We give a universal property of the construction of the ring of $p$-typical
Witt vectors of a commutative ring, endowed with Witt vectors Frobenius and
Verschiebung, and generalize this construction to the derived setting. We
define an $\infty$-category of $p$-typical derived $\delta$-Cartier rings and
show that the derived ring of $p$-typical Witt vectors of a derived ring is
naturally an object in this $\infty$-category. Moreover, we show that for any
prime $p$, the formation of the derived ring of $p$-typical Witt vectors gives
an equivalence between the $\infty$-category of all derived rings and the full
subcategory of all derived $p$-typical $\delta$-Cartier rings consisting of
$V$-complete objects.
