52 分钟Boosters say blockchain technology will usher in a brave new era of decentralization. Are they right — and would it be a dream or a nightmare? (Part 3 of "What Can Blockchain Do for You?")
I do want to talk about one thing.
There's this concept of Web 3.0.
Chris Giancarlo, also known as Cryptodad, is a former chairman of the Commodity Futures Trading Commission, or CFTC.
We have been hearing from Giancarlo throughout this series on blockchain technology and cryptocurrencies.
So what exactly is Web 3.0?
It's a whole new architecture of things, of value, of banking, finance, and money itself.
To appreciate this new architecture, we need to backtrack a few decades.
Let's start with Web 1.0.
Web 1.0 was a pretty static online experience.
Think about using AOL dial up service and Netscape Navigator to look at websites.
Years later came companies like Facebook, building interactive platforms that encouraged a less static online experience.
This is sometimes called Web 2.0.
But people are concerned that Web 2.0 got hijacked by a number of big tech companies that not only censor what you see, they actually condition how you react to what you see.
And they've turned us, the surfers, into the product themselves.
It took years for some of us to appreciate what Giancarlo is saying here, but now we know if you are not paying for a product, the product is you.
This brings us to Web 3.0.
The promise is we can take back control.
We could actually control with great granularity who would have access to our information and what pieces of our information.
In the first two episodes of this series, we defined what blockchains are and what sort of spawn they've been generating.
Cryptocurrencies, nfts, and so called smart contracts.
