  Following the work of Siddharth Venkatesh, we study the category
$\textbf{sVec}_2$. This category is a proposed candidate for the category of
supervector spaces over fields of characteristic $2$ (as the ordinary notion of
a supervector space does not make sense in charcacteristic $2$). In particular,
we study commutative algebras in $\textbf{sVec}_2$, known as $d$-algebras,
which are ordinary associative algebras $A$ together with a linear derivation
$d:A \to A$ satisfying the twisted commutativity rule: $ab = ba + d(b)d(a)$. In
this paper, we generalize many results from standard commutative algebra to the
setting of $d$-algebras; most notably, we give two proofs of the statement that
Artinian $d$-algebras may be decomposed as a direct product of local
$d$-algebras. In addition, we show that there exists no noncommutative
$d$-algebras of dimension $\leq 7$, and that up to isomorphism there exists
exactly one $d$-algebra of dimension $7$. Finally, we give the notion of a Lie
algebra in the category $\textbf{sVec}_2$, and we state and prove the
Poincare-Birkhoff-Witt theorem for this category.
