So, the question is: can distributed ledger technology, can blockchain technology be used
to fight fake news?
And you know it’s funny, I view distributed ledger technology as the closest thing we
have in the technology field to being able to say something is a fact.
If we’ve recorded a Bitcoin transaction, essentially we have an entire network witnessing
that I’ve sent you some number of Bitcoin or some number of a digital asset, a huge
And now I can’t deny that I made that transaction and you can’t deny that I made that transaction
and that is a really powerful thing.
在某种程度上 他就像维基百科 有人在上面发布东西
In a way it’s kind of like Wikipedia when somebody puts something in there and everyone
每个人都可以浏览 如果它是错误的就删除 有一些
has seen that and if it’s wrong it gets removed, that’s something as well that’s coming
to be accepted as factual.
So I think the possibility of using distributed ledgers to record data that is of really high
quality because it’s being recorded when it happens, it’s being witnessed by a large
number of people and thus made undeniable, immutable, in this ledger.
We have a chance of creating a body of data that can come to be trusted in a way that
data normally can’t.
Think about the debate over climate change; there’s not only been attacks on, ‘Do you
have the right weather model?
Are you really showing this?’ but attacks on the fundamental collection of that data
in the first place.
Imagine if instead of debating whether you had the right data or I had the right data
or a piece of data goes missing or an entire dataset goes missing when there’s a change
in political administration, let’s say, instead of that imagine if instead we had
weather sensors and air quality sensors on a hundred rooftops in every major capital
around the world collecting this data and publishing it to a public ledger.
That data would never go away.
It would only go away if every single server in this network were to disappear one day.
而数据的永久性 历史性和完整性 因为数字签名而有效
And that permanence, that history and the integrity of that data, because it’s signed
and it’s validated as part of this distributed ledger, would turn it into an immutable set
of facts really.
It was this temperature in New Delhi on that date at that time as witnessed by a hundred
different witnesses there.
So that’s one way in which distributed ledger technology might help us make sure that we’re
operating from a foundation of common sense, common factual evidence.
The next tier up though, which is really what people talk about when they think about fake
分析 解释 声明 和谣言
news, is analysis, interpretation, claims, but also rumor.
When somebody hears a rumor of something very scurrilous happening and it correlates with
他们相信什么 可能他们会相信 并将其分享给
what they want to believe, chances are they’ll believe it and they’ll pass it off to their
所以你开始看到到一些公司 像Facebook 谷歌和其他开始应用这种系统的公司
And so you start to see companies like Facebook and Google and others starting to implement
systems that when you forward a link to a friend that comes from a source that is known
to be of questionable quality, they’ll pop up a little warning that says, ‘According
路网 美联社或某些人 这篇文章可能不属实
to Snopes.com or according to the AP or somebody this article might not be factual.’
若你是信息提供者 像Facebook或谷歌 你也可以做这些事
That’s something you can do when you’re a central provider like Facebook or like Google,
but wouldn’t it be great to do that in a decentralized way?
When somebody sends you a news link to a website you’ve never heard of before, not The New
不是纽约时报 美联社或福克斯新闻 也不是一些你了解
York Times, not AP or Fox News or whatever, where you have some context, but it’s some
other link somewhere else, how much should you trust that?
Well a lot of folks have talked about building a distributed ledger system for recording
thrust in media sources.
所以把我们了解的网站和人 比如路网 当做权威
So here’s a website, here’s people that we recognize, like Snopes, as authorities
on whether something is true or not, but why not you be able to publish something to that
chain as well, or me, that says, ‘This does seem to be right to me or this doesn’t seem
to be right.’
And then just like on Twitter where you can choose who you follow, you could choose what
are the sources of authority that you trust as to whether something is true or not.
That may turn out to be an answer to the fake news problem, or it may turn out to make the
different worlds that we all live in and the bubbles we live in even more bubblelicious.
I think there are many who hope that is one way in which we can try to fight the rumor
mongering and fake news floods that are happening on the Internet today.
