We compute the mod 2 homology of the spectrum tmf of topological modular forms by proving a 2-local equivalence tmf ∧DA(1) ≃ tmf1(3) ≃ BP 〈2〉, where DA(1) is an eight cell complex whose cohomology doubles the subalgebra A(1) of the Steenrod algebra generated by Sq and Sq. To do so, we give, using the language of stacks, a modular description of the elliptic homology of DA(1) via level three structures. We briefly discuss analogs at odd primes and recover the stack-theoretic description of the Adams–Novikov spectral sequence for tmf.
