Developers can create and deploy dApps on the Ethereum platform and even issue an Ethereum-based token for use in their applications. Telos is a high-performance blockchain network that is significantly more robust and advanced than any other EVM. I'll show you how to write your first Ethereum smart contract, where we'll hold an election between two candidates. Its native cryptocurrency, Ether, is built on top of the open-source Ethereum blockchain, which runs smart contracts. The simple answer to that question is incentivization. It originates from cpp-ethereum project (where GPU mining has . Ethereum is also called Turing complete and I will explain the concept of Turing completeness in the upcoming sections. To execute these, the EVM charges a very small transaction fee in exchange for the computational power used by the smart contract.

Ethereum remains the second-largest cryptocurrency measured by market capitalization, and it has been long placed in the top list since its launch. While Bitcoin is used to track ownership of digital currency (bitcoins), ethereum focuses on running the programming code of any decentralized application. Contrary to its name, gas fees do not have anything to do with liquid fuel consumption or the impact of mining on the environment. Line 17-19: Declaring the `getCount` function which is the reason we started this journey in the first place, instantiating the interface with the `counterAddr` address and immediately calling the `count` function on it to fetch the count from the deployed `Counter.sol` contract.
