to it. Either you tell it crypto proof of something, or it ignores you.
Are you familiar with Ripple?
As trust systems go, Ripple is unique in spreading trust around rather than concentrating it.
Is bitcoin also available as a protocol spec (facilitating differen language bindings and implementations; unite on specs, compete on implementation).
It would be best to refer to the C++ source code. I plan to implement interfaces for using the software to send and receive transactions from any language, so server side code can easily use it for web based e-commerce sites.
