I would say, yes. RiakCS sits on top of Riak and this is a snippet from the 1.3 release notes:
Introduced Active Anti-Entropy. Riak now has active anti-entropy. In distributed systems, inconsistencies can arise between replicas due to failure modes, concurrent updates, and physical data loss or corruption. Pre-1.3 Riak already had several features for repairing this “entropy”, but they all required some form of user intervention. Riak 1.3 introduces automatic, self-healing properties that repair entropy on an ongoing basis.
