We develop a formal model of Algorand stateless smart contracts (stateless ASC1.) We exploit our model to prove fundamental properties of the Algorand blockchain, and to establish the security of some archetypal smart contracts. While doing this, we highlight various design patterns supported by Algorand. We perform experiments to validate the coherence of our formal model w.r.t. the actual implementation.

A category-theoretic and topological formalization of valid UTxO ledger traces, with proofs that ledger transactions commute and are replay-safe under an injective hash assumption.
