A measure, not a coin
A measure that answers to real goods, not to someone else's debt.
The Lydian is a measure of productive capacity for the Reserve, not a coin you trade — denominated against a basket of real-world commodities, so it can't be inflated away by policy.
A basket of real-world commodities backs the Lydian's value — algorithmic, transparent, and not issued by a central bank. Where fiat currency answers to a monetary authority's policy decisions, the Lydian answers to the basket itself: verifiable by anyone, manipulable by no one.
This is what "sound money" means in practice — a unit of account that holds its value across the same seven-generation horizon everything else in this architecture is built for, rather than one that quietly erodes a little every year by design.
Origin
Named for the Lydian Lion — the first standardized coinage in history, struck circa 600 BCE. The first time a civilization decided a coin's value should be trustworthy on its face, wherever it traveled. The Lydian carries that idea forward.
