Blockchain: Bitcoin, Ethereum & Blockchain: The Beginners Guide to Understanding the Technology Behind Bitcoin & Cryptocurrency (The Future of Money Box Set)

In terms of Ethereum, we can think of all of these different computers merging together, in a sense, to form one giant computer capable of performing distributed computations. This concept is known as the “Ethereum Virtual Machine,” often abbreviated to EVM.

The Lightning Network works by allowing peer-to-peer micro-transactions to happen instantaneously using blockchain smart contracts, but without adding individual transactions to the main blockchain. The Lightning Network also supports “atomic swaps” between different blockchains, i.e. from one cryptocurrency to another, so long as those chains supp

If any node on the Ethereum network got stuck running a program in an infinite loop, it would effectively halt the entire system, hence being called “the halting problem.”

One application that runs on Ethereum is a digital currency, which is often also referred to as “Ethereum,” although technically it is called Ether.

So, smart contracts are written in one language, usually Solidity, and then compiled (using a special program called a “compiler”) into the low-level code that can be processed by the EVM environment.

You can’t swing a cat in cyberspace without hitting an ICO developing a new Ethereum-based application that promises to make early investors into millionaires.

One result of the ICO model in the Ethereum space is that we end up with companies holding a lot of Ether, rather than individuals, per se. In terms of Ether as a currency, it is important to consider the implications of having large amounts of Ether tied up in companies.

Many within the larger blockchain community see this move as counterintuitive, as much of the appeal of blockchain architecture is related precisely to the fact that it is decentralized, open, and eliminates the need for trust in a third party. Skeptics have raised the question of how “private blockchains” will differ, fundamentally, from intranets

One of the things that make Ethereum’s blockchain different than Bitcoin’s is that “transactions” that happen on the Ethereum blockchain can actually trigger code to be executed.
