ERC: 179
Title: Simpler Token standard
Status: Draft
Type: Informational
Created: 18-11.2016

Abstract

The following describes standard functions a token contract can implement.
This ERC describes a simpler version of the ERC20 standard token contract, removing transfer approvals.

Motivation

Some dapps need interfaces simpler than ERC20 as a base for their tokens. We've seen some projects take this approach already (1). The main problems with ERC20 standard token are:

• Lack of reference implementation and tests
• Higher complexity due to approve functionality, which not all projects need.
• Returns boolean values to signal failure instead of throwing.
• Function totalSupply() could just be implemented as a state variable in most cases.

Specification

totalSupply

uint public totalSupply;

The total token supply

balanceOf

function balanceOf(address who) constant returns (uint);

Get the account balance of another account with address who

transfer

function transfer(address to, uint value);

Send value amount of tokens to address to

Transfer event

event Transfer(address indexed from, address indexed to, uint value);

Triggered when tokens are transferred.

Reference Implementation and tests

https://github.com/OpenZeppelin/zeppelin-solidity/blob/master/contracts/token/BasicToken.sol
https://github.com/OpenZeppelin/zeppelin-solidity/blob/master/test/BasicToken.js

As you can see, the code is simpler and very concise. Comments appreciated.
