What Is Ethereum Cryptocurrency?

Ethereum is an open-source, public, blockchain-based distributed computing platform and operating system featuring smart contract (scripting) functionality. It supports a modified version of Nakamoto consensus via transaction based state transitions. In popular discourse, the term Ethereum is often used interchangeably with Ether to refer to the cryptocurrency that is generated on the Ethereum platform.

Ether is a cryptocurrency whose blockchain is generated by the Ethereum platform. Ether can be transferred between accounts and used to compensate participant mining nodes for computations performed. Ethereum provides a decentralized Turing-complete virtual machine, the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes. “Gas”, an internal transaction pricing mechanism, is used to mitigate spam and allocate resources on the network.

The Cryptocurrency was proposed in late 2013 by Vitalik Buterin, a cryptocurrency researcher and programmer. Development was funded by an online crowdsale that took place between July and August 2014. The system went live on 30 July 2015, with 11.9 million coins “premined” for the crowdsale. This accounts for approximately 13 percent of the total circulating supply.

In 2016, as a result of the collapse of The DAO project, Ethereum was split into two separate blockchains – the new separate version became Ethereum (ETH), and the original continued as Ethereum Classic (ETC). The value of the Ethereum currency grew over 13,000 percent in 2017.

Comparison to bitcoin

Ether is different from Bitcoin (the cryptocurrency with the largest market capitalization as of January 2018) in several aspects:

  • Its block time is 14 to 15 seconds, compared with 10 minutes for bitcoin.
  • Mining of ether generates new coins at a usually consistent rate, occasionally changing during hard forks, while for bitcoin the rate halves every 4 years.
  • Transaction fees differ by computational complexity, bandwidth use and storage needs (in a system known as gas), while bitcoin transactions compete by means of transaction size, in bytes.
  • Ethereum gas units each have a price that can be specified in a transaction. This is typically measured in Gwei. Bitcoin transactions usually have fees specified in satoshis per byte.
  • Transaction fees are generally considerably lower for ether than for Bitcoin. In December 2017, the median transaction fee for ether corresponded to $0.33, while for bitcoin it corresponded to $23.
  • Ethereum uses an account system where values in Wei are debited from accounts and credited to another, as opposed to Bitcoin’s UTXO system, which is more analogous to spending cash and receiving change in return. Both systems have their pros and cons; in terms of storage space, complexity, and security/anonymity.
  • Ethereum is planned to transfer to full Proof-of-Stake, currently it is a hybrid between Proof-of-Work and Proof-of-Stake.

Supply

The total supply of ether was Ξ98 million as of January 2018. In 2017, mining generated 9.2 million new ether, corresponding to a 10% increase in its total supply. Casper FFG and CBC are expected to reduce the inflation rate to between 0.5% to 2%. There is no currently implemented hard cap on the total supply of ETH, but it is expected to end at a certain point, and become deflationary.

Markets and stores

Ether can be traded by regular currency brokers, cryptocurrency exchanges, as well as many online cryptocurrency wallets. As of January 2018, at least 150 stores accept ether.

Platform

Virtual Machine

The Ethereum Virtual Machine (EVM) is the runtime environment for smart contracts in the Crypto currency. It is a 256-bit register stack, designed to run the same code exactly as intended. It is the fundamental consensus mechanism for the Cryptocurrency. The formal definition of the EVM is specified in the Ethereum Yellow Paper. It is sandboxed and also completely isolated from the network, filesystem or other processes of the host computer system. Every Ethereum node in the network runs an EVM implementation and executes the same instructions. In February 1, 2018, there were 27,500 nodes in the main Ethereum network. Ethereum Virtual Machines have been implemented in C++, Go, Haskell, Java, JavaScript, Python, Ruby, Rust, and WebAssembly (currently under development). The Ethereum-flavoured WebAssembly (dubbed “e-WASM”) is expected to become a major component of the “Web 3.0”, a World Wide Web where users interact with smart contracts through a browser.

Smart contracts

The Cryptocurrency’s smart contracts are based on different computer language, which developers use to program their own functionalities. Smart contracts are high-level programming abstractions that are compiled down to EVM bytecode and deployed to the Ethereum blockchain for execution. They can be written in Solidity (a language library with similarities to C and JavaScript), Serpent (similar to Python, but deprecated), LLL (a low-level Lisp-like language), and Mutan (Go-based, but deprecated). There is also a research-oriented language under development called Viper (a strongly-typed Python-derived decidable language).

Smart contracts can be public, which opens up the possibility to prove functionality, e.g. self-contained provably fair casinos.

One issue related to using smart contracts on a public blockchain is that bugs, including security holes, are visible to all but cannot be fixed quickly. One example of this is the 17 June 2016 attack on The DAO, which could not be quickly stopped or reversed.

There is ongoing research on how to use formal verification to express and prove non-trivial properties. A Microsoft Research report noted that writing solid smart contracts can be extremely difficult in practice, using The DAO hack to illustrate this problem. The report discussed tools that Microsoft had developed for verifying contracts, and noted that a large-scale analysis of published contracts is likely to uncover widespread vulnerabilities. The report also stated that it is possible to verify the equivalence of a Solidity program and the EVM code.

Applications

The Cryptocurrency blockchain applications are usually referred to as DApps (decentralized application), since they are based on the decentralized Ethereum Virtual Machine, and its smart contracts. Many uses have been proposed for the Crypto currency platform, including ones that are impossible or unfeasible. Use case proposals have included finance, the internet-of-things, farm-to-table produce, electricity sourcing and pricing, and sports betting. The Crypto currency is (as of 2017) the leading blockchain platform for initial coin offering projects, with over 50% market share.

To buy the Cryptocurrency you can sign up with a cryptocurrency broker, you can use Plus500, XM, eToro, Fxpro or AvaTrade crypto currencies brokers.
