“Blockchains will drop search costs, causing a kind of decomposition that allows you to have markets of entities that are horizontally segregated and vertically segregated.”

“Scalability is this idea of coming up with a blockchain that can scale much larger than existing chains essentially by processing transactions in parallel. And moving away from this paradigm where every single node on the network has to process every single transaction.”

“Giving users easy access to many different kinds of digital assets on the blockchain and, particularly, tokens that are linked to assets in the real world, is crucial to seeing blockchain adoption reach the next level, and I applaud Digix Global's initiative in being the first of many such projects to successfully launch.”

“Initially, I thought that Ethereum was a thing that would be used for people to write simple financial scripts. As it turns out, people are writing stuff like Augur on top of it.”

“When I came up with Ethereum, my first first thought was, 'Okay, this thing is too good to be true.' As it turned out, the core Ethereum idea was good - fundamentally, completely sound.”

“The Ethereum client is literally a fork of Chromium's webkit backend. The idea is that users can build their own interfaces with HTML/JavaScript just like websites, and they will be viewable with the browser much like websites are viewable with the web browser.”

“I think Bitcoin really feels empowering in a sense.”

“The technical side of Ethereum's efficacy is 100% an engineering exercise.”

“I personally like hard forks. Particularly, I like the fact that they give users a measure of control, requiring them to opt in to protocol changes. Sure, they can be a little more chaotic if they're controversial, but that's the price of freedom.”

“When I was in grade five or six, I just remember quite a lot of people were always talking about me like I was some kind of math genius. And there were just so many moments when I realized, like, okay, why can't I just be like some normal person and go have a 75% average like everyone else.”

“In general, signalling theory says that if you have a good way of proving something and a noisy way of proving something, and you choose the noisy way, that means chances are it's because you couldn't do the good way in the first place.”

“A smart contract is a mechanism involving digital assets and two or more parties, where some or all of the parties put assets in, and assets are automatically redistributed among those parties according to a formula based on certain data that is not known at the time the contract is initiated.”

“Bitcoin is great as a form of digital money, but its scripting language is too weak for any kind of serious advanced applications to be built on top.”

“There is definitely a lot of banks that are interested in private blockchains. In some cases, they are happy with public blockchains as well. The opposition to just doing things on a public blockchain is definitely smaller than some of the strongest detractors think.”

“The thing that I often ask startups on top of Ethereum is, 'Can you please tell me why using the Ethereum blockchain is better than using Excel?' And if they can come up with a good answer, that's when you know you've got something really interesting.”

“You can write anything that you would be able to write on a server and put it onto the blockchain. Instead of Javascript making calls to the server, you would be making calls to the blockchain.”

“As society becomes more and more complex, cheating will in many ways become progressively easier and easier to do and harder to police or even understand.”

“I remember knowing, for a while, for a long time, that I was kind of abnormal in some sense.”

“Whereas most technologies tend to automate workers on the periphery doing menial tasks, blockchains automate away the center. Instead of putting the taxi driver out of a job, blockchain puts Uber out of a job and lets the taxi drivers work with the customer directly.”

“I personally, generally, don't really feel much emotion if there's some problem and I'm actively solving it.”
