We present the spinal atomic lambda-calculus, a typed lambda-calculus with explicit sharing and atomic duplication that achieves spinal full laziness: duplicating only the direct paths between a binder and bound variables is enough for beta reduction to proceed. We show this calculus is the result of a Curry–Howard style interpretation of a deep-inference proof system, and prove that it has natural properties with respect to the lambda-calculus: confluence and preservation of strong normalisation.
