TED演讲:区块链对货币和商业的影响(6)

 So to understand what a radical¹ change this is going to bring, let's look at one industry, financial services. 所以为了理解即将到来的突破性的改变，让我们看一个行业：金融服务业。

Recognize this? Rube Goldberg machine. 你们能否认出这是什么？小题大做的机器。

It's a ridiculously complicated machine that does something really simple, like crack an egg or shut a door. 这台机器离奇地复杂，工作却很简单，像是敲碎鸡蛋或是关上门等。

Well, it kind of reminds me of the financial services industry, honestly. 老实说，它使我想起了金融服务业。

I mean, you tap your card in the corner store, 我的意思是，你在街角的商店刷了卡，

and a bitstream goes through a dozen companies, each with their own computer system, 一股比特流便穿过了好几家公司，每一家都有自己的计算机系统，

some of them being 1970s mainframes, older than many of the people in this room, and three days later, a settlement occurs. 其中还有一些20世纪70年代的主机，甚至比在座的各位还要老，然后三天过后，一份交易说明诞生了。

Well, with a blockchain financial industry, there would be no settlement, 好吧，金融业有了区块链，将不再会有交易说明，

because the payment and the settlement is the same activity, it's just a change in the ledger². 因为交易和交易说明是同一种行为，它只是在账本中有所不同。

So Wall Street and all around the world, the financial industry is in a big upheaval³ about this, 所以在华尔街或世界上所有地方，金融业正在巨变，

wondering, can we be replaced, or how do we embrace this technology for success? 思考着自己是否会被取代，或是如何正视技术迎接成功？

Now, why should you care? Well, let me describe some applications. 现在为什么要在意呢？让我来讲述几个应用吧。
