Commutative Replicated Data Types are a promising new class of data structures for large-scale shared mutable content in applications that only require eventual consistency. The Without Operational Transforms (WOOT) framework is a CRDT for collaborative text editing introduced by Oster et al. (CSCW 2006) for which the eventual consistency property was verified only for a bounded model to date. We contribute a formal proof for its strong eventual consistency.
