Historical Significance

The ethereum.org token tutorial is where most people who deployed a token in this period started, and this is its opening form: a balance mapping, a guarded subtraction and the metadata a wallet needs to show a name. It has no allowance, so nothing can spend on a holder's behalf and no exchange or escrow can be given a limit. That gap is exactly what ERC-20 was written to close, and copies like this one are the before picture.

Context

By late 2016 ERC-20 had settled the interface a token was expected to answer, and the ethereum.org tutorial was still where most people copied one from. OpenZeppelin's contracts were not yet the default, so the code behind a token of this period is usually the tutorial's, with the constructor arguments changed and nothing else.

Description

A token from the ethereum.org tutorial. Balances sit in a public balanceOf mapping and transfer(to, value) moves them, throwing rather than returning false when the sender is short and checking the recipient's balance for overflow before adding to it. There is no owner and no way to create further units: the supply written at deployment is the whole supply. It was deployed as test34, with the symbol test34 and 0 decimal places and it answers standard() with the string Token 0.1, the label the tutorial used before ERC-20 had a number.
