What nobody can change.

From what you control, to what nobody controls — softest to hardest.

Some things about Tallystick are yours. Some things are nobody’s. The boundary between them is the product.

Yours

Your balance. Only you can move it — no other account is given a function that touches it.
Your trades. You choose when to trade, and each one pays the visible 2% Paring.
The call. Anyone, including you, may call a Tallage whenever the gathered Paring makes one worth calling.

Nobody’s

The Paring. Fixed at 2%, written without a setter. Neither the deployer, nor a vote, nor a later version can adjust it.
The order. The Scoreline is worked in opening order, and no function anywhere marks a younger Notch first.
The supply. It began at 900,000 TALL and only shrinks. No function creates a unit; no function returns Char to supply.

Why it is built this way

A rule that can be changed is a promise. A rule written without a setter is a fact. Tallystick keeps its list of promises empty: everything the mechanism does is a fact you can read, and the short list above is everything it does.
