Vitalik Buterin industrial-revolution revolution time I remember knowing, for a while, for a long time, that I was kind of abnormal in some sense. Vitalik Buterin long-time time remember long 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. Vitalik Buterin great money serious language 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. Vitalik Buterin understand police society cheating 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. Vitalik Buterin digital easy giving world 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. Vitalik Buterin true thought good sound 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. Vitalik Buterin customer doing job work You could imagine something like a completely automated system for renting bikes that's just done completely over blockchain crypto-payments. And theoretically just sort of start it up, and it works completely autonomously. Vitalik Buterin something start you done 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. Vitalik Buterin place good you way The main advantage of blockchain technology is supposed to be that it's more secure, but new technologies are generally hard for people to trust, and this paradox can't really be avoided. Vitalik Buterin new trust technology people 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.

The opposition to just doing things on a public blockchain is definitely smaller than some of the strongest detractors think. Vitalik Buterin doing things think happy The technical side of Ethereum's efficacy is 100% an engineering exercise. Vitalik Buterin technical side engineering exercise I think people don't realise that running a piece of code that verifies some conditions for a financial transaction, that by itself is a lot less work than verifying a cryptographic signature, and so even if the virtual machine is inefficient, the cryptographic signature is still going to dominate. Vitalik Buterin some think work people 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. Vitalik Buterin blockchain single process moving Initially, I thought that Ethereum was a thing that would be used for people to write simple financial scripts.
