:::note[Details pending]
:::

<p>{"A network program is a Secret Program the whole network depends on, so chain votes approve how it runs. Secret Money is a network program."}</p>

<p>{"A chain vote names the software Secret Money runs and which validators' machines may run it."}</p>

<p>{"One of those machines at a time holds the right to write Secret Money's records. The others stay ready to take over."}</p>

<p>{"Secret Money regularly records a checkpoint of its state on the chain, and the chain accepts it only from the machine currently writing."}</p>

<p>{"No other program can move Secret Money's coins, hold its funds, or read its records."}</p>
