比特币如何进行托管服务

Bitcoin是革命性的，在其交易难以追查和不可逆转的。但随着经济的大系统，大的变化，必须慢慢来 。我们是用来处理与收益，扭转交易，我们不快乐的，类似的事情-所以Bitcoin需要通过所有这些机制 。我们需要匿名的，值得信赖的  托管。
你不希望有人不过信任的基础上，建立一套房子。您希望看到的资金，准备支付给你，对你的工作的完成和接受。同样，房主要收据，她付出的资金，这房子是她的。建设者和未来的房主都需要信任相互信任的中介。这是今天在bitcoin生态系统缺乏。
BITCOIN
这四个障碍是什么Falkvinge标识Bitcoin的四大障碍，这将是一系列Bitcoin的四位车手在一系列文章。这是第三篇文章中，对  代管。其他  可用性，交易，  交流。
有几个新生escrows，ClearCoin一样，但我们需要更多，更-多尺度。此外，没有任何存在的代管服务有任何任何时间在社区建立信任的。escrows需要提供自由裁量权和匿名性，就像bitcoin经济作为一个整体需要，使他们的客户是不会对合法暴力的机关和其他实体暴露的保障 。
托管业务的情况下是显而易见的 - 它需要一个交易的一小部分。今天的信用卡公司采取的5％左右。ClearCoin需要的十分之一。有商人和escrows同样的商业案例。
代管服务需要三个具体的尺度，既不是今天开会。
第一代管是个人的规模 。你买从另一个人的东西。我预测NFC将会对用户最友好的技术：使用的情况下将是站在卖方和买方面对对方，并提高他们的手机，把他们背靠背，这样既看到对方和自己的屏幕 。卖方进入她的电话号码。买方按下一个按钮，确认交易 。随即，卖方都知道，现在议定数额的资金属于她。无论是买方还是卖方的资金风险损失从丢失的手机 。无论是买方还是卖方都亲自确定。在接下来的半小时左右，bitcoin网络追上，所以有可能，她不能立即花费的资金。这不是相关的情况下 。据我所知，没有人还工作在此Android和/或iPhone的情景 。
第二个代管点的销售规模。这是从买方的角度来看，个人的规模颇为相似，黑色表面上，除了他的地方他的电话在一个销售点。从卖方的角度来看，卖方要求买方支付授权通过买方的手机销售，就像个人的规模，，但店员很可能与附加NFC通信表面触摸屏。这代管方案正在积极从多种角度。
第三代管是  国际贸易的规模，今天使用的信用证。价值数百万美元的交易，航运时间的几个容器。需要成为这个成功远远不是一个网站-了解这种规模的买家和卖家的要求超出了我的经验范围，但值得信赖的收据，自由裁量权，并保护合法的搜索是一定要的要求。ClearCoin去朝着这一点点，但我认为还需要更多资金。
在两天中，我将结束这个系列Bitcoin的障碍，最后交流 。之后，我将开始有关Bitcoin的四名司机热情。有至少四个Bitcoin司机，其中每一个将要转换成欧元和美元的十亿美元的Bitcoin，如果被清除的障碍。

以上GOOGLE翻译英文原文如下:

Bitcoin is revolutionary in that its transactions are untraceable and irreversible. But in a system as large as The Economy, large changes must come gradually. We are used to dealing with receipts, reversing transactions we’re not happy with, and similar things — so Bitcoin requires all those mechanisms for adoption. We need anonymous, trustable escrow.
You don’t want to build a house for someone based on nothing but trust. You want to see the funds there, ready to be paid out to you on completion and acceptance of your work. Similarly, the homeowner wants a receipt that she paid the funds, that the house is hers. The builder and future homeowner both need to trust a mutually trusted intermediary. This is lacking in the bitcoin ecosystem today.
BITCOIN’S FOUR HURDLES
This is an article in a series on what Falkvinge identifies as Bitcoin’s four hurdles, which will be followed by a series on Bitcoin’s four drivers. This is the third article, on escrow. The others are usability, transactions, and exchanges.
There are a few nascent escrows, like ClearCoin, but we need more, much more — and on more scales. Besides, none of the escrow services that exist have had any time whatsoever for building trust in the community. The escrows need to provide discretion and anonymity just like the bitcoin economy as a whole, and need to make safeguards that their clients are not exposed towards authorities and other entities capable of lawful violence.
The business case for escrow is obvious — it takes a small fraction of the transaction. Today’s credit card companies take about 5%. ClearCoin takes one-tenth of that. There’s the business case for merchants and escrows alike.
The escrow services are needed on three specific scales, and neither is met today.
The first escrow is the personal scale. You’re buying something from another person. I predict NFC will be the most user-friendly technology here: the use case would be that seller and buyer stand facing each other, and both raise their phones, placing them back to back, so that both see each other and their own screen. The seller enters a number on her phone. The buyer presses a button confirming the transaction. Immediately, the seller knows that the agreed amount of funds now belongs to her. Neither buyer nor seller risk loss of money from loss of phone. Neither buyer nor seller are personally identified. Over the next half-hour or so, the bitcoin network catches up, so it is possible that she can’t spend the funds immediately. That’s not relevant for the scenario. From what I know, nobody is yet working on this scenario for Android and/or iPhone.
The second escrow is the point-of-sale scale. This is quite similar to the personal scale from the buyer’s point of view, except he places his phone on a black surface at a point-of-sale. From a seller’s perspective, the seller asks the buyer to pay by authorizing the sale through the buyer’s phone, just like on the personal scale, but the sales clerk is likely to operate a touchscreen with an attached NFC communications surface. This escrow scenario is actively being worked on from several angles.
The third escrow is the international trade scale, where Letters of Credit are used today. Million-dollar deals, shipping several containers at a time. It takes much more than a website to become successful with this — understanding requirements for buyers and sellers on this scale goes beyond the scope of my experience, but trustable receipts, discretion, and protection from lawful searches is certain to be three of the requirements. ClearCoin goes a little bit towards this, but I believe much more is needed.
In two days, I will end this series with the last of Bitcoin’s hurdles, exchanges. After that, I will start being enthusiastic about Bitcoin’s four drivers. There are at least four drivers for Bitcoin, each of which is going to convert billions of euros and US dollars into Bitcoin if the hurdles are cleared.
