# Strict Software Transaction Memory The `strict-stm` package provides a strict interface to software transaction memory. It builds on top of [`io-classes`] and thus it provides the interface for both [`stm`] as well as [`io-sim`]. # Novel testing / space-leak elimination approach The strict interface provides a novel way of testing/eliminating space-leaks which might lurk in `stm` shared mutable variables. Together with the [`nothunks`] library it was successfully used to eliminate and keep a large system ([`cardano-node`]) space leak free.
