Twenty five indivisible units standing for kilowatt hours of wind generation.

Historical Significance

The central minter is the tutorial's answer to what a currency is for, and it is a candid one: a named issuer holds the opening supply, can create more units at will, and can freeze any account's ability to send. Nothing about that is hidden or revocable. Tokens of this shape are the reason later standards separated the ledger from the policy that governs it, and the reason a reader of a token contract learns to look for who can mint before anything else.

Context

Deployed in February 2016, in the closing weeks of the Frontier era.
