Ethereum is a open-software platform that is operating using blockchain technology co-founded by Vitalik Buterin. Ethereum was released 2015. Ethereum gives a cryptocurrency called "ether" that can be moved from different accounts. While Bitcoin was designed for consumer payments, Ethereum was designed to allow for more complex party interactions called smart contracts.

Ethereum ERC Tokens

An Ethereum based token is a fungible tradable asset that operates on Ethereum's blockchain. The Ethereum Request for Comments (ERC) for tokens are a way of describing a set of functions and rules that the token should posses and follow. The three most common standards can be seen here:

ERC20

The ERC20 token is the most commonly used standard. As such, it is the most popular way of crowdfunding for companies running an ICO.

    • The ERC20 token required functions are:**

function totalSupply() public constant returns (uint); function balanceOf(address tokenOwner) public constant returns (uint balance); function allowance(address tokenOwner, address spender) public constant returns (uint remaining); function transfer(address to, uint tokens) public returns (bool success); function approve(address spender, uint tokens) public returns (bool success); function transferFrom(address from, address to, uint tokens) public returns (bool success); event Transfer(address indexed from, address indexed to, uint tokens); event Approval(address indexed tokenOwner, address indexed spender, uint tokens); }


Examples:

ERC223

ERC721
