Bitcoin explained and made simple | Guardian Animations

《卫报》 全图

简单介绍比特币
Bitcoin made simple
比特币是一种电子货币
Bitcoin is a digital currency,
是解决我们在线支付问题的一种方式
which aims to do a way of all the problems we have paying for things online.
你可能认为我们现有的体系相当好
You may think the system we have is pretty good,
但是今天我们买的每样东西都不得不通过
but everything we buy today has to go through a bank or credit card company
削减交易的银行或者
who take a cut to the transaction
依赖我们信用的信用卡公司来做所有事
and who rely on our trust that’ll do everything right.
之后那些支付方式开始兴起
After a while those payments start to build up,
还附加了担保作用
and added to that to security.
你必须相信你的信用卡公司能保证你的信息安全
You have to trust your card company to keep your details safe.
许多人尝试做出一个没有中间人的支付体系
Many people try to work out how to have a payment system without that middleman,
但当时还有另一个问题
but then there’s another problem.
你怎样证明你已经支付过某东西
How do you prove that you’ve paid for something,
甚至你是有那笔钱的
or even that you have that money at all
在没有任何人给你担保的情况?
without someone vouching for you?
这样一个名为双重开支的问题
It’s so serious it has a name
是十分严重的
the double spending problem.
然后在2008年
Then in 2008,
一个笔名为Satoshi Nakamoto的
a solution was offered by an anonymous programmer going
匿名程序员提出了一个解决方案
by the name of Satoshi Nakamoto.
Nakamoto在一个流行的密码博客写了一篇论文
Nakamoto left paper on a popular cryptography blog
其建议是一种能解决所有这些棘手问题的货币
which propose to system a currency that’ll solve all of these fiddly problems.
他的建议
His proposal was
不像银行和信用卡公司在一个中央账本上记录每笔交易
instead of a bank or credit card company recording every transaction in one central leger,
而是所有的用户都会同时被记录所有的交易
all of the users would record all of the transactions at the same time.
结果
As a result,
任何企图欺骗这个货币社区的人都会因支付被拒而被注意到
any attempt to fool the community would be noticed as the payment rejected.
没有一个用户 政府
No one user, government,
或者银行能用这种支付强制收费
or bank can force a fee in a payment,
或者控制它的发展趋势
or control its flow.
结果它成为一种更便宜 更快 更简单的花钱方式
The result is a cheaper quicker and easier way to spend money,
甚至跨越国界
even across national borders.
这就是比特币
So this is Bitcoin,
它已经开始影响人们的生活
and it has already started to have impact on people’s lifes.
在这个建议提出后的数月里 它已经被用于商品买卖了
Within months of the proposal, it was being used to buy and sell goods,
虽然还不流行于大多数谨慎的交易者中
although not always from most scrupulous traders.
但是也不全用于暗地交易
But It’s not all shady businesses,
某些购物网站用它
some shopping sites take it,
你可以在伦敦买品脱
you can buy pints in London,
甚至用来支付你的大学学费
and even pay for your university tuition.
你可能听说过
As you might have heard,
它仍存在问题
there are problems.
虽然有些人很早就从中获利
While some are profiting from getting involved early,
但也有些人却从这个动荡的年轻市场中亏损
others are losing out from this volatile young market,
人们兴办公司来买下大量的比特币
and people are founding companies to buy up lots of Bitcoins,
但是就像当初设计的 在每个流通市场中比特币的数量是固定的
but as it designed to have a limited amount every circulation,
而那样可能会导致途中出现问题
that might cause problems down the road.
比特币还有很多不确定性
There’s so much uncertainty on Bitcoinh,
一些人普遍认为它就是未来
some people generally think this is the future,
而另一些人害怕它会破坏我们的经济
others are terrify that it could destroy our economy.
但是两方中的很多人都同意
But many from both sides agree
如果我们能从工作或者类似的事里获得比特币
that if we could get Bitcoin to work or something like it,
如果我们可以信任这个没有中间人的电子货币来工作
if we can trust a digital currency to work without a middleman,
那么世界经济运行的方式可以更好地转变
then the way the world economy functions could be transformed for the better.
我们都知道
We all know that
史蒂文·霍金一直在研究一些关于我们宇宙的大问题
Stephen Hawking has worked on some of the biggest questions about our cosmos,
但是那些想法是什么呢?
but what are those ideas?
