1. What is Ethereum coin?
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference.
These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property. This enables developers to create markets, store registries of debts or promises, move funds in accordance with instructions given long in the past (like a will or a futures contract) and many other things that have not been invented yet, all without a middle man or counterparty risk.
The project was bootstrapped via an ether pre-sale during August 2014 by fans all around the world. It is developed by the Ethereum Foundation, a Swiss nonprofit, with contributions from great minds across the globe.
2. Is it Smart money, smart wallet?
The Ethereum Wallet is a gateway to decentralized applications on the Ethereum blockchain. It allows you to hold and secure ether and other crypto-assets built on Ethereum, as well as write, deploy and use smart contracts.
3. What’s Technical used?
On traditional server architectures, every application has to set up its own servers that run their own code in isolated silos, making sharing of data hard.
If a single app is compromised or goes offline, many users and other apps are affected.
On a blockchain, anyone can set up a node that replicates the necessary data for all nodes to reach an agreement and be compensated by users and app developers.
This allows user data to remain private and apps to be decentralized like the Internet was supposed to work.
Create a tradeable digital token that can be used as a currency, a representation of an asset, a virtual share, a proof of membership or anything at all. These tokens use a standard coin API, so your contract will be automatically compatible with any wallet, other contract or exchange also using this standard.
The total amount of tokens in circulation can be set to a simple fixed amount or fluctuate based on any programmed ruleset.
Issue your token
Ethereum can be mined with modern GPU hardware, just like Bitcoin in old good years. How about ETH mining profabilty?
You can easily mine Ethereum on any PC with Windows or Linux. You need a fast GPU like AMD R9 290X, AMD 7870, AMD R7 370, GTX 960. These cards enable Ethereum mining with 10-25 MH/s.
