An ethereum.org tutorial token deployed with no name and no symbol, with a fixed supply and direct transfers only.

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.

This deployment left the name and the symbol empty. Both are set once in the constructor and no function changes them, so the token has no display identity of any kind and never will: a wallet holding it can only ever show its address.

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.
