We introduce the hash history mechanism for capturing dependencies among distributed replicas. Hash histories, consisting of a directed graph of version hashes, are independent of the number of active nodes but dependent on the rate and number of modifications. We present the basic hash history scheme and discuss mechanisms for trimming the history over time. We simulate the efficacy of hash histories on several large CVS traces. Our results highlight a useful property of the hash history: the ability to recognize when two different non-commutative operations produce the same output, thereby reducing false conflicts and increasing the rate of convergence. We call these events coincidental equalities and demonstrate that their recognition can greatly reduce the time to global convergence.
