TSP-1 — Coin
the fungible token nature of plumb. one of two natures all value reduces to.
nature
| property | value |
|---|---|
| fungibility | yes — units are interchangeable |
| conservation | Σ balances(class) = supply(class) |
| identity | per token class, not per unit |
| transfer | by pay (PLUMB) |
| creation | by mint (PLUMB) |
| destruction | by burn (PLUMB) |
a Coin has a class and a supply. holders carry a balance in that class. exactly one balance per (holder × Coin-class) pair.
what a Coin represents
- currencies (CYB, USDT, IDR)
- continuous resources (kg of rice, kWh, GB-months, compute credits)
- shares of an entity (equity, voting weight)
- access credits (LLM calls, API quota, bandwidth)
conservation
for every Coin class:
Σ balances(class) = mint_total(class) − burn_total(class)
mints and burns are explicit PLUMB operations between designated source and sink Cards. the equation holds by construction — violation is unprovable.
relationship to Card
Coins are held BY Cards. a Card is a holder; a Coin balance is what it holds. accounts do not exist as a separate concept — what looks like an account is a Card with balances in some Coin classes.
