So to understand what a radical 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 ledger.
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 upheaval 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。
