@Paul Butcher I would argue that Clojure's STM implementation is very similar or based on the design of Apache CouchDB's Multi-Version Concurrency Model.
1. Immutable by default. 2. You can't corrupt a completed transaction. 3. Conflict resolution essentially gives the previous revision before the conflict occured and then gives the latest revision from there on out. 4. Depending on the type of transaction, the transaction will attempt to restart on failure Let me know if this is no longer accurate.
