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

Frontier and Homestead era token deployment.

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 JP Shares, with the symbol JPS and 2 decimal places.
