Verifying Safety Properties with the TLA+ Proof System

Kaustuv Chaudhuri, Damien Doligez, Leslie Lamport, and Stephan Merz
TLAPS, the TLA+ proof system, is a platform for the development and mechanical verification of TLA+ proofs. The TLA+ proof language is declarative, and understanding proofs requires little background beyond elementary mathematics. The language supports hierarchical and non-linear proof construction and verification, and it is independent of any verification tool or strategy. Proofs are written in the same language as specifications; engineers do not have to translate their high-level designs into the language of a particular verification tool. A proof manager interprets a TLA+ proof as a collection of proof obligations to be verified, which it sends to backend verifiers that include theorem provers, proof assistants, SMT solvers, and decision procedures.
